Social Security numbers and military job details were among the records accessed, according to US defense officials<\/p>\n
A Pentagon personnel system breach has reportedly exposed sensitive data on more than three million people, including military personnel and their families, several media outlets have reported, citing US defense officials. The disclosure follows a separate breach of the FBI\u2019s jobs website.
\nThe Defense Manpower Data Center (DMDC) system was reportedly accessed by a small number of unauthorized users between October 2025 and July 2026, affecting some 2.76 million living people and another 294,000 who are deceased, unidentified Pentagon officials have told CNN and ABC News.
\nAccording to them, the exposed files include Social Security numbers and other personal details, as well as information about military jobs and occupational specialties.
\nDMDC maintains more than 60 million records overall, including on active-duty and reserve troops, civilian employees, contractors, retirees, veterans, and military family members.
\nThe leak was initially reported by the Military Times last week citing an internal breach notice received by one of the affected individuals. The publication said two unnamed defense officials had confirmed the authenticity of the letter.<\/p>\n

According to the notice, DMDC said that a \u201csecurity vulnerability\u201d in a file-sharing system allowed unauthorized users to gain access to unencrypted personal information. The system was said to have been patched \u201cimmediately\u201d after it was discovered \u2013 nearly nine months after the unauthorized access began.
\nThe notice offered affected individuals a year of free credit monitoring services.<\/p>\n

However, the Pentagon has not yet officially confirmed the breach, nor commented on who was behind the intrusion or what they did with the information they accessed.
\nMeanwhile, the FBI is dealing with an unrelated breach claim involving its recruitment website. Last week, the hacking group ShinyHunters claimed it had stolen personal data on nearly all FBI agents, their spouses, and job applicants.
\nThe group said that the attack was \u201cnot financially motivated\u201d and instead of a ransom, demanded that the FBI remove a cybersecurity advisory published in May that ShinyHunters says contains false allegations about them.
\nThe FBI has said it is investigating and has notified employees, but has not yet established where the breach occurred or confirmed the scale of the theft.<\/p>\n","protected":false},"excerpt":{"rendered":"
