Dark Angels is a highly targeted ransomware and data-extortion group that emerged in spring 2022. Rather than using an affiliate-driven model, it orchestrates discreet, high-impact attacks on large organizations—often choosing one Fortune-level victim at a time. The group exfiltrates massive volumes of data (sometimes 10–100 TB), optionally deploys encryption on Windows or ESXi systems, and pressures victims via a Tor-hosted leak platform ("Dunghill Leak"). Their notable incidents include extorting a record $75 million from a Fortune 50 company in 2024 and demanding around $51 million from Johnson Controls. Dark Angels’ operations emphasize stealth and precision over disruption, often avoiding high-profile media exposure and operating with low operational visibility.
