Hackers Steal Data of 3M Pentagon Personnel
In the US, following the hack of a job placement site for the FBI, the Pentagon's employee database was compromised. Hackers may have gained access to personal data of more than 3 million military personnel, veterans, Pentagon employees, contractors, and family members of military members.
Consensus

- The breach affected over 3 million individuals, including 2.76 million living people and 294,000 deceased individuals.
- The unauthorized access occurred from October 2025 to July 16, 2026.
- The data included Social Security numbers, job positions, names, dates of birth, contact information, and other personal details.
- The DMDC system was found to have an unpatched vulnerability that was only resolved on July 16, 2026.
- The Pentagon confirmed that the vulnerability was addressed after discovery.
- There is no evidence that the stolen data has been used for malicious purposes.
- The DMDC stores over 60 million records of military personnel, veterans, contractors, and family members.
