Security researchers have said that they have discovered a link between Stuxnet worm and the recently identified Flame malware, both active in the middle east region.

The similarieis indicate that both the teams collaborated to create the programmes. Security experts have begun analyzing new extensive, data-mining computer virus called, Flame. The researchers have found some clues point to its creators and they believe that Flame was written by a different group of programmers than others who have created other virus targeting users in the Middle East.

There are indications that Flame might be part of a campaign that spied on and sent back valuable information. The campaign was a huge set back to the country's nuclear program in 2010, when a large number of Iran's nuclear centrifuges were destroyed in a digital attack.

According to researchers, the virus has several similarities with two other major programs that were used to target Iran in recent years. The first virus, Duqu was used to copy blueprints of Iran's nuclear program and the second, Stuxnet, was designed to attack industrial control systems and spin the centrifuges out of control.
