On Nov. 26th, Computer World Security published an article on the new variants of the MS08-67 Windows Server Service Exploit. The variants called "Conflicker" by Microsoft and "Downadup" by Symantec have spread outside Asia to the U.S. and other countries: http://www.microsoft.com/security/portalEntry.aspx?Name=Worm%3aWin32%2fConficker.A
The new variants apparently also attempt to connect to several urls: getmyip.org, getmyip.co.uk and checkip.dynsdns.org. The another interesting piece is that the worm has been reported to reset the computers restore point.
