I've spent not-insignificant amount of time at protests in the US, looking for signs of IMSI catchers and never found anything, so when I saw this, my ears perked up:

Imagine my horror when I got a support request: "the attached logs don't look right to us - can you tell us what's going on please?" with the footnote "this was from field testing in a shopping centre in Slough."
I knew there was a reason i kept taking my phona faraday cage along.
Reasons why I told people not to bring phones with them when they protest.
Digital Cameras, yes, but not phones.

In 3G+ standards the network must authenticate back to the SIM, a feature specifically designed to make this attack much more difficult. Have US carriers just given up the crown jewels crypto keys to their networks?
Note that network operations that involve requesting IMSI from the device are a legitimate part of the operation of the network. Bursts of authentication-related signalling might simply be a symptom of a locally congested site.
I long for the day of a simple digital camera.
There is just too much to telemetry. It doesn’t help that Ripple (the company) and Horowitz have donated the money to police departments for surveillance drones and an operation center.
We don’t need the world’s wealthiest men provisioning police forces. It should be seen as a very bad optics.
If only because crypto is so heavily enmeshed with international crime and we’re talking things like human trafficking.

BLM protest in downtown Palo Alto, number of years ago.
I strolled past, noted an unmarked van with a lot of stubby antennas on top, door cracked open, dude inside minding a rack of electronics. I assumed it was a ISMI catcher or a stingray thing.
Speaking as a member, is there a role for EFF in raising awareness of this?
