Two Marines sue the Pentagon over a data breach affecting more than 3 million people

A flaw in a Defense Manpower Data Center file-sharing system let unauthorized users reach names, birth dates, Social Security numbers and military jobs for about nine months.

The lawsuit says inspector general reports have warned of cybersecurity problems since 2021 and that the department ignored them.

The Marines say the department showed “flagrant disregard for the privacy interests of service members and other military-adjacent individuals”.
