HackerOne has released the results of the U.S. Air Force‘s second bug bounty challenge that invited hackers from 26 countries to identify vulnerabilities in the military branch’s systems.
The company said Thursday 27 hackers participated in the 20-day Hack the Air Force 2.0 event and found 106 valid vulnerabilities, which earned the participants $103,883 in total bounties.
HackerOne worked with the Defense Digital Service to host Hack the Air Force 2.0 in December in New York.
At the event, the Air Force issued the highest single bounty of any federal program to-date worth $12,500.
The challenge drew participants from U.S., Canada, U.K., Sweden, Netherlands, Belgium and Latvia.
Defense Department and Air Force personnel collaborated with hackers to find vulnerabilities and address them in real-time.
Hack the Air Force is part of DoD’s Hack the Pentagon cybersecurity initiative, which has helped remediate 3,000 vulnerabilities across government systems since its launch in 2016.
The Air Force’s first bug bounty challenge ran from May 30 to June 23, 2017 and led to 207 valid reports as well as $130,000 in rewards.
