Anubis is a ransomware-as-a-service operation that emerged in late 2024 and has also been described as a rebrand of Sphinx. The group conducts double-extortion intrusions that combine file encryption with data theft and operates a public leak site to pressure victims. Reporting also attributes an optional destructive file-wiping capability to the operation, increasing the risk of irreversible data loss even after incident response begins. Known aliases include Anubis RaaS, Anubis ransomware group, and Anubis ransomware operation. Anubis has targeted organizations across multiple industries, including health care, financial services, retail, consumer-facing businesses, and food production/manufacturing. Victims publicly associated with the group include organizations in the United States, France, and the United Kingdom, and the operation has been described as targeting organizations worldwide. In the Fairlife incident, Anubis claimed responsibility for a ransomware attack that disrupted U.S. production operations, asserted that it had encrypted infrastructure and stolen corporate data, and used its leak site to threaten publication before later releasing allegedly stolen data after negotiations failed. The group’s observed tradecraft is consistent with modern extortion-focused ransomware operations: compromise of victim environments, encryption of systems, exfiltration of data for coercion, operation of a leak site, and aggressive ransom pressure tied to publication deadlines. Available reporting supports Anubis as a financially motivated criminal enterprise rather than a state-directed espionage actor.
