In mid-March security vendor RSA publicly announced that hackers had successfully compromised parts of their network and extracted information relating to their SecurID products.

Our investigation has led us to believe that the attack is in the category of an Advanced Persistent Threat (APT). Our investigation also revealed that the attack resulted in certain information being extracted from RSA’s systems. Some of that information is specifically related to RSA’s SecurID two-factor authentication products.

RSA SecurID is widely used to provide two-factor authentication of Exchange OWA, Citrix, VPNs, and other corporate remote access.  If you use SecurID products it would be wise to keep up to date with this story as it develops.

How many of the company’s customers will replace them with competitors’ tokens. Probably a bunch. Hence, it’s in RSA’s best interest for their customers to forget this incident as quickly as possible.
