Sandi at Spyware Sucks
reports that the popular(ish) Facebook game of
FarmTown (not FarmVille) has be compromised, possibly through a malicious banner.
The domain
justimpression.com has been fingered as part of the malware chain, registered to the infamous "Private person" of:

ns2.reg.ru
ns1.reg.ru
That email address is
pretty well known for malware distribution.
The site is hosted on 64.120.176.42 along with a site called
impressionclub.com. "Impression Club" claims to be a Pennsylvania based company that has been in business for four year, except the domain was only registered in January 2010 with anonymous contact details, and Russian nameservers.

You can probably count impressionclub.com as a rogue ad network and one to avoid.
The FarmTown developers have a forum
thread about the problem (one poster identifies an ad for
greetingcards.com as the culprit) and there are several threads on Facebook about this [

- scan-and-protect3.com
- scan-and-protect5.com
- scan-and-protect7.com
- scan-and-protect8.com
- scan-and-remove10.com

- try6-your-scanner.com
- 111-your-scanner.com
- 222-your-scanner.com
- basketballtickets2.com
- batman2010.com
- spread2010.com
- terminator-2010.com
All these domains are registered with apparently false details, there are probably a bunch more but I'm having difficult resolving the IPs at the moment.
This could be a fairly big deal,
Quantcast reports that justimpression.com has a traffic rank of 6,227 and pulled in 329,000 US visitors during February.

This is another good reason to block Facebook in corporate enviroments, and also a useful warning that you need to be very, very careful when selling ad space!
