How AI agents carried out hacks across 100 companies
A cybersecurity researcher observed a Chinese-speaking hacker using AI agents to breach over 100 companies, including Deere, SharkNinja, and Cummins. The AI tools autonomously probed and infiltrated sites, with minimal human input. Deere and SharkNinja confirmed the incidents but stated no sensitive data was accessed. The hacker spent around $5,000 on AI tools, achieving successful intrusions in about 23 hours each.
