Defence contractor Lockheed Martin is experiencing a major disruption to its computer systems that could be related to a problem with network security.
According to Reuters, Lockheed is grappling with ‘major internal computer network problems', according to a source while another source said that the issue was ‘affecting a lot of people' at the company.
Blogger Robert Cringely initially detected a slowdown from Sunday after security experts for the company detected a network intrusion. Cringley also said that the intrusion involved the use of SecurID tokens that employees use to access Lockheed's internal network from outside its firewall.
A spokesman for EMC whose RSA division makes the tokens, declined to comment, saying it is company policy to never discuss security issues affecting specific customers. RSA was hit by an advanced persistent threat in March, executive chairman Art Coviello said that ‘certain information' was extracted from RSA's systems, some of which was specifically related to RSA's SecurID two-factor authentication products.
Lockheed Martin spokesperson Jeffery Adams, said: “We have policies and procedures in place to mitigate the cyber threats to our business and we remain confident in the integrity of our robust, multilayered information systems security.”
Michael Everall, CISO at Lehman Brothers Holdings, said: “Based on the facts, this has all the hallmarks of a serious breach, which was probably developed over a period of time and if it is linked to SecureID, it was probably specifically targeted as part of the RSA breach.”
