If you have a Windows PC, do you have a virus scanner on it? Are you sure it is working?
Our Virus guys (well, anti-virus actually :-) ) thought their software was working correctly, but because of the DNS logging I installed, I was able to prove that there was something wrong nevertheless.
Looking at those logs, I see DNS queries for domains such as
mtntdjlfkcv.org, etc. Hundreds of them. Whom do they belong
to? Let's see:
$ whois mtntdjlfkcv.org Domain Name:MTNTDJLFKCV.ORG Registrant Name:Conficker Cabal ... Admin Name:Conficker Cabal ...
My first thought is: boy, are they cheeky, registering their domains under the name "Conficker Cabal". ;-)
In fact, Conficker Cabal is an alliance to
combat Conficker, the savage Windows worm
Case in point, however, is that I'm right. Those PCs are infected with the Conficker worm, and that's it.
As to why the AV-scanner doesn't find it? No idea, but I'm sure somebody is looking into the situation, at least I hope they are.
