SchoolBoys Ransomware is a ransomware and data-extortion brand associated with a Russia-linked cybercrime ecosystem tied to former Conti members and overlapping with operations conducted under names including Karakurt, Royal, TommyLeaks, and Akira. Available reporting links the brand to an organization active from roughly 2021 through 2023 that targeted dozens of victim organizations, including businesses, government entities, and a pediatric healthcare provider, with many known victims in North America and others in Europe. The organization conducted intrusions primarily through abuse of stolen VPN credentials, followed by post-compromise activity using common offensive and administrative tooling for remote access, credential theft, scripting, compression, and bulk data transfer. Its operations emphasized theft of sensitive data and extortion through threats to leak or sell that data, including pressure tactics built around personal and health information. This tradecraft aligns strongly with data-theft extortion rather than encryption-centric ransomware activity. Reported impacts include major financial losses across more than 54 victim organizations and disruption affecting a U.S. emergency dispatch environment. The SchoolBoys Ransomware brand appears to have been one of several labels used by the same broader criminal organization rather than a clearly distinct standalone group. High-confidence attribution in public legal reporting connects this ecosystem to Russian ransomware actors and former Conti leadership.
