World's most complex malware discovered

Researchers from several security companies have discovered a new, highly sophisticated malware threat that was predominantly used in cyber espionage attacks against targets in the Middle East. The malware is called Flamer and might be responsible for recent data loss incidents in Iran.

Cyber-security experts say the bug's complexity indicates it is the work of a government - not rogue hackers.

"I think it would hard to say that anyone other than a nation state would be behind it," Orla Cox of Symantec Security Response told the Huffington Post. "You're looking at a well organised well funded group."

"Based on collateral data, we can be sure that Flame was out in the wild as early as in February to March 2010," says Kaspersky's head of global research and analysis Alexander Gostev. "It’s possible that before then there existed earlier version, but we don’t have data to confirm this; however, the likelihood is extremely high."

Warning of its potentially crippling significance, Kaspersky compared the threat to famous cyber worms Duqu and Stuxnet, created to target an Iranian nuclear facility.
