title: Windows Incoming AnyDesk Connection via AnyDesk.exe or AnyDeskMSI.exe
id: 6c47eead-f337-43b2-b809-551892443775
status: experimental
description: This rule flags network connections where the process image ends with AnyDesk.exe or AnyDeskMSI.exe and the connection is marked as incoming (Initiated is false). Incoming AnyDesk connections can indicate an external actor reaching a listening remote access component to establish a command-and-control path. The detection relies on Windows network connection telemetry that includes the initiating status and the process image path.

  - Legitimate incoming connections (e.g. sysadmin activity). Most of the time I would expect outgoing connections (initiated locally).
