What it detects

This rule detects silent unattended installation of AnyDesk configured to start with Windows. The DeadLock ransomware operators deploy AnyDesk as a covert remote access tool for persistence and hands-on control. Silent installation with automatic startup indicates the tool is being planted rather than installed by a user.
