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.

Detects the setting of the REGISTERAPPRESTART compatibility layer on an application.
This compatibility layer allows an application to register for restart using the "RegisterApplicationRestart" API.
This can be potentially abused as a persistence mechanism.
