May 30, 2012, 9:42 PM — Nailing down a timeline for the development of Flame, the new super-cyber spying malware recently found infecting PCs in Iran and other Middle Eastern countries, will be critical to connecting the dots between it, Stuxnet and Duqu, experts said today.
Flame, as the espionage tool has been named, is a massive piece of malware -- 20 to 40 times larger than Stuxnet -- that infiltrates networks, scouts out the digital landscape, then uses a variety of modules to pilfer information.
What researchers are trying to determine is not only how Flame works -- an effort that will take months -- but how it fits with other malware that experts believe targeted Iran, a country at odds with the West over its nuclear program.
In particular, two earlier-discovered threats: Stuxnet, which most have concluded was created to sabotage Iran's uranium-enrichment facilities, and Duqu, an intelligence-gathering tool many believe was used to pinpoint targets for Stuxnet.
"The most interesting thing about Flame is its possible relationship to Stuxnet," said Roel Schouwenberg, a senior researcher with Moscow-based antivirus company Kaspersky Lab. "The timelines [of the two] will play a big part in any analysis."
Liam O Murchu, director of operations for Symantec's security response center, agreed. "The timeline is very important," said O Murchu.
Both Kaspersky and Symantec are busy digging into Flame, and the two companies were instrumental in deciphering Stuxnet two years ago. They're perfectly positioned to draw conclusions about the two pieces of malware, and any connections between the pair.
Although Stuxnet was first discovered by researchers in mid-2010, Symantec traced its first attack to June 2009, with follow-up campaigns launched in March and April 2010.
Duqu, meanwhile, may have been created as early as 2007 or 2008, even though evidence of attacks by the malware can be tracked only as far back as August 2011.
So where does Flame fit in?
"We looked at our telemetry, and we see evidence of Flame in 2010," said O Murchu. "But it's very possible it goes back further than that."
Kaspersky could trace Flame back about that far, too.
"We've confirmed it in 2010, but there's some circumstantial evidence that goes back to 2007," said Schouwenberg.
