How to get Antivirus-related Data from Microsoft Defender for Endpoint using Intune and Graph API

How to get Antivirus-related Data from Microsoft Defender for Endpoint using Intune and Graph API. Hello everyone! In this episode, I would like to tell you how I tried to get automatically antivirus-related data (current status, engine and signature version, last full scan date) from Microsoft Defender for Endpoint using Microsoft Intune and the Graph API.

Why is this necessary?

You might assume that if the Defender for Endpoint agent is installed on the host, everything should be fine automatically. But in fact, the antivirus engine and signature versions may be outdated, real-time protection may be disabled. And so all this needs to be monitored.

Grapf API

This will be the third episode about Microsoft Enterprise Security APIs. The first was about Defender and Defender API, the second was about Intune and the Intune API. And today I’m going to talk about the Grapf API, which should probably replace all the other APIs and should be more logical and easier. Although in my opinion it is even strangier and poorly documented. I didn’t like it.

Last Week’s Security news: PrintNightmare, Kaseya, Intune, Metasploit Docker escape

Last Week’s Security news: PrintNightmare, Kaseya, Intune, Metasploit Docker escape. Hello guys! The second episode of Last Week’s Security news from June 28 to July 4.

The most interesting vulnerability of the last week is of course Microsoft Print Spooler “PrintNightmare”. By sending an RpcAddPrinterDriverEx() RPC request, for example over SMB, a remote, authenticated attacker may be able to execute arbitrary code with SYSTEM privileges on a vulnerable Windows system. And there is a public PoC exploit for this vulnerability published by the Chinese security firm Sangfor. And there is some strange story. It turns out that Sangfor published an exploit for the 0day vulnerability. But they thought this vulnerability (CVE-2021-1675) had already been patched as part of the June Micorosft Patch Tuesday. And then it turns out that this is a bug in the Microsoft patch. But Microsoft wrote that this is a different, new vulnerability CVE-2021-34527 and so there were no problems with the previous patch. In any case, a patch for this vulnerability has not yet been released and Microsoft is suggesting two Workarounds. Option 1 – Disable the Print Spooler service, Option 2 – Disable inbound remote printing through Group Policy. Do this first for Domain Controllers and other critical Windows servers. All versions of Windows contain the vulnerable code and are susceptible to exploitation. Also note that the new vulnerability has a flag Exploitation Detected on the MS site.

Getting Hosts from Microsoft Intune MDM using Python

8 Replies

Getting Hosts from Microsoft Intune MDM using Python. Today I want to talk about Microsoft Intune. It is a Mobile Device Management platform.

Well, I think that the importance of MDM systems has become much higher than it was before the days of covid-19. Simply because a lot more people now work remotely using corporate laptops. And if these people don’t connect to the corporate network using a VPN, you most likely won’t see any activity from their devices in Active Directory. This means that you will not understand whether the device is active or not. And it will be impossible to get the correct security metrics for these devices.

Mobile device management is a solution to this problem as it maintains a connection between the laptop and the cloud server. MDM can collect various parameters from hosts, but for me the most important parameter is the timestamp. I will not describe all the features of Microsoft Intune here. Simply because at this stage they are not very interesting to me. The task I needed to solve was how to get the timestamp of the last activity for all hosts in Microsoft Intune using the official API. And since this is poorly documented, I want to share it with you.
