   Pentagon Breach Exposes Data of Nearly 3 Million Personnel

   Hackers breached the Department of Defense's Defense Manpower Data Center (DMDC) human resources system, exposing sensitive data on nearly 3 million living and deceased people. The stolen information includes Social Security numbers and military job details for current and former military and civilian personnel. Unauthorized access occurred between October 2025 and July 2026. The Pentagon has patched the vulnerability and stated there is currently no evidence that the exposed information has been misused. National security experts warn the breach creates counterintelligence concerns for those in sensitive roles.

   Why it matters

   The DMDC manages vast personnel records for the U.S. military. Exposure of job-related records and government IDs can make personnel targets for foreign intelligence services. The delay between the initial breach and discovery complicates the assessment of data misuse.

   What is confirmed

   • A breach of the Defense Manpower Data Center exposed sensitive data on nearly 3 million people.
   • The stolen records include Social Security numbers and details about jobs held by military and civilian personnel.
   • Unauthorized users accessed the system between October 2025 and July 2026.
   • The Pentagon has secured the source of the leak and patched the vulnerability.
   • The affected group includes current and former military personnel as well as deceased individuals.

   Still unconfirmed

   • The breach exposed unencrypted personal data.
   • The breach was targeting the Department of War.

   What to watch next

   • Evidence of the stolen data being sold or used by foreign intelligence services.
   • Official notification timelines for the millions of affected service members.
   • Congressional hearings regarding the months-long delay in discovering the breach.
