Compiled from this incident record and the threat intelligence profile for Anubis. Figures and technique mappings are quoted from the source data, not inferred.

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

Gellibrand Support Services was targeted by Anubis ransomware, one of the most active ransomware groups in our database with 112 confirmed victims globally. The attack was disclosed on September 9, 2026, when Gellibrand Support Services appeared on the group's dark web leak site.

Sector context: Organisations in this sector hold valuable data and operational systems that ransomware groups seek to exploit for financial gain through encryption and data exfiltration.

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. Last data update: Sep 18, 2026 12:00 UTC.
