ThreatAI Analysis

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

About the Warlock group

The Warlock ransomware and operator(s) are believed to be attributed to Storm-2603, a China-based threat actor who is also known to have deployed LockBit ransomware. There's also a crossover between victims with Black Basta. Both are RaaS and have a long list of known and unknown affiliates. Having said that, this is possibly an affiliate (likely a cybergroup) of both of those groups. The Alliance & Association would technically be Encryptor Sharing, but this is realistically more of an "Old Affiliate" that created their own ransomware encryptor and operation. Warlock has listed 78 victims since April 2025.

Incident Analysis

clearybuilding.us was targeted by Warlock ransomware, one of the most active ransomware groups in our database with 78 confirmed victims globally. The attack was disclosed on August 17, 2025, when clearybuilding.us appeared on the group's dark web leak site.

clearybuilding.us is based in United States , operating in the Construction sector. United States ranks #1 globally for ransomware attacks, with 9,425 victims in our database.

Sector context: Construction firms often hold sensitive project data, client financials, and intellectual property. The industry's typically lean IT security teams can make them more vulnerable.

Warlock 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.
