BOSTON/WASHINGTON (Reuters) - Unknown hackers have broken into the security networks of Lockheed Martin Corp and several other U.S. military contractors, a source with direct knowledge of the attacks told Reuters.
They breached security systems designed to keep out intruders by creating duplicates to ``SecurID'' electronic keys from EMC Corp's RSA security division, said the person who was not authorized to publicly discuss the matter.
