Nine-Ball Compromises more than 40,000 Legitimate Web Sites

Websense reports about a large mass injection attack that has so far compromised thousands of web sites. "We have been tracking the Nine-Ball mass compromise since 6/03/2009. To date, over 40,000 legitimate Web sites have been compromised with obfuscated code that leads to a multi-level redirection attack, ending in a series of drive-by exploits that if successful install a trojan downloader on the user's machine", writes Websense.

This is the third time within a short period when a big amount of web sites gets compromised. Earlier two mass injections were made by Gumblar and Beladen.
