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.

status: experimental
description: |
Detects WinRAR creating files in Windows startup locations, which may indicate an attempt to establish persistence by adding malicious files to the Startup folder.
This kind of behaviour has been associated with exploitation of WinRAR path traversal vulnerability CVE-2025-6218 or CVE-2025-8088.
