Incident Analysis

Ejército Argentino was targeted by Qilin ransomware, one of the most active ransomware groups in our database with 2,072 confirmed victims globally. The attack was disclosed on July 24, 2026, when Ejército Argentino appeared on the group's dark web leak site.

Ejército Argentino is based in Argentina , operating in the Government & Defense sector. Argentina ranks #17 globally for ransomware attacks, with 152 victims in our database.

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.

Qilin 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.
