The FBI has issued a warning against “destructive” malware that could be tied to the Sony hack. The agency counsels businesses to be on the lookout for malware that wipes data from infected machines.

The FBI did not confirm whether the warning had anything to do with the Sony attack, but the timing suggests a connection.”]
