*The U.S. Department of Defense’s Defense Manpower Data Center (DMDC) experienced a months-long breach of an unspecified file-sharing system that exposed unencrypted personnel records—including Social Security numbers, names, dates of birth, and service information—affecting about 2.8 million living people and roughly 300,000 deceased individuals between October 2025 and mid‑July 2026; the attacker(s) remain unknown and the DoD reports no confirmed misuse of the data.*
