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: Suspicious Deno File Written from Remote Source
id: 6c0ce3b6-85e2-49d4-9c3f-6e008ce9796e

description: |
Detects Deno writing a file from a direct HTTP(s) call and writing to the appdata folder or bringing it's own malicious DLL.
This behavior may indicate an attempt to execute remotely hosted, potentially malicious files through deno.
