New WMF exploit attacks via email Posted by Mikko @ 09:38 GMT

HappyNewYear.jpgSome clown is spamming out "Happy New Year" emails which will infect Windows machines very easily. These emails contain a new version of the WMF exploit, which doesn't seem to be related to the two earlier Metasploit WMF exploits we've seen.

The emails have a Subject: "Happy New Year", body: "picture of 2006" and contain an exploit WMF as an attachment, named "HappyNewYear.jpg" (MD5: DBB27F839C8491E57EBCC9445BABB755). We detect this as PFV-Exploit.D.

When the HappyNewYear.jpg hits the hard drive and is accessed (file opened, folder viewed, file indexed by Google Desktop), it executes and downloads a Bifrose backdoor (detected by us as Backdoor.Win32.Bifrose.kt) from www[dot]ritztours.com. Admins, filter this domain at your firewalls.

It's going to get worse.
