NetworkWorld: Published reports say that Lockheed Martin is experiencing major internal computer network problems. The problems are thought to be related to compromised RSA tokens. The company has shut down remote access (which requires an RSA SecurID token) and is issuing new tokens.
Lockheed Martin's networks have a wide variety of sensitive and valuable information, including the plans for fighter jets. Hackers could also be attempting to use the network as a way in to government IT systems.
