Pro tip: many that ship with an SD inside will have the factory firmware and device-specific keys still recoverable on the card (secure erase is too slow for production I guess) so before turning the device on for the first time, remove the card and image it for maximum chance of recovering the FW intact.




You can detect them with older mobile hotspots with a chip capable of promiscuous mode. Right now mine’s just a canary, a heads up that someone is operating an IMSI catcher nearby, but if ICE is active in your neighborhood having something like that but with more range could be useful for community early warning networks.
