On Facebook’s social authentication

Tuesday, February 15th, 2011

Recently Facebook added security controls to protect its users against unauthorised access:

It was about time to employ SSL in order to protect the passwords, but the use of “social authentication” creates a false sense of security:

1. CAPTCHA are supposed to distinguish between a machine and a human, not a hacker and a human. Perhaps we should emphasize that hackers are human! Watch out Facebook, you will get Greenpeace on your tail, hackers are not animals :-p

2. The complexity of breaking the social CAPTCHA is linear, or at least it is definitely not exponential. Following point 1 above, a human hacker maintains enough cognitive skills to gather enough information to “break” the challenge. Besides, the person’s characteristics, ethnic background traits etc. form a side channel that help us eliminate some answers (for example from the pictures below the person is less likely to be Nick Wilkerson, Tim Kuper, David Starling) and the probability distribution is not uniform.

USB attack vectors: Can they be thwarted by disabling autorun?

The answer is no.

In our work “On the detection of pod slurping attacks” we raised the security issues by having autorun enabled in Windows, but we underestimated the 0-day attack incorporated in stuxnet malware:

- Number of Internet users in 2010: 2 billion (approx., Internet World Stats)

- What percentage of the above users are security aware? 1%? 5%? 30%? FIFTY % ? (doubt it). There still remains at least ONE BILLION security illiterate users (citizens). Lots of opportunities for exploitation, unfortunately…

So how about a framework with a primary goal to exploit the user’s security unawareness? Well, here is is:
