The personal information of active military healthcare professionals has been exposed online by a Pentagon subcontractor.

Some of the individuals whose information was disclosed include those which hold top-secret security clearances, according to a report by ZDNet.

The U.S. government enlisted the help of Potomac Healthcare Solutions to provide healthcare professionals to its military organizations via Washington, DC-based contractor Booz Allen Hamilton. An insecure Potomac service is said to be the source of the data leak, according to MacKeeper Security Center lead researcher Chris Vickery, who discovered the data.

Many of the victims impacted by the breach work within the United States Special Operations Command. Vickery told ZDNet that the names, contract types, Social Security numbers, and duty start dates of the individuals impacted by the breach date back to 1998.
