Coinbase Cartel, active since September 2025, specializes in data exfiltration without encryption, claiming 14 victims in its debut month. This Coinbase Cartel extortion strategy pressures organizations via leak threats on dedicated sites, targeting entities with revenues from millions to hundreds of billions.
Healthcare, technology, and transportation represent over half victims, with 10 UAE healthcare facilities attacked in one month suggesting economic motives. Bitdefender lists it among top-10 ransomware groups for September and December 2025.
