While your point stands, this whole thing is bullshit. The photo of the car interior is a stock image and all the "data" they supposedly gathered was actually just the names of local DSA members from their social media and their friends' accounts (which is alarming for a whole lot of other reasons).
They really put you in a list for having a fucking rose in your twitter handle? Then fuck it, imma put a rainbow and a thunderbolt
Or maybe you do are a cop and want to discourage us from massively register as DSA and score 0.5% votes in the next election
Literally just dont bring your phone.
Don't turn it off
Don't put it on airplane mode
Unless you're a designated comms officer who needs a phone leave it behind.
there had been more than fifty arrests of demonstrators as we left the square. The IMSI catchers had conducted a census of all the phones in the neighborhood that night and the back-end had opened tickets with the Ministry of Communications to pull all the calling records to produce a social graph and mark out highly connected nodes, then run an information-cascade analysis: that was a cute machine-learning trick that tried to identify leaders - formal or informal - by looking at people whose communications produced "cascades" of activity: Alice calls Bob, who then calls Carol and Dan and Eve and Faith, so Alice is the boss and Bob is her lieutenant

Leave your shit on and at home, folks. When the pigs go to look up where you've been, they will find the record of a very boring person who doesn't know anything.
In this situation, they wouldn't know anything about you, because your phone wouldn't be connecting to the IMSI.
In the event that you really need to use a comms device, use a walkie talkie, or a burner Android with an IMSI catcher detector installed. Send all your communications through encrypted chat clients.
Read the faq in that link. They are meant to prevent your phone from sending data when connected to a Singray/Femto cell.
There are multiple methods, this one is trying to build a database of all legitimate cell towers and their id#. So whenever you connect to a new cell, it cross referenced the cell id with the database to see if it's legit or a stingray. Then it will warn you/auto disconnect you before you send anything incriminating. This one's neat because it lets you manually manage cell tower connections and actually check the map to see exactly where the tower your phone is connected to physically is.
I misspoke in the original post btw, this is an imsi catcher detector. An IMSI catcher is just a fake cell tower that cops/feds/hackers/etc use to man in the middle your phone. It's ARP spoofing on a much larger scale. Also gives them power to do things to your phone that only your service provider is supposed to be able to do, like push out OTA updates and install apps.
That's really cool, thank you!
Could two or more people use this to triangulate the location of a Stingray?
Hypothetically? I haven't really used it much. You'd have to read the raw data and determine it from the signal strength. Which would be hard seeing as how both people and the vehicle carrying the stingray would likely be in motion. It would warn you that a Sting Ray is nearby and you could just warn people to be on the lookout for a van or something. If enough people had it installed and were far enough apart, you could find out the general area and send people to search for it.
What's that "Disruptive" tag right next to their name? A twitter extension?
Airplane mode isn’t enough. Turn it off, turn off biometric unlocking and locked notifications too.
does turning it off even work? been doing that but thinking more and more about just leaving it at home & using prior rendevous for coordination
That’s a fair point and prob depends on brand. Something else might be buying a shield bag to isolate your phone from the network. Not sure if there are transparent options that let you take photos, but otherwise yeah these all lead to just not using it so might as well leave it at home.
