"There is a significant risk of insider threat or hacking of Telegram systems that could expose all of these chats to the Russian government," said Eva Galperin with the Electronic Frontier Foundation, which has called for Telegram to improve its privacy practices. Telegram boasts 500 million users, who share information individually and in groups in relative security. But Telegram's use as a one-way broadcast channel β which followers can join but not reply to β means content from inauthentic accounts can easily reach large, captive and eager audiences. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. In 2014, Pavel Durov fled the country after allies of the Kremlin took control of the social networking site most know just as VK. Russia's intelligence agency had asked Durov to turn over the data of anti-Kremlin protesters. Durov refused to do so. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means itβs less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isnβt as secure earned it some criticism. If youβre looking for something that is considered more reliable by privacy advocates, then Signal is the EFFβs preferred platform, although that too is not without some caveats.
