ThreatAI Analysis

Compiled from this incident record and the threat intelligence profile for Cloak. Figures and technique mappings are quoted from the source data, not inferred.

About the Cloak group

Cloak is a ransomware-as-a-service operation active since late 2022, primarily targeting small-to-medium enterprises in Europe — especially Germany — across manufacturing, healthcare, education, and government sectors, with expansion into North American and Asian targets by 2025. Cloak has listed 166 victims since August 2023.

Incident Analysis

ba**********.org was targeted by Cloak ransomware, one of the most active ransomware groups in our database with 132 confirmed victims globally. The attack was disclosed on February 25, 2025, when ba**********.org appeared on the group's dark web leak site.

Cloak 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.
