Detects ChatGPT Enterprise Codex events that create an access token. Codex access tokens enable automated CLI or environment access and can be abused for persistence or lateral automation after account compromise. Treat tokens with a missing `expires_at` as higher priority during triage.

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

The rule states no platform. This is derived from the ATT&CK technique it maps to.

Known benign triggers

  • Developers create Codex tokens for CI runners and local environments.

Detections can measure how the public catalogue is used — which detections people look for, and which pages bring them here. It sets a cookie that recognises this browser for 180 days. It is never linked to an account and never follows you to other sites. Privacy notice
