We received a sample of a Word document exploiting CVE-2012-0158 which I took a look at. The file itself is pretty small (325Kb) and based on VirusTotal's MD5 hash report, 30/47 scan engines detected and confirmed it exploits CVE-2012-0158. I used the malwr sandbox to get a better look on how this Word document behaves while running on a Windows system. The one thing I noticed is Yara was positive to check if the file is running in a virtual machine.
