Live Response to remote device

Live response gives you the remote access to target device by remote shell connection. It enables security admin to run command, script and collect forensic data,  send suspicious entities for analysis, remediate threats, and proactively hunt for emerging threats on the remote device. 

To Enable Live Response for ATP devices: 

  • In ATP Portal, go to SettingsGeneralAdvanced features

Advanced commands 

The following advanced commands are for the user roles that are granted the ability to run advanced live response commands such as ATP Administrator Role: 

analyzeAnalyses the entity with various incrimination engines to reach a verdict.
getfileGets a file from the device. (3GB max size limit) 
NOTE: This command has a prerequisite command. You can use the -auto command in conjunction with getfile to automatically run the prerequisite command.
runRuns a PowerShell script from the library on the device.

– Process: stop, delete image file 
– Service: stop, delete image file 
– Registry entry: delete 
– Scheduled task: remove 
– Startup folder item: delete file 
NOTE: This command has a prerequisite command. You can use the -auto command in conjunction with remediate to automatically run the prerequisite command.
undoRestores an entity that was remediated.

To run Powershell Script in live response: 

The library stores files (such as ) that can be run in a live response session at the tenant level. PowerShell must first be placed in the library before you can run them. 

Upload the script file in the library and run script

Click Upload file to library.

  • Click Browse and select the file. 
  • Provide a brief description. 
  • Specify if you'd like to overwrite a file with the same name. 
  • If you'd like to be known what parameters are needed for the script, select the script parameters check box. In the text field, enter an example and a description. 
  • Click Confirm. 
  • (Optional) To verify that the file was uploaded to the library, run the library command. 
  • Run the script with command: Run scriptname.ps1 

Cancel a command 

Anytime during a session, you can cancel a command by pressing CTRL + C. 

Using this shortcut will not stop the command in the agent side. It will only cancel the command in the portal.  

Automatically run prerequisite commands 

Some commands have prerequisite command's to run parallelly. If you don't run the prerequisite command, you would get an error. For example, running the download command without fileinfo will return an error. 

You can use the auto flag to automatically run prerequisite commands,: 

getfile c:UsersuserDesktopwork.txt -auto  

Apply command parameters 

When using commands that have prerequisite commands, you can use flags: 

-type file -id – auto  

Supported output types 

Live response supports table and JSON format output types. For each command, there's a default output behavior. You can modify the output in your preferred output format using the following commands: 

  • -output json 
  • -output table 


Fewer fields are shown in table format due to the limited space. To see more details in the output, you can use the JSON output command so that more details are shown. 

View the command log 

Select the Command log tab to see the commands used on the device during a session. Each command is tracked with full details, ID, Command line, Duration, Status and input or output side bar 


  • Analyze a file 

     analyze -type file -id C:UsersCMAdmin.FourthCoffeeDownloadsKnownMalicious.exe -auto


  • Analyze File in remote machine and Auto Download to local Workstation in the “Downloads” Folder: 

analyze -type file -id C:UsersCMAdmin.FourthCoffeeDownloadsKnownMalicious.exe -auto > AnalyzedKnownMalicious.txt 

  • Remediating a file (delete file) 

C:>remediate -type file -id C:UsersCMAdmin.FourthCoffeeDownloadsFreeVideo.exe -auto 


C:>remediate file C:UsersCMAdmin.FourthCoffeeDownloadsFreeVideo.exe -auto 

  • To download file from the remote target device to your local workstation 

C:getfile “C:UsersCMAdmin.FourthCoffeeDownloadsFreeVideo.exe” -auto 


C:> download “C:UsersCMAdmin.FourthCoffeeDownloadsFreeVideo.exe” -auto 

  • To list on connection of the remote target device 

C:> connections 

  • To list the registry key and value of the remote target device 

C:> registry “HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Defender” 

  • Creating a test script, upload to Library and run script: 

Example: creating ATPTest.ps1 with the following content: 

Dir c:usersCMAdmin.Contoso.comdownloads > C:tempdowload_files.txt 

Upload script named “ATPTest.ps1” to Library and run the script 


Download result of run content to your local workstation under “downloads” folder 

Download “C:Tempdownload_files.txt” -auto 


I hope the information is useful to your daily ATP operation monitoring.
