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.

title: Potential Proxy Execution Via Explorer.EXE From Shell Process
id: 9eb271b9-24ae-4cd4-9465-19cfc1047f3e
status: test
description: |
Detects the creation of a child "explorer.exe" process from a shell like process such as "cmd.exe" or "powershell.exe".
Attackers can use "explorer.exe" for evading defense mechanisms by proxying the execution through the latter.
While this is often a legitimate action, this rule can be use to hunt for anomalies.
Muddy Waters threat actor was seeing using this technique.
