U.S. blamed for spying on French government with Flame malware
Those hackers then crafted a bogus yet effectively indistinguishable clone of Elysee Palace's website and sent phishing emails to lure Sarkozy's advisers into logging on. When Sarkozy's trusted cohorts attempted to log on to the fake page, hackers recorded their passwords and subsequently used them to access the real palace website.
The hackers also planted a "powerful worm" on palace computers. According to BBC's information, the worm used to subvert French computers was Flame -- a highly sophisticated bug based on Stuxnet. Flame and Stuxnet are thought to be U.S. government sponsored tools which were used to spy and wreak havoc on Iranian government PCs.
Armed with credentials and malware, hackers were able to obtain "secret notes", plans of strategy and a myriad of sensitive documents. Flame itself is capable of screenshots, audio recordings and much, much more.
Because of Flame's apparent involvement, sources seem to be presuming the attack was led by the U.S. government and not just a random group of hackers.
