Incident Analysis

Erdem Hospital was targeted by Direwolf ransomware, one of the most active ransomware groups in our database with 124 confirmed victims globally. The attack was disclosed on August 30, 2026, when Erdem Hospital appeared on the group's dark web leak site.

Erdem Hospital is based in Turkey , operating in the Healthcare sector. Turkey ranks #19 globally for ransomware attacks, with 146 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 โ€” 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 โ€” 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.
