If you want to setup the lab on-premise (on your own laptop or in a pre-existing environment), proceed with Option 1. If you want to host it in Microsoft Azure, proceed with Option 2.
Note: if you want to use Azure, you need to have an existing Azure account and cover your own expenses or register a free trial. An Azure subscription is not provided in this lab.
Set up the following three VMs using a hypervisor of your choice.
Hostname | OS | User | Password | Specs |
---|---|---|---|---|
ADSEC-DC | Windows Server 2019 | Administrator | P@ssw0rd123!!! | At least 2 Cores, 4 GB RAM |
ADSEC-00 | Windows Server 2019 | Administrator | P@ssw0rd123! | At least 2 Cores, 4 GB RAM |
ADSEC-01 | Windows Server 2019 | Administrator | P@ssw0rd123! | At least 2 Cores, 4 GB RAM |
Put them all in the same subnet (using an IP range of your choice) and make sure that you have working network connection between the hosts (ping).
Configure the following steps on every VM:
- Point the DNS server to the IP of ADSEC-DC
- Disable Windows Firewall (run in Powershell with admin rights)
Set-NetFirewallProfile -Profile Domain,Public,Private -Enabled False
- Disable Windows Defender
Uninstall-WindowsFeature -Name Windows-Defender
- Download the content of the domain-setup-scripts folder to ADSEC-DC.
- Execute the create-domain.ps1 script on ADSEC-DC. This will make ADSEC-DC the new domain controller of the "contoso.com" domain (shortname = "contoso").
- Reboot ADSEC-DC after setup is done.
Make sure that you can open "DNS Manager" as well as "Active Directory Users and Computers" without any errors popping up.
Join ADSEC-00 and ADSEC-01 to the domain.
Afterwards proceed with #2 Prepare domain
Go through the terraform instructions in this repository activedirectory-lab.
After all VMs are up and running, make sure to disable Windows Defender on all VMs by running:
Uninstall-WindowsFeature -Name Windows-Defender
Afterwards proceed with #2 Prepare domain
Download domainprepare.ps1 and domainprepare.json to ADSEC-DC and make sure to save them to the same folder. cd
into that folder and execute domainprepare.ps1.
cd <whatever-directory-you-choose>
cat -raw .\domainprepare.ps1 | iex
This script will populate AD with users, groups and OUs for the exercise.
- Add the domain user "john" to the local "Administrators" group on ADSEC-00. Try to login with John at least once to make sure that authentication works as expected.
- Add the domain user "blee" to the local "Administrators" group on ADSEC-01. Try to login with Bruce Lee at least once to make sure that authentication works as expected.
Display Name | samAccountName | Password |
---|---|---|
John Doe | john | P@ssw0rd |
Bruce Lee | blee | TekkenIsAwesome! |
In this scenario, we assume that the user "john" and his client ADSEC-00 have been already compromised by the attacker. Please prepare ADSEC-00 as described below:
- Download the attacker-tools zip files and extract the tools to
C:\attacker-tools
on ADSEC-00 (Note: the password is "infected"). - Install neo4j community edition on ADSEC-00 (we’ll need this later for Bloodhound). The attacker-tools.zip contains a script called
install-neo4j.ps1
. Just run this with admin privileges and it will install neo4j and Firefox via the chocolatey package manager. - After successful installation, open Firefox and navigate to the neo4j web interface at https://127.0.0.1:7474/browser/. Log in with the default credentials (neo4j/neo4j) and choose a new password for the neo4j user. This step is mandatory, otherwise we can't use Bloodhound later on so make sure that you remember the password.
- You may also want to install a text editor of your choice.
