Onboarding Linux Client (DEEPIN) to Microsoft Azure Threat protection ATP using ubuntu repository

Installing Microsoft Azure Threat Protection (ATP) on Linux Devices

While playing with ATP on some windows devices, I was in the mood of trying the new Deepin 20 desktop flavor which is a famous Chinese Linux OS based system.

Microsoft doesn’t indicate anywhere that installation of ATP on a Linux client is possible but Linux server is mentioned in the official ATP installation documents.

How to Install?

After I installed the Deepin OS, I was really impressed by the new beautiful Linux design so I plan to use it and have it secure with ATP.

Prerequisites:

  1. Configure the Linux software repository for Ubuntu and Debian
  2. Application Installation
  3. Download the onboarding Package
  4. Client Config

1-Configure the Linux software repository for Ubuntu and Debian

You will need to install the required libraries, install Gpg, apt-transport-https and update repository metadata using the following commands one by one.

  • sudo apt-get install curl

image

  • sudo apt-get install libplist-utils

image

image

  • sudo mv ./microsoft.list /etc/apt/sources.list.d/microsoft-ubuntu.list
  • sudo apt-get install gpg

image

image

image

After successfully installing all the libraries, I will go ahead and install the application

2- Application Installation

From the Linux client Terminal using sudo power user run the following script

sudo apt-get install mdatp

image

Once finished, You can go back to the ATP portal and download the Linux Onboarding package on the linux server/client you want to onboard

3- Download the onboarding Package

Since I am doing a single deployment not bulk, then I will go to the Microsoft Defender Security Center’s setting page and download the Linux package from the device management section.

image

The steps for the onboarding is already mentioned on that page so after you download the script you’ll know exactly what to do next.

The file is 9kb python in size

image

Copy the file to your Linux Desktop

image

4- Client Config

From the terminal type in chmod a+x MicrosoftDefenderATPOnBoardingLinuxServer.py and hit enter

Note: python must be installed on this linux dervice.

Then type python /MicrosoftDefenderATPOnBoardingLinuxServer.py

image

This will run pretty quick and will assign your Linux server/client with your Organization ID.

To see the Organization ID type:

mdatp –health orgId

image

Few minutes later you’ll be able to see the installation completion and the status through this command

Check if WDATP is functioning as expected

mdatp –health healthy

image

Check if WDATP agent is enabled

mdatp –health realTimeProtectionEnabled

image

Let’s check on our ATP portal and see if the machine is showing there.

Note: It might take 5-15 mins to update the definitions of WDATP when onboarding.

image

Running a detection Test:

curl -o ~/Downloads/eicar.com.txt https://www.eicar.org/download/eicar.com.txt

image

In few seconds the file has disappeared

image

Checking for threats

mdatp –threat –list –pretty

image

Let’s see this on the ATP Portal

This is just a test malware not a real one therefore it wont harm your machine at all.

Hope this helps you with your deployments

Deepin 20 Beta version

https://www.deepin.org/en/2020/04/15/deepin-20-beta/

Resetting Root Password for FreePBX 14.0.5.1–Sangoma Linux 7

Many people have been through this same problem either due to forgetting the root password, typing it wrong or due to console language conversion issue.

Mine was due to using a remote console which didn’t translate my keyboard properly and caused a wrong password.

So I ended up having access to the GUI screen but not the root. So first thing came to my mind is should I reformat the machine and reinstall it since it doesn’t take long time? but no I like challenges and started digging into how do I reset the password.

Since I do still have the access to console I can try from the Kernel, the default ISO install FreePBX with Sangoma 7 Distro which is based on Centos Kernel 3.10.0-862.2.2.3 el7.x86_64.

So I first attempt I tried was following the same method of resetting root password on Centos through Kernel.

1- Restarting the machine to get into Kernel:

When Restarting Press E to edit the Kernel

image

Once pressed E you will get this screen:

image

2- Edit the Kernel:

Scroll down until you find “rhgb quiet” and replace it with “init=/bin/bash” without quotes.

image

So eventually it’ll look like this

image

3- Resetting Root Password:

Once it’s changed, press ctrl-X to initiate the process of resetting the root password:

You will get Bash cmd prompt, Type the following commands

A- First to check the status of root partition by running following command on the single user mode.

Mount | grep root

In this distro of Linux you might not get anything but normally you should get partition details.

B- To make the partition writable, you’ll have to type in the following command

mount -o remount,rw /

C- To Change the root password type

passwd root

Type your new password and you’ll get a message that all authentication tokens updated successfully

After this restart and try to login, and you’ll see that it works fine

Result:

After restarting the machine, I tried to get into web GUI to start configuring the FreePBX but I received the following error:

Whoops\Exception\ErrorException (E_ERROR)

Class ‘PicoFeed\Reader\Reader’ not found

After doing some research it was obviously an error related to a recent update pushed by FreePBX

Solution:

and the solution was running this cmd

fwconsole ma upgrade dashboard –edge

Change WordPress Domain using http://wp-cli.org/

  1. sudo curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

clip_image001

  1. From User@UbuntuServer:/var/www/html$ I will run the following command to make sure that the command is working

sudo php wp-cli.phar –info

clip_image002

  1. I’ll move the file to a new path and location so I can access it from anywhere using only the command WP.

First I will give the required permissions

moh10ly@Ubunut-Mohammed:/var/www/html$ sudo chmod +x wp-cli.phar

clip_image003

Next I will move the file

sudo mv wp-cli.phar /usr//local/bin/wp

clip_image004

  1. Check if the file is working properly after moving?

clip_image005

  1. Final step is to change the domain of your wordpress site to a new domain.

My previous domain was www.mytechweb.ga and now I changed it to www.moh10ly.website

So I only used two commands to change the domain name to the new one

5- OneDrive for Linux.

http://xmodulo.com/sync-microsoft-onedrive-linux.html

Install onedrive-d on Linux

While onedrive-d was originally developed for Ubuntu/Debian, it now supports CentOS/Fedora/RHEL as well.

Installation is as easy as typing the following.

$ git clone https://github.com/xybu92/onedrive-d.git
$ cd onedrive-d
$ ./inst install

First-Time Configuration

After installation, you need to go through one-time configuration which involves granting onedrive-d read/write access to your OneDrive account.

First, create a local folder which will be used to sync against a remote OneDrive account.

$ mkdir ~/onedrive

Then run the following command to start the first-time configuration.

$ onedrive-d

It will pop up a onedrive-d’s Settings window as shown below. In "Location" option, choose the local folder you created earlier. In "Authentication" option, you will see "You have not authenticated OneDrive-d yet" message. Now click on "Connect to OneDrive.com" box.

clip_image008

It will pop up a new window asking you to sign in to OneDrive.com.

clip_image009

After logging in to OneDrive.com, you will be asked to grant access to onedrive-d. Choose "Yes".

clip_image010

Coming back to the Settings window, you will see that the previous status has changed to "You have connected to OneDrive.com". Click on "OK" to finish.

clip_image011

Sync a Local Folder with OneDrive

There are two ways to sync a local folder with your OneDrive storage by using onedrive-d.

One way is to sync with OneDrive manually from the command line. That is, whenever you want to sync a local folder against your OneDrive account, simply run:

$ onedrive-d

onedrive-d will then scan the content of both a local folder and a OneDrive account, and make the two in sync. This means either uploading newly added files in a local folder, or downloading newly found files from a remote OneDrive account. If you remove any file from a local folder, the corresponding file will automatically be deleted from a OneDrive account after sync. The same thing will happen in the reverse direction as well.

Once sync is completed, you can kill the foreground-running onedrive-d process by pressing Ctrl+C.

clip_image012

Another way is to run onedrive-d as an always-on daemon which launches automatically upon start. In that case, the background daemon will monitor both the local folder and OneDrive account, to keep them in sync. For that, simply add onedrive-d to the auto-start program list of your desktop.

When onedrive-d daemon is running in the background, you will see OneDrive icon in the desktop status bar as shown below. Whenever sync update is triggered, you will see a desktop notification.

6- Evolution Email Client for Exchange accounts.

If you ever thought of using an e-mail client that supports your account on Microsoft Exchange Email server’s protocol which is known as (RPC over HTTP) then you have probably used Mozilla thunderbird or kmail, geary..etc but all those clients don’t support Exchange’s most flexible connectivity which is RPC over HTTP that will sync all your emails, contacts, tasks, calendars ..etc

To Install evolution, all you have to do is open Linux Terminal and type the following

Sudo apt-get install evolution

clip_image014

Since I already have Evolution installed it won’t proceed and will tell me that it’s already installed. but that’s not all!

In order to setup an Exchange account on Evolution you will have to install an Evolution plugin that will support the web services for the RPC over http connectivity which is known as (EWS = Exchange Web Services).

In order to install this plugin you will have to type the following command

Sudo apt-get install Evolution-ews

clip_image015

Once you install the plugin, you can launch the program and setup your account as following.

Click on Add as in the picture

clip_image016

When you click add you should be welcomed by a message saying "Welcome to Evolution wizard ..etd"

Click Continue and then type in your name and email address in the next window

You can skip the automatic configuration as Evolution still doesn’t support Exchange Autodiscover mechanism for auto configuration of the account. so you must manually provide all the configuration of your exchange as following

clip_image017

In the host URL you will have to provide your Exchange server’s EWS URL which usually looks like this

https://mail.domain.com/ews/exchange.asmx

In my case I am using an Office 365 account so instead I’ll use Microsoft’s EWS url.

https://outlook.office365.com/ews/exchange.asmx

For the OAB (Offline Address Book) you also need to provide the configured URL of the OAB on your Exchange Server. which in my case again it’s Microsoft Office 365.

https://outlook.office365.com/OAB

you will need to make sure that the correct authentication method is set (NTLM) in my case, this can vary though on Exchange server’s Outlook Anywhere configuration. it can be Basic as well. so it’s up to your configuration to choose but for Office 365 it’s NTLM.

clip_image018

Once you finish the configuration you can continue and you’ll get prompted to enter your Credentials. as soon as you finish typing your Password hit enter and your e-mails will start syncing. as in the following snapshot

clip_image019

That’s it, you’re setup here either if it’s an exchange on-premises or Office 365 for Linux desktop client.

Here’s another guide for the new mapi connectivity for Evolution, probably the same steps

7- For Office (Word, Powerpoint ..etc) I prefer to use Kingsoft’s community version along with LibreOffice

Since Libre office provide more tools or the full package I still use it on Linux but Kingsoft’s WPS tools have a user friendly and rich of tools GUI.

clip_image020

In order to download WPS software you will have to navigate to the link below and download the suitable version with your Linux OS. or use the terminal to download latest available version with the following command

sudo apt-get install wps-office

http://wps-community.org/download.html

8- For media there are various available software and tools that you can use on Linux to either listen to music or edit mp3s or convert media types.

A- Audacity (Convert and Edit audio files).

B- Spotify (listen to music online)

C- Clementine (Listen to Music on your computer)

D- VLC (Watch Videos on your PC) or use it as a streaming server.

There are other useful tools and things to do on Linux OS as it’s a very flexible and customizable OS but I’ll end this article here and write a new one about how to decorate your welcome screen and your desktop with beautiful pictures and tools.

Hope you find this useful Smile
