RSA breach leaks data for hacking SecurID tokens

'Extremely sophisicated' attack targets 2-factor auth

Attackers breached the servers of RSA and stole information that could be used to compromise the security of two-factor authentication tokens used by 40 million employees to access sensitive corporate and government networks, the company said late Thursday.

"Our investigation has led us to believe that the attack is in the category of an Advanced Persistent Threat (APT)," RSA Executive Chairman Art Coviello said in an undated letter posted on the company's website. "Our investigation also revealed that the attack resulted in certain information being extracted from RSA's systems."

Neither the letter nor a filing (PDF) with the Securities and Exchange Commission identified what the stolen data was, but Coviello went on to say it "could potentially be used to reduce the effectiveness of a current two-factor authentication implementation as part of a broader attack."
