We’re seeing a surge in IM-worm activity today. We’ve been seeing a higher level of activity for this type of attack for the past couple of weeks now.
If you receive a file over Yahoo! or MSN Live Messenger service that looks like image021.zip, DO NOT download it. It drops what appears to be a keystroke/vpad scraping bot that phones home to an ip address in Turkey. It also downloads more components from servers in Shanghai and New Zealand.
Here is a screenshot of the MSN Live Messenger client handling the incoming message. The incoming message arrives from one of your contacts as image021.zip, or something close to that name. It arrives alongside a cute message listed below. In our lab, the zip file arrived underneath
“hey look @ my cute new puppy ”
These lines of text are being changed by the authors/distributors. They maintain a “chat.txt” file that is downloaded by the bot from a server in Austria containing all the comments that the worm may chat. Here are the current cute comments the message might arrive as:
hey look @ this picture of me, when I was a kid
I just took this picture with my webcam, like it?

Note- you can observe the struggle that this poor soul went through after downloading, unzipping and running the “album1of42.zip” file they received over MSN Messenger. They unfortunately are seeking out volunteer advice for the time consuming steps of cleaning up a system infected with this worm.
Update: This same sort of IM-worm activity will surge in different parts of the world six months from now.
