Conficker.C Purchase tickets now for the April 1st event
Summary: Conficker.C, also tracked as W32/Conficker.C.worm, WORM_DOWNAD.AD, W32.Downadup and Net-Worm.Win32.Kido.cn, spreads through the same MS08-067 vulnerability as the A and B variants, so the detection released on 2008-10-23 still fires on that spreading mechanism. Cisco Talos notes the C variant added new functionality, and that its researchers are working to add A, B and C DNS name matching to Snort.
What's compelling: A worm family that first drew a detection signature in October 2008 was still adding capabilities by its third variant, and defenders were still retrofitting IDS coverage for its DNS behavior - a reminder that a vulnerability like MS08-067 keeps paying out for attackers long after the patch exists.
