http://cdn-static.zdnet.com/i/r/story/70/00/036313/it-security-v1-620x465.jpg?hash=ZwywZwtmLz&upscale=1The US Federal Bureau of Investigation (FBI) has warned that hackers have used malware to launch destructive attacks against businesses in the United States, following a devastating attack on the networks of Sony Pictures Entertainment.
In a five-page confidential "flash" warning send to businesses late on Monday and seen by Reuters, the FBI provided technical details about the malware, but did mention the corporate victim by name. According to the advisory notice, the malware is particularly violent -- overriding data on hard drives to make them little more than bricks while also closing down networks at the same time.
While it is likely the malware in question is linked to the Sony hack -- considering the timing of the issued warning -- an FBI spokesman declined to comment on the advisory. If this malware has been used in the Sony security breach, the recovery process is likely to be costly and time consuming.

The FBI issued a five-page flash warning yesterday urging American enterprises to be on the lookout for wiper malware.
The alert, a Reuters report said, described some details about the malware but kept the victim anonymous.
 
It’s general practice for the FBI not to name victims in such alerts. The timing of the warning, however, is curious since it follows on the heels of the Sony Pictures breach in which a number of unreleased movies were leaked online and other systems were damaged and kept offline.
