2013-12-24 - Exploit Integration

CVE-2013-5329 integrated in Exploit Kits



Disclaimer :  I may hide informations if a CVE try seems broken.

Fast post that I will heavily edit later with details and other integration (if some).

Angler EK is not a Reveton dedicated EK anymore. After being adopted by the "ru:8080" team,

 I spotted another customer few days ago (will update with Screenshots and information on payloads)

Studying it I found that Angler EK has integrated a new Flash Exploit.
I can't tell for now which one. Best candidates were CVE-2013-5329 and CVE-2013-5330 as Flash 11.9.900.117 was successfully exploited. These exploits have been patched on 2013-11-12 (see: http://www.adobe.com/support/security/bulletins/apsb13-26.html ). Angler won't try to exploit Flash 11.9.900.152 and 170.

<edit1 2013-12-25>
Thanks Arseny Levin from SpiderLabs for defining the correct CVE, Chris Wakelin for decoding the RC4ed SWF  and Will Metcalf from Emerging Threats for additional inputs

I can now update the post with CVE-2013-5329.
More technical data to come later

One question...How did they get that code...
I guess 450k$ budget for exploits helps.

Thanks @EKWatcher, @node5 and @TimoHirvonen for help.

Since few months it seems that targeted victims are only UA/RU and maybe one "customer" only (Payload : Russian ransomware)
