Trivial to make one - you just need a SDR and encryption key (harder to obtain, but probably could be found on the black market).

- lxgr 2y agoYou don’t need any key for GSM, since the network/base station only started authenticating itself to the phone/SIM with 3G. That’s why it would be good to shut down GSM at some point: It would raise the difficulty of such attacks significantly. What I don’t understand is how they managed to actually intercept any SMS with an IMSI catcher. They’d need to get the network to send these through their infrastructure, so I wonder how that worked? Update: Ah, they were just sending out texts themselves, not intercepting anything.
