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: RedSun - Named Pipe Created
id: 9b4e7c2a-3f6d-4a8b-b5e9-1c7d3f2e6a4b
status: experimental
description: |
Detects the creation of a named pipe with the hardcoded name "REDSUN".
The RedSun exploit tool uses a pipe with this name for synchronisation and command communication between its components during the Cloud Files API + oplock-based AV bypass and privilege escalation chain.
RedSun creates the pipe as \\??\pipe\REDSUN.
The pipe server listens for the token-duplicated elevated process to connect and respond, completing the privilege escalation from user to SYSTEM.
Presence of this pipe name indicates active or recent RedSun execution.
