Who is the hacker Cyberleek that leaked Grand Theft Auto VI gameplay and demanded changes from Rockstar?

A hacker identifying as “Cyberleek” has leaked multiple gameplay clips and what appears to be the full map for Grand Theft Auto VI, creating a security incident for Rockstar Games. The breach comes as the game remains scheduled for release on November 19, 2026, a date Rockstar confirmed in a statement released November 6, 2025. Rockstar has not publicly addressed the leaked content. Cyberleek says the action is a protest against anti-consumer practices and demands changes, including removal of digital pre-orders, deleting “fake” single-player DLC already found in game files, and adding mandatory offline fallback modes. The leak follows earlier Rockstar security issues, including a 2023 breach involving Lapsus$.
