A new version of the IcePack hacker exploit tool kit has been released, security researchers warned today, and for the first time it includes attack code designed to exploit an unpatched, or zero-day, Microsoft vulnerability.

Three of IcePack's eight exploit tools are new, said Roger Thompson, chief technology officer at Exploit Prevention Labs Inc. That's noteworthy in and of itself, Thompson said. "The mix of old and new exploits is to be expected, but three new ones in one update is pretty impressive," he noted.

But the new tool kit also sports a first. "The latest iteration has done something original," said Thompson, pointing to an exploit that attacks a zero-day vulnerability in Microsoft's DirectX software development kit (SDK). "The closest to a tool-kit zero-day exploit [before] was for the ANI [animated cursor] vulnerability."

He was referring to a Windows bug that surfaced in early April. By the time that Mpack, an IcePack predecessor, added the ANI exploit, however, Microsoft had patched the vulnerability with an emergency out-of-cycle update.

The DirectX SDK bug was disclosed by Polish researcher Krystian Kloskowski in a post to the milw0rm.com site in mid-August. Microsoft did not release a fix for the flaw in the regularly-scheduled updates issued earlier today.

IcePack is only one of several click-to-attack malware tool kits in circulation. Derived from the earlier Mpack, IcePack joins others boasting monikers like NeoSploit and WebAttacker that cater to what Thompson called "lazy crooks."

"Originally there was just WebAttacker, but they screwed up and then NeoSploit came along," Thompson said as he rattled off the exploit tool kit genealogy. "Then there was Mpack, which everyone at first thought was just WebAttacker, but it wasn't. Now there's IcePack." He estimated that nine to 12 malware tool kits are currently in use.

"They all use very similar code, and they're all trying to make a buck out of selling to lazy crooks," said Thompson.
