Changelog spam / Changelog_Urgent_N992.doc.exe

This fake "changelog" spam has a malicious attachment Changelog.zip which in turn contains a malware file named Changelog_Urgent_N992.doc.exe

Subject:      Re: Changelog 2011 update

as promised changelog,

VirusTotal detects the payload as Cridex. The malware is resistant to automated analysis tools, but Comodo CAMAS reports the creation of a file C:\Documents and Settings\User\Application Data\KB00085031.exe which is pretty distinctive.

If your email filter supports it, I strongly recommend that you configure it to block EXE-in-ZIP files as they are malicious in the vast majority of cases.
