RSA Security probably hoped the issue of compromised SecurID tokens would just get swept under the rug and quietly disappear. No such luck.
Following recent attacks against Lockheed-Martin and other defense contractors, which used counterfeit SecurID keys to attempt to gain unauthorized access to the network, RSA Security has had to admit the scope of the problem and offer to replace the compromised SecurID tokens, and offer some additional perks as well to try and earn back some customer trust.
There are roughly 40 million SecurID tokens in circulation. Replacing them will not be cheap, but rebuilding customer confidence is much more important than the short term financial impact.
