SAN FRANCISCO - Hackers who recently broke into Lockheed Martin's security network used data stolen from an EMC security division and the company offered to replace millions of potentially compromised "SecurID" electronic keys.
Lockheed Martin, the Pentagon's No. 1 arms supplier and the US government's top information technology provider, was attacked last month by hackers, underscoring a growing threat to US national security.
RSA, which makes the SecurID keys, said in a letter published on its website that it has confirmed information taken from it in March was used in the attack on Lockheed Martin.
EMC had previously warned that information stolen from RSA related to its SecurIDs and has now offered to replace the SecurID keys of any customers who ask, a spokesman told Reuters.
