There is a widespread attack underway against an unpatched vulnerability in the Msvidctl DLL, with attackers using thousands of newly compromised Web sites to exploit victims’ PCs via drive-by downloads. The attacks are using Internet Explorer as the attack vector and are pushing a Trojan downloader onto compromised machines.
