Here’s a recent example of how security holes in these apps can expose your data to malware and other cyber threats: The Check Point security research team discovered a vulnerability in Facebook’s Messenger (both the online version and the mobile app) that would allow an attacker to modify the contents of someone’s chat history as well as give them the ability to spread malware through the chat service.[…] This vulnerability existed because messages are normally stored on Facebook’s servers, and Facebook could also modify the messages itself if it so desired.One famous example is the Facebook messaging app, which sparked a storm of controversy over all the permissions the app asked for upon installation.Since Facebook’s entire business model is built on selling your data to advertisers, why wouldn’t they try to harvest as much of it as they could with a new app?They collect everything they can from anyone they can, from phones all over the globe.Just by analyzing your text messages, they can extrapolate who you’re talking to, how often and about what, your location at any given time, and even glean information about your financial transactions.This is a highly unlikely scenario in the wild, though it is certainly possible under more controlled conditions.Quarks Lab reiterated the “strong requirements” required on multiple occasions.

You may think you’re sharing data confidentially when using Facebook Messenger, Skype or Snapchat, but sometimes it’s just an illusion.Messaging apps also offer the option to be used for both online IMs and SMSs. Without end-to-end encryption, your conversations are right in the crosshairs of cyber criminals, government meddling and amoral marketers.I'm still skeptical because it's closed source, so I would love it if TDesktop would get secret chat ASAP, it would stop me from switching, and allow me to convince my friends to use TDesktop instead of the Russian-made closed source app. It's the main purpose of all project "Telegram" – privacy. I would prefer to discuss a plan instead of forking and doing my own thing.
