What's going on with Warezov on ICQ?
A few weeks ago our network provider reported that they caught a few HTTP requests (a few GET for map.src and picture.pif) to a known warezov domain coming from one of our ip. Warezov and its variants are easily trackable since once activated they will try to update themself by fetching an update on several domains created for this purpose. So, a computer was suspected to be infected on our networks. I investigated and discovered that the actual IP involved was a linux box. No, not even a dual boot box.
After asking the lady who used to computer that day, i understood that she certainly didn't go fetch the warezov update on purpose and that she only used meebo.com (webmesenger service) and yahoo mail. She reported a few weird messages from people she didn't know on ICQ, though. A few days later, another user reported the same kind of messages on ICQ, but this time from an unknown warezov domain! No antivirus vendors are actually linking Warezov and ICQ. So what's going with Warezov on ICQ?
Renater our network provider reported these requests, saderuikuntunyesdea.com being a know warezov domain:
GET http://281.saderuikuntunyesdea.com/1/2772/ - DIRECT/184.108.40.206 text/html GET http://281.saderuikuntunyesdea.com/chr/IM/map.scr - DIRECT/220.127.116.11 text/plain GET http://2298.saderuikuntunyesdea.com/2/4460/picture.pif - DIRECT/18.104.22.168 text/html GET http://2298.saderuikuntunyesdea.com/chr/IM/picture.pif - DIRECT/22.214.171.124 text/plain
The lady who used the computer at this time couldn't actually remember what were the messages sent to her on ICQ, but she certainly didn't remember clicking on any of them.
I couldn't find any information linking warezov and ICQ. According to Sunbelt warezov is a mass mailing worm that carries an infected attachment and spreads by sending a copy of itself to every email address in the victim's computer.
Anyway, i downloaded the map.scr and picture.pif files and submitted them on virustotal.com:

It's abviously a piece of warezov. I reported it to f-secure with my little story and then contacted me back saying the files i submitted didn't have any IM related routines. They said the virus was probably not sent on ICQ but rather in a mail. But a few days later another user reported weird messages on ICQ and this time, she sent them to me:
check this http://7692.seruijingandeshijinpos.com/1/3030/ check this http://9842.seruijingandeshijinpos.com/1/4619/
Interesting.. this time we're sure it's coming from ICQ and that it's a warezov even though seruijingandeshijinpos.com isnt a know warezov domain (yet). I reported this to my contact at f-secure and am still waiting for an answer...
