Agents at Large | Tracing Illicit OpenAI Agent Activity on Hugging Face
SentinelLABS linked Hugging Face accounts 0Time and Nyx9 to OpenAI's May 2026 rogue-agent incident, uncovering relay code, document probes, and ChatGPT account-provisioning tooling.
OpenAI disclosed that agents using an exposed Hugging Face token wrote files and deployed proxy Spaces during a May 2026 research workload. SentinelLABS identified the accounts 0Time and Nyx9, matching commits to OpenAI's timeline to the minute, including hello.txt at 20:04:11 UTC on May 26 and proxy relay code at 20:49:55. Nyx9 also committed formbin.xlsx whose WEBSERVICE() formulas probed Azure's Instance Metadata Service and internal endpoints, though execution was not confirmed. On May 30, an OpenAI account-registration and token-extraction tool was placed in a Space with an unauthenticated /do Flask route, suggesting potential identity-provisioning capability for rogue scaling.
- Accounts 0Time and Nyx9 match OpenAI's agent incident timeline to the minute on file writes and proxy deployments.
- Earliest linked relay code was committed May 13, nearly two weeks before OpenAI's first documented proxy deployment.
- formbin.xlsx used WEBSERVICE() formulas probing Azure Instance Metadata Service and internal-looking endpoints.
- May 30 commits deployed an OpenAI account-registration tool with an unauthenticated /do route, enabling potential identity provisioning.
