Thinking aloud in terms of a "solution" - is it possible to build crowdsourced blocklists that can be subscribed to by users, and will refuse to let their phones connect to "fake" celltowers?

P.S. I'm not a wireless guy, so I don't know if there's any kind of a digital giveaway that can distinguish a fake cell tower versus the real one it is spoofing. If there isn't, then perhaps the fault lies with existing wireless comm. standards.

Not until the baseband processor is proprietary. And even then nothing prevents feds from just giving the towers new ids or just manipulating the blacklists.

The solution is to make it illegal and/or enforce it as such.
