Chronus Mafia is a Latin America-focused hacktivist threat actor formed in March 2026 through the merger of Chronus Team and Mexican Mafia Team. The group emerged from the expansion of Chronus Team, a hacktivist collective that appeared in late 2025 and targeted institutions across Mexico and other Latin American countries, including Argentina, Brazil, and Bolivia. Chronus Team publicly claimed data leaks affecting organizations in the education, insurance, law enforcement, healthcare, and government sectors, and used web defacements and Telegram-based leak operations as part of its activity. The merger into Chronus Mafia marked an expansion of operational scope. Available reporting characterizes the actor as part of Mexico’s hacktivist ecosystem, where political and financial motives can overlap. High-confidence activity associated with the group centers on intrusion-related data theft and public disclosure operations against public-sector and civilian institutions rather than ransomware deployment.
