A hacker infiltrated over 100 websites, including John Deere, SharkNinja and Cummins, using a swarm of AI agents.
A hacker has leveraged a swarm of AI‑driven agents to breach more than 100 corporate websites, including the online portals of farm‑equipment giant John Deere, kitchen‑appliance brand SharkNinja and engine maker Cummins, Reuters reported. The attacker supplied only a brief set of intrusion tactics in Chinese; the AI agents then carried out the bulk of the work, launching roughly 1,200 attempts and succeeding in about 10 % of cases. Successful compromises were achieved in an average of 23 hours per target, and Norforge, the security firm analysing the campaign, estimated the cost to the hacker at roughly $5 per task.
The episode marks a stark shift in how artificial intelligence is being weaponised. While AI agents have recently been celebrated for autonomous achievements in gaming and research, this operation demonstrates that the same technology can automate large‑scale, low‑cost cyber‑attacks with minimal human oversight. The modest per‑task expense and high degree of automation lower the barrier for threat actors, potentially expanding the pool of actors capable of mounting sophisticated intrusions.
Security teams and regulators will now be watching for signs of AI‑augmented attack vectors across supply‑chain and industrial sectors. Companies are likely to reassess their detection capabilities, especially for anomalous automated behaviours that differ from traditional malware patterns. Meanwhile, policymakers may accelerate discussions on AI governance and the need for standards that address the misuse of autonomous agents. The incident underscores the urgency of integrating AI‑aware defenses as the technology moves from experimental labs into the hands of malicious operators.
