Lockheed Martin's computer systems are suffering in what is believed to be a cyber attack.
According to Reuters the outfit is grappling with "major internal computer network problems," said one of the sources who was not authorised to publicly discuss the matter. Lockheed is the maker of the stealthy F-22 and F-35 fighter planes and other critical weapons systems.
Lockheed notified the Pentagon about the problem and its response, including resetting passwords for employees, said the defense official, who was not authorized to speak publicly. A spokesman said that the outfit had policies and procedures in place to mitigate the cyber threats to its business, and it was confident in the integrity of our robust, multilayered information systems security.
