Well we did say assume SecurID was broken back in March when we wrote – RSA Silent About Compromise For 7 Days – Assume SecurID Is Broken.
With the recent news Lockheed Martin Hacked – Rumoured To Be Linked to RSA SecurID Breach and another US Military sub-contractor compromised through SecurID tokens – RSA have FINALLY come clean about it.
They basically have to replace all 40 million SecurID tokens out there, imagine how much of a headache that is going to be – and how much is it going to cost? This is going to end up as one hell of a costly hack for RSA.
RSA Security is to replace virtually every one of the 40 million SecurID tokens currently in use as a result of the hacking attack the company disclosed back in March. The EMC subsidiary issued a letter to customers acknowledging that SecurID failed to protect defense contractor Lockheed Martin, which last month reported a hack attempt.
SecurID tokens are used in two-factor authentication systems. Each user account is linked to a token, and each token generates a pseudo-random number that changes periodically, typically every 30 or 60 seconds. To log in, the user enters a username, password, and the number shown on their token. The authentication server knows what number a particular token should be showing, and so uses this number to prove that the user is in possession of their token.
The exact sequence of numbers that a token generates is determined by a secret RSA-developed algorthm, and a seed value used to initialize the token. Each token has a different seed, and it’s this seed that is linked to each user account. If the algorithm and seed are disclosed, the token itself becomes worthless; the numbers can be calculated in just the same way that the authentication server calculates them.
What bothers me, from a cryptography stand-point at least, is that RSA should not know or even be able regenerate the seed and associated token value for their clients.
And along side that, surely SecurID is used as a part of a two or three factor authentication system, so what happened to the other factors in these hacks? Why were they so easily compromised once the hackers could generate the token values?
It just amazes me how these security related companies (with military information) can be so lax on security. Even if the token failed – no one should have been able to get in!
This admission puts paid to RSA’s initial claims that the hack would not allow any “direct attack” on SecurID tokens; wholesale replacement of the tokens can only mean that the tokens currently in the wild do not offer the security that they are supposed to. Sources close to RSA tell Ars that the March breach did indeed result in seeds being compromised. The algorithm is already public knowledge.
As a result, SecurID offered no defense against the hackers that broke into RSA in March. For those hackers, SecurID was rendered equivalent to basic password authentication, with all the vulnerability to keyloggers and password reuse that entails.
RSA Security Chairman Art Coviello said that the reason RSA had not disclosed the full extent of the vulnerability because doing so would have revealed to the hackers how to perform further attacks. RSA’s customers might question this reasoning; the Lockheed Martin incident suggests that the RSA hackers knew what to do anyway—failing to properly disclose the true nature of the attack served only to mislead RSA’s customers about the risks they faced.
I’m fairly sure we’re going to hear more about this, and I wouldn’t be surprised if we start seeing some lawsuits from disgruntled clients of RSA popping up. It seems like RSA went the security through obscurity route – rather than responsible disclosure and letting everyone what was going on.
They thought they could protect against hackers…by not saying anything?
Seriously RSA, is that the best you’ve got? The recent compromises of US military contractors proves that that tactic didn’t work at all (unsurprisingly).
