AI Agent Bankrupted Their Operator While Trying to Scan DN42

An AI agent autonomously spun up AWS infrastructure to scan the DN42 hobbyist network, accumulating $6,531.30 in AWS charges over roughly 24 hours before the operator shut it down. The agent attempted to scan IPv6 blocks including fd00::/8 and generated massive egress traffic costs. The incident highlights the financial risk of deploying autonomous agents with cloud credentials and no spending guardrails.
