New Year's Waledac Card

We haven't seen a new version of Waledac since Independence Day (July 4, 2009), but it looks like its back!

I'm on vacation today, so I was actually alerted to the story by a friend twittering this SC Magazine story. Vacation or not, that was worth checking into. I took a dip into the UAB Spam Data Mine looking for domain names associated with this version of the malware.

We've seen more than sixty different Subject lines used by the spam:

Some of these domains are already published in MalwareDomainList.com, such as:

noloid.com/wcap.exe - this one is a Fake AV dropper. Here's the VirusTotal report showing 19 of 40 detects:

File size: 230994 bytes
MD5 : ab585c87652c933f82bbaddfd52ea15d
SHA1 : a142cb266ad6cd764501981f6bb194025b7c8cc8

gumentha.com/ecard.html

gumentha.com/counter.php
- this actually causes a download from biozcgicfziy.com/nte/TREST1.php

gumentha.com/in2.php
- this one causes a download from domoktov.com/bu1/
- (you'll be shocked to learn that domain is registered to someone in St. Petersburg, Russia . . .one Denis Sergunkin already known to be hosting Fragus Exploit kits on other domains of his, such as 1tomohappy.com and funky-soft2.com)

purgand.com/in5.php
- this one also hits domoktov.com/bu1/

aweleon.com/ghost.php
- that one ALSO hits domoktov.com. So, Denis? are you paying the Waledac gang? or ARE you the Waledac gang?


This time around the Waledac domains are hosted using Fast Flux, and they are also using Fast Flux for the Nameservers. As we've discussed before, this means that the addresses of the compromised computers are entered into the nameserver records as the host addresses for the malware domains. In other words, getting infected makes your computer spread the infection. So far we've seen more than 1500 computers being used by the malware in this way.



I'll load up a Virtual Machine in a bit to evaluate the actual malware.


Facebook Zbot Still Spreading



We're also seeing an on-going fake Facebook update, which is the Zeus bot. Here are the 45 domains we've seen in the UAB Spam Data Mine so far this morning:

Trying a new setting. After turning on comments, I got about 20-30 comments per day that were all link spam. Sorry to require login, but the spam was too much.
