Incident Analysis

Reni Farmácias Associadas was targeted by Doommageddon ransomware, one of the most active ransomware groups in our database with 11 confirmed victims globally. The attack was disclosed on July 19, 2026, when Reni Farmácias Associadas appeared on the group's dark web leak site.

Reni Farmácias Associadas is based in Brazil , operating in the Healthcare sector. Brazil ranks #7 globally for ransomware attacks, with 446 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.

Doommageddon 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.
