On April 23, 2025, Orthopaedic Specialists of Connecticut (OSC) disclosed a significant data breach that affected 22,541 individuals in the United States, according to the U.S. Department of Health and Human Services.

The breach was the result of a ransomware attack carried out by the group known as INC RANSOM. The attackers gained unauthorized access to OSC’s network environment on March 2, 2025, and may have acquired sensitive data during this incident.

OSC discovered the breach after detecting unusual activity and immediately engaged a specialized third-party forensic incident response firm to secure their systems and investigate the extent of the unauthorized activity. The forensic investigation confirmed that certain data had likely been acquired by the attackers.

The compromised information includes a combination of personally identifiable information (PII) and protected health information (PHI) including first name, last name, date of birth, Social Security number, health insurance ID number, and medical information.

The breach was also posted on a dark web network, with INC RANSOM claiming responsibility and asserting they had obtained the organization’s data.
