For example, an attack that succeeded in locking up the operational data upon which physical processes rely could do serious and potentially even catastrophic damage to people and property.
Considering the severity of the potential consequences of a ransomware attack, plant owners are also likely to be more willing than others to quietly pay up any demanded ransom, CyberX said. The authors of the new KillDisk variant are a cybercriminal group called the TeleBots gang that appears to have evolved from another group called the Sandworm gang, Neray said. The Sandworm gang was responsible for a series of attacks on Industrial Control System (ICS) and SCADA networks in the US in 2014 involving the use of malware dubbed BlackEnergy.
The same group is also believed responsible for the attacks on the Ukrainian power grid in December 2015 and in early 2016 using the same BlackEnergy malware and the hard disk-erasing version of KillDisk. The TeleBots gang itself has been associated with previous attacks on Ukrainian banks and now appear to have turned their sights on companies in the industrial sector. “We know that both BlackEnergy and KillDisk were seen in the Ukraine power attacks and may also have been used in attacks against a large Ukrainian mining company and a large Ukrainian rail company,” says Neray in comments to Dark Reading. The new KillDisk ransomware variant has almost the same functionality as the previous version, but instead of deleting files it encrypts them. “For example, in both samples, the same string encoding algorithm is being used. So it's reasonable to assume that the new ransomware malware was designed [for use] against industrial companies too,” Neray says. In addition, other security researchers too have seen evidence of cybercriminals already targeting chemical plants in Eastern Europe for extortion, he says. It is unclear what malware strains were used in those attacks.
But as with KillDisk, the threat actors behind those attacks used malicious email attachments to distribute their malware and to penetrate the operational networks and processing systems of chemical plants in a way to effect the purity of the output, Neray says.

It was registered to a command and control server (C2) which held stolen keylog data from HawkEye RAT victims, but was also being used as a one-stop-shop for purchasing hacking goods. WhiteHats on the prowl? Before diving into an analysis of the server, it is worth pointing out some interesting behavior spotted in several of the victims’ stolen accounts.
A group of WhiteHat hackers who call themselves Group Demóstenes were found to be working around the clock, trawling the internet and looking to exfiltrate stolen data from C2 servers. When such a server was found, the group looked for a backdoor that would give them control over the filesystem.
They would then monitor the incoming, stolen data.
Either manually or automatically, they would collect the stolen credentials and send emails to the victims’ accounts.
These emails contained an attachment with proof that the user’s machine has been compromised.
In addition, they advise the user to change passwords immediately and offer to help.

The name of the group appears to be of Portuguese origin, though it is not certain. The shopfront: the command and control servers Scanning for network services which are running on the C2, we discovered that it contains not only a back-end for storing stolen credentials but also a front-end for selling some of them, alongside many other “goods”. Browsing the domain that communicated with the HawkEye RAT samples disclosed a login page.
Given the fact that the server was newly operational, it allowed users to register an account and login to purchase the goods on offer. After registering on the C2 web application, there was no sign of the stolen data transferred from compromised machines.
A forum-like web page opens up once a successful login is being processed. The C2 was meant to securely store the stolen data; however, it contained a crucial vulnerability which allowed researchers to download the stolen data. The C2 owners seem to have added six new Shell scripts on 22 November, just a week before the research started – a further indication of how new the operation is. Another item for sale is scam pages, and some are multilingual.
The attackers also reveal the scope of their victims, noting those who are registered to Amazon, Apple, Netflix and even National Bank of Australia and Barclays.
The listing of the year next to the banking information probably refers to how up-to-date the scam pages are in terms of the bank’s website updates. The attackers have spared no details and have added additional information regarding how one should act when using their services, and who to contact in the Support tab. To purchase goods in the private shop you must deposit money into your account on the website.
The attackers accept Bitcoins, PerfectMoney and WebMoney. Back to the stolen data As we described, HawkEye is a robust keylogger that can hijack keystrokes from any application being opened on the victim’s PC.
It can also identify login events and record the destination, username and password.
It is, however, limited to two-factor authentication and single sign-on. Stolen credentials on the server were found to be holding sensitive access passwords to government, healthcare, banking and payment web applications.
Among them is the following web server which belongs to the Pakistani government. As mentioned, hundreds of machines were found to be compromised by just one C2.
The following is a partial list of what was downloaded from the malicious server. Usually, careless threat actors forget to remove test files which might contain sensitive data.
In this case, we were able to obtain the attackers credentials from one very small file that was captured when searching related strings. Target geography The research is still ongoing and is currently affecting users located in APAC, such as Japan, Thailand and India, as well as parts of Eastern Europe such as Russia and Ukraine.
The stolen database may have even included information on email ids of U.S. government and military employees. “It is extremely alarming that Yahoo didn’t know about this,” said Alex Holden, chief information security officer with Hold Security. Yahoo said back in November it first learned about the breach when law enforcement began sharing with the company stolen data that had been provided by a hacker.
At the time, the company was already dealing with a separate data breach, reported in September, involving 500 million user accounts. However, this hacker was apparently sitting on another mother lode of stolen Yahoo data, but it’s still unclear how the theft occurred. Holden, who investigates online black markets, said there was always chatter among underground dealers that someone had made away with a massive trove of information from the internet firm. “Hackers allegedly had small samples, but they had never seen the full data set,” Holden said. But the stolen data never appeared to be widely circulated to make a major profit, he said.
It suggests that state-sponsored hackers may have been behind the breach, and wanted to keep the data secretly to themselves. “This information would have been distributed widely if cyber criminals were involved,” Holden said. “But right now, that seems not to be the case, even two or three years later.” Private security firm InfoArmor may have actually discovered details about the Yahoo data breach earlier this year.
In September, the company claimed it had found a stolen database allegedly belonging to Yahoo that was obtained from elite hackers-for-hire. Yahoo, however, didn’t comment on the company’s finding, making it unclear if the data was legitimate. InfoArmor has claimed that a hacking team called “Group E,” likely out of Eastern Europe, breached Yahoo and sold the data in three private deals.
At least one of the buyers was a state-sponsored actor, said Andrew Komarov, InfoArmor’s chief intelligence officer, in an email on Wednesday. The security firm has shared its findings with law enforcement agencies in the U.S., U.K., Australia and Europe.
It said the stolen database it found also has information relating to over 150,000 U.S. government and military employees.
Backup email addresses included in the discovered dump contain .gov and .mil domain names, said Komarov, who called the Yahoo breach a “matter of national security.” The stolen data “may allow the threat actors to identify government employees very quickly,” he said. The FBI has only said its investigating the Yahoo hack, and on Wednesday, the agency didn’t provide any new details. Yahoo also hasn’t mentioned who might have pulled off the intrusion, except to say an “unauthorized third party” was involved. Still, the recent data breaches at the company highlight the need for the tech industry to constantly be on guard against cyber threats, a security expert said. “The lesson is clear: no organization is immune to compromise,” said Jeff Hill, director of product management for security provider Prevalent, in an email. “Criminal actors can do significant damage in days and weeks; give them years, and all bets are off.”
The remote hack works from anywhere in the world, robbing banks in as little as 10 minutes.
It is every consumer's dream to find an ATM spitting out cash like a winning slot machine, and it seems that hackers in Eastern Europe have figured out how to make that a reality.
As outlined by Russian security firm Group IB, the hackers are linked to the Buhtrap crew, which stole $28 billion from Russian banks between August 2015 and January 2016, according to Reuters. But while Buhtrap looted ATMs via fraudulent wire transfers, the ATM scammers reportedly use a less hands-on method: "touchless jackpotting."
The remote hack works from anywhere in the world, robbing banks in as little as 10 minutes. The hackers reportedly use a penetration testing tool known as Cobalt Strike, which lets them access servers that control ATMs via bank PCs infected by malicious emails. Accomplices then wait by the targeted ATMs and scoop up the cash as it spits out of the machine.
The hackers reportedly hit financial institutions in Armenia, Belarus, Bulgaria, Estonia, Georgia, Kyrgyzstan, Malaysia, Moldova, the Netherlands, Poland, Romania, Russia, Spain, and the UK. Group IB did not reveal which banks were targeted.
Global ATM manufacturers Diebold Nixdorf and NCR confirmed to PCMag that they are "familiar" with these types of breaches.
"ATM attacks are becoming more complex and sophisticated as hackers dedicate more time to attacking infrastructure," an NCR spokeswoman said in a statement. "Securing one's infrastructure and endpoints is a never-ending and extremely important task that does not depend on the region or attack type."
Diebold Nixdorf, meanwhile, claims there is "no indication to us that this group of fraudsters is active in Europe or the Americas."
But that doesn't mean they won't be. "Logical attacks on ATMs are expected to become one of the key threats targeting banks," according to Dmitry Volkov, head of the Group IB investigation department.
"They enable cybercriminals to commit fraud remotely from anywhere globally and attack the whole ATM network without being 'on the radar' of security services," he said in a statement. "This type of attack does not require development of expensive advanced software—a significant amount of the tools used are widely available on the deep Web."
As the Wall Street Journal reports, the FBI recently warned US banks to look out for potential attacks, following incidents in Taiwan and Thailand over the summer.
"Every bank is under threat of logical attacks on ATMs and should be protected accordingly," Volkov added.
Therefore, the European Money Mule Action II is paramount to stop people being lured and recruited into aiding serious crime, to break this crime link, by being aware of who is behind this type of crime." Steven Wilson, head of Europol's European Cybercrime Centre, added: "The European Money Mule Action is a successful example of public-private co-operation at the closest level.
The results of this second edition demonstrate a very strong connection between cybercrime and the illegal transactions identified." Law enforcement agencies from across Europe as well as the FBI and United States Secret Service participated in the international operation.
In addition, 106 banks and private partners supported the crackdown, the second pan-European operation of its type.

The email claims to be from a transport company and suggests that the target has missed a parcel delivery -- encouraging them to fill in a form to rearrange delivery for another date.
It's this form which drops Wildfire ransomware onto the victim's system and locks it down. A spam email used to infect victims with Wildfire. Image: McAfee Labs Researchers note that those behind Wildfire have "clearly put a lot of effort into making their spam mails look credible and very specific" - even adding the addresses of real businesses in The Netherlands - arousing suspicion that there are Dutch speaking actors involved in the ransomware campaign. Working in partnership with law enforcement agencies, cybersecurity researchers were able to examine Wildfire's control server panel, which showed that in a one month period the ransomware infected 5,309 systems and generated a revenue of 136 Bitcoins (€70,332). Researchers suggest that the malicious code -- which contains instructions not to infect Russian-speaking countries -- means Wildfire operates as part of a ransomware-as-service franchise, with software likely to be leased out by developers in Eastern Europe. Whoever is behind Wildfire, victims no longer need to pay a ransom in order to get their files back,with the decryptor tool now available to download for free from the No More Ransom site.
The tool contains 1,600 keys for Wildfire, and No More Ransom says more will be added in the near future. READ MORE ON CYBERCRIME
