  • Engineer — Plan: Exposed LLM API keys in source code, CI/CD, or misconfigured environments are the primary entry point; audit repositories and secrets stores for exposed AI service credentials, scope IAM permissions for LLM service accounts to least-privilege, and enable cost anomaly alerts on AI APIs to catch abuse early.
  • SOC/IR — Plan: No IOCs are provided to sweep for immediately, but build or tune detections for anomalous LLM API call volumes, unexpected geographic origin of API requests, and sudden cloud cost spikes tied to AI services as proxy indicators of credential compromise.
  • Leader — Act: Cloud bills up to $1M from stolen LLM credentials represent a direct financial risk that could surface unexpectedly; confirm this quarter that engineering has LLM API key governance and cost alerting in place, and add LLM credential exposure to vendor risk reviews for AI SaaS dependencies.
