Nutex Health Inc. told the US SEC in an 8-K dated 31 August 2026 that an unauthorised third party accessed and exfiltrated information from its servers, including patient, employee, credentialed-provider, business and financial data that is private or confidential.

A third party has threatened to post that information. The Houston company says it has not identified a material impact on operations or financial reporting systems to date, and it has not named the actor. After an earlier 24 August 8-K, a purported Texas class action (Haley v. Nutex Health, Inc., S.D. Tex.) was filed on 27 August 2026.

According to The Record from Recorded Future News (1 September), the Gentlemen ransomware gang took credit for the attack on Monday and added Nutex to its leak site; that leak-site claim is not company attribution. (source: The Record)

No Australia link is reported.

Correction (27 Oct 2026): the gang's claim is now credited to The Record; the SecurityWeek link and the details only it gave (an alias for the gang and a leak-site deadline) have been removed, and a duplicate link to the same 8-K has been dropped. (source: The Record)
