The state-mandated messenger Max, developed by VK and supported by the Kremlin, is preinstalled on all new smartphones in Russia as of September 1, 2025, and is designed to function during internet blackouts. Following WhatsApp's ban in February 2026, officials have promoted Max as a "sovereign" alternative to Western messaging platforms. A reverse-engineering study revealed numerous surveillance features in Max, including VPN detection that restricts access until VPNs are disabled, real-time monitoring of contact lists, NFC control for manipulating the phone's NFC chip, silent message deletion, IP address tracking, a persistent hardware identifier, the creation of fake chats and reviews, and code injection capabilities. The study also found an on-device machine-learning system that detects keywords from audio input and the ability to record microphone audio during calls without user notification. Additionally, Max monitors access to foreign services and compiles sensitive user information into reports sent to analytics channels. The integration of Max is part of Moscow's broader initiative to consolidate internet traffic through state-controlled platforms, even reaching the International Space Station for communication purposes. Critics view the promotion of Max as part of a strategy to establish a "sovereign" communications system, raising concerns about digital privacy and freedom in Russia.
