An Overview of the Actual Gen:Variant.Graftor.15447 Attack

This document uses an exploit which attempts to load a video file in MP4 format from a malicious IP address. This MP4 file is not a real video file, using only the header in order to fool your computer system into believing that it is an MP4. In reality, when Adobe Flash attempts to run it, it triggers a known exploit in this application, known as the CVE-2012-0754 exploit, which allows Gen:Variant.Graftor.15447 to drop an executable file included within the original Microsoft Word document. The actual MP4 file manages to bypass anti-virus software because it streams from the web, which means that by the time an anti-virus program can scan it, it is too late. The executable file embedded in the DOC file is also very well hidden, obfuscated in various ways to prevent its detection. Gen:Variant.Graftor.15447 is the actual backdoor which is installed through a remote server in China. Once Gen:Variant.Graftor.15447 is installed, Gen:Variant.Graftor.15447 connects to its control server and waits for orders from the criminals behind Gen:Variant.Graftor.15447.

Gen:Variant.Graftor.15447 is Clearly a Targeted Attack

PC security analysts tend to create email accounts that are purposefully designed to attract spam. It seems that the Gen:Variant.Graftor.15447 attack has not targeted these kinds of accounts or the general public in particular. This malware threat has been found among emails coming from a massive phishing attack from an entity known as Operation Aurora, in China.
