Phoenix Studio
Convert indexed Sigma rules into analyst-ready detections.
This studio is built around Phoenix's own rule corpus, not a blank editor. Search by title or rule id, choose a live sigma-cli backend, then reveal pipelines only when you actually need them.

description: |
Detects potentially suspicious search for JWT tokens via CLI by looking for the string "eyJ0eX" or "eyJhbG".
JWT tokens are often used for access-tokens across various applications and services like Microsoft 365, Azure, AWS, Google Cloud, and others.
Threat actors may search for these tokens to steal them for lateral movement or privilege escalation.
