CVE-2012-1535 - 7 samples and info


I was still writing my analysis when Alienvault posted CVE-2012-1535: Adobe Flash being exploited in the wild and mine would be pretty much the repeat of the same. I don't like repeating so I will just post the samples and link to Jaime Biasco's article.  As you see from SSDeep they are nearly identical in size, exploit, and payload. All Word documents were authored by "Mark" and have same strings and indicators present as in the analyzed file.

CVE #

CVE-2012-1535
Unspecified vulnerability in Adobe Flash Player before 11.3.300.271 on Windows and Mac OS X and before 11.2.202.238 on Linux allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted SWF content, as exploited in the wild in August 2012 with SWF content in a Word document.

  4. Yesterday Adobe released APSB12-18, which addressed CVE-2012-1535. As noted in the Adobe bulletin, the vulnerability has been actively exploited in the wild, though primarily in targeted attacks wrapped in Microsoft Word documents.
