The attacks, similar to the ones launched on Lockheed Martin last Sunday (May 22), reportedly occurred in April, and were perpetrated using SecurID keyfobs stolen during a March breach on the keyfobs' manufacturer, security company RSA.

RSA's security keyfobs, which generate a new six- or eight-digit number every 30 or 60 seconds, are used by an estimated 40 million employees to access sensitive computer networks.
