These applications should be treated as Trojan horses. If they aren’t open source and you are a journalist/dissident or anyone targeted by nation states you have got to assume your WhatsApp/Facebook is being used to compromise your device.

Being open source doesn't actually save you from exploitable vulns related to integer arithmetic.

Since the issue was in both the iOS and Android versions of the app, and it was caused by an integer overflow, does that mean that the bug was in a bundled C++ library implementing webRTC? Is there any information about the source-level cause of the issue?

Notably on iOS there's no good way to isolate unsafe native libraries from the rest of your app without violating app store policies, because Apple enforces apps to be single process and doesn't allow use of its own sandboxing apis.

You have to understand, they enforce those rules for security reasons. /s

On this subject, I like to quote Pavel Durov, the founder of Telegram: "Since the creation of WhatsApp, there's hardly been a moment in which it was secure: every few months researchers uncover a new security issue in the app. I wrote about this in detail 2 years ago (read here if you missed it). Nothing has changed since then. It would be hard to believe that the technical team of WhatsApp is so consistently incompe…

Telegram implements video calling using bunch of sketchy C code same as WhatsApp and Signal. There's no reason to think it's less vulnerable these sort of bugs.

I wonder if someone more informed could help me understand Telegram's business model, as I don't think I could rightly describe the startup and product in a way that wouldn't sound like I was casting aspersions. Why would anyone use Telegram over something end to end encrypted, like Signal, Matrix, WhatsApp, Facebook Messenger, etc.?

It has features that regular users really, really like. Not having to associate the account with a phone number, scheduled messages, groups/channels with thousands of users, the ability to program bots, silent messages, editable messages, ...

Some people care more about these than security or privacy. It's that simple.

As for monetization, I believe they have premium stickers and such.

It saves you from obviously planted ones that can be found by code scanners.

if you can't trust Meta, why could you trust apple?

Apple has been building their brand on privacy and trust for at least a couple of years now. Can you be sure they're not sending everything to the NSA? Of course not. But they also make their money by directly charging users for services unlike the ad-based companies. There have also been many attempts by various governments to publicly force Apple to insert backdoors or prevent them from fixing security vulnerabilit…

Why would I think there is any truth in something apple's marketing department is saying?

«The Russian government hates him too.» Telegram is one of few popular messengers that are NOT blocked/prohibited in Russia. So government and Durov have some agreement.

«The Russian government hates him too.» Telegram is one of few popular messengers that are NOT blocked/prohibited in Russia. So government and Durov have some agreement.

Russia’s main security agency, the FSB (a successor to the KGB) has branded Telegram the messenger of choice for “international terrorist organizations in Russia.”

The government’s first attempts to ban it, a year ago, resulted in entire sections of the web, online stores, services—even the Kremlin museum’s ticket sales—being inadvertently blocked. But the messaging app has adopted a clever system of changing IP addresses that currently outsmarts the government ban.

Meanwhile, users have continued to access Telegram through VPNs, or virtual private networks, which have become increasingly popular.

It is difficult or impossible to block Telegram in Russia.
