Empornium.us, the world’s largest adult-material tracker, has been blocked by Google and Firefox today.

Currently those who search Google for Empornium are met with a warning under the URL: “This site may harm your computer“. If they choose ignoring the warning and clicking the link on IE, the site main page will load but then anti-virus software may periodically show virus/malware warning messages. Users using Firefox 3 to access the site URL also meet a “Reported Attack Site” warning as the following screenshot:

“Malicious software includes 4 trojans, 3 exploits. Successful infection resulted in an average of 11 new processes on the target machine,” reported Google.

TorrentFreak contacted Empornium team for comment and they said that the malicious code has nothing to do with them but they are now “taking action to shut down the infiltration & remove the code asap“.

It is “exploiting a known & patched security hole in Acrobat,” reported the team about how the site was infected.
