Tomorrow we will present a review talk about the state of mobile network security. The talk will be held at the Linuxwochen in Eisenstadt. We will address results discussed in the past DeepSec conferences (including work of Karsten Nohl, Harald Welte, David A. Burgess, Sylvain Munaut, Dieter Spaar, Ralph-Philipp Weinmann and others). If you understand German we recommend listening to Chaosradio Express #179 where Karsten explain to Tim Pritlove the state of GSM security over a period of 130 minutes. Slides of our talk will be available after the Linuxwochen.
