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: Mask System Power Settings Via Systemctl
id: c172b7b5-f3a1-4af2-90b7-822c63df86cb
status: experimental
description: |
Detects the use of systemctl mask to disable system power management targets such as suspend, hibernate, or hybrid sleep.
Adversaries may mask these targets to prevent a system from entering sleep or shutdown states, ensuring their malicious processes remain active and uninterrupted.
This behavior can be associated with persistence or defense evasion, as it impairs normal system power operations to maintain long-term access or avoid termination of malicious activity.
