New Article for the DeepSec Proceedings Publication

René Pfeiffer/ November 15, 2014/ Conference, Security

In cooperation with the Magdeburger Institut für Sicherheitsforschung (MIS) we publish selected articles covering topics of past DeepSec conferences. The publication offers an in-depth description which extend the conference presentation and includes a follow-up with updated information. Latest addition is Marco Lancini’s article titled Social Authentication: Vulnerabilities, Mitigations, and Redesign.

High-value services have introduced two-factor authentication to prevent adversaries from compromising accounts using stolen credentials. Facebook has recently released a two-factor authentication mechanism, referred to as Social Authentication (SA). We designed and implemented an automated system able to break the SA, to demonstrate the feasibility of carrying out large-scale attacks against social authentication with minimal effort on behalf of an attacker. We then revisited the SA concept and propose reSA, a two-factor authentication scheme that can be easily solved by humans but is robust against face-recognition software.

The MIS web site has a collection of all published articles. The full articles will be found in the special edition „In Depth Security – Proceedings of the DeepSec Conferences“.
