If you happen to receive messages from any of your MSN Messenger contacts similar to these:
Accept dis picture homie
Accept dis picture homieDid you see this picture of Paris Hilton?
Is this you?
…and followed by a ZIP file sent to you; do not open whatever is in the ZIP file. This seems to be one of the newest MSN Messenger worm making the rounds.
I’ve yet to see any information regarding this potential malware. I’ll update if I find out more information. Searches on Symantec and Kaspersky returned nothing at the time of this post.
Update: So far, I had three attempts to send the file to me, and in all instances the file name is imgac157.zip. When I extracted the contents, there’s only one file called img1851.jpg-www.imagehosting.com.
Update 2: This morning (9:00am, 23 August 2007) AVG detected the virus as Backdoor.Ircbot.BAF. It must have been included in the latest definition update.
