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.

title: Suspicious File Creation In Uncommon AppData Folder
id: d7b50671-d1ad-4871-aa60-5aa5b331fe04
status: test
