## Defender XDR
```KQL
let CompromisedDevices = dynamic (["workstation01", "server1"]);
let SearchWindow = 7d; //Customizable h = hours, d = days
DeviceRegistryEvents
| where Timestamp > ago(SearchWindow)
| where DeviceName has_any (CompromisedDevices)
| where RegistryKey endswith @'\Software\Microsoft\Windows\CurrentVersion\Run' or  RegistryKey endswith @'\Microsoft\Windows\CurrentVersion\RunOnce'
| project-reorder Timestamp, ActionType, DeviceId, DeviceName, RegistryKey, PreviousRegistryValueData, InitiatingProcessCommandLine
```
