Which discusses how Telegram was banned in many countries for refusing cooperation while WhatsApp suspiciously was never banned, which could mean that WhatsApp gives governments everything they demand.
WhatsApp had perfectly usable encrypted backup - which took up space on your Google backup. And then, all of a sudden, it wasn't encrypted and didn't take up space. But you don't have access to it yourself - only Google does (and WhatsApp if it is recovering). This is a perfect way to provide all the data to various governments for 99.9% of users, without killing the E2E encryption.
WhatsApp backup in iCloud is not encrypted.
Anyways, something like 6 months after launch a Russian guy found that they were seeding their secret chat keys with entropy from the server, meaning the server could trivially MITM any secret chat. Pretty embarrassing.
Iirc it got quite little publicity since most of the discussion was in Russian, and the disclosure was in a forum post in an obscure forum.
You aren’t going to find any cryptographers anywhere who’d be willing to repeat your “They didn’t backdoor it” lie.
If it looks like a backdoor, swims like a backdoor, quacks like a backdoor, then it probably is a backdoor.
FiloSottile described it as “The most backdoor-looking bug I’ve ever seen” https://twitter.com/filosottile/status/987376021589692416?s=...
Do you have any recent bugs? Or 'backdoors'? All their official apps are open source and reproducible. Must be easy to find bugs for security researchers. They even offer much larger bounties compared to other apps.
Anything? I want to believe people saying bad crypto, but it looks like there's no actual proof.
Here's something that says it is good, published more recently.

You might argue that their deliberate decision to not encrypt most chats is exactly that, more of a front door really.
Telegram is a bad actor.
