MSN Worm outbreak

[Post on : June 1, 2007 18:00 | Category : Bot & Botnets | by : smallmo] Reship : Original

Since this afternoon, lots of Chinese MSN users have received the same file "photos.zip". It's a new IM-Worm and spreading very quickly in China. This worm can send messages in English, French, Spanish and so on, such as "My friend took nice photos of me.you Should see em loL!","hey regarde les tof, c'est moi et mes copains entrain de.... :D",etc. We declared a medium alert for Chinese users on 5:30 p.m, June.1, 2007(GMT +0800). Everyone should be careful of this new worm.

The screenshot of messages:

Open in new window

In the .zip file, there is a file "photos album-2007-5-26.scr", size is 479,232 bytes, MD5 hash is 9784ab71076f583ce02de0340554aefa.

Open in new window

Upon execution, it drops a file "syshosts.dll" and modify a regestry key:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\ShellServiceObjectDelayLoad
"syshosts" = "{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}"


Sends messages as the following:
