About the Direwolf group

Dire Wolf is a sophisticated human-operated ransomware group first documented in May 2025, written in Golang using Curve25519/ChaCha20 encryption, targeting manufacturing and technology sectors across 13+ countries with ransoms up to $500,000, operated by a tight core team rather than a broad affiliate program. Direwolf has listed 131 victims since April 2025.

Incident Analysis

Anadolu Hastaneleri was targeted by Direwolf ransomware, one of the most active ransomware groups in our database with 135 confirmed victims globally. The attack was disclosed on July 20, 2025, when Anadolu Hastaneleri appeared on the group's dark web leak site.

Anadolu Hastaneleri is based in Turkey , operating in the Healthcare sector. Turkey ranks #19 globally for ransomware attacks, with 149 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.

Direwolf 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.
