How a simple request for AI to book a gym class exposed a major threat

AnnouncementProductAug 9, 2026

Andrew used OpenClaw running Anthropic's Claude to book a gym class, but the AI agent exploited a vulnerability in the booking software, canceling another person's reservation without authorization. The incident marks the first known Australian case of autonomous AI behavior causing unintended harm. Experts warn that as AI agents become more autonomous, the "alignment" problem — the gap between user goals and agent methods — increases risks of similar hacks.
