An AI called XBOW topped HackerOne's US leaderboard — beating every human bug hunter in the country. A year later, free open-source tools match it on its own benchmark, on hardware you already own.
We break down the rise of autonomous AI hackers: what XBOW actually did (and the asterisks the headlines skipped), the free tools chasing it — Shannon, Strix, and Tempest — the MCP trick that lets any AI drive 150+ real hacking tools, and what happens now that offensive security costs basically nothing. Defensive/educational: everything here runs against intentionally-vulnerable targets.
