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 local pySigma backend, then reveal pipelines only when you actually need them.

description: |
Detects the execution of TruffleHog, a popular open-source tool used for scanning repositories for secrets and sensitive information, within an AWS environment.
It has been reported to be used by threat actors for credential harvesting. All detections should be investigated to determine if the usage is authorized by security teams or potentially malicious.
