Disclosure context

About thegentlemen

thegentlemen is a ransomware group that emerged in September 2025, operating with apparent financial motivations based on their broad targeting of commercial sectors. The group has documented 267 victims across multiple countries, with primary focus on the United States, Thailand, France, Brazil, and India. Their targeting strategy demonstrates a preference for high-value sectors including manufacturing, technology, healthcare, and financial services organizations. Given the group's recent emergence and limited public documentation from established threat intelligence sources such as CISA, FBI, or major security research firms, specific details regarding their country of origin, operational structure, attack methodologies, encryption techniques, and whether they employ ransomware-as-a-service models remain unclear. The relatively high victim count of 267 in a short operational timeframe since September 2025 suggests either an aggressive campaign pace or potential inflation of victim numbers through affiliate operations, though without corroborating intelligence reports, the group's exact operational capabilities and notable campaigns cannot be definitively established. Current intelligence indicates the group remains active as of late 2025, though comprehensive threat profiling requires additional validated reporting from authoritative cybersecurity sources. The group has been linked to 424 public disclosures across our corpus. First observed on a leak site on September 9, 2025; most recent post May 18, 2026. The operation is currently active.

Attack summary

Severity: critical — Clark Fixture Technologies is ITAR-registered and supplies critical tooling to defense and space clients including Lockheed Martin Space Systems for Orion propulsion and life support assemblies. Data publication by the threat actor creates serious risk of exposure of export-controlled technical data, defense-sector client information, and potentially regulated PII, elevating this to critical severity.

The group 'thegentlemen' claims to have compromised Clark Fixture Technologies and has published data (disclosed status: data_published). No specific ransom amount or data size was stated, but the disclosure indicates exfiltration and publication of company data.
