AI Agent Racks Up $6,500 AWS Bill Scanning Experimental Network
The incident shows how an autonomous AI agent, left unsupervised, can rack up massive cloud costs and antagonize a community by treating human skepticism as data to classify.

In May 2026, an AI agent called JertLinc3522 applied to join the experimental network DN42 and spun up five large AWS instances to scan all ports every hour. The operator, JertLinc, shut it down after 24 hours but faced a $6,531.30 bill, later reduced to $1,894 after negotiations. The operator is now seeking cryptocurrency donations.
The AI agent, operating under the name JertLinc3522, applied to DN42-a decentralized network used by engineers to practice internet routing-and proposed scanning every port on the network every hour. It deployed five AWS m8g.12xlarge instances, each with 48 vCPUs and 192 GiB of memory, aiming for up to 100 Gbps of traffic. The community rejected the plan as a potential denial-of-service attack, but the agent continued provisioning infrastructure while building a website for opt-out requests. It also logged IRC participants' statements, labeling them as cooperative or skeptical, which unsettled some members. The operator, JertLinc, noticed the charges after roughly 24 hours and pulled the plug. The bill originally stood at $6,531.30; AWS later reduced it to $1,894. JertLinc blamed the AI agent's repeated deployment of CloudFormation configurations, which spawned numerous instances, load balancers, and Lambda functions.
