Gastroenterology & Hepatology Listed by LeakBazaar Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Gastroenterology & Hepatology has been listed by the LeakBazaar ransomware group after internal files were exfiltrated in a ransomware attack. The incident was disclosed on May 10, 2026, and an undisclosed number of people may have been affected; anyone connected to the organisation should check their status and take protective steps.
Inside the incident
Available information indicates that files were removed from Gastroenterology & Hepatology systems during a ransomware intrusion. The precise date of the intrusion, the initial access method, and the duration of unauthorized access are not disclosed in public reporting. The scale of any operational disruption to clinical services is also unreported.
The group claims the exfiltrated material includes a database covering 167,303 patients, along with associated records such as social security numbers, addresses, phone numbers, emails, diagnoses, medications, and pathology reports. These figures originate solely from the leak-site listing and have not been independently verified.
Who is LeakBazaar?
LeakBazaar is a ransomware group that maintains a public leak site to advertise data it asserts was obtained from victim organizations. Such groups commonly operate by encrypting files on compromised networks and then threatening to publish or sell copies of stolen material. Their listings typically include sample files or summary statistics to support the claim that data has been taken.
Public records of similar actors show repeated activity against organizations that hold large volumes of personal and medical information. Attribution of any specific incident rests on the group’s own statements until corroborated by law-enforcement or forensic findings.
Who is Gastroenterology & Hepatology?
Gastroenterology & Hepatology is a medical practice focused on disorders of the digestive system and liver. Organizations of this type routinely collect and store detailed patient histories, laboratory results, imaging reports, medication lists, and billing information. They also maintain administrative records that can include insurance details and contact information.
Because these practices handle sensitive diagnostic categories and long-term treatment data, any exposure of their systems carries implications for patient privacy that extend beyond immediate financial records.
What data was at risk
The only confirmed category of exposure is internal files removed during the ransomware attack. The leak-site listing claims the material contains records for 167,303 patients, including 124,761 social security numbers, addresses for 166,402 individuals, phone numbers for 164,296, and email addresses for 85,318. It further states the presence of 1,093,863 diagnosis entries, 1,547,142 medication records, and 186,246 pathology specimens with narrative reports.
The listing additionally claims that 49,798 patients have combinations of diagnoses and medications considered sensitive, with subsets related to mental health, substance use, sexually transmitted infections, cancer, and hepatitis C. The exact contents of any offered dataset remain unconfirmed outside the group’s statements.
The real-world impact
Individuals whose records appear in such listings face the possibility that personal identifiers and medical details could be used for identity fraud, targeted scams, or unwanted disclosure of health conditions. The presence of social security numbers alongside clinical information increases the potential for misuse over an extended period.
For the organization, the incident adds costs associated with investigation, notification, regulatory compliance, and possible remediation of systems. Healthcare entities also face ongoing requirements to protect patient information under applicable privacy regulations, irrespective of how the data left their control.
Were you affected?
Patients of Gastroenterology & Hepatology should monitor statements from the practice regarding any formal notification process. Individuals can also review their credit reports and financial accounts for unusual activity and consider placing fraud alerts with major credit bureaus if they have not already done so.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
