Java OSX CVE-2012-0507, CVE-2011-3544 and Flashback.35/J sample




Dr. Web published BackDoor.Flashback.39 (Flashback.K-11th variant) epidemic chronology to augment their discovery of the Mac botnet "Doctor Web exposes 550 000 strong Mac botnet".  In general, the Flashback OSX epidemic started on or before August 2011 (F-Secure) with variants distributed as a fake Adobe Flash player. In January 2012, Intego reported Flashback.35/ J (the 10th) which was also distributed as a fake Flash download.

 I am posting here 3 Java exploits used to distribute Flashback trojans:

SAMPLE 1 JAVA CVE-2012-0507 is dated April 4, and appears to be distributing Flashback.35/J - as seen from the payload
SAMPLE 2 is java_signed_applet social engineering exploit (see Michael Schierl's comment below)
and 3 is JAVA CVE-2011-3544 and are dated February 2012.


I don't know which domains distributed these exploits (let me know if you do) but perhaps we are seeing the malware distribution scheme common for Windows-targeting exploit packs
