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
