Mass Vulnerability Scans Spoofing AI Bots Like ClaudeBot

A new report from KnownAgents reveals that attackers are spoofing AI bot user agents, such as ClaudeBot, to conduct mass vulnerability scans across the web. The data shows that AI scraping traffic is dominated by ClaudeBot, meta-externalagent, and Amazonbot, while AI fetching is led by ChatGPT-User. The report also highlights that 98.5% of bots comply with robots.txt, but spoofing undermines these rules.
