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. It was not immediately clear what kind of data, if any, was stolen by the hackers. The networks contain sensitive data on future weapons systems as well as military technology currently used in battles in Iraq and Afghanistan.
