Worm Alert

Watch out for a new AIM worm:

A computer worms that spreads via instant messaging is being used to build an extensive “botnet” of remote-controlled PCs, a US security firm has warned.

Security experts at US company FaceTime identified the worm as “W32.pipeline” and warned that it spreads via AOL’s instant messenger program.

The worm disguises a malicious executable program as a jpeg image, which is attached to an instant message that appears to come from someone on the recipient’s AOL “buddy list”.

Typically, the picture is accompanied by the message, “hey would it be ok if I upload this picture of you to my blog?” although another similar message may also be used.
