## Summary

A cybersecurity researcher reported that a Chinese‑speaking hacker leveraged AI agents to scan and compromise more than 1,200 websites, leading to breaches of over 100 entities. Among the victims were Deere and SharkNinja. The researcher said the entire operation cost roughly ~$5,000.

The hacker reportedly used publicly available AI tools to automate tasks such as reconnaissance, credential stuffing and exploitation, allowing a large‑scale attack at very low cost. The researcher observed the activity over the past few weeks but did not disclose the hacker’s identity. Neither Deere nor SharkNinja commented on the incident.

The case underscores growing concerns that inexpensive AI‑driven agents can empower threat actors to launch widespread cyber‑attacks, prompting companies to reassess defenses against automated, AI‑assisted intrusion techniques.

## Key points

- Hacker used AI agents to target over 1,200 websites and breach more than 100 entities, including Deere and SharkNinja.
- Operation cost roughly ~$5,000 in total, according to the researcher.
- Incident highlights low‑cost AI‑driven attacks on large firms, raising security concerns.

## Why it matters

Shows how cheap AI tools can enable large‑scale cyber‑attacks, forcing organizations to strengthen defenses against automated AI‑assisted threats.
