The Register has reported that over 10,000 websites have been hacked. These sites were infected by a Trojan downloader and it installs a malware on the computers of users who visit one of the sites.

Paul Ferguson of Trend Micro, a security firm, said that the number of infected sites jumped from 1,100 to 2,500 between the days of Friday and Sunday.

“It’s all over the map. The sheer numbers right now are keeping us pretty busy. All this Web 2.0 stuff is going to turn in to Web uh oh!” said Ferguson.

It is known that the redirected sites use an MPack attack kit. Symantec said that this MPack is “a professionally written collection of PHP software components designed to be hosted and run from a PHP server with a database backend.”
