Run advanced queries using PowerShell, see Advanced Hunting API.

In this section, we share PowerShell samples to retrieve a token and use it to run a query.

Before you begin

You first need to create an app.

Preparation instructions

• Open a PowerShell window.
• If your policy does not allow you to run the PowerShell commands, you can run the below command:

  Set-ExecutionPolicy -ExecutionPolicy Bypass
  

For more information, see PowerShell documentation

Get token

• Run the following:

$tenantId = '00000000-0000-0000-0000-000000000000' # Paste your own tenant ID here
$appId = '11111111-1111-1111-1111-111111111111' # Paste your own app ID here
$appSecret = '22222222-2222-2222-2222-222222222222' # Paste your own app secret here

$resourceAppIdUri = 'https://api.securitycenter.microsoft.com'
$oAuthUri = "https://login.microsoftonline.com/$TenantId/oauth2/token"
$body = [Ordered] @{
    resource = "$resourceAppIdUri"
    client_id = "$appId"
    client_secret = "$appSecret"
    grant_type = 'client_credentials'
}
$response = Invoke-RestMethod -Method Post -Uri $oAuthUri -Body $body -ErrorAction Stop
$aadToken = $response.access_token

where

• $tenantId: ID of the tenant on behalf of which you want to run the query (that is, the query will be run on the data of this tenant)
• $appId: ID of your Azure AD app (the app must have 'Run advanced queries' permission to Defender for Endpoint)
• $appSecret: Secret of your Azure AD app

Run query

Run the following query:

$query = 'RegistryEvents | limit 10' # Paste your own query here

$url = "https://api.securitycenter.microsoft.com/api/advancedqueries/run"
$headers = @{ 
    'Content-Type' = 'application/json'
    Accept = 'application/json'
    Authorization = "Bearer $aadToken" 
}
$body = ConvertTo-Json -InputObject @{ 'Query' = $query }
$webResponse = Invoke-WebRequest -Method Post -Uri $url -Headers $headers -Body $body -ErrorAction Stop
$response =  $webResponse | ConvertFrom-Json
$results = $response.Results
$schema = $response.Schema

• $results contain the results of your query
• $schema contains the schema of the results of your query

Complex queries

If you want to run complex queries (or multilines queries), save your query in a file and, instead of the first line in the above sample, run the below command:

$query = [IO.File]::ReadAllText("C:\myQuery.txt"); # Replace with the path to your file

Work with query results

You can now use the query results.

To output the results of the query in CSV format in file file1.csv do the below:

$results | ConvertTo-Csv -NoTypeInformation | Set-Content file1.csv

To output the results of the query in JSON format in file file1.json do the below:

$results | ConvertTo-Json | Set-Content file1.json
