ThreatAI Analysis

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

About the Linkc group

Linkc is a ransomware group first observed in February 2025, operating a Tor-based data leak site and targeting US-based AI, cloud, aerospace, and manufacturing companies — including H2O.ai — demanding ransoms as high as $15 million using double-extortion tactics. Linkc has listed 4 victims since January 2025.

Incident Analysis

h2o.ai was targeted by Linkc ransomware, one of the most active ransomware groups in our database with 4 confirmed victims globally. The attack was disclosed on February 19, 2025, when h2o.ai appeared on the group's dark web leak site.

h2o.ai is based in United States , operating in the Technology sector. United States ranks #1 globally for ransomware attacks, with 9,476 victims in our database.

Sector context: Technology companies hold intellectual property, customer data, and source code — all highly valuable assets. A successful ransomware attack can also put downstream customers at risk through supply chain exposure.

Linkc 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.
