United Kingdom’s MoD announces the results of its bug bounty program with HackerOne The United Kingdom’s Ministry of Defence (MoD) announced the conclusion of its first bug bounty challenge with HackerOne. The Ministry of Defence program was a 30-day, hacker-powered security test aimed at surfacing vulnerabilities before they can be exploited by adversaries. Following the recent U.K. Integrated Review, the U.K. government has called for “a more robust position on security and resilience” and “an emphasis on openness as a source of prosperity.” The MoD Challenge is part of an organization-wide commitment to build back a culture of transparency and collaboration around security to combat cyber threats and improve national security.
