The recent hack into the huge defense contractor Lockheed Martin was accomplished using compromised security tokens from a company called RSA Security. The company admitted that yesterday. RSA's SecurID tokens are random password generating devices attached to computers or networks. A lot of companies and government organizations use them. So evidently the problem was that someone used information from RSA to gain access to the tokens. RSA is now offering to either replace or monitor millions of these tokens all over the world.
