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 the execution of the MSXSL utility. This can be used to execute Extensible Stylesheet Language (XSL) files. These files are commonly used to describe the processing and rendering of data within XML files.
Adversaries can abuse this functionality to execute arbitrary files while potentially bypassing application whitelisting defenses.
