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: LSASS Process Crashed - Application
id: a18e0862-127b-43ca-be12-1a542c75c7c5
status: experimental
description: |
Detects Windows error reporting events where the process that crashed is LSASS (Local Security Authority Subsystem Service).
This could be the cause of a provoked crash by techniques such as Lsass-Shtinkering to dump credentials.
