NEW: Spanish police identified a pro-Catalan independence activist thanks to legal requests to Apple, and encrypted services Wire and Protonmail, according to court documents we obtained.
Spanish authorities used legal requests that listed "terrorism" as the nature of the investigation.
This story shows that using apps that encrypt content won't save you if there's personal info in the metadata.
@lorenzofb If the activist had used Signal, the police would have needed only a single step - to obtain his phone number, from where they would have trivially identified him. Unless it was a burner, but that's pretty much impossible in Europe.
