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 »

Microsoft Update Tuesday January 2015: Another Light Month, No IE Bulletins, More Changes to Reporting

This post was written by Yves Younan.

Microsoft’s first Update Tuesday of 2015 is pretty light, there’s a total of eight bulletins, all covering a single vulnerability. Seven of these bulletins are rated as important and just one is rated critical. No bulletin for IE is being released this month. Two of the vulnerabilities were publicly disclosed prior to today, while another one was being actively exploited by attackers.

Microsoft made a number of changes to Update Tuesday last month, such as dropping deployment priority in favor of their exploitability index (XI). This month more changes were made to the program: Microsoft is no longer providing their Advance Notification Service (ANS) to the general public, but is instead only providing it to premier customers.
