The U.S. Department of Justice and the FBI said on Wednesday that they had taken actions to disable an international botnet of more than two million infected computers that was stealing corporate data. The botnet, which has been linked to a malicious program dubbed coreflood is believed to have been operated out of Russia. The DOJ and FBI will work with Internet service providers to notify victims whose machines have been compromised with the coreflood malware. Owners will be told how to opt out and keep Creflood running if they so desire.
