Each week an increasing number of Cryptophone customers are becoming aware of disturbing, yet unfortunately not surprising changes to the cellular network in their area.
This screenshot sent in by a customer shows the Cryptophone 500 alerting them to changes in the mobile network. In this case standard network encryption has been turned off. This is often an indication that a rogue base station or “IMSI Catcher” is active in the area.
While this knowledge would be of great to concern to most people, Cryptophone users can rest easy knowing that even in the presence of an ‘active’ attack’s like this, their communications are still completely secure.
