About the Anubis group

Anubis is a ransomware-as-a-service group active since December 2024 that targets healthcare, engineering, construction, and professional services sectors, offering affiliates a flexible revenue split model and an optional destructive "wipe mode" alongside standard encryption.

Incident Analysis

AllerVie Health was targeted by Anubis ransomware, one of the most active ransomware groups in our database with 106 confirmed victims globally. The attack was disclosed on November 26, 2025, when AllerVie Health appeared on the group's dark web leak site.

AllerVie Health is based in United States , operating in the Healthcare sector. United States ranks #1 globally for ransomware attacks, with 9,192 victims in our database.

Sector context: Healthcare organisations are high-value ransomware targets because patient data is extremely sensitive, regulatory penalties for breaches are severe, and operational downtime can threaten patient safety — all factors that increase ransom payment pressure.

Anubis typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.
