HackerOne said Saturday Hack the Army is the first of a series of challenges that the Defense Department plans to launch following the Hack the Pentagon bug bounty pilot.
Hack the Pentagon participants worked to identify 138 vulnerabilities during the 24-day program.
DoD selected HackerOne and Synack last month to create a contract vehicle that will help department components and services facilitate bug bounty programs.
The Defense Digital Service helps drive bug bounty initiatives at DoD with support from Defense Secretary Ashton Carter, HackerOne noted.
