IMSI Catcher Counter-Surveillance Freddy Martinez This talk will address how activists can detect IMSI Catchers around political protests and how to do some practical counter-surveillance. We will very briefly discuss the capabilities of IMSI catchers and then launch into a discussion about detection and evasion. In the talk we will describe practical (cheap / off the shelf) solutions that we have actually used in various scenarios. Lastly we will describe future work in this area.
