twitter has been bad for days, tbf. but IMSI catchers can crash your signal. that's hard to detect unless you're somehow logging every base tower you connect to. if you connect to a tower that doesn't exist, you might be surveilled. I'd stay in airplane mode when you can https://twitter.com/heyheatherirene/status/1266496702615347202
IMSI catcher = Stingrays ^
Cops routinely hide the fact that they're using catchers from judges (at DOJ's instruction) so they might not even bother w/ a warrant. If you're in DC, I'd say chances are higher, but if you're at a major protest, there are definitely feds there anyway, whether u see them or not
US marshals used to attach them to cessnas. they were called dirtboxes. can't remember exactly, but i feel like those were military models. i don't know if they work on drones or if they've been used on drones. https://twitter.com/acyberexpert/status/1266514539132022784?s=20
i haven't done any research on stingrays since 2016 and have no idea how they work with newer generation phones so if someone wants to correct me, that's welcome, but point me to a document of some kind
