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 live sigma-cli backend, then reveal pipelines only when you actually need them.

description: |
Detects attempts to modify the registry using VBScript's CreateObject("Wscript.shell") and RegWrite methods via common LOLBINs.
It could be an attempt to modify the registry for persistence without using straightforward methods like regedit.exe, reg.exe, or PowerShell.
Threat Actors may use this technique to evade detection by security solutions that monitor for direct registry modifications through traditional tools.
