FaceTime Security Labs has announced yesterday that the recently discovered sdbot.add worm infesting AOL's instant messaging programme could be linked to malware sent by a malicious group in the Middle East.

The security firm also said that it has discovered a rootkit-linked ster.exe file -- containing six secondary files -- which allows the hacker complete access to the infected PC, for downloads, uploads and monitoring purposes.

The group remains unidentified.
