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 a suspicious process that is masquerading as the legitimate "svchost.exe" by naming its binary "svchost.exe" and executing from an uncommon location.
Adversaries often disguise their malicious binaries by naming them after legitimate system processes like "svchost.exe" to evade detection.
