Henry Rossi & Co. 2026 Data Breach

Henry Rossi detected anomalous activity in its systems on January 18, 2026, and began an investigation with outside forensic specialists. The investigation found unauthorized access to the firm's environment on January 17 and 18 and determined that certain files were accessed. The firm completed its review of sensitive information in those files on April 3.

Audit files for the Steamfitters Local #449 Medical & Benefit Fund contained certain individuals' full names, Social Security numbers, and dates of birth. The notice does not say that every field was present for every person, nor does it state that the files were downloaded or publicly released.

Henry Rossi conducted a forensic investigation, reviewed its existing policies and procedures, and said it implemented additional administrative and technical safeguards. It provided notice through its website and the media and said it was notifying required regulators.

Notice recipients should monitor credit reports, account statements, and health-insurance explanations of benefits for activity they do not recognize. People whose Social Security numbers were involved may consider a free fraud alert or credit freeze and report suspicious activity to the relevant organization.
