Autonomous Penetration Tester XBOW Tops HackerOne US Leaderboard

For the first time, an autonomous AI penetration tester, XBOW, has reached the top spot on the HackerOne US leaderboard. XBOW initially benchmarked itself against CTF challenges and open-source projects, uncovering and reporting numerous zero-day vulnerabilities. It then participated in HackerOne's bug bounty programs, conducting black-box testing on thousands of targets. XBOW's nearly 1060 validated vulnerability reports, including an unknown vulnerability in Palo Alto's GlobalProtect VPN, propelled it to the top ranking. This demonstrates the significant potential of AI in cybersecurity.
