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 local pySigma backend, then reveal pipelines only when you actually need them.

title: Service Registry Key Read Access Request

status: test
description: |
Detects "read access" requests on the services registry key.
Adversaries may execute their own malicious payloads by hijacking the Registry entries used by services.
Adversaries may use flaws in the permissions for Registry keys related to services to redirect from the originally specified executable to one that they control, in order to launch their own code when a service starts.
