Stuxnet, Duqu Date Back To 2007, Researcher Says

Two pieces of malware likely were developed by the same team on the same platform along with similar variants, according to Kaspersky Lab.

The origins of the dangerous Stuxnet computer virus that targeted Iran's nuclear power program last year could date back as far as 2007, according to new research. Researchers have dubbed the platform "Tilded" because its authors tend to use file names which start with "~d," said Alexander Gostav, head of Kapersky's Global Research and Analysis Team, in a blog post

Stuxnet and the related Duqu virus discovered earlier this year share a similar architecture and may have been developed by the same team of developers--along with other pieces of malware--several years ago, according to a security researcher at Kapersky Lab.

"There were a number of projects involving programs based on the 'Tilded' platform throughout the period 2007-2011," Gostav said. "Stuxnet and Duqu are two of them--there could have been others, which for now remain unknown."

Researchers discovered the connections between the pieces of malware and their origins by examining their drivers, he said.

Gostav warned that the Tilded platform is continuing to develop and more modifications of the viruses are likely to be a threat in the future.

Stuxnet was first discovered in June 2010 when it attacked software and equipment used by various organizations facilitating and overseeing Iran's nuclear program.

The virus was especially worrisome for researchers because of its unprecedented complexity; it contains more than 4,000 functions, which is comparable to the code in some commercial software.

Researchers at the Budapest University of Technology and Economics' CrySyS lab discovered Duqu this past September, saying the malware appears to have been designed to steal industrial control design documents.

After examining Duqu, researchers at Symantec said it was nearly identical to Stuxnet. Both viruses attack Microsoft Windows systems using a zero-day vulnerability, which tries to exploit application vulnerabilities that haven't been discovered yet.

Superworms like Stuxnet and Duqu--which seem to have been created to target the critical infrastructure and control systems of particular countries--are of great concern for federal cybersecurity officials who are working to prevent such dangerous threats to the U.S. power grid and other essential facilities.
