WorldLeaks is a cyber threat group that emerged in January 2025 as a rebranding of Hunters International, focusing on a pure data extortion model instead of traditional ransomware. They have developed a comprehensive Extortion-as-a-Service (EaaS) platform that aids affiliates in data theft, adopting sophisticated techniques to evade detection and exert pressure on victims through reputational damage.
