It would be trivial to discover and would be pretty big news in the security community.
I'd wager most of these comments are from nontechnical people, or technical people that are very far removed from security.
I don't see why standard RE techniques (DBI/Frida + MITM) wouldn't work, do you?
WhatsApp is constantly RE'd because it'd be incredibly valuable to discover gaps in its security posture, the community would find any exfil here.
We did reverse engineer it and we're cryptographers not reverse engineering experts https://eprint.iacr.org/2025/794
If people are trivially hooking IOS and Android applications then sure, it's just an exercise in dynamic analysis.
Mobile applications are outside my domain so I am surprised platform security (SEL, attestation, etc.) has been so easily defeated.
I'm technical and work in security. Since it is trivial, please explain. Ideally not using a strawman like "well just run strings and look for uploadPlaintextChatsToServer()".
