This morning the Celebrity spam campaign continued with a few new fake video codec sites delivering a downloader Trojan designed to install a fake security product known as AntiVirus XP 2008. It’s apparent now that a number of these spam campaigns are only interested solely in distributing this one particular fake security product. The file downloaded is called video99.exe or video66.exe and varies depending on the email message and the site used (HTML page names often correspond to the binary used index99.html, index66.html, etc).
Some of the subject lines of this particular spam campaign is:
“John McCain to Paris Hilton: Cosmo, baywatch!”
“Britney Spears Shaves Head at Request of Zombie Overlord”

This morning the AV XP 2008 spammers were at it again with another round of spam messages claiming to offer an update to Microsoft Windows Vista (we have seen similar attacks before offering false updates). However, when the user clicks the link he/she is directed to a malicious .swf that will download the file install.exe which essentially is a downloader Trojan designed to install AV XP 2008.

A couple of minutes ago another round of spam messages appeared claiming to provide information concerning a statement of fees recently posted (inferring to banking account fees). The message contained an attachment with a fake Microsoft Word Document which actually is an executable (Fees-2008_2009.doc.exe) that installs a Trojan Downloader.
Further analysis indicates that the Trojan when installed connects to a php page hosted on a Russian domain to obtain several possible sites as a means of downloading the installer for AntiVirus XP 2008. The actual URLs are contained within this script and the file which is downloaded is lspr.exe (MD5 ffccd0518b04354532c733674c0faa00) and is identified as Adware/AVXP2008.

Spammers continue their efforts today with another round of celebrity oriented spam designed to entice users into watching a non-existent video. The fake video site exhibits the same behavior found in the CNN and MSNBC spam attacks covered earlier this month (i.e. a popup message indicates that the ActiveX movie control is out of date and the user is required to install an update to properly view the video).
The executable the user is forced into downloading and installing is known as install.exe or classified as a malicious Trojan - Trj/Exchanger (this particular threat will install AntiVirus XP 2008). It is apparent that the spammers are very interested in getting a large number of users to install and use false security products such as AV XP 2008 and it’s variants in an effort to generate revenue.

This morning we detected another spam campaign with the aim of enticing users into downloading and executing a file they believe is a 6 month trial of a product called “Anti-Virus Nero Advanced Pro 2009“. When analyzed further the file is actually a variation of the rouge antivirus application known as AV XP 2008 which has been seen in earlier attacks this month.
When we look at this further it appears the same group behind the attacks that delivered the fake CNN Alerts and MSNBC alerts could have also been behind this latest round as well. Over the last couple of weeks a large number of emails have been sent that in some degree installed the AV XP 2008 (i.e. fake I.E Update, some of the CNN alerts, celebrity videos).
