I asked claude how ICE was able to intercept signal chats and it seems like it wasn't a failing of signal's encryption, but rather there were some semipublic signal chats that agents were able to join.

And once they joined these signal chats, they launched a privilege escalation attack - in claude's words:

> In one case, an activist posted a license-plate lookup tool, hosted on Fly.io, to an infiltrated chat. Agents then got the service’s DNS queries, Stripe data, SSH logs, and the signup IP, and matched them with DMV records and Thomson Reuters CLEAR data to find a driver’s license number and other personal records. This was reportedly done by buying data from a commercial broker rather than getting a warrant.
