Data on more than 3 million individuals leaked from Pentagon database
ABC News reported this on September 29, citing a US Department of Defense official. Prior to this, the cyberattack was reported by the Military Times publication.
According to the Pentagon spokesperson, between October 2025 and July 2026, a small number of unauthorized users gained unauthorized access to personal data stored at the Defense Manpower Data Center (DMDC).
"As soon as this situation was identified, DMDC immediately mitigated the vulnerability," the department spokesperson said.
According to the assessment of the ABC News interlocutor, the volume of the leak and the level of confidentiality of the exposed information could raise national security concerns. In particular, the files contained information about the positions of military personnel and civilian employees.
DMDC is one of the Pentagon's primary personnel databases. It stores records on active-duty military personnel, reservists, civilian employees, contractors, retirees, veterans, and military family members.
According to the Pentagon, there are currently no indications that the obtained data has been used for malicious purposes.
Earlier, on September 23, the US Federal Bureau of Investigation also reported a potential cyberattack on its job posting website. It is currently unknown how many people were affected by that incident.
