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: test
description: |
    Detects registry modifications related to the proxy configuration of the system, potentially associated with the Raspberry Robin malware, as seen in campaigns running in Q1 2024.
    Raspberry Robin may alter proxy settings to circumvent security measures, ensuring unhindered connection with Command and Control servers for maintaining control over compromised systems if there are any proxy settings that are blocking connections.
