Lockheed Martin has “major internal computer network problems,” that one security blogger is linking to compromised RSA tokens, according to published reports.
Use of the company network is disrupted, but a Lockheed spokesperson wouldn’t talk about the problem directly as a matter of policy, according to a Reuters story. The report was based on two sources, one of whom termed the incident to be major and the other who said it was “affecting a lot of people.”
Security consultant Robert Cringely says that a major defence contractor is issuing new RSA SecurID to all employees using them for remote access, and he confirmed in a phone call that the contractor is Lockheed. RSA revealed March 17 that its network was breached and it is believed algorithms used to generate SecurID passwords were stolen.
Remote access at Lockheed will be down at least until Sunday, and in the meantime telecommuters have been asked to work from corporate offices near their homes, Cringely says.
Cringeley’s analysis of the problem is that someone managed to install a keylogger on a machine that had access to the Lockheed network, grabbed passwords and has combined the passwords with knowledge of RSA algorithms used to generate access codes used in SecurID two factor authentication tokens.
He says that after RSA’s network was breached earlier this year, Lockheed required an extra password for remote access, but that a keylogger would get around this extra layer of protection.
Lockheed has a great deal of sensitive and valuable intellectual property that would make it worthwhile for an attacker to target the network, such as plans for stealth fighter jets.
But attackers also use compromised contractor networks as a way in to government networks since the contractors likely have links to carry on business, said Brian Contoas, Director Global Security Strategy, for McAfee.
Lockheed responded to questions about the incident with this written statement: "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," said spokesman Jeffery Adams.
