Europol: Cybercrims getting more devious Europol’s annual cyber-crime survey warns that the quality of spearphishing and other "CEO fraud" is continuing to improve and "cybercrime-as-a-service" means an ever larger group of fraudsters can easily commit online attacks. Many threats remain from last year – banking trojan attacks are still an issue for businesses and individuals although this has now been eclipsed by ransomware which is growing more quickly. The ease of access to cyber-crime tools means that it now exceeds real world crime in terms of value in many European countries. The report warns that although there is very limited use of these tools by extremist groups, the fact that they're simple to use, and fairly simple to access via the Dark web, means that could quickly change.
It notes that such groups make wide use of social media for propaganda and recruitment there is little evidence of use of cyber-attack capabilities beyond website defacement. Europol is also seeing the first evidence of organised criminal gangs beginning to exploit contactless cards. It warns of increasing use of booter/stresser tools to run DDos attacks. It has also seen a marked improvement in the quality and apparent authenticity of spear-phishing attacks – making them ever harder to separate from genuine communications. Data remains a key target for cybercrims.

But they’re increasingly using it either to encrypt, for ransom, for direct extortion or to further more complex fraud, not just for immediate gain. Another change this year is an increase in live streamed child sexual abuse. Europol said: “The use of end-to-end encrypted platforms for sharing media, coupled with the use of largely anonymous payment systems, is facilitating an escalation in the live streaming of child abuse. Offenders target regions where there are high levels of poverty, limited domestic child protection measures and easy access to children.” Beyond recommending more resources for cyber-crime law enforcement Europol wants more collaboration and intelligence sharing to deal with Darknet investigations and prevent duplication of effort and improve sharing of tools and tactics. More broadly it calls for a phenomenon-based approach to replace incident response.
It notes that successes in combating fraud in the airline industry could be replicated for other industries.

Equally operations to target offenders who need to be in a physical location – like car rental – in order to collect the proceeds of cyber-crime. The full Internet Organised Crime Threat Assessment 2016 is available to download here.
A Fortinet research report finds that manufacturers are increasingly under attack from ransomware as older vulnerabilities provide easy access. The scourge that is ransomware is spreading in the manufacturing sector, according new research from Fortinet. Over the course of seven months, from Oct. 1, 2015, to April 30, 2016, Fortinet recorded 8.63 million attempted attacks against 59 manufacturers around the world.The attacks were mostly aimed at the larger manufacturers, with 78 percent of them targeting manufacturing organizations with 1,000 or more employees. Also of note is that out of the 8.63 million attacks, 29 percent were from a Trojan called Nemucod, which carries ransomware as part of its malicious payload.Ransomware has been a growing concern in 2016, with the FBI warning in May of a significant uptick in activity.

Among the high-profile ransomware incidents have been a series against hospital operations that quite literally have put lives at risk.There are a number of reasons why ransomware attacks on the manufacturing sector are successful, not the least of which is because they take advantage of known exploits.

Fortinet's Q1 2016 Cyber Threat Assessment Program (CTAP) report, which examines the period from Jan. 1 to April 30, 2016, reported that the Necurs botnet is the most prevalent in manufacturing at 41.46 percent, followed by Conficker at 17.7 percent. Conficker is notable because it's a worm that first attacked Microsoft systems back in 2008 and was patched by Microsoft in that same year. Yet despite the fact that Conficker was patched seven years ago, it's still a problem in manufacturing. "Most exploits are still attacking solved problems," John Maddison, senior vice president of products and solutions at Fortinet, told eWEEK. "It's those who do not patch who are most at risk."A lot of solved problems are ultimately exploited, according to Maddison. Looking specifically at application vulnerability exploit attempts in the manufacturing sector, Fortinet found that 82.8 percent of attempts were against CVE-2015-6125, which is a Microsoft DNS caching vulnerability that Microsoft patched as part of its December 2015 Patch Tuesday update.
In its advisory, Microsoft stated that the vulnerability could allow remote code execution if an attacker sends specially crafted requests to a DNS server.Coming far behind in second place, in terms of manufacturing sector application vulnerability exploit attempts, is the combination of CVE-2014-7169 and CVE-2014-6278, better known as Shellshock.

The Shellshock vulnerabilities were patched in September 2014.

Even older than Shellshock and Conficker is the third place vulnerability (at 4.34 percent), identified as CVE-2007-1365, an OpenBSD IPv6 fragment buffer overflow issue.There are a number of things that manufacturers should be doing to help limit the risks of ransomware and attacks.

Fortinet suggests that an organization should be protecting, monitoring and segmenting all of its data.

The segmentation piece is of particular importance as a "flat" (non-segmented) network provides an attacker an easier path to move around a network from an initial point of compromise.Sean Michael Kerner is a senior editor at eWEEK and InternetNews.com.
