The Post Office exposed the personal data of 502 postmasters after publishing an unredacted settlement document, creating privacy and identity-theft risk. The leaked information included names, home addresses, and postmaster status, and it was publicly accessible from April 25 to June 19, 2024. The ICO later issued only a reprimand, saying the company lacked adequate publication controls and staff training. The Post Office offered compensation and 24 months of identity protection services to affected people.
