Lockheed had to locked down its network after it was massively hacked:

By all accounts, Lockheed Martin’s swift detection of the attack helped avert potential disaster. “The good news here is that the contractor was able to detect an intrusion then did the right things to deal with it,” Cringely said. “A breach like this is very subtle and not easy to spot.” Furthermore, he said, the same day that Lockheed Martin detected the attack, all remote access for employees was disabled, and the company told all telecommuters to work from company offices for at least a week. Then on Wednesday, the company informed all remote workers that they’d receive new RSA SecurID tokens and told all 133,000 employees to reset their network passwords.

In a statement released Sunday, EMC said it was “premature to speculate” on the details of the attack. But if attackers did use information stolen from RSA to hack into the SecurID system used by Lockheed Martin, then EMC could be forced to finally reveal, publicly, any risks that the use of its system might now pose to the 40 million users of SecurID hardware token customers and 250 million users of its SecurID software.

I’m a contractor, so even if my employer were hacked in this manner, it would not effect me, since that don’t give mercenaries like me remote access to their networks.

Of course, they should have locked down their system months ago, when RSA, the company that supplies the keys for their VPN systems, and a lot of other companies out there, was hacked.
