From Gimmiv to Conficker: MS08-067 Under The Microscope

GENEVA — The critical MS08-067 vulnerability used by the Conficker worm to build a powerful botnet continues to be a lucrative security hole for cybercriminals.
During a presentation at the Virus Bulletin 2009 conference here, a trio of Microsoft researchers dissected the malware attacks linked to MS08-067 and found that criminal gangs are still exploiting the flaw to plant data-theft Trojans on vulnerable Windows machines.

Security researchers at penetration testing firm Immunity have created a reliable remote exploit capable of spawning a worm through an unpatched security hole in Microsoft’s dominant Windows operating system.

A team of exploit writers led by Kostya Kortchinsky attacked the known SMB v2 vulnerability and created a remote exploit that’s been fitted into Immunity’s Canvas pen-testing platform. The exploit hits all versions of Windows Vista and Windows Server 2008 SP2, according to Immunity’s Dave Aitel.
