Incident Analysis

Anjos Ramos was targeted by Gunra ransomware, one of the most active ransomware groups in our database with 54 confirmed victims globally. The attack was disclosed on May 24, 2025, when Anjos Ramos appeared on the group's dark web leak site.

Anjos Ramos is based in Brazil , operating in the Business Services sector. Brazil ranks #7 globally for ransomware attacks, with 462 victims in our database.

Sector context: Business services firms often have access to multiple client environments, making them high-value pivot points for ransomware operators seeking to maximise impact across multiple victim organisations.

Gunra 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.
