Sites Load Trojans to watch Free Porn

[gonzo]

One of readers has come across a forum with posting on free porn movies links:
http :// free-bdsm-movies. info/movies/1270174.avi
(Resolves to 85.255.119.210)

However, clicking on the link will open to another site in an iFrame:
http : //www. x-ratedclips.com/bdsm/dp/s5g2/movie1.php?bgcolor=000000&border=3C4553&id=1651
(Resolves to 81.0.250.226)

The x-ratedclips.com page has HTML code that checks for the presence of a Trojan (Zlob.Trojan). If it is not found, it will display a page to tell the viewer that the movie cannot be played and to download a "missing Video ActiveX Object".

The "activex object" link is
http: // www. amultimediasource.com/download.php?id=1651
(Resolves to 85.255.113.222)

Note: 85.255.112.0 - 85.255.127.0 is a known source of evil (http://isc.sans.org/diary.html?storyid=1811)

Not surprising, the downloaded file is actually a Trojan. Positive scan result from VirusTotal:
