The article is exaggerating the guy’s setup way too much. Opsec doesn’t end at the application level… The OS (the most popular being in bed with US), ISP, tor nodes, Honeypot VPNs, so on and so on could leave a trail.

Using telegram public groups and obfuscating a calculator as a password protection layer is hillbilly level of security.

And i’m glad these fuckos don’t have the knowledge to go beyond App developers marketing.
