Not clear if it was message interception or (maybe more likely) Snapchat have their own moderation that can refer outward. The text is not e2e encrypted

Snapchat boast about having a small turnaround for threats that they proactively scan for and forward to law enforcement.

There is no mystery or need for intelligence skullduggery here.

> He suggested one of the chat's other members could have warned the police, but if that were the case, that other member would have to be charged, not Verma This doesn't make sense to me. Why would that other member be charged for reporting a threat?

Because they would have obviously known it was their friend making a joke.

I don't think they could have known for sure it was a joke.

i'm certain that the feds can read my whatsapp. 100% zuck is ratting me out. every message. considering xkeyscore and prism are over 10 years old. can only imagine what things are like now.

especially with the push of whatsapp business, orgs can freely store ur messages to them.

also by relying on the whatsapp metadata (the one where you can export by urself), it should be already good enough for feds agent to locate u.

for the E2E itself, as non crypto guy, seems the open whisper paper implemented on whatsapp alr good enough?

I don't know much about hashing but is it possible five eyes just has a zettabyte-scale rainbow table covering scary words? They could use that to score encrypted messages and act on the scary ones.

I don't see any use for hashing here, and encrypted messages have padding (otherwise you could trivially decrypt simple messages like yes/no)

It's an /assumption/ that British intelligence able to read and flag private Snapchat messages, as the article literally states, "The trial did not make clear how the British services managed to have access to Verma's private messages, the judge stressed."

The truth is, it isn't public knowledge how this unfolded and anything suggesting otherwise is conjecture.

Also, this post doesn't' reflect the article title, "Spanish judge clears British teen of Menorca flight bomb hoax charges".

Strong encryption has properties that make "known plaintext" attacks impossible. You should not be able to tell the message from pure randomness. Breaking End-to-End-Encryption is not impossible but rather far fetched. If they read Snapchat, my bets would not be on broken crypto, but rather a lack thereof.

If we're speculating, a much more likely explanation is that Snapchat moderation teams monitor certain words in certain areas, flagging for example any message containing "bomb" sent from an airport.

This is arguably even creepier than government surveillance, since it implies Snapchat employees are looking at the content of private chats and the user may never know.

So why shouldn't Snapchat (who presumably reported it to the government) be charged for the same offense of reporting a non-threat?

I'm not suggesting they should be, but just following the same logic as your comment.
