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.

    Detects DNS queries to domains commonly used by threat actors to host malware payloads or redirect through URL shorteners.
    These include platforms like Cloudflare Workers, TryCloudflare, InfinityFree, and URL shorteners such as tinyurl and lihi.cc.
    Such DNS activity can indicate potential delivery or command-and-control communication attempts.
