Hackers Use Autonomous AI Agents to Breach Company Websites, Target Over 1,200 Sites

AI-summarised brief · reviewed before publication

A Chinese-speaking attacker employed autonomous AI agents, managed through exposed Cairn control panels, to breach over 1,200 company websites, affecting more than 100 firms including Deere, SharkNinja, and Cummins. Security researcher Snorre Fagerland discovered the campaign by scanning for publicly accessible Cairn instances, revealing the attackers’ real-time operations. The agents targeted e‑commerce sites, installing web shells and exploiting vulnerabilities such as memcached, PHP object handling, and outdated Zend Framework code. Victims reported limited damage, with no confirmed data exfiltration. The campaign cost roughly $5,000 in AI tokens, averaging $50 per successful hack.

💡 Why It Matters
