University of Washington actually has a neat project where they drove around Seattle and Milwaukee to try and do International Mobile Subscriber Identity (IMSI)-Interceptor detection. Basically, find cars or buildings with mobile towers that intercept and redirect your cell signal through a man-in-the-middle observation. [2] Notably, United States Citizenship and Immigration Services building (USCIS) apparently operates one. The pictures are rather pretty.

- ajcp 3y ago> To covertly transmit on the same frequencies as the normal cellular network, IMSI-catchers may mimic the identifying properties (mcc, mnc, cell id, etc.) of legitimate cell towers. [2] How is this not illegal?
- BobaFloutist 3y agoBecause it's largely being done by law enforcement.
- Tostino 3y agoDoesn't mean it's not illegal, just that they won't punish themselves.
- ahazred8ta 3y agoSome of those may not actually be law-enforcement IMSI interceptors. Some government buildings have legitimate microcell antennas that are installed and operated by the telco. https://en.wikipedia.org/wiki/Microcell https://en.wikipedia.org/wiki/Microcell
