Tuesday Fun With Microsoft

The new patches are here, the new patches are here!

Microsoft Patches 17 Bugs in December Patch Tuesday

Microsoft fixed 17 bugs in the Windows operating system, Microsoft Office, Windows Media Player and Internet Explorer. The fixes also cover a zero-day flaw exploited by the Duqu Trojan.

Microsoft released 13 security bulletins to fix 17 different vulnerabilities as part of its December Patch Tuesday update, according to the advisory released Dec. 8. Three bulletins were marked critical and the remaining 10 were rated important.

Beyond Stuxnet

Looks like someone, and I’m guessing it’s not the Anonymous script kiddies, is getting ready to open a serious can of cyberwarfare whoop ass on someone.

W32.Duqu: The Precursor to the Next Stuxnet

On October 14, 2011, a research lab with strong international connections alerted us to a sample that appeared to be very similar to Stuxnet. They named the threat “Duqu” [dyü-kyü] because it creates files with the file name prefix “~DQ”. The research lab provided us with samples recovered from computer systems located in Europe, as well as a detailed report with their initial findings, including analysis comparing the threat to Stuxnet, which we were able to confirm. Parts of Duqu are nearly identical to Stuxnet, but with a completely different purpose.

Duqu is essentially the precursor to a future Stuxnet-like attack. The threat was written by the same authors (or those that have access to the Stuxnet source code) and appears to have been created since the last Stuxnet file was recovered. Duqu’s purpose is to gather intelligence data and assets from entities, such as industrial control system manufacturers, in order to more easily conduct a future attack against another third party. The attackers are looking for information such as design documents that could help them mount a future attack on an industrial control facility.

Duqu does not contain any code related to industrial control systems and is primarily a remote access Trojan (RAT). The threat does not self-replicate. Our telemetry shows the threat was highly targeted toward a limited number of organizations for their specific assets. However, it’s possible that other attacks are being conducted against other organizations in a similar manner with currently undetected variants.

A couple of conclusions come to mind. First, the fact that Duqu is based on Stuxnet and the Stuxnet source code has never been released makes it a sure bet that the authors are one in the same, namely Israel and/or the United States, Second, the fact that Duqu is clandestinely collecting information from European manufacturers of industrial control system software, specifically software that controls nuclear facilities, strongly suggests that the eventual primary target of the apparent pending cyberattack will, once again, be Iran’s nuclear program.

/in other words, Duqu is setting up a cyberassault that will hopefully finish, once and for all, the job that Stuxnet so effectively started, halting Iran’s quest for a nuclear weapon in its tracks without having to bomb the [expletive deleted] out of their nuclear facilities

Super Bot

This sure looks like a nasty piece of work.

Massive botnet ‘indestructible,’ say researchers

A new and improved botnet that has infected more than four million PCs is “practically indestructible,” security researchers say.

“TDL-4,” the name for both the bot Trojan that infects machines and the ensuing collection of compromised computers, is “the most sophisticated threat today,” said Kaspersky Labs researcher Sergey Golovanov in a detailed analysis Monday.

“[TDL-4] is practically indestructible,” Golovanov said.

. . .

TDL-4 infects the MBR, or master boot record, of the PC with a rootkit — malware that hides by subverting the operating system. The master boot record is the first sector — sector 0 — of the hard drive, where code is stored to bootstrap the operating system after the computer’s BIOS does its start-up checks.

Because TDL-4 installs its rootkit on the MBR, it is invisible to both the operating system and more, importantly, security software designed to sniff out malicious code.

But that’s not TDL-4’s secret weapon.

What makes the botnet indestructible is the combination of its advanced encryption and the use of a public peer-to-peer (P2P) network for the instructions issued to the malware by command-and-control (C&C) servers.
