A data breach at the Pentagon’s vast HR system has exposed Social Security numbers and other personal information of current and former military personnel, raising counterintelligence concerns among national security experts.
“Unauthorized users” gained access to a vulnerable computer server belonging to the Defense Manpower Data Center (DMDC) beginning last October, but it wasn’t until nine months later, in July, that the Pentagon discovered and remediated the issue, according to a letter the center sent to victims of the breach reviewed by CNN.
The DMDC maintained at least 60 million records as of fiscal 2024, according to its website. It’s unclear how many have been impacted, but Military Times reported that four million Department of Defense personnel could be affected by the breach.
