Technical Details

This trojan-downloader is falsely distributed as an update for the Flash Player, in an unsigned executable file with the name "update.exe".

On installation, the malware attempts to connect to a remote server and download additional files onto the infected machine.

The remote server the malware contacts is known to be part of a botnet. At the time of writing however, the malware's file download behavior is inactive, possibly due to the remote server being taken offline.
