Breach of Pentagon personnel database exposed data of 2.76 million living service members and civilian employees
Unauthorized parties had access from October 2025 to July 2026 to the Defense Manpower Data Center system, the Pentagon's main personnel database, and through it to data on 2.76 million living and 294,000 deceased people, ABC News reports, citing a Defense Department official. The exposed information includes Social Security numbers and descriptions of positions held by service members and civilian employees. The Pentagon says it patched the flaw immediately after discovering it and that there is no evidence the data has been misused.
