[nexa] French government releases in-house IM app to replace WhatsApp and Telegram use

[...] But despite the French government's plans, the app's launch didn't go as planned. On the same day it was released, French security researcher Baptiste Robert found a security flaw in Tchap that would have allowed anyone to register an account and spy on the French government's internal communications. The researcher found that by adding a government email domain on top of his regular email, like so name@domain.com@french-government-domain.com, he could register on the app, even when not being authorized to do so.
