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.

description: |
Detects network connections via finger.exe, which can be abused by threat actors to retrieve remote commands for execution on Windows devices.
In one ClickFix malware campaign, adversaries leveraged the finger protocol to fetch commands from a remote server.
Since the finger utility is not commonly used in modern Windows environments, its presence already raises suspicion.
Investigating such network connections can also help identify potential malicious infrastructure used by threat actors
