 # Learn the advanced hunting query language
@@ -32,64 +31,87 @@ Advanced hunting is based on the [Kusto query language](https://docs.microsoft.c
 In Microsoft Defender Security Center, go to **Advanced hunting** to run your first query. Use the following example:
 
 ```kusto
-// Finds PowerShell execution events that could involve a download.
+// Finds PowerShell execution events that could involve a download
-DeviceProcessEvents  
+union DeviceProcessEvents, DeviceNetworkEvents
 | where Timestamp > ago(7d)
-| where FileName in ("powershell.exe", "POWERSHELL.EXE", "powershell_ise.exe", "POWERSHELL_ISE.EXE") 
+// Pivoting on PowerShell processes
-| where ProcessCommandLine has "Net.WebClient"
+| where FileName in~ ("powershell.exe", "powershell_ise.exe")
-        or ProcessCommandLine has "DownloadFile"
+// Suspicious commands
-        or ProcessCommandLine has "Invoke-WebRequest"
+| where ProcessCommandLine has_any("WebClient",
-        or ProcessCommandLine has "Invoke-Shellcode"
+    "DownloadFile",
-        or ProcessCommandLine contains "http:"
+    "DownloadData",
-| project Timestamp, DeviceName, InitiatingProcessFileName, FileName, ProcessCommandLine
+    "DownloadString",
+    "WebRequest",
+    "Shellcode",
+    "http",
+    "https")
+| project Timestamp, DeviceName, InitiatingProcessFileName, InitiatingProcessCommandLine, 
+FileName, ProcessCommandLine, RemoteIP, RemoteUrl, RemotePort, RemoteIPType
 | top 100 by Timestamp
 ```
 
 This is how it will look like in advanced hunting.

-### Describe the query and specify the table to search
+
-The query starts with a short comment describing what it is for. This helps if you later decide to save your query and share it with others in your organization.

-The query itself will typically start with a table name followed by a series of elements started by a pipe (`|`). In this example, we start by adding  with the table name `DeviceProcessEvents` and add piped elements as needed.
+The query itself will typically start with a table name followed by a series of elements started by a pipe (`|`). In this example, we start by creating a union of two tables,  `DeviceProcessEvents` and `DeviceNetworkEvents`, and add piped elements as needed.
 
+```kusto
+union DeviceProcessEvents, DeviceNetworkEvents
+```
 ### Set the time range
-The first piped element is a time filter scoped within the previous seven days. Keeping the time range as narrow as possible ensures that queries perform well, return manageable results, and don't time out.

 ```kusto
 | where Timestamp > ago(7d)
 ```
-### Search for specific executable files
-The time range is immediately followed by a search for files representing the PowerShell application.
 
-```kusto
+### Check specific processes
-| where FileName in ("powershell.exe", "POWERSHELL.EXE", "powershell_ise.exe", "POWERSHELL_ISE.EXE")
+The time range is immediately followed by a search for process file names representing the PowerShell application.
+
 ```
-### Search for specific command lines
+// Pivoting on PowerShell processes
-Afterwards, the query looks for command lines that are typically used with PowerShell to download files.

-
-```kusto
-| where ProcessCommandLine has "Net.WebClient"
-        or ProcessCommandLine has "DownloadFile"
-        or ProcessCommandLine has "Invoke-WebRequest"
-        or ProcessCommandLine has "Invoke-Shellcode"
-        or ProcessCommandLine contains "http:"
 ```
-### Select result columns and length 
+
-Now that your query clearly identifies the data you want to locate, you can add elements that define what the results look like. `project` returns specific columns and `top` limits the number of results, making the results well-formatted and reasonably large and easy to process.
+### Search for specific command strings
+Afterwards, the query looks for strings in command lines that are typically used to download files using PowerShell.
 
 ```kusto
-| project Timestamp, DeviceName, InitiatingProcessFileName, FileName, ProcessCommandLine
+// Suspicious commands
+| where ProcessCommandLine has_any("WebClient",
+    "DownloadFile",
+    "DownloadData",
+    "DownloadString",
+    "WebRequest",
+    "Shellcode",
+    "http",
+    "https")
+```
+
+### Customize result columns and length 
+Now that your query clearly identifies the data you want to locate, you can add elements that define what the results look like. `project` returns specific columns, and `top` limits the number of results. These operators help ensure the results are well-formatted and reasonably large and easy to process.

+```kusto
+| project Timestamp, DeviceName, InitiatingProcessFileName, InitiatingProcessCommandLine, 
+FileName, ProcessCommandLine, RemoteIP, RemoteUrl, RemotePort, RemoteIPType
 | top 100 by Timestamp
 ```
