Trailrunner7 quotes a report from On the Wire: Vulnerabilities in Flash and Internet Explorer dominated the exploit kit landscape in the last year, with a high-profile bug in Flash being found in seven separate kits, new research shows. Exploit kits have long been a key tool in the arsenal of many attackers, from low-level gangs to highly organized cybercrime crews. Their attraction stems from their ease of use and the ability for attackers to add exploits for new vulnerabilities as needed. While there are dozens of exploit kits available, a handful of them attract the most use and attention, including Angler, Neutrino, Nuclear, and Rig. Researchers at Recorded Future looked at more than 140 exploit kits and analyzed which exploits appeared in the most kits in the last year, and it's no surprise that Flash and IE exploits dominated the landscape. Six of the top 10 most-refquently targeted vulnerabilities in the last year were in Flash, while the other four were in Microsoft products, including IE, Windows, and Silverlight. Flash has been a favorite target for attackers for a long time, for two main reasons: it's deployed on hundreds of millions of machines, and it has plenty of vulnerabilities. Recorded Future's analysis shows that trend is continuing, and one Flash bug disclosed October 2015 was incorporated into seven individual exploit kits. The flaw was used by a number of high-level attackers, including some APT groups. "Adobe Flash Player's CVE-2015-7645, number 10 in terms of references to exploit kits, stands out as the vulnerability with the most adoption by exploit kits. Exploit kits adopting the Adobe bug in the past year include Neutrino, Angler, Magnitude, RIG, Nuclear Pack, Spartan, and Hunter," the analysis by Recorded Future says.
