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 a network connection initiated by the Add-In deployment cache updating utility "AddInutil.exe".
This could indicate a potential command and control communication as this tool doesn't usually initiate network activity.
