Hello IT Pros,  

I have collected the Microsoft Endpoint Protection (Microsoft Defender ATP) advanced hunting queries from mdemo, Microsoft Demo and Github for your convenient reference. As we knew, you or your InfoSec Team may need to run a few queries in your daily security monitoring task.  

To save the query 

  • In 

  • go to Advanced hunting and create the query 

  • copy and paste the content, 

  • save them for future re-use 




Query Name 



Search Device Events by IP address 


| where RemoteIP == “”  



List Devices with Schedule Task created by Virus

Github Advanced Hunting Cheat Sheet: 


Query Content 


Find endpoints communicating to a specific domain. 

 Author: @maarten_goet 

let Domain = “”; DeviceNetworkEvents | where Timestamp > ago(7d) and RemoteUrl contains Domain | project Timestamp, DeviceName, RemotePort, RemoteUrl | top 100 by Timestamp desc 


let is the command to introduce variables.  

Variable name: “Domain” 

with value: 

Finds PowerShell execution events that could involve a download. 

Author: @MicrosoftMTP  

union DeviceProcessEvents, DeviceNetworkEvents | where Timestamp > ago(7d) | where FileName in~ (“powershell.exe”, “powershell_ise.exe”) | where ProcessCommandLine has_any(“WebClient”, “DownloadFile”, “DownloadData”, “DownloadString”, “WebRequest”, “Shellcode”, “http”, “https”) | project Timestamp, DeviceName, InitiatingProcessFileName, InitiatingProcessCommandLine, FileName, ProcessCommandLine, RemoteIP, RemoteUrl, RemotePort, RemoteIPType | top 100 by Timestamp 

“union” is the command to combine multiple Device Query Tables 

Find scheduled tasks created by a non-system account 

Author: @maarten_goet 


| where FolderPath endswith “schtasks.exe” and ProcessCommandLine has “/create” and AccountName != “system” 

| where Timestamp > ago(7d) 





Find possible clear text passwords in Windows registry.  

Author: @MicrosoftMTP 


| where ActionType == “RegistryValueSet”  

| where RegistryValueName == “DefaultPassword”  

| where RegistryKey has @”SOFTWAREMicrosoftWindows NTCurrentVersionWinlogon” 

| project Timestamp, DeviceName, RegistryKey | top 100 by Timestamp 


Lookup process executed from binary hidden in Base64 encoded file.  

Author: @MicrosoftMTP 


| where Timestamp > ago(14d) 

| where ProcessCommandLine contains “.decode(‘base64’)” or ProcessCommandLine contains “base64 –decode” or ProcessCommandLine contains “.decode64(“ 

| project Timestamp , DeviceName , FileName , FolderPath , ProcessCommandLine , InitiatingProcessCommandLine  

| top 100 by Timestamp 


Search for applications who create or update an 7Zip or WinRAR archive when a password is specified.  

Author: @PowershellPoet 

DeviceProcessEvents | where ProcessCommandLine matches regex @”s[aukfAUKF]s.*s-p”  

| extend SplitLaunchString = split(ProcessCommandLine, ‘ ‘) 

 | where array_length(SplitLaunchString) >= 5 and SplitLaunchString[1] in~ (‘a’,’u’,’k’,’f’)  

| mv-expand SplitLaunchString  

| where SplitLaunchString startswith “-p”  

| extend ArchivePassword = substring(SplitLaunchString, 2, strlen(SplitLaunchString)) 

 | project-reorder ProcessCommandLine, ArchivePassword  









-p is the password switch and is immediately followed by a password without a space
