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 AnyDesk writing binary files to disk other than "gcapi.dll".
According to RedCanary research it is highly abnormal for AnyDesk to write executable files to disk besides gcapi.dll,
which is a legitimate DLL that is part of the Google Chrome web browser used to interact with the Google Cloud API. (See reference section for more details)
