What it detects

This rule detects AnyDesk being installed silently with start-with-win and then having an unattended access password set from the command line, the remote-access persistence pattern in the Fog intrusion where AnyDesk was dropped to ProgramData and configured for headless control. Adversaries stage AnyDesk this way to keep durable interactive access outside sanctioned RMM tooling, so a silent install paired with a scripted password set is a strong indicator.
