i suppose what he means is that the phones of protestors which have signal chat will be investigated. Assuming they dont have disappearing messages activated, and assuming any protestors willingly unlock their phones.

Feds and ICE are using Palantir ELITE.
That’s only for targeting. From what I understand ELITE does not include device compromise or eavesdropping. If feds want to compromise a device that has Signal, they would use something like Pegasus that uses exploits to deliver a spyware package, likely through SMS, Whatsapp, or spear phishing URL. (I don’t actually know which software is currently in use but it would be similar to Pegasus.)
As mentioned by someone else, they just need to take the phone of a demonstrator to access their signal groups.

Re: FBI is investigating Minnesota Signal chats tracking ICE
#123I don't know signal very well but when I have spoken to others about it they mention that the phone number is the only metadata they will have access to. This seems like a good example of that being enough metadata to be a big problem.
Presumably this is data taken from interdicted phones of people in the groups, not, like, a traffic-analytic attack on Signal itself.
I wonder whether the protesters could opt for offshore alternatives that don't require exposing their phone number to a company that could be compelled to reveal it by US law. For example, there is Threema[1], a Swiss option priced at 5 euros one-time. It is interesting on Android as you can pay anonymously[2], therefore it doesn't depend on Google Play and its services (they offer Threema Push services of their own.) If your threat model includes traffic analysis, likely none of it would make much difference as far as US state-side sigint product line is concerned, but with Threema a determined party might as well get a chance! Arguably, the US protest organisers must be prepared for the situation to escalate, and adjust their security model accordingly: GrapheneOS, Mullvad subscription with DAITA countermeasures, Threema for Android, pay for everything with Monero?

> willingly unlock their phones Or they are running any mainstream iPhone or Android phone, they've unlocked the phone at least once since their last reboot, and the police have access to graykey. Not sure what the current state of things is, since we rely on leaked documents, but my take-away from the 2024 leaks was GrapheneOS Before First Unlock (BFU) is the only defense.
>is the only defense.
Or you know, the 2nd amendment.
Id be willing to bet that ICE would have a much smaller impact if they would be met with bullets instead of cameras. In the end, what ICE is doing doesn't really matter to Trump, as long as MAGA believes that things are being done, even if nothing is being done, he doesn't care.

Federal felony, not free speech.

The steps to trouble: - identify who owns the number - compel that person to give unlocked phone - government can read messages of _all_ people in group chat not just that person Corollary: Disappearing messages severely limits what can be read
Unless they compel people at gunpoint (which prevents the government from bringing a case), they will probably not have much luck with this. As soon as a user sets up a passcode or other lock on their phone, it is beyond the ability of even most parts of the US government to look inside. It's much more likely that the government convinces one member of the group chat to turn on the other members and give up their pho…
Or just let the guy to enter the country after unlocking her phone.

They're "investigating", presumably with data gleaned from arrests and CIs; you have a right to speech, and a right not to be prosecuted for speech, but a much, much narrower right not to be "investigated", collapsing to ~epsilon when the investigation involves data the FBI already has.
No. According to the latest reports, while searching for ICE vehicles, the protesters are unlawfully scanning license plates, which strongly suggests they are receiving insider help.
Can you rule out the much less technically advanced explanation that this information was crowdsourced? And people are simply observing the license plates that are plainly displayed?
Frankly I don’t think it should have to come to license plate numbers. In a free society law enforcement should clearly identify themselves as such. We should not need secret police.

#129I’d be curious to know what they plan to charge people with.
