MDE ‐ Live Response Overview
I have been asked a couple of times now about how to use live response and the benefit of it. In my opinion, live response is great for getting on an endpoint collecting data or correcting situations.
Top customer situations:
- Need to kick off an antivirus scan(you could use the console also)
- Need to make a configuration change on the endpoint
- Need to remotely wipe the machine(this is assuming you don't want or don't have Intune)
- Remove a device from MDE Management
- Download a file from an endpoint
- Live Reponse Configured
- PowerShell Scripts or knowledge to create them
To access Live Response, you will need to navigate to the device, Device Inventory is a one of the locations. Click on the ellipses and click on Initiate Live Response.
You can upload PowerShell scripts to your tenant library in the top right corner.
For the most recent commands, please view them here.
The script for this is pretty easy:
cd 'C:\Program Files\Windows Defender\' .\MpCmdRun.exe -scan -scantype 1
I'm kicking off a quick scan, but you can do whichever you need(documentation below).
Now that we have the script, save it and upload it to your library.
Validate the script was uploaded using the library command to list all your files.
Upload the file to the endpoint: putfile RunQuickScan.ps1
You should get this once its done.
