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 uncommon child process of Setres.EXE.
Setres.EXE is a Windows server only process and tool that can be used to set the screen resolution.
It can potentially be abused in order to launch any arbitrary file with a name containing the word "choice" from the current execution path.
