New Hampshire Retirement System (NHRS) notified the NH Attorney General of a data security breach affecting 1 individual. In late September 2021, an error in the MyAccount portal caused a cached document containing PII (names, address, SSN, DOB) of one retiree to be erroneously presented to two other members. NHRS deactivated the portal, engaged the vendor to fix the caching bug, implemented firewall protections, and notified the affected individual.
