every now and then i see somebody claiming to know more and hinting at deeper things going on with mobile modems, basebands, gsm.

then they can‘t say anything because of nda. or the gsm standard manual costs hundreds of dollars.

my tin foil hat is glowing, i‘m telling you. we already know that gsm encryption is a joke. i don‘t want to imagine what‘s going on inside all those closed-source baseband firmwares. it creeps me out.
