Executive Summary
Pittsburgh Gastroenterology Associates experienced a network intrusion around August 12, 2025, confirmed on August 28, 2025, with the Sinobi ransomware group listing it on its leak site on August 20, 2025 (about 198 GB posted). The exposed files contained first and last names, dates of birth, treatment and procedure information, and health insurance information. Per the practice, Social Security numbers and financial information were NOT involved and its electronic medical record system was not accessed. The affected count was described as "thousands"; a DataBreach.com record cites ~47,525 (unconfirmed). (NOTE: prior record listed SSN as exposed; official notice states SSNs were not involved - corrected.)
ObscureIQ assessment: Severe risk of identity theft, medical fraud, and privacy harm. Specialty-care affiliation can also expose sensitive treatment context that supports targeted scams or embarrassment-based abuse.
Breach Impact
Because the exposed data centered on names, dates of birth, and treatment/procedure and insurance information, without Social Security numbers or financial data, the primary risks are medical identity fraud, insurance abuse, and GI-treatment-themed phishing rather than full identity theft. Gastroenterology procedures (colorectal, liver, bowel) carry privacy sensitivity that can support embarrassment-based or targeted scams.
