What the group claims

fachhandel-hell.at Hell Helmut GmbH is a small family-owned B2B wholesale company based in Hall in Tirol, Austria, operating for over 20 years and specialized in sanitary and heating supplies. The company positions itself as a system supplier for underfloor heating, serving professional installers across Tyrol, Vorarlberg, and Salzburg. It sources directly from leading manufacturers — primarily IMI Heimeier (thermostatic and balancing valves) and Uponor (underfloor heating and drinking water systems) — guaranteeing original quality. Its key differentiator is in-house prefabrication: ready-made manifold stations and water metering stations built exclusively from IMI and Uponor components. The business is 100% owned and personally managed by its founder Helmut Hell, with a lean team of about 5–6 people. Overall, it is a classic regional specialist wholesaler: small, owner-run, and focused on system-based project supply rather than retail.

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 889 public disclosures across our corpus. First observed on a leak site on September 9, 2025; most recent post September 26, 2026. The operation is currently active.

If your organisation is affected

A listing by thegentlemen means Hell Helmut GmbH appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, CERT.at (Austria), as required for your jurisdiction.
Monitor for the data appearing on thegentlemen's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
