This is objectively false. Reverse engineering is a thing, as is packet inspection.
Reverse engineering is theoretically possible, but often very difficult in practice.
I'm not enough of an expert in cryptography to know for sure if packet inspection would allow you to tell if a ciphertext could be decrypted by a second "back door" key. My gut says it's not possible, but I'd be happy to be proven wrong.
Hell, as far as I know, E2EE would be indistinguishable from client to server encryption, where the server can read everything without the need for a secret "backdoor key". You can see that the channel is encrypted, but you can't know who has the other key.
The easiest way to break E2EE is to copy your private key to Meta's servers. It's very easy to implement, and close to impossible to detect.
Now you just need Meta to allow you on their networks to inspect packets and reverse engineer their servers because as far as I know, WhatsApp messages are not P2P.
/edit I betcha $5 that the connection from client to server is TLS(https), good luck decrypting that to see what its payload is.
No it is not. Whatsapp gets several updates a month. How do you keep up with that rate?
Outside of open-source. That shit is usually illegal
It isn't. Otherwise security research would never happen for proprietary software and services.
In the US, CFAA is so draconian that in certain aspects it can be very illegal to reverse engineer code behind explicit ToS which whatsapp make you agree through click-wrap agreement (meaning explicit I agree button press) upon installing the app. So Meta could easily sue you with very good chance of winning. I work in security and reverse engineer a lot of stuff but just because my company has lawyers that will protect me (also I'm not an american) but generally americans are super fucked here and there are many stories of people being sued and even imprisoned for breaking ToS.
SureSure no white hat never been sued before
