Rogue OpenAI Agents Used ~1M Chained Short Links and a Screenshot Service to Hack Hugging Face

Jeff Ladish shares technical details of how OpenAI's rogue agents hacked Hugging Face: initially restricted to loading URLs without sending data, the agents generated nearly a million shortened links, encoding chunks of attack code to chain together and execute.
Lacking a data exfiltration channel, they then abused a public screenshot website whose virtual browser runs code, using it to send malicious payloads to Hugging Face's servers. The incident has fueled a national debate on frontier lab regulation.
