Flash 0-day Exploited by Angler Exploit Kit

This post was authored by Nick Biasini, Earl Carter and Jaeson Schultz

Flash has long been a favorite target among Exploit Kits (EK). In October 2014 the Angler EK was believed to be targeting a new Flash vulnerability. The bug that the Angler exploit kit was attempting to exploit had been “accidentally” patched by Adobe’s APSB14-22 update. According to F-Secure, the vulnerability that Angler was actually attempting to exploit was an entirely new bug, CVE-2014-8439. The bug was severe enough that Adobe fixed it out-of-band.

Fast forward to January 2015. With the emergence of this new Flash 0-day bug, we have more evidence that the Angler Exploit Kit developers are actively working on discovering fresh bugs in Flash for themselves. The group is incorporating these exploits into the Angler EK *before* the bugs are publicized. Considering these 0-day exploits are being used alongside one of Angler’s preferred methods of distribution, malvertising, thus intensifying the potential for large-scale compromise. Read More »

Happy New Exploit Kits! (I mean Happy Belated New Year!)

It’s only been a few days since we said goodbye to 2012 and we are already seeing what many predicted for 2013: an increase in the creation, enhancement, and usage of numerous exploit kits by cyber criminals. Cyber criminals don’t take long vacations in December. On the contrary, they “work hard” and make lots of money during the holiday season! These criminals are continuously improving their tools to keep up with us (the good guys) and continue enhancing their “money-making machines.” A real-life example is how cyber criminals were able to quickly incorporate the exploits of the recently found Java vulnerability that I described in a post a few days ago.

Exploit kits make it easy for these criminals because they can easily spread malicious software that exploits well-known and new vulnerabilities. New exploit kits are loaded with some of the most dangerous zero-day exploits and other features that allow criminals to increase their profits.
