Cell-Site Simulators (a.k.a. Stingrays or IMSI
-catchers) let their operators perform Surveillance
on the Mobile Device
- IMSI-catcher - simply record nearby IMSIs, and then don’t interact with their target phones in a significant way beyond that.
- Communication interception (Man-In-The-Middle) between a Mobile Device and a legitimate CELLID tower is only possible in GSM (G2) (as opposed to later 3G or 4G protocols as communicating over GSM doesn’t always require encryption and even when encryption is enabled, several of the cryptographic algorithms used in GSM can be broken (and in real time).
Cell-Site Simulatorss are used by Attackers, Law Enforcement Agency and Government Surveillance
