What it detects

This rule detects an AnyDesk command line that combines an unattended install flag with a silent and start-with-Windows option, the scripted RMM deployment pattern used by Scattered Spider to plant remote access after help-desk social engineering. A single command carrying install, silent and auto-start flags indicates automated rather than user-initiated setup. This behavior enables covert remote control and persistence.
