Pentagon Personnel Records Breach Exposes Data of Millions
The U.S. government is notifying millions of current and former military personnel that their personal data was stolen in a months-long breach affecting the Defense Manpower Data Center (DMDC). The breach, which occurred between October 2025 and July 2026, exposed sensitive information such as Social Security numbers, names, dates of birth, race, sex, and details about military service. Approximately 2.8 million living individuals and nearly 300,000 deceased people were affected. The DMDC maintains over 60 million records for U.S. military personnel, civilian staff, and their families to manage benefits like healthcare and retirement. It also plays a critical role in identity management by linking service members and contractors to access credentials such as smart cards and passwords used across Pentagon systems. While the Department of Defense stated there is no indication that data was misused, it did not explain how this conclusion was reached. This breach follows similar incidents involving federal workers' personal information, including a recent one at the FBI attributed to ShinyHunters hackers. These breaches raise concerns about counterintelligence risks and potential foreign exploitation of sensitive government employee records.
