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.

title: OpenEDR Spawning Command Shell
id: 7f3a9c2d-4e8b-4a7f-9d3e-5c6f8a9b2e1d
status: experimental
description: |
    Detects the OpenEDR ssh-shellhost.exe spawning a command shell (cmd.exe) or PowerShell with PTY (pseudo-terminal) capabilities.
    This may indicate remote command execution through OpenEDR's remote management features, which could be legitimate administrative activity or potential abuse of the remote access tool.
    Threat actors may leverage OpenEDR's remote shell capabilities to execute commands on compromised systems, facilitating lateral movement or other command-and-control operations.
