Veradigm Investigates Alleged Data Breach After Hacker Group Claims Theft of 3.5 Million Patient Records
On September 5, 2026, the hacker group The Gentlemen claimed responsibility for a suspected cyberattack on Veradigm, a publicly traded healthcare data solutions and practice management company (formerly Allscripts). According to a post on the dark web monitoring site Ransomware.live, the group alleged it exfiltrated over 3.5 million personal patient records, including names, contact details, Social Security numbers, and other sensitive data. The attack is believed to have occurred the day before the claim was made.
Veradigm has not yet confirmed the breach, and details about its scope or impact remain unclear. However, legal teams associated with ClassAction.org are investigating the incident, seeking potential plaintiffs for a class action lawsuit. Affected individuals including healthcare providers and patients linked to Veradigm’s services may be eligible for compensation related to privacy violations, financial losses, or other damages.
This incident follows a history of prior breaches involving Veradigm and its affiliated entities, though no additional technical or forensic details have been disclosed at this time. The investigation is ongoing.
