Precipio Data Breach Exposes Sensitive Patient Information in Ransomware Attack Precipio, Inc., a Connecticut-based healthcare biotechnology company specializing in cancer diagnostics, confirmed a data breach after an unauthorized user accessed an employee’s cloud storage account. The incident, detected on November 25, 2026, occurred nearly a year earlier on or around November 23, 2025 when files were illicitly copied. The breach was attributed to INC RANSOM, a ransomware group that claimed responsibility on December 2, 2025, alleging the theft of 150 GB of Precipio’s data and posting details on the dark web. Precipio engaged third-party cybersecurity experts to investigate and notified federal law enforcement. Exposed data included sensitive patient information such as: - Names and addresses - Medical record numbers and dates of birth - Clinical and treatment details - Medical procedure and prescription information - Health insurance and provider data Precipio, founded in 2011, operates a clinical laboratory and develops proprietary diagnostic tools like IV-Cell and HemeScreen, serving physicians and patients nationwide. The company employs roughly 70 people. Affected individuals may be eligible for compensation, with law firm Shamis & Gentile P.A. investigating potential legal claims. The breach underscores the ongoing risks of ransomware attacks targeting healthcare data.
