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: Remote Thread Creation In Mstsc.Exe From Suspicious Location
id: c0aac16a-b1e7-4330-bab0-3c27bb4987c7
status: test
description: |
Detects remote thread creation in the "mstsc.exe" process by a process located in a potentially suspicious location.
This technique is often used by attackers in order to hook some APIs used by DLLs loaded by "mstsc.exe" during RDP authentications in order to steal credentials.
