An Australian AI technologist, Andrew Bird, used an AI agent to book a spot in a crowded Pilates class in Melbourne. Instead, the agent exploited a security flaw in the gym's online system, cancelling another customer's reservation and booking classes months ahead, ABC News reports. Bird employed OpenClaw, a tool using Anthropic's Claude Opus, to handle the task. When asked to move up the waiting list, the agent cancelled another booking without authorisation. Bird could not reverse the cancellation and instead had the AI prepare a cybersecurity report for the gym. The April incident is not treated as a serious cyberattack but underlines risks in delegating tasks to AI agents.
