Description¶
A threat actor might want to add an owner to an Azure AD application via Microsoft Graph APIs and the right permissions.
Run Simulation¶
Get OAuth Access Token¶
from msal import PublicClientApplication
import requests
import time
function_app_url = "https://FUNCTION_APP_NAME.azurewebsites.net"
tenant_id = "TENANT_ID"
public_client_app_id = "KATANA_CLIENT_APP_ID"
server_app_id_uri = "api://" + tenant_id + "/cloudkatana"
scope = server_app_id_uri + "/user_impersonation"
app = PublicClientApplication(
public_client_app_id,
authority="https://login.microsoftonline.com/" + tenant_id
)
result = app.acquire_token_interactive(scopes=[scope])
bearer_token = result['access_token']
Set Azure Function Orchestrator¶
endpoint = function_app_url + "/api/orchestrators/Orchestrator"
Prepare HTTP Body¶
data = [{'RequestId': '33a76f7e-619b-4fa2-a13e-776cc93a2c72', 'name': 'Add New Owner to Azure AD Application', 'metadata': {'creationDate': '2021-08-05', 'modificationDate': '2021-09-08', 'description': 'A threat actor might want to add an owner to an Azure AD application via Microsoft Graph APIs and the right permissions.\n', 'contributors': ['Roberto Rodriguez @Cyb3rWard0g', 'MSTIC R&D'], 'mitreAttack': [{'technique': 'T1098.001', 'tactics': ['TA0003']}]}, 'steps': [{'schema': 'atomic', 'id': '54169cc7-baf0-40b0-8431-89add22356fb', 'name': 'Add New Owner to Azure AD Application', 'metadata': {'creationDate': '2021-08-05', 'modificationDate': '2021-09-08', 'description': 'A threat actor might want to add an owner to an Azure AD application via Microsoft Graph APIs and the right permissions.\n', 'contributors': ['Roberto Rodriguez @Cyb3rWard0g', 'MSTIC R&D'], 'mitreAttack': [{'technique': 'T1098.001', 'tactics': ['TA0003']}]}, 'authorization': [{'resource': 'https://graph.microsoft.com/', 'permissionsType': 'application', 'permissions': ['Application.ReadWrite.All', 'Directory.Read.All']}], 'execution': {'type': 'ScriptModule', 'platform': 'Azure', 'executor': 'PowerShell', 'module': {'name': 'CloudKatanaAbilities', 'version': 1.0, 'function': 'Add-CKOwnerToAzADApp'}, 'parameters': {}}, 'number': 1}]}]
Send HTTP Request¶
http_headers = {'Authorization': 'Bearer ' + bearer_token, 'Accept': 'application/json','Content-Type': 'application/json'}
results = requests.get(endpoint, json=data, headers=http_headers, stream=False).json()
time.sleep(30)
Explore Output¶
query_status = requests.get(results['statusQueryGetUri'], headers=http_headers, stream=False).json()
query_results = query_status['output']
query_results
