New AIM worm may prove difficult to fight

Now we have IM worms! Soon VoIP worms.

"A sophisticated computer worm spreading via AOL Instant Messenger is setting up a botnet that may be difficult to combat, security researchers said. The worm, known as W32.pipeline, propagates when AIM users click on a Web link that appears to have been sent to them by someone on their buddy list. They receive a message along the lines of, "Hey, would it be okay if I upload this picture of you to my blog?" If the recipient clicks on the link, an executable file that looks like a JPEG will download into a Windows folder, according to researchers at security company FaceTime Communications Inc. The file can then execute a number of different attacks, said Chris Boyd, security research manager at FaceTime Security Labs and the researcher who discovered the worm. "
