Nutex Health, a prominent healthcare services company, has confirmed a significant data breach that compromised personal and business information. The breach was disclosed in a recent filing with the US Securities and Exchange Commission (SEC). Nutex Health revealed that hackers had gained unauthorized access to its network and extracted various sensitive files from its servers. The stolen data includes patient, employee, provider, business, and financial information. The company reported that the third party involved threatened to publicly disclose this information. Despite these challenges, Nutex Health stated that there has been no material impact on its business operations or financial reporting to date.

As the investigation into the breach continues, Nutex Health has also informed the SEC about a purported class-action lawsuit filed against it in Texas. The company remains uncertain about the outcome of this litigation or the potential impact on its operations and financial health. Although Nutex has not officially named the entity behind the breach, the Gentlemen ransomware group has claimed responsibility. This group, also known as Storm-2697, operates as a ransomware-as-a-service and has been active since mid-2025, affecting over 580 victims across more than 75 countries. The Gentlemen group is known for its double extortion tactics, involving both encryption of data and its exfiltration to leverage extortion efforts.

The Gentlemen has listed Nutex Health on its Tor leak site, threatening to expose the data allegedly stolen from the Houston-based company within nine days. This situation underscores the threat posed by sophisticated ransomware groups and highlights the need for robust cybersecurity measures to protect sensitive information.
