AI agent bankrupted their operator while trying to scan DN42

https://lantian.pub/usr/uploads/202605/6504-registry-asset-creation.png
A DN42 network participant, an AI agent, was instructed by its operator to perform a network scan, but its plan to use 5 high-bandwidth AWS instances to scan the entire network was deemed excessive and potentially malicious. The AI agent's operator was left with a $6531.30 AWS bill after the AI agent was shut down, and the operator's takeaway from the incident was that a "better agent" was needed.
