Spam and phishing in 2016

2016 saw a variety of changes in spam flows, with the increase in the number of malicious mass mailings containing ransomware being the most significant.

These programs are readily available on the black market, and in 2017 the volume of malicious spam is unlikely to fall.

Researchers work to save trusted computing apps from keyloggers

SGX needs I/O protection, Austrian boffins reckon Intel's Software Guard Extensions started rolling in Skylake processors in October 2015, but it's got an Achilles heel: insecure I/O like keyboards or USB provide a vector by which sensitive user data could be compromised. A couple of boffins from Austria's Graz University of Technology reckon they've cracked that problem, with an add-on that creates protected I/O paths on top of SGX. Instead of the handful of I/O technologies directly protected by SGX – most of which have to do with DRM rather than user security – the technology proposed in Samuel Weiser and Mario Werner's Arxiv paper, SGXIO, is a “generic” trusted I/O that can be applied to things like keyboards, USB devices, screens and so on. And we're not talking about a merely esoteric technology that might soothe the fears of people running cloud apps on multi-tenant infrastructure. The Weiser/Werner proposal would create an SGX-supported trusted path all the way to a remote user's browser to protect (for example) an online banking session – and provide “attestation mechanisms to enable the bank as well as the user to verify that trusted paths are established and functional.” SGXIO as a way to protect a banking app The shortcoming SGXIO is trying to fix is that SGX's threat model considers everything outside itself a threat (which isn't a bad thing, in context). The usual approach for trusted paths is to use encrypted interfaces. The paper mentions the Protected Audio Video Path (PAVP) – but that's a DRM-specific example, and most I/O devices don't encrypt anything. Hence SGXIO, an attempt to add a generic trusted path to the SGX environment – and with that trusted path reaching to the end user environment, it's an attempt to protect an application from nasties like keyloggers that a miscreant might have installed on a victim's box. The key architectural concepts in SGXIO are: A trusted stack – which contains a security hypervisor, secure I/O drivers, and the trusted boot (TB) enclave; and The virtual machine – hosting an untrusted operating system that runs secure user applications. A user application communicating with the end user: 1. Opens an encrypted channel to the secure I/O driver; 2. This tunnels through the untrusted operating system, and establishes secure communication with the “generic” user I/O device. The hypervisor binds user devices exclusively to I/O; I/O on unprotected devices passes directly through the hypervisor; the trusted path names both the encrypted user-app-to-driver communication; and the exclusive driver-to-device binding; The TB enclave provides assurance of the trusted path setup, by attesting the hypervisor. The paper illustrates this process like this: SGXIO's trusted stack components An implementation wouldn't be seamless: the SGXIO paper devices a fair chunk of copy to application design, enclave programming (fortunately something Intel provides resources for), driver design, and hypervisor choice. Application developers, for example, have to work out a key exchange mechanism (Diffie-Hellman is supported, and SGXIO offers its own lightweight key protocol). For hypervisors, the paper suggests the seL4 microkernel. Originally developed by Australia's NICTA and now handled by the CSIRO Data61 project, seL4 is a mathematically verified software kernel that was published as open source software in 2014. SGXIO will get its first public airing at the CODASPY'17 conference in March, being held in Scottsdale Arizona. ® Sponsored: Customer Identity and Access Management

Wick Hill Feature: Delivering Secure Wi-Fi

Tony Evans from Wick Hill (part of the Nuvias Group) highlights the risks of Wi-Fi and provides some advice for delivering a secure hotspot

The fact that Wi-Fi stands for Wireless Fidelity hints at how long Wi-Fi has been around, but it was only in 1999 that the Wi-Fi Alliance formed as a trade association to hold the Wi-Fi trademark, under which most products are sold.

Today, Wi-Fi is on the top of the list of must-haves for businesses of all types and sizes. People will simply vote with their feet if good and, usually free, Wi-Fi is not available.

But this demand for anytime, anyplace connectivity can mean that some of us are prepared to jump onto Wi-Fi hotspots at cafes, hotel, airports or company guest networks, with only a fleeting consideration of security – a fact that has not gone unnoticed by cyber criminals.

There are over 300,000 videos on YouTube alone explaining how to hack Wi-Fi users with tools easily found online.

Risks from unprotected Wi-Fi:

Wi-Fi Password Cracking
Wireless access points that still use older security protocols such as WEP, make for easy targets because these passwords are notoriously easy to crack. Hotspots that invite us to log in by simply using social network credentials are increasingly popular, as they allow businesses to use demographic information such as age, gender and occupation to target personalised content and advertisements.

Without encryption, Wi-Fi users run the risk of having their private communications intercepted, or packet sniffed, by cyber snoops while on an unprotected network.

Rogue Hotspots
Cyber criminals can set up a spoof access point near your hotspot with a matching SSID that invites unsuspecting customers to log in leaving them susceptible to unnoticed malicious code injection.
In fact, it is possible to mimic a hotspot using cheap, portable hardware that fits into a backpack or could even be attached to a drone.

Planting Malware
There are common hacking toolkits to scan a Wi-Fi network for vulnerabilities, and customers who join an insecure wireless network may unwittingly walk away with unwanted malware.

A common tactic used by hackers is to plant a backdoor on the network, which allows them to return at a later date to steal sensitive information.

Data Theft
Joining an insecure wireless network puts users at risk of losing documents that may contain sensitive information.
In retail environments, for example, attackers focus their efforts on extracting payment details such as credit card numbers, customer identities and mailing addresses.

Inappropriate and Illegal Usage
Businesses offering guest Wi-Fi risk playing host to a wide variety of illegal and potentially harmful communications.

Adult or extremist content can be offensive to neighbouring users, and illegal downloads of protected media leave the businesses susceptible to copyright infringement lawsuits.

Bad Neighbours
As the number of wireless users on the network grows, so does the risk of a pre-infected client entering the network. Mobile attacks, such as Android’s Stagefright, can spread from guest to guest, even if the initial victim is oblivious to the threat.

Best practices
There are established best practices to help secure your Wi-Fi network, alongside a drive, from companies such as WatchGuard, to extend well-proven physical network safeguards to the area of wireless, providing better network visibility to avoid blind spots.

Implementing the latest WPA2 Enterprise (802.1x) security protocol and encryption is a must, while all traffic should, at a minimum, be inspected for viruses and malware, including zero day threats and advanced persistent threats.

Application ID and control will monitor and optionally block certain risky traffic, while web content filtering will prevent unsuspecting users from accidentally clicking a hyperlink that invites exploitation, malware and backdoors to be loaded into your network.

The use of strong passwords, which are changed frequently, should be encouraged, along with regular scanning for rogue Access Points (APs) and whitelisting MAC addresses, when possible.

WatchGuard’s latest cloud-managed wireless access points also have built-in WIPS (Wireless Intrusion Prevention System) technology to defend against unauthorised devices, rogue APs and malicious attacks, with close to zero false positives.

While WIDs (Wireless Intrusion Detection Systems) are common in many Wi-Fi solutions, WIDs require manual intervention to respond to potential threats.

This may be OK for large organisations with IT teams that can manage this, however WIPs is a fully-automated system, which makes it far more attractive to SMEs and organisations such as schools and colleges.

Using patented, Marker Packet wireless detection technology, WatchGuard WIPS differentiates between nearby external access points and rogue access points.
If a rogue access point is detected, all incoming connections to that access point are instantly blocked. WIPS also keeps a record of all clients connecting to the authorised access points, so if a known device attempts to connect to a malicious access point, the connection is instantly blocked. WIPS will also shut down denial-of-service attacks by continuously looking for abnormally high amounts of de-authentication packets.

Wi-Fi as a marketing tool
While Wi-Fi networks have traditionally been viewed as part of the IT infrastructure and the responsibility of the IT department, the latest Wi-Fi systems deliver more than just connectivity, which makes them an attractive proposition for customer services and marketing departments.

For example, the WatchGuard Wi-Fi Cloud provides visibility into marketing data, including insights into footfall and customer demographics and also makes it possible to have direct communication with individual customers in the form of SMS, MMS or social networks.

And with customised splash pages, businesses can personalise the customer Wi-Fi experiences by offering promotional opportunities or surveys and promoting all-important branding.

It is clear that Wi-Fi is here to stay and is becoming much more than simply a way to get online. While the rapid speed of Wi-Fi adoption has led to a disconnect between physical and wireless security, this is now changing and there is no longer any excuse for providing insecure Wi-Fi.

Cryptsetup Vulnerability Grants Root Shell Access on Some Linux Systems

A vulnerability in cryptsetup, a utility used to set up encrypted filesystems on Linux distributions, could allow an attacker to retrieve a root rescue shell on some systems. From there, an attacker could have the ability to copy, modify, or destroy a hard disk, or use the network to exfiltrate data. Cryptsetup, a utility used to setup disk encryption based on the dm-crypt kernel module, is usually deployed in Debian and Ubuntu. Researchers warned late last week that if anyone uses the tool to encrypt system partitions for the operating systems, they’re likely vulnerable. Two researchers, Hector Marco of the University of the West of Scotland and Ismael Ripoll, of the Polytechnic University of Valencia, in Spain, disclosed the vulnerability on Friday at DeepSec, a security conference held at the Imperial Riding School Renaissance Vienna Hotel in Austria. According to the researchers, the script with the vulnerability (CVE-2016-4484) is in the Debian cryptsetup package 2:1.7.2-3 and earlier. Systems that use Dracut, an infrastructure commonly deployed on Fedora in lieu of initramfs – a simple RAM file system directory, are also vulnerable, according to the researchers. The pair say additional Linux distributions outside of Debian and Ubuntu may be vulnerable, they just haven’t tested them yet. The problem stems from the incorrect handling of a password check when a partition is ciphered with LUKS, or Linux Unified Key Setup, a disk encryption specification that’s standard for Linux. Assuming an attacker has access to the computer’s console, when presented with the LUKS password prompt, they could exploit the vulnerability simply by pressing ‘Enter’ over and over again until a shell appears. The researchers say the exploit could take as few as 70 seconds. After a user exceeds the maximum number of three password tries, the boot sequence continues normally. Another script in the utility doesn’t realize this, and drops a BusyBox shell. After carrying out the exploit, the attacker could obtain a root initramfs, or rescue shell. Since the shell can be executed in the initrd, or initial ram disk, environment, it can lead to a handful of scary outcomes, including elevation of privilege, information disclosure, or denial of service. The researchers warn that the vulnerability is especially dangerous in public situations. “This vulnerability is specially serious in environments like libraries, ATMs, airport machines, labs, etc, where the whole boot process is protect (password in BIOS and GRUB) and we only have a keyboard or/and a mouse,” the vulnerability disclosure reads. All an attacker would need in those instances – assuming the system is running Linux – would be access to the keyboard or mouse, Marco and Ripoll say. Tourist information kiosks or airport check in kiosks could be prime targets, the two write. While an attacker would have to have physical access to carry out the attack in most instances, the two warn that in some cloud environments, like those deployed by Ubuntu, the vulnerability could be exploited without physical access. Users can remedy the vulnerability by fixing the cryptroot script file – /scripts/local-top/cryptroot – directly, suspending execution forever, according to the researchers. It’s unclear when a true fix will make its way to the Linux distributions. Neither Debian or Ubuntu immediately returned a request for comment on the vulnerability Tuesday. Marco and Ripoll claim they reported the issue to Debian two weeks ago and while the distribution fixed it, the researchers claim they don’t fully agree with the way it did it. “This is just one of the problems that the boot sequence has in GNU/Linux. It is too permissive on errors, that is. There is the general idea that if the user has physical access to the computer, then the user IS THE OWNER of the computer (this dates from the very beginning of computing). The IoT will dramatically change this assumption,” Marco and Ripoll told Threatpost. “When Windows detects an error… it just shows the blue screen… which is very bad if you are a developer but it is the best solution for 99.9% of the users. Shall the system be developer/hacker friendly, or user secure?”

Spam and phishing in Q3 2016

 Download the full report (PDF) Spam: quarterly highlights Malicious spam Throughout 2016 we have registered a huge amount of spam with malicious attachments; in the third quarter, this figure once again increased significantly.

According to KSN data, in Q3 2016 the number of email antivirus detections totaled 73,066,751. Most malicious attachments contained Trojan downloaders that one way or another loaded ransomware onto the victim’s computer. Number of email antivirus detections, Q1-Q3 2016 The amount of malicious spam reached its peak in September 2016.

According to our estimates, the number of mass mailings containing the Necurs botnet alone amounted to 6.5% of all spam in September.

To recap, this kind of malicious spam downloads the Locky malware to computers. Most emails were neutral in nature. Users were prompted to open malicious attachments imitating bills supposedly sent by a variety of organizations, receipts, tickets, scans of documents, voice messages, notifications from stores, etc.
Some messages contained no text at all.

All this is consistent with recent trends in spam: fraudsters are now less likely to try and impress or intimidate users to make them click a malicious link or open an attachment.
Instead, spammers try to make the email contents look normal, indistinguishable from other personal correspondence.

Cybercriminals appear to believe that a significant proportion of users have mastered the basics of Internet security and can spot a fake threat, so malicious attachments are made to look like everyday mail. Of particular note is the fact that spam coming from the Necurs botnet had a set pattern of technical email headers, while the schemes used by the Locky cryptolocker varied a lot.

For example, the five examples above contain the following four patterns: JavaScript loader in a ZIP archive loads and runs Locky. Locky is loaded using a macro in the .docm file. Archived HTML page with a JavaScript script downloads Locky. Archived HTML page with a JavaScript script downloads the encrypted object Payload.exe, which runs Locky after decryption. Methods and tricks: links in focus IP obfuscation The third quarter saw spammers continue to experiment with obfuscated links.

This well-known method of writing IP addresses in hexadecimal and octal systems was updated by scammers who began to add ‘noise’.

As a result, an IP address in a link may end up looking like this: HTTP://@[::ffff:d598:a862]:80/ Spammers also began to insert non-alphanumeric symbols and slashes in domain/IP addresses, for example: http://0122.0142.0xBABD/ <a href=/@/0x40474B17 URL shortening services Spammers also continued experimenting with URL shortening services, inserting text between slashes.

For example: Sometimes other links were used to add text noise: The use of search queries Some spammers have returned to the old method of hiding the addresses of their sites as search queries.

This allows them to solve two problems: it bypasses black lists and makes the links unique for each email.
In the third quarter, however, spammers went even further and used the Google option “I’m Feeling Lucky”.

This option immediately redirects users to the website that’s displayed first in the list of search results, and it can be activated simply by adding “&btnI=ec” to the end of the link.

Clicking on the link redirects users to the spammer’s site rather than to the page displayed in the Google search results.

The advertising site itself is obviously optimized to appear first in the search results.

There could be lots of similar queries within a single mass mailing. The example above involves yet another trick.

The search query is written in Cyrillic.

The Cyrillic letters are first converted to a decimal format (e.g., “авто” becomes “Авто”), and then the whole query in decimal format, including special symbols, are converted to a hexadecimal URL format. Imitations of popular sites The third quarter saw phishers trying to cheat users by making a link look similar to that of a legitimate site.

This trick is as old as the hills.
In the past, real domain names were distorted very slightly; now, cybercriminals make use of either subdomains imitating real domain names or long domains with hyphens.
So, in phishing attacks on PayPal users we came across the following domain names: Phishing attacks targeting Apple users included the following names: Spammers have also found help from new “descriptive” domain zones, where a fake link can seem more topical and trusted, for example: Testers required Q3 email traffic contained mass mailings asking users to participate in free testing of a product that they could then keep.

The authors of the emails we analyzed were offering popular goods such as expensive brand-name home appliances (coffee machines, robot vacuum cleaners), cleaning products, cosmetics and even food. We also came across a lot of emails offering the chance to test the latest models of electronic devices including the new iPhone that was released at the end of the third quarter.

The headers used in these mass mailings include: “Register to test & keep a new iPhone 7S! Wanted:! IPhone 7S Testers”.

The release of the latest iPhone was met with the usual surge of spam activity dedicated exclusively to Apple products. The largest percentage of spam in the third quarter – 61.25% – was registered in September #KLReport Tweet The people sending out these messages are in no way related to the companies whose products they use as bait. Moreover, they send out their mass mailings from fake email addresses or from empty, newly created domains. The senders promise to deliver the goods for testing by post, and using this pretext they ask for the recipient’s postal and email addresses as well as other personal information.

A small postal charge in is imposed on the user, but even if the goods are delivered, there is no guarantee they will be good quality.

There are lots of posts on the Internet by users saying they never received any goods, even after paying the postage costs.

This has an element of old-fashioned non-virtual fraud: the cybercriminals receive money transfers under the pretext of a postal charges and then disappear. Gift certificates to suit all tastes Spam traffic in Q3 included some interesting mailings using the common theme of fake gift certificates. Recipients were offered the chance to participate in an online survey in return for a certificate worth anything from ten to hundreds of euros or dollars.

They were led to believe that the certificates were valid for large international retail chains, online hypermarkets, grocery stores, popular fast-food chains as well as gas stations. In some cases, the senders of these fraudulent messages said they were carrying out a survey to improve the customer support services of the organizations that were allegedly behind these generous offers, as well as to improve the quality of their products.
In other cases, the message was described as a stroke of luck and that the recipient’s email address was randomly selected for a generous gift as a mark of appreciation for using the brand’s goods or services.

The messages were indeed randomly sent out to email addresses that had been collected by spammers, and did not necessarily belong to customers of the companies named in emails. To confirm receipt of the gift certificate, the user is asked to follow a link in the email which in fact leads to an empty domain with a descriptive name (e.g. “winner of the day”).

Then, via the redirect, the user ends up at a newly created site with a banner designed in the style of the brand that supposedly sent out the mailing.

The user is notified that the number of certificates is limited and that they have only 90 seconds to click on a link, thereby agreeing to receive the gift.

After completing a short survey asking things such as “How often do you use our services?” and “How are you planning to use the certificate?” the user is asked to enter their personal data in a form.

And finally the “lucky winner” is redirected to a secure payment page where they have to enter their bank card details and pay a minor fee (in the case we analyzed the sum was 1 krone). In Q3 2016 Germany (13.21%) remained the country targeted most by malicious mailshots #KLReport Tweet According to online reviews, some potential victims of this type of certificate fraud were asked to call a number to participate in a telephone survey rather than an online survey.

This type of fraudulent scheme is also quite common: the idea is to keep someone on the paid line for as long as possible until they give up on the promised reward. Like the offers to participate in the testing of goods, these themed messages were sent out from fake addresses with empty or newly created domains that had nothing to do with the organizations in whose name the cybercriminals were offering the certificates. Statistics Proportion of spam in email traffic Percentage of spam in global email traffic, Q2 and Q3 2016 The largest percentage of spam in the third quarter – 61.25% – was registered in September.

The average share of spam in global email traffic for Q3 amounted to 59.19%, which was 2 p.p. more than in the previous quarter. Sources of spam by country Sources of spam by country, Q3 2016 In Q3 2016, the contribution from India increased considerably – by 4 p.p. – and became the biggest source of spam with a share of 14.02%.
Vietnam (11.01%, +1 p.p.) remained in second place.

The US fell to third after its share (8.88%) dropped by 1.9 p.p. As in the previous quarter, fourth and fifth were occupied by China (5.02%) and Mexico (4.22%) respectively, followed by Brazil (4.01%), Germany (3.80%) and Russia (3.55%).

Turkey (2.95%) rounded off the TOP 10. Spam email size Breakdown of spam emails by size, Q2 and Q3 2016 Traditionally, the most commonly distributed emails are very small – up to 2 KB (55.78%), although the proportion of these emails has been declining throughout the year, and in Q3 dropped by 16 p.p. compared to the previous quarter. Meanwhile, the proportion of emails sized 10-20 KB increased considerably from 10.66% to 21.19%.

The other categories saw minimal changes. Malicious email attachments Currently, the majority of malicious programs are detected proactively by automatic means, which makes it very difficult to gather statistics on specific malware modifications.
So we have decided to turn to the more informative statistics of the TOP 10 malware families to trigger mail antivirus.
TOP 10 malware families Trojan-Downloader.JS.Agent (9.62%) once again topped the rating of the most popular malware families.

Trojan-Downloader.JS.Cryptoload (2.58%) came second.
Its share increased by 1.34 p.p.

As in the previous quarter, Trojan-Downloader.MSWord.Agent (2.34%) completed the top three. The popular Trojan-Downloader.VBS.Agent family (1.68%) fell to fourth with a 0.48 p.p. decline.
It was followed by Trojan.Win32.Bayrob (0.94%). TOP 10 malware families in Q3 2016 A number of newcomers made it into the bottom half of this TOP 10. Worm.Win32.WBVB (0.60%) in seventh place includes executable files written in Visual Basic 6 (in both P-code and Native modes) that are not recognized as trusted by KSN.

The malware samples of this family are only detected by Mail Anti-Virus.

For this type of verdict File Antivirus only detects objects with names that are likely to mislead users, for example, AdobeFlashPlayer, InstallAdobe, etc. In Q3 2016 India (14.02%) became the biggest source of spam #KLReport Tweet Trojan.JS.Agent (0.54%) came eighth.

A typical representative of this family is a file with .wsf, .html, .js and other extensions.

The malware is used to collect information about the browser, operating system and software whose vulnerabilities can be used.
If the desired vulnerable software is found, the script tries to run a malicious script or an application via a specified link. Yet another newcomer – Trojan-Downloader.MSWord.Cryptoload (0.52%) – occupied ninth place.
It is usually a document with a .doc or .docx extension containing a script that can be executed in MS Word (Visual Basic for Applications).

The script includes procedures for establishing a connection, downloading, saving and running a file – usually a Trojan cryptor. Trojan.Win32.Agent (0,51%), which was seventh in the previous quarter, rounded off the TOP 10 in the third quarter. Countries targeted by malicious mailshots Distribution of email antivirus verdicts by country, Q3 2016 Germany (13.21%) remained the country targeted most by malicious mailshots, although its share continued to decline – by 1.48 p.p. in Q3. Japan (8.76%), whose share increased by 2.36 p.p., moved up to second.

China (8.37%) in third saw its share drop by 5.23 p.p. In Q3 2016, fourth place was occupied by Russia (5.54%); its contribution increased by 1.14 p.p. from the previous quarter.
Italy came fifth with a share of 5.01%.

The US remained in seventh (4.15%).

Austria (2.54%) rounded off this TOP 10. Phishing In Q3 2016, the Anti-Phishing system was triggered 37,515,531 times on the computers of Kaspersky Lab users, which is 5.2 million more than the previous quarter. Overall, 7.75% of unique users of Kaspersky Lab products worldwide were attacked by phishers in Q3 2016. Geography of attacks China (20.21%) remained the country where the largest percentage of users is affected by phishing attacks.
In Q3 2016, the proportion of those attacked increased by 0.01 p.p. Geography of phishing attacks*, Q3 2016 *Number of users on whose computers the Anti-Phishing system was triggered as a percentage of the total number of Kaspersky Lab users in the country The percentage of attacked users in Brazil decreased by 0.4 p.p. and accounted for 18.23%, placing the country second in this rating. UAE added 0.88 p.p. to the previous quarter’s figure and came third with 11.07%.
It is followed by Australia (10.48%, -2.29 p.p.) and Saudi Arabia (10.13%, +1.5 p.p.). TOP 10 countries by percentage of users attacked: China 20.21% Brazil 18.23% United Arab Emirates 11.07% Australia 10.48% Saudi Arabia 10.13% Algeria 10.07% New Zealand 9.7% Macau 9.67% Palestinian Territory 9.59% South Africa 9.28% The share of attacked users in Russia amounted to 7.74% in the third quarter.
It is followed by Canada (7.16%), the US (6.56%) and the UK (6.42%). Organizations under attack Rating the categories of organizations attacked by phishers The rating of attacks by phishers on different categories of organizations is based on detections of Kaspersky Lab’s heuristic anti-phishing component.
It is activated every time a user attempts to open a phishing page while information about it has not yet been included in Kaspersky Lab’s databases.
It does not matter how the user attempts to open the page – by clicking a link in a phishing email or in a message on a social network or, for example, as a result of malware activity.

After the security system is activated, a banner is displayed in the browser warning the user about a potential threat.
In Q3 of 2016, the share of the ‘Financial organizations’ category (banks, payment systems, online stores) accounted for more than half of all registered attacks.

The percentage of the ‘Banks’ category increased by 1.7 p.p. and accounted for 27.13%.

The proportion of ‘Online stores’ (12.21%) and ‘Payment systems’ (11.55%) increased by 2.82 p.p. and 0.31 p.p. respectively. Distribution of organizations affected by phishing attacks by category, Q3 2016 In addition to financial organizations, phishers most often attacked ‘Global Internet portals’ (21.73%), ‘Social networking sites’ (11.54%) and ‘Telephone and Internet service providers’ (4.57%). However, their figures remained almost unchanged from the previous quarter – the change for each category was no more than a single percentage point. Hot topics this quarter Attacks on users of online banking The third quarter saw the proportion of attacked users in the ‘Banks’ category increase significantly – by 1.7 p.p.

The four banks whose clients were attacked most often are all located in Brazil.

For several years in a row this country has ranked among the countries with the highest proportion of users attacked by phishers, and occasionally occupies first place. Naturally, online banking users are priority targets for cybercriminals, since the financial benefits of a successful attack are self-evident. Links to fake banking pages are mostly spread via email. Example of a phishing email sent on behalf of a Brazilian bank.

The link in the email leads to a fake page that imitates the login page to the user’s banking account
‘Porn virus’ for Facebook users At the beginning of the previous quarter, Facebook users were subjected to phishing attacks.

Almost half a year later, the same scheme was used by fraudsters to attack users in Europe.

During the attack, a provocative adult video was used as bait.

To view it, the user was directed to a fake page (a page on the xic.graphics domain was especially popular) imitating the popular YouTube video portal. Example of a user being tagged in a post with the video This extension requested rights to read all the data in the browser, potentially giving the cybercriminals access to passwords, logins, credit card details and other confidential user information.

The extension also distributed more links on Facebook that directed to itself, but which were sent using the victim’s name. Phisher tricks Carrying on from the second quarter, we continue to talk about the popular tricks of Internet fraudsters.

The objectives are simple – to convince their victims that they are using legitimate resources and to bypass security software filters.
It is often the case that the more convincing the page is for the victim, the easier it is to detect with a variety of technologies for combating fraudsters. Nice domains We have already described a trick whereby spammers use genuine-looking links in emails to spread phishing content.

Fraudsters often resort to this technique regardless of how the phishing page is distributed.

They are trying to mislead users, who do actually pay attention to the address in the address bar, but who are not technically savvy enough to see the catch. The main domain of the organization that is being attacked might be represented, for example, by a 13th-level domain: Or might simply be used in combination with another relevant word, e.g., secure: These tricks help deceive potential victims, though they make it much easier to detect phishing attacks using security solutions. Different languages for different victims By using information about the IP address of a potential victim, phishers determine the country in which they are located.
In the example below, they do so by using the service http://www.geoplugin.net/json.gp?ip=. Depending on the country that has been identified, the cybercriminals will display pages with vocabulary in the corresponding language. Examples of files that are used to display a phishing page in a specified language The example below shows 11 different versions of pages for 32 different locations: Example of a script used by phishers to display the relevant page depending on the location of the victim TOP 3 attacked organizations Fraudsters continue to focus most of their attention on the most popular brands, enhancing their chances of a successful phishing attack. More than half of all detections of Kaspersky Lab’s heuristic anti-phishing component are for phishing pages hiding behind the names of fewer than 15 companies. The TOP 3 organizations attacked most frequently by phishers accounted for 21.96% of all phishing links detected in Q3 2016. Organization % of detected phishing links Facebook 8.040955 Yahoo! 7.446908 Amazon.com 6.469801 In Q3 2016, Facebook (8.1%, +0.07 p.p.) topped the ranking of organizations used by fraudsters to hide their attacks. Microsoft, the leader in the previous quarter, dropped out of the TOP 3.
Second place was occupied by Yahoo! (7.45%), whose contribution increased by 0.38 p.p.

Third place went to Amazon, a newcomer to the TOP 3 with 6.47%. Conclusion In the third quarter of 2016, the proportion of spam in email traffic increased by 2 p.p. compared to the previous quarter and accounted for 59.19%.

The largest percentage of spam – 61.25% – was registered in September.
India (14.02%), which was only fourth in the previous quarter, became the biggest source of spam.

The top three sources also included Vietnam (11.01%) and the US (8.88%). The top three countries targeted by malicious mailshots remained unchanged from the previous quarter.

Germany (13.21%) came first again, followed by Japan (8.76%) and China (8.37%). In Q3 2016, Kaspersky Lab products prevented over 37.5 million attempts to enter phishing sites, which is 5.2 million more than the previous quarter.

Financial organizations were the main target, with banks the worst affected, accounting for 27.13% of all registered attacks.

The most attractive phishing targets in Q3 2016 were clients of four banks located in Brazil.

Android patches fix Drammer RAM attack, but not Dirty Cow exploit

Google released a new monthly batch of security patches for Android, fixing a dozen critical vulnerabilities that could allow attackers to compromise devices. One of the mitigated issues is a bit-flipping attack against memory chips that could lead to privilege escalation, but a more widespread rooting vulnerability in the Linux kernel remains unpatched. While Google releases firmware updates for its Nexus and Pixel devices on the first Monday of every month, the security patches are shared with third-party device manufacturers one month in advance and are also contributed later to the Android Open Source Project to benefit the entire ecosystem. Like it has done in recent months, Google has split this month’s security fixes into several “security patch levels,” to make it easier for manufacturers to deploy only fixes that apply to specific devices.

The security patch level is a date string displayed in Android’s settings under “About phone” and indicates that the firmware contains all Android security patches up to that date. The new 2016-11-01 patch level contains fixes for flaws in Android’s own components.
It addresses two critical vulnerabilities, 16 high-risk flaws and 10 medium-risk ones. One of the critical flaws is located in the Mediaserver component, which has been a major source of serious Android vulnerabilities over the past year.

The flaw can be exploited by tricking users into downloading or opening a specially crafted media file. The second critical flaw is located in the libzipfile library and could enable malicious applications to execute code within the context of a privileged process.

This can lead to a full device compromise that requires reflashing the operating system to fix. The second patch level is 2016-11-05 and primarily includes fixes for vulnerabilities in kernel drivers for various hardware components.

This level covers 21 critical vulnerabilities, 23 high-risk ones and 10 with a moderate impact. The critical flaws are located in the kernel file system, SCSI driver, media driver, USB driver, ION subsystem, networking subsystem and sound subsystem, as well as in the Nvidia GPU driver and Qualcomm’s crypto driver, bootloader and other components. One of the patches for the ION memory allocator is intended to mitigate a physical attack against DRAM (dynamic random-access memory) chips that could be exploited by applications to gain root access on a device.

The attack is known as Drammer and was devised by researchers from the Vrije Universiteit Amsterdam in the Netherlands, the Graz University of Technology in Austria, and the University of California in Santa Barbara. The third patch level is 2016-11-06 and covers a privilege escalation vulnerability in the memory subsystem of the Linux kernel that was disclosed a few weeks ago.

The flaw, which the security community dubbed Dirty COW (copy-on-write) has existed in the Linux kernel for the past nine years and is already being exploited in the wild. Google has not patched this vulnerability in its Nexus and Pixel devices yet and will probably do it next month. However, device manufacturers can address the flaw by importing the upstream fix that was included in the Linux kernels versions 3.10 and 3.18.

The flaw was disclosed after this month’s patch levels had already been defined, which is why Google refers to the 2016-11-06 patch level as “supplemental.”

IT threat evolution Q3 2016. Statistics

 Download the full report (PDF) Statistics All the statistics used in this report were obtained using Kaspersky Security Network (KSN), a distributed antivirus network that works with various anti-malware protection components. The data was collected from KSN users who agreed to provide it. Millions of Kaspersky Lab product users from 213 countries and territories worldwide participate in this global exchange of information about malicious activity. Q3 figures According to KSN data, Kaspersky Lab solutions detected and repelled 171,802,109 malicious attacks from online resources located in 190 countries all over the world. 45,169,524 unique URLs were recognized as malicious by web antivirus components. Kaspersky Lab’s web antivirus detected 12,657,673 unique malicious objects: scripts, exploits, executable files, etc. Attempted infections by malware that aims to steal money via online access to bank accounts were registered on 1,198,264 user computers. Crypto ransomware attacks were blocked on 821,865 computers of unique users. Kaspersky Lab’s file antivirus detected a total of 116,469,744 unique malicious and potentially unwanted objects. Kaspersky Lab mobile security products detected: 1,520,931 malicious installation packages; 30,167 mobile banker Trojans (installation packages); 37,150 mobile ransomware Trojans (installation packages). Mobile threats Q3 events Pokémon GO: popular with users and hackers One of the most significant events of the third quarter was the release of Pokémon GO. Of course, cybercriminals could not ignore such a popular new product and tried to exploit the game for their own purposes. This was primarily done by adding malicious code to the original app and spreading malicious versions via third-party stores. This method was used, for example, to spread Trojan-Banker.AndroidOS.Tordow, which exploits vulnerabilities in the system to obtain root access to a device. With root access, this Trojan protects itself from being deleted, and it can also steal saved passwords from browsers. But perhaps the most notable case of Pokémon GO’s popularity being used to infect mobile devices involved fraudsters publishing a guide for the game in the official Google Play store. The app turned out to be an advertising Trojan capable of gaining root access to a device by exploiting vulnerabilities in the system. We later came across two more modifications of this Trojan, which were added to Google Play under the guise of different apps. According to Google Play data, one of them, imitating an equalizer, was installed between 100,000 and 500,000 times. Trojan.AndroidOS.Ztorg.ad in the official Google Play store Interestingly, one of the methods used by the cybercriminals to promote the Trojan was a company that pays users for the installation of advertising apps. Screenshot of the app that prompts the user to install the Trojan for 5 cents According to this company’s rules, it doesn’t work with users whose devices have root access. The users may be looking to earn some money, but they end up with an infected device and don’t actually receive any money, because after infection the device gains root access. Ad with a Trojan The most popular mobile Trojan in the third quarter of 2016 was Trojan-Banker.AndroidOS.Svpeng.q. During the quarter, the number of users attacked by it grew almost eightfold. Over 97% of users attacked by Svpeng were located in Russia. The attackers managed to make the Trojan so popular by advertising it via Google AdSense – one of the most popular advertising networks on the Russian Internet. Many popular sites use it to display targeted advertising. Anyone can pay to register their ad on the network, and that was exactly what the attackers did. Along with the advert, however, they added the AdSense Trojan. When a user visited the page with the advert, Svpeng was downloaded to their device. Bypassing protection mechanisms in Android 6 In our report for the second quarter of 2016 we mentioned the Trojan-Banker.AndroidOS.Asacub family that can bypass several system controls. Of special note this quarter is the Trojan-Banker.AndroidOS.Gugi family that has learned to bypass the security mechanisms introduced in Android 6 by tricking the user. The Trojan first requests rights to overlay other applications, and then uses those rights to trick the user into giving it privileges to work with text messages and to make calls. Trojan ransomware in the Google Play store In the third quarter, we registered the propagation of Trojan-Ransom.AndroidOS.Pletor.d, a mobile ransomware program, via Google Play. The Trojan imitated an app for servicing devices, including deleting unnecessary data, speeding up device performance and even antivirus protection. Trojan-Ransom.AndroidOS.Pletor.d in Google Play The Trojan checks which country the device is located in, and if it is not Russia or Ukraine, it requests administrator rights and calls the command server. Earlier versions of this Trojan encrypted user data, but this modification doesn’t possess such functionality. Instead, the Trojan blocks operation of the device by opening a window that covers all other open windows and demanding a ransom to unblock it. Mobile threat statistics In Q3 2016, Kaspersky Lab detected 1,520,931 malicious installation packages, which is 2.3 times fewer than in the previous quarter. Number of detected malicious installation packages (Q4 2015 – Q1 2016) Distribution of mobile malware by type Distribution of new mobile malware by type (Q2 2016 and Q3 2016) In Q3 2016, RiskTool software, or legitimate applications that are potentially dangerous to users, topped the rating of malicious objects detected for mobile devices. Their share continued to grow from 45.1% in Q2 to 55.8% this quarter. Due to the large number of RiskTool programs and the considerable increase in their overall share of the total flow of detected objects, the proportion of almost all other types of malicious programs decreased, even where the actual number of detected programs increased compared to the previous quarter. The most affected was Trojan-Ransom – its share decreased from 5.72% to 2.37%. This was caused by a decline in activity by the Trojan-Ransom.AndroidOS.Fusob family (covered in more detail below). At the same time, we registered a slight growth in the share of Trojan-Bankers – from 1.88% to 1.98%. TOP 20 mobile malware programs Please note that this rating of malicious programs does not include potentially dangerous or unwanted programs such as RiskTool or adware. Name % of attacked users* 1 DangerousObject.Multi.Generic 78,46 2 Trojan-Banker.AndroidOS.Svpeng.q 11,45 3 Trojan.AndroidOS.Ztorg.t 8,03 4 Backdoor.AndroidOS.Ztorg.c 7,24 5 Backdoor.AndroidOS.Ztorg.a 6,55 6 Trojan-Dropper.AndroidOS.Agent.dm 4,91 7 Trojan.AndroidOS.Hiddad.v 4,55 8 Trojan.AndroidOS.Agent.gm 4,25 9 Trojan-Dropper.AndroidOS.Agent.cv 3,67 10 Trojan.AndroidOS.Ztorg.aa 3,61 11 Trojan-Banker.AndroidOS.Svpeng.r 3,44 12 Trojan.AndroidOS.Ztorg.pac 3,31 13 Trojan.AndroidOS.Iop.c 3,27 14 Trojan.AndroidOS.Muetan.b 3,17 15 Trojan.AndroidOS.Vdloader.a 3,14 16 Trojan-Dropper.AndroidOS.Triada.s 2,80 17 Trojan.AndroidOS.Muetan.a 2,77 18 Trojan.AndroidOS.Triada.pac 2,75 19 Trojan-Dropper.AndroidOS.Triada.d 2,73 20 Trojan.AndroidOS.Agent.eb 2,63 * Percentage of unique users attacked by the malware in question, relative to all users of Kaspersky Lab’s mobile security product that were attacked. First place is occupied by DangerousObject.Multi.Generic (78.46%), the verdict used for malicious programs detected using cloud technologies. Cloud technologies work when the antivirus database contains neither the signatures nor heuristics to detect a malicious program, but the cloud of the antivirus company already contains information about the object. This is basically how the very latest malware is detected. In Q3 2016, 17 Trojans that use advertising as their main means of monetization (highlighted in blue in the table) made it into the TOP 20. Their goal is to deliver as many adverts as possible to the user, employing various methods, including the installation of new adware. These Trojans may use superuser privileges to conceal themselves in the system application folder, from which it will be very difficult to delete them. In Q3 2016, attempted infections by financial #malware were registered at 1.2m users’ computers #KLreport #banking Tweet With root access on the device, Trojans can do many different things without the user being aware, such as installing apps from Google Play, including paid apps. It’s worth noting that the Trojans from the Ztorg family, which occupied four places in the TOP 20, are often distributed via the official Google Play store. Since the end of 2015, we have registered more than 10 such cases (including a fake guide for Pokemon GO). Several times the Trojan notched up over 100,000 installations, and on one occasion it was installed more than 500,000 times. Trojan.AndroidOS.Ztorg.ad masquerading as a guide for Pokemon GO in Google Play The ranking also included two representatives of the Trojan-Banker.AndroidOS.Svpeng mobile banker family. As we mentioned above, Svpeng.q became the most popular malware in the third quarter of 2016. This was down to the Trojan being distributed via the AdSense advertising network, which is used by a large number of sites on the Russian segment of the Internet. The geography of mobile threats The geography of attempted mobile malware infections in Q3 2016 (percentage of all users attacked) TOP 10 countries attacked by mobile malware (ranked by percentage of users attacked) Country* % of users attacked ** 1 Bangladesh 35,57 2 Nepal 31.54 3 Iran 31.38 4 China 26.95 5 Pakistan 26.83 6 Indonesia 26.33 7 India 24,35 8 Nigeria 22.88 9 Algeria 21,82 10 The Philippines 21.67 * We eliminated countries from this rating where the number of users of Kaspersky Lab’s mobile security product is relatively low (under 10,000).** Percentage of unique users attacked in each country relative to all users of Kaspersky Lab’s mobile security product in the country. Bangladesh topped the rating, with almost 36% of users there encountering a mobile threat at least once during the quarter. China, which came first in this rating two quarters in a row, dropped to fourth place. The most popular mobile malware in all the countries of this rating (except China) was the same – advertising Trojans that mostly belonged to the Ztorg, Iop, Hiddad and Triada families. A significant proportion of attacks in China also involved advertising Trojans, but the majority of users there encountered Trojans from the Backdoor.AndroidOS.GinMaster and Backdoor.AndroidOS.Fakengry families. Russia (12.1%) came 24th in this rating, France (6.7%) 52nd, the US (5.3%) 63rd, Italy (5.1%) 65th, Germany (4.9%) 68th, and the United Kingdom (4.7%) 71st. The situation in Germany and Italy has improved significantly: in the previous quarter, 8.5% and 6.2% of users in those countries respectively were attacked. This was due to a decline in activity by the Fusob family of mobile ransomware. The safest countries were Austria (3.3%), Croatia (3.1%) and Japan (1.7%). Mobile banking Trojans Over the reporting period, we detected 30,167 installation packages for mobile banking Trojans, which is 1.1 times as many as in Q2. Number of installation packages for mobile banking Trojans detected by Kaspersky Lab solutions(Q4 2015 – Q3 2016) Trojan-Banker.AndroidOS.Svpeng became the most popular mobile banking Trojan in Q3 due to its active distribution via the advertising network AdSense. More than half the users that encountered mobile banking Trojans in the third quarter faced Trojan-Banker.AndroidOS.Svpeng.q. It was constantly increasing the rate at which it spread – in September the number of users attacked by the Trojan was almost eight times greater than in June. The number of unique users attacked by the Trojan-Banker.AndroidOS.Svpeng banking Trojan family(June-September 2016) Over 97% of attacked users were in Russia. This family of mobile banking Trojans uses phishing windows to steal credit card data and logins and passwords from online banking accounts. In addition, fraudsters steal money via SMS services, including mobile banking. Geography of mobile banking threats in Q3 2016 (percentage of all users attacked) TOP 10 countries attacked by mobile banker Trojans (ranked by percentage of users attacked) Country* % of users attacked** 1 Russia 3.12 2 Australia 1.42 3 Ukraine 0.95 4 Uzbekistan 0.60 5 Tajikistan 0.56 6 Kazakhstan 0.51 7 China 0.49 8 Latvia 0.47 9 Russia 0.41 10 Belarus 0.37 * We eliminated countries from this rating where the number of users of Kaspersky Lab’s mobile security product is relatively low (under 10,000).** Percentage of unique users in each country attacked by mobile banker Trojans, relative to all users of Kaspersky Lab’s mobile security product in the country. In Q3 2016, first place was occupied by Russia (3.12%) where the proportion of users that encountered mobile banker Trojans almost doubled from the previous quarter. In second place again was Australia (1.42%), where the Trojan-Banker.AndroidOS.Acecard and Trojan-Banker.AndroidOS.Marcher families were the most popular threats. The most widely distributed mobile banking Trojans in Q3 were representatives of the Svpeng, Faketoken, Regon, Asacub, Gugi and Grapereh families. In particular, the third quarter saw the Trojan-Banker.AndroidOS.Gugi family learn how to bypass protection mechanisms in Android by tricking users. Mobile Ransomware In Q3 2016, we detected 37,150 mobile Trojan-Ransomware installation packages. Number of mobile Trojan-Ransomware installation packages detected by Kaspersky Lab(Q4 2015 – Q3 2016) The sharp rise in the number of mobile Trojan-Ransomware installation packages in Q1 and Q2 of 2016 was caused by the active proliferation of the Trojan-Ransom.AndroidOS.Fusob family of Trojans. In the first quarter of 2016, this family accounted for 96% of users attacked by mobile ransomware; in Q2 it accounted for 85%. Its share in Q3 was 73%. Number of users attacked by the Trojan-Ransom.AndroidOS.Fusob family, January-September 2016 The highest number of users attacked by the mobile Trojan-Ransomware family was registered in March 2016. Since then the amount of attacked users has been decreasing, especially in Germany. Despite this, Trojan-Ransom.AndroidOS.Fusob.h remained the most popular mobile Trojan-Ransomware in the third quarter, accounting for nearly 53% of users attacked by mobile ransomware. Once run, the Trojan requests administrator privileges, collects information about the device, including GPS coordinates and call history, and downloads the data to a malicious server. After that, it may receive a command to block the device. Geography of mobile Trojan-Ransomware in Q3 2016 (percentage of all users attacked) TOP 10 countries attacked by mobile Trojan-Ransomware (ranked by percentage of users attacked) Country* % of users attacked ** 1 Canada 0.95 2 USA 0.94 3 Kazakhstan 0.71 4 Germany 0.63 5 UK 0.61 6 Mexico 0.58 7 Australia 0.57 8 Spain 0,54 9 Italy 0.53 10 Switzerland 0.51 * We eliminated countries from this ranking where the number of users of Kaspersky Lab’s mobile security product is relatively low (under 10,000).** Percentage of unique users in each country attacked by mobile Trojan-Ransomware, relative to all users of Kaspersky Lab’s mobile security product in the country. In all the TOP 10 countries apart from Kazakhstan, the most popular Trojan-Ransom family was Fusob. In the US, the Trojan-Ransom.AndroidOS.Svpeng family was also popular. This Trojan family emerged in 2014 as a modification of the Trojan-Banker.AndroidOS.Svpeng family. These Trojans demand a ransom of $100-$500 from victims to unblock their devices. In Q3 2016, #crypto #ransomware attacks were blocked on 821,865 unique computers #KLreport Tweet In Kazakhstan, the main threat to users originated from representatives of the Small mobile Trojan-Ransom family. This is a fairly simple ransomware program that blocks the operation of a device by overlaying all the windows with its own and demanding $10 to remove it. Vulnerable apps exploited by cybercriminals In Q3 2016, the Neutrino exploit kit departed the cybercriminal market, following in the wake of Angler and Nuclear which also left the market in the previous quarter. RIG and Magnitude remain active. RIG was especially prominent – it has quickly filled the vacant niche on the exploit kit market. This is the overall picture for the use of exploits this quarter: Distribution of exploits used in attacks by the type of application attacked, Q3 2016 Exploits for different browsers and their components (45%) once again topped the rating, although their share decreased by 3 percentage points. They are followed by exploits for Android OS vulnerabilities (19%), whose share fell 5 p.p. in the third quarter. Exploits kits for Microsoft Office rounded off the top three. Their contribution actually saw an increase from 14% to 16% in Q3. Exploits for Adobe Flash Player remained popular. In fact, their share more than doubled from 6% to 13%. This was caused by the aforementioned RIG exploit kit: its use in several campaigns saw the share of SWF exploits increase dramatically. Online threats (Web-based attacks) The statistics in this section were derived from web antivirus components that protect users from attempts to download malicious objects from a malicious/infected website. Malicious websites are created deliberately by malicious users; infected sites include those with user-contributed content (such as forums), as well as compromised legitimate resources. In the third quarter of 2016, Kaspersky Lab’s web antivirus detected 12,657,673 unique malicious objects (scripts, exploits, executable files, etc.) and 45,169,524 unique URLs were recognized as malicious by web antivirus components. Kaspersky Lab solutions detected and repelled 171,802,109 malicious attacks from online resources located in 190 countries all over the world. Online threats in the banking sector These statistics are based on detection verdicts of Kaspersky Lab products, received from users of Kaspersky Lab products who have consented to provide their statistical data. Kaspersky Lab solutions blocked attempts to launch malware capable of stealing money via online banking on 1,198,264 computers in Q3 2016. The number of users attacked by financial malware increased by 5.8% from the previous quarter (1,132,031). The third quarter is traditionally holiday season for many users of online banking services in Europe, which means the number of online payments made by these users increases during this period. This inevitably sees an increase in financial risks. Number of users attacked by financial malware, Q3 2016 In Q3, the activity of financial threats grew month on month. Geography of attacks To evaluate and compare the risk of being infected by banking Trojans worldwide, we calculate the percentage of Kaspersky Lab product users in the country who encountered this type of threat during the reporting period, relative to all users of our products in that country. Geography of banking malware attacks in Q3 2016 (percentage of attacked users) TOP 10 countries by percentage of attacked users Country* % of attacked users** 1 Russia 4.20 2 Sri Lanka 3.48 3 Brazil 2.86 4 Turkey 2.77 5 Cambodia 2.59 6 Ukraine 1.90 7 Venezuela 1.90 8 Vietnam 1.86 9 Argentina 1.86 10 Uzbekistan 1.77 These statistics are based on detection verdicts returned by the antivirus module, received from users of Kaspersky Lab products who have consented to provide their statistical data.* We excluded those countries in which the number of Kaspersky Lab product users is relatively small (under 10,000).** Unique users whose computers have been targeted by banking Trojan attacks as a percentage of all unique users of Kaspersky Lab products in the country. In the third quarter of 2016, Russia had the highest proportion of users attacked by banking Trojans. Representatives of the Trojan-Banker ZeuS (Zbot) family, which leads the way in terms of the number of attacked users worldwide, were especially active in Russia. This is unsurprising since Russian cybercriminals are allegedly behind the development of this malware. They know the specifics of Russia’s online banking systems as well as the mentality of Russian users and take them into consideration when developing their malware. In Russia, the Gozi banking Trojan continues to proliferate. It displayed a burst of activity in the previous quarter after its developers joined forces with the creators of the Nymaim Trojan. Russia also topped the TOP 10 countries with the highest proportion of users attacked by mobile bankers. Sri Lanka, a favorite destination with tourists, was a newcomer to the rating, going straight in at second. Financial threats were encountered by 3.48% of users in the country. Among them are likely to be foreigners who arrived in the country on holiday and used online banking services to make payments. The most active representatives of banking malware in the region were those from the Fsysna banker family. This family has previously been noted for attacks targeting customers of Latin American banks. In Q3 2016, @kaspersky #mobile security products detected 1.5m malicious installation packages #KLreport Tweet Brazil rounds off the top three for the second quarter in a row. In Q2, we forecast a surge of financial threat activity in Latin America and specifically in Brazil because of this summer’s Olympic Games. However, the increase in the proportion of users attacked in Brazil was negligible: in the third quarter, 2.86% of users in Brazil encountered financial threats compared to 2.63% in Q2. At the same time, users in Argentina were subjected to a surge in malicious attacks, and as a result, the country ranked ninth. The holiday season affected almost all countries in the TOP 10. In Russia, Ukraine and Uzbekistan, people traditionally have vacations at this time of the year, while other countries (Sri Lanka, Brazil, Turkey, Cambodia, etc.) are considered popular tourist destinations. Tourists tend to be active users of online banking systems, which in turn attracts cybercriminals and their banking malware. The share of banking Trojan victims in Italy was 0.60%, in Spain it was 0.61%, while in Germany and the UAE the figures were 1.21% and 1.14% respectively. The TOP 10 banking malware families The table below shows the TOP 10 malware families used in Q3 2016 to attack online banking users (as a percentage of users attacked): Name* % of attacked users** 1 Trojan-Spy.Win32.Zbot 34.58 2 Trojan.Win32.Qhost/Trojan.BAT.Qhost 9.48 3 Trojan.Win32.Fsysna 9.467 4 Trojan-Banker.Win32.Gozi 8.98 5 Trojan.Win32.Nymaim 8.32 6 Trojan-Banker.Win32.Shiotob 5.29 7 Trojan-Banker.Win32.ChePro 3.77 8 Trojan-Banker.Win32.BestaFera 3.31 9 Trojan-Banker.Win32.Banbra 2.79 10 Trojan.Win32.Neurevt 1.79 * The detection verdicts of Kaspersky Lab products, received from users of Kaspersky Lab products who have consented to provide their statistical data.** Unique users whose computers have been targeted by the malware in question as a percentage of all users attacked by financial malware. The undisputed leader of the rating is Trojan-Spy.Win32.Zbot. Its source codes have been publicly available since a leak and are now widely exploited as an easy-to-use tool for stealing user payment data. Unsurprisingly, this malware consistently tops this rating – cybercriminals regularly enhance the family with new modifications compiled on the basis of the source code and containing minor differences from the original. The family of Qhost Trojans (verdicts Trojan.Win32.Qhost and Trojan.BAT.Qhost) came second. The functionality of this family’s malicious programs is relatively simple: the Trojan modifies the content of the Host file (a special text file that contains a database of domain names that are used when transmitting to the network addresses of nodes) and as soon as specific resources are visited, the Trojan’s malicious components are loaded to an infected workstation and used to steal payment information. The Trojan adds a number of records to the Host file preventing the user’s browser from connecting to web-based apps and resources of popular antivirus vendors. The Q3 rating also includes a new malware representative that has already demonstrated its capabilities in Sri Lanka – the Trojan.Win32.Fsysna family of banking Trojans. Members of this family, in addition to stealing payment data from infected workstations, are also used by cybercriminals to distribute spam. The Trojan uses an infected machine to redirect spam messages from the command center to a mail server. Some representatives of this family also possess Trojan cryptor functionality. Fsysna is kind of a ‘Swiss army knife’ used by cybercriminals to steal money. Q3 2016 saw a decline in the activity of the notorious financial threat Trojan-Spy.Win32.Lurk: the number of users attacked by this malware fell by 7.1%. Lurk was not included in the TOP 10 banking malware families, but it still poses a threat to users of online banking systems. The cybercriminal group behind this financial threat has been arrested (something we wrote about in a separate article), so we expect to see a further decrease in activity by this banking Trojan next quarter. Ransomware Trojans Cryptors are currently one of the biggest threats to users and companies. These malicious programs are becoming more and more popular in the cybercriminal world because they are capable of generating large profits for their owners. A total of 21 new cryptor families and 32,091 new modifications were detected in Q3. We also added several existing cryptor families to our virus collection. The number of new cryptor families added to our virus collection is slightly less than in the second quarter (25), but the number of newly created modifications increased 3.5 times compared to the previous quarter. The number of newly created cryptor modifications, Q1 – Q3 2016 Malware writers are constantly trying to improve their creations. New ways to infect computers are always being sought, especially for attacks on companies, which cybercriminals see as far more profitable than attacks on standard users. Remote launching of cryptors by cybercriminals We are increasingly seeing incidents where cybercriminals crack passwords to gain remote access to a victim’s system (usually an organization) and infect a compromised machine with Trojan ransomware. Examples of this in Q3 were Dcryptor and Xpan. Dcryptor/Mamba Trojan-Ransom.Win32.Dcryptor is known on the Internet under the pseudonym ‘Mamba’. Infection is carried out manually. The fraudsters brute-force the passwords for remote access to the victim machine and run the Trojan, passing on the password for encryption as a command line argument. During infection, the Trojan uses the legitimate DiskCryptor utility. As a result, it’s not just individual files on network drives that are infected but entire hard drive sectors on the local machine. System boot is blocked: once the computer is started, a message appears on the screen demanding a ransom and displaying an email address for communicating with the attackers. This Trojan reminds us of the notorious Petya/Mischa Trojan and continues the growing trend of cybercriminals looking for new ways to block access to data. Xpan/TeamXRat ransomware Trojan-Ransom.Win32.Xpan is yet another example of ransomware that is launched after attackers remotely penetrate a system. This Trojan is distributed by Brazilian cybercriminals. They brute-force the RDP password (the standard protocol for remote access to Windows computers) and infect the compromised system using the Xpan Trojan that encrypts files and displays a ransom demand. Ransomware in scripting languages Another trend that has attracted our attention is the growing number of cryptors written in scripting languages. In the third quarter of 2016, we came across several new families written in Python: HolyCrypt (Trojan-Ransom.Python.Holy) CryPy (Trojan-Ransom.Python.Kpyna) Trojan-Ransom.Python.Agent Another example that emerged in June was Stampado (Trojan-Ransom.Win32.Stampa) written in AutoIt, the automation language. The number of users attacked by ransomware In Q3 2016, 821,865 unique KSN users were attacked by cryptors – that is 2.6 times more than the previous quarter. Number of unique users attacked by Trojan-Ransom cryptor malware (Q3 2016) The largest contribution was made by representatives of the Trojan-Downloader.JS.Cryptoload family. These Trojan downloaders, written in JavaScript, were designed to download and install representatives of different cryptor families in the system. Geography of Trojan-Ransomattacks in Q3 2016 (percentage of attacked users) Top 10 countries attacked by cryptors Country* % of users attacked by cryptors** 1 Japan 4.83 2 Croatia 3.71 3 Korea 3.36 4 Tunisia 3.22 5 Bulgaria 3.20 6 Hong Kong 3.14 7 Taiwan 3.03 8 Argentina 2.65 9 Maldives 2.63 10 Australia 2.56 * We excluded those countries where the number of Kaspersky Lab product users is relatively small (under 10,000).** Unique users whose computers have been targeted by ransomware as a percentage of all unique users of Kaspersky Lab products in the country. As in the previous quarter, Japan topped this rating. Newcomers to this Top 10 were Tunisia, Hong Kong, Argentina, and Australia, with Italy, Djibouti, Luxembourg, and the Netherlands all making way. Top 10 most widespread cryptor families Name Verdict* % of attacked users** 1 CTB-Locker Trojan-Ransom.Win32.Onion/ Trojan-Ransom.NSIS.Onion 28.34 2 Locky Trojan-Ransom.Win32.Locky 9.60 3 CryptXXX Trojan-Ransom.Win32.CryptXXX 8.95 4 TeslaCrypt Trojan-Ransom.Win32.Bitman 1.44 5 Shade Trojan-Ransom.Win32.Shade 1.10 6 Cryakl Trojan-Ransom.Win32.Cryakl 0.82 7 Cryrar/ACCDFISA Trojan-Ransom.Win32.Cryrar 0.73 8 Cerber Trojan-Ransom.Win32.Zerber 0.59 9 CryptoWall Trojan-Ransom.Win32.Cryptodef 0.58 10 Crysis Trojan-Ransom.Win32.Crusis 0.51 * These statistics are based on detection verdicts received from users of Kaspersky Lab products who have consented to provide their statistical data.** Unique users whose computers have been targeted by a specific Trojan-Ransom family as a percentage of all users of Kaspersky Lab products attacked by Trojan-Ransom malware. CTB-Locker once again occupied first place in the Q3. The top three also included the now infamous Locky and CryptXXX. Despite the fact that the owners of TeslaCrypt disabled their servers and posted a master key to decrypt files back in May 2016, it continues to make it into our rating (although its contribution dropped by 5.8 times in Q3) Crysis Crysis (verdict Trojan-Ransom.Win32.Crusis) was a newcomer to the TOP 10 in Q3. This Trojan was first detected in February 2016 and since then has undergone several code modifications. Interestingly, the list of email addresses used for ransom demands by the distributors of Crysis partly matches the list associated with the Cryakl and Aura Trojans. Analysis of the executable files from these families, however, shows that they do not share the same code. It appears that these malicious programs are spread via a partner scheme, and because some distributors are distributing several different Trojans simultaneously they are using the same email address to communicate their ransom demands to the victims. Polyglot/MarsJoke This Trojan appeared in August 2016 (we recently published a detailed analysis of Polyglot/ MarsJoke). It is not included in the TOP 10, but it does have one interesting feature: the authors have tried to imitate the well-known CTB-Locker, which tops the rating for the second quarter in a row. Both the external and internal design of this piece of malware is very similar to the “original”, but the cybercriminals made a mistake that allows files to be decrypted without paying a ransom. Top 10 countries where online resources are seeded with malware The following statistics are based on the physical location of the online resources used in attacks and blocked by our antivirus components (web pages containing redirects to exploits, sites containing exploits and other malware, botnet command centers, etc.). Any unique host could be the source of one or more web attacks. In order to determine the geographical source of web-based attacks, domain names are matched against their actual domain IP addresses, and then the geographical location of a specific IP address (GEOIP) is established. In Q3 2016, Kaspersky Lab solutions blocked 171,802,109 attacks launched from web resources located in 190 countries around the world. 45,169,524 unique URLs were recognized as malicious by web antivirus components. 83% of notifications about blocked web attacks were triggered by attacks coming from web resources located in 10 countries. Distribution of web attack sources by country, Q3 2016 The US (33.51%) remained top of this rating in Q3. Russia (9%) dropped from second to fourth, while Germany came second with a share of 10.5%. Canada left the Top 10, with Cyprus a newcomer in ninth place (1.24%). Countries where users faced the greatest risk of online infection In order to assess the risk of online infection faced by users in different countries, we calculated the percentage of Kaspersky Lab users in each country who encountered detection verdicts on their machines during the quarter. The resulting data provides an indication of the aggressiveness of the environment in which computers work in different countries.

Local threats Local infection statistics for user computers are a very important indicator: they reflect threats that have penetrated computer systems by infecting files or removable media, or initially got on the computer in an encrypted format (for example, programs integrated in complex installers, encrypted files, etc.). Data in this section is based on analyzing statistics produced by antivirus scans of files on the hard drive at the moment they were created or accessed, and the results of scanning removable storage media.

Physical RAM attack can root Android and possibly other devices

Researchers have devised a new way to compromise Android devices without exploiting any software vulnerabilities and instead taking advantage of a physical design weakness in RAM chips.

The attack technique could also affect other ARM and x86-based devices and computers. The attack stems from the push over the past decade to pack more DRAM (dynamic random-access memory) capacity onto increasingly smaller chips, which can lead to memory cells on adjacent rows leaking electric charges to one another under certain conditions. For example, repeated and rapid accessing of physical memory locations -- an action now dubbed "hammering" -- can cause the bit values from adjacent locations to flip from 0 to 1 or the other way around. While such electrical interference has been known for a while and has been studied by vendors from a reliability standpoint -- because memory corruption can lead to system crashes -- researchers have shown that it can also have serious security implications when triggered in a controlled manner. In March 2015, researchers from Google's Project Zero presented two privilege escalation exploits based on this memory "row hammer" effect on the x86-64 CPU architecture. One of the exploits allowed code to escape the Google Chrome sandbox and be executed directly on the OS and the other gained kernel-level privileges on a Linux machine. Since then, other researchers have further investigated the problem and have shown that it could be exploited from websites through JavaScript or could affect virtualized servers running in cloud environments. However, there have been doubts about whether the technique would also work on the significantly different ARM architecture used in smartphones and other mobile devices. But now, a team of researchers from the VUSec Group at Vrije Universiteit Amsterdam in the Netherlands, the Graz University of Technology in Austria, and the University of California in Santa Barbara has demonstrated not only are Rowhammer attacks possible on ARM, but they're even easier to pull off than on x86. The researchers dubbed their new attack Drammer, which stands for deterministic Rowhammer, and plan to present it Wednesday at the 23rd ACM Conference on Computer and Communications Security in Vienna.

The attack builds upon previous Rowhammer techniques devised and demonstrated in the past. The VUSec researchers have created a malicious Android application that doesn't require any permissions and gains root privileges when it is executed by using undetectable memory bit flipping. The researchers tested 27 Android devices from different manufacturers, 21 using ARMv7 (32-bit) and six using ARMv8 (64-bit) architectures.

They managed to flip bits on 17 of the ARMv7 devices and one of the ARMv8 devices, indicating they are vulnerable to the attack. Furthermore, Drammer can be combined with other Android vulnerabilities such as Stagefright or BAndroid to build remote attacks that don't require users to manually download the malicious app. Google is aware of this type of attack. "After researchers reported this issue to our Vulnerability Rewards Program, we worked closely with them to deeply understand it in order to better secure our users," a Google representative said in an emailed statement. "We’ve developed a mitigation which we will include in our upcoming November security bulletin.” Google's mitigation complicates the attack, but it doesn't fix the underlying problem, according to the VUSec researchers. In fact, fixing what is essentially a hardware issue in software is impossible. Hardware vendors are investigating the problem and may be able to fix it in future memory chips, but chips present in existing devices will likely remain vulnerable. Even worse, it's hard to say which devices are affected because there are many factors that come into play and haven't yet been fully investigated, the researchers said. For example, a memory controller might behave differently when the device battery level is under a certain threshold, so a device that doesn't appear to be vulnerable under a full charge might be vulnerable when its battery is low, the researchers explained. Also, there's an adage in cybersecurity: Attacks always get better, they never get worse. Rowhammer attacks have grown from theoretical to practical but probabilistic and now to practical and deterministic.

This means that a device that does not appear to be affected today could be proven vulnerable to an improved Rowhammer technique tomorrow. Drammer was demonstrated on Android because the researchers wanted to investigate the impact on ARM-based devices, but the underlying technique likely applies to all architectures and operating systems.

The new attack is also a vast improvement over past techniques that required either luck or special features that are present only on certain platforms and easily disabled. Drammer relies on DMA (direct memory access) buffers used by many hardware subsystems, including graphics, network, and sound. While Drammer is implemented using Android's ION memory allocator, APIs and methods to allocate DMA buffers are present in all operating systems, and this warning is one of the paper's major contributions. "For the very first time, we show that we can do targeted, fully reliable and deterministic Rowhammer without any special feature," said Cristiano Giuffrida, one of the VUSec researchers. "The memory massaging part is not even Android specific.
It will work on any Linux platform -- and we suspect also on other operating systems -- because it exploits the inherent properties of the memory management inside the OS kernel." "I expect that we're going to see many other flavors of this attack on different platforms," added Herbert Bos, a professor at Vrije Universiteit Amsterdam and leader of the VUSec Systems Security research group. Along with their paper, the researchers have released an Android app that can test if an Android device is vulnerable to Rowhammer -- at least to the currently known techniques.

The app is not yet available on Google Play but can be downloaded from the VUSec Drammer website to be installed manually.

An open-source Rowhammer simulator that can help other researchers investigate this issue further is also available.

App proves Rowhammer can be exploited to root Android phones –...

Hardware vuln strikes 18 of 27 tested mobes Security researchers have demonstrated how to gain root privileges from a normal Android app without relying on any software bug. The unprivileged application is able to gain full administrative permissions by exploiting the Rowhammer vulnerability present in modern RAM chips.

Essentially, malicious code can change the content of memory it should never be able to access. This means rogue mobile applications can abuse this hardware flaw to commandeer peoples' handhelds. The effect is pure physics and yet exploitable through software: RAM is assembled in rows of cells, and it is possible to flip bits in a row by repeatedly accessing the cells in an adjacent row.

By continuously accessing cells, software can trigger voltage fluctuations in the RAM chips' control electronics.

This causes cells in rows adjacent to the one being accessed to discharge faster than normal, meaning they lose the information they were holding. This can be exploited to alter bits in RAM one by one, and manipulate crucial operating system data to gain root privileges. With admin access, the software can completely hijack the device, install malware and spyware, and so on. Most – but not all – Android smartphones are potentially vulnerable to this attack, we're told. A team from Vrije Universiteit, Amsterdam and other academics have documented how this Rowhammer effect, previously demonstrated on Microsoft Edge and public clouds, also affects Android smartphones as well as PCs and servers. The group have developed and released Drammer, which exploits Rowhammer to take control of a mobile device by tampering with its physical memory, proving the attack technique is practical rather than a lab-only exercise.

Drammer has no special permissions – it is a normal unprivileged app – and yet is able to gain root-level access to the device. The researchers explain: The Rowhammer vulnerability allows attackers to change data in memory without accessing it directly, by reading from another memory region exhaustively (hence hammering).

To date, it was assumed that mobile, ARM-based devices would be too slow to trigger these so-called bit flips, limiting Rowhammer attacks to stationary PCs and servers.

This work squashes that common belief and shows how attackers can exploit the hardware bug in a fully deterministic and reliable manner. Drammer – developed in collaboration with the University of California at Santa Barbara and Graz University of Technology in Austria – uses Flip Feng Shui to achieve reliable Rowhammer exploitation. Not every phone is vulnerable to the Rowhammer bug.

The researchers performed bit flips in 18 out of 27 tested phones, including some (former) flagship models like Google's Nexus 5 or the LG G4. Google told El Reg that it had worked out a software fix designed to mitigate against attacks, which will become available in November.

A spokesperson told us: After researchers reported this issue to our Vulnerability Rewards Program, we worked closely with them to deeply understand it in order to better secure our users. We’ve developed a mitigation which we will include in our upcoming November security bulletin. The team that developed the attack warned that Google can only go so far toward resolving what boils down to a hardware problem. “Google scrambled to try and fix the problem, but they cannot really do it as the problem is in hardware,” Herbert Bos, professor of systems security at Vrije Universiteit Amsterdam and supervisor of the research, told El Reg. “Also, since the Android market is so fragmented, this patch will probably never reach most of the phones.” More details of the research are due to be unveiled on Wednesday, October 26, at the Conference on Computer and Communications Security (CCS), a security conference in Vienna, Austria, by Victor van der Veen, lead author of the paper. ®
