Attack summary

Severity: high — Nutex Health is a publicly traded healthcare operator (NASDAQ: NUTX) with 27 active facilities and likely access to patient medical records, employee PII, and sensitive financial data. Confirmed data publication (status: data_published) of a healthcare entity's systems qualifies as high severity due to regulatory implications (HIPAA), patient safety, and operational criticality. Without explicit proof count or ransom demand statement, this remains 'high' rather than 'critical'.

The ransomware group claims to have compromised Nutex Health and published exfiltrated data. The leak post does not explicitly state whether data was encrypted, the specific categories of compromised data, or ransom demands.

What the group claims

nutexhealth.com zoominfo.com/c/nutex-health-inc/372032478 (NUTX, Nasdaq) — US healthcare company, based in Houston, Texas, founded in 2011 by Dr. Thomas Vo. It runs 27 small "micro-hospitals" in 12 states — small hospitals with full 24/7 emergency rooms. Model: fast, cheaper ER care between urgent care and giant hospitals; most revenue comes from Texas. Q2 2026: net income $65.8M (vs loss a year ago), EBITDA $90M, cash $205M, debt only $31M. Profit exploded because it wins 85%+ of insurance arbitrations (IDR) and got paid at higher out-of-network rates. Plans: 7 new hospitals by 2027 plus two share buyback programs. Main risk: the whole profit engine depends on the arbitration system — new regulation could cut it. Cheap-looking: P/E around 6, but volatile small-cap with thin analyst coverage.

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 813 public disclosures across our corpus. First observed on a leak site on September 9, 2025; most recent post September 2, 2026. The operation is currently active.

If your organisation is affected

A listing by thegentlemen means Nutex Health 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, CISA (United States), 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.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
