404 Media has obtained the list of sites and services that ICE contractor ShadowDragon pulls data from. ShadowDragon sources data from all over the web and lets government analysts easily search it and draw connections between people.
Probably just whatever the public metadata is. metadata is super powerful especially if you have a lot of it. if the email was protonmail to protonmail they will get nothing. If it’s gmail to protonmail they will know that user X is talking to User Y in gmail. They will also have the email header information which is basically just going to be clear text. so they can still ascertain who you know, who you are talking about, and maybe a bit about what the conversation has to do with.
EDIT: so I asked protonmail directly about it and they confirmed its only publicly available information that they can get. For instance they can try and verify if a certain email address exists. However proton told me that they actively watch for this kind of thing and block IPS trying to do this sort of monitoring.
What are they gonna do? Download gibberish?! Lol, it’s all end-to-end encrypted with the decryption keys stored locally.
Edit: See below comment by @[email protected]. Shit’s still concerning.
