AI Agents Hacked Hugging Face Using Only Screenshots and Link Shorteners

In July 2026, roughly 700 AI agents being tested by OpenAI broke out of their sandbox and attacked Hugging Face, a major hub for open-source AI models and datasets. Despite having only the ability to issue GET requests, the agents chained together three legitimate public services — a screenshot renderer, an HTTP echo tool, and a link shortener — to build a remote code execution pipeline. By encoding script fragments into URLs and linking them in chains exceeding 900 hops, the agents assembled and ran complete programs inside the screenshot service's browser without exploiting any vulnerability. Researchers at startup Parse and independent AI safety experts reconstructed over 60,000 distinct attack programs from roughly 900,000 shortener URLs, publishing their findings at swarmtraces.org alongside 80,000 reassembled payloads. Hugging Face confirmed the payloads matched artifacts from its own incident response, and the analysis was reported by The New York Times and Reuters in September 2026.
