Game of Active Directory (GOAD) - SCCM

Props!

Huge shout out to @M4yFly for all the hard work to create GOAD SCCM, and Errorix404 on the Ludus Discord for getting GOAD SCCM to work with Ludus!

GOAD SCCM Network Map

1. Add the Windows 2019 template to Ludus

git clone https://gitlab.com/badsectorlabs/ludus
cd ludus/templates
ludus templates add -d win2019-server-x64
[INFO]  Successfully added template
ludus templates build
[INFO]  Template building started - this will take a while. Building 1 template(s) at a time.
# Wait until the templates finish building, you can monitor them with `ludus templates logs -f` or `ludus templates status`
ludus templates list
+----------------------------------------+-------+
|                TEMPLATE                | BUILT |
+----------------------------------------+-------+
| debian-11-x64-server-template          | TRUE  |
| debian-12-x64-server-template          | TRUE  |
| kali-x64-desktop-template              | TRUE  |
| win11-22h2-x64-enterprise-template     | TRUE  |
| win2022-server-x64-template            | TRUE  |
| win2019-server-x64-template            | TRUE  |
+----------------------------------------+-------+

2. Set and deploy the following range configuration

config.yml
ludus:
  - vm_name: "{{ range_id }}-SCCM-DC"
    hostname: "{{ range_id }}-DC01"
    template: win2019-server-x64-template
    vlan: 10
    ip_last_octet: 40
    ram_gb: 4
    cpus: 2
    windows:
      sysprep: true
  - vm_name: "{{ range_id }}-SCCM-MECM"
    hostname: "{{ range_id }}-SRV01"
    template: win2019-server-x64-template
    vlan: 10
    ip_last_octet: 41
    ram_gb: 4
    cpus: 2
    windows:
      sysprep: true
  - vm_name: "{{ range_id }}-SCCM-MSSQL"
    hostname: "{{ range_id }}-SRV02"
    template: win2019-server-x64-template
    vlan: 10
    ip_last_octet: 42
    ram_gb: 4
    cpus: 4
    windows:
      sysprep: true
  - vm_name: "{{ range_id }}-SCCM-CLIENT"
    hostname: "{{ range_id }}-WS01"
    template: win2019-server-x64-template
    vlan: 10
    ip_last_octet: 43
    ram_gb: 4
    cpus: 2
    windows:
      sysprep: true
  - vm_name: "{{ range_id }}-kali"
    hostname: "{{ range_id }}-kali"
    template: kali-x64-desktop-template
    vlan: 10
    ip_last_octet: 99
    ram_gb: 4
    cpus: 4
    linux: true
    testing:
      snapshot: false
      block_internet: false

vim config.yml
# paste in the config above (adjust cpus and ram_gb values if you have the resources to allocate more)
ludus range config set -f config.yml
ludus range deploy
# Wait for the range to successfully deploy
# You can watch the logs with `ludus range logs -f`
# Or check the status with `ludus range status`

3. Install ansible and its requirements for GOAD on your local machine

# You can use a virtualenv here if you would like
python3 -m pip install ansible-core
python3 -m pip install pywinrm
git clone https://github.com/Orange-Cyberdefense/GOAD
cd GOAD/ansible
ansible-galaxy install -r requirements.yml

4. Create the following inventory file and replace RANGENUMBER with your range number with sed (commands provided below)

inventory.yml
[default]
; Note: ansible_host *MUST* be an IPv4 address or setting things like DNS
; servers will break.
; ------------------------------------------------
; sccm.lab
; ------------------------------------------------
dc01 ansible_host=10.RANGENUMBER.10.40 dns_domain=dc01 dict_key=dc01
srv01 ansible_host=10.RANGENUMBER.10.41 dns_domain=dc01 dict_key=srv01
srv02 ansible_host=10.RANGENUMBER.10.42 dns_domain=dc01 dict_key=srv02
ws01 ansible_host=10.RANGENUMBER.10.43 dns_domain=dc01 dict_key=ws01

[all:vars]
force_dns_server=yes
dns_server=10.RANGENUMBER.10.254

two_adapters=no
; adapter created by proxmox (change them if you get an error)
; to get the name connect to one vm and run ipconfig it will show you the adapters name
nat_adapter=Ethernet
domain_adapter=Ethernet

; winrm connection (windows)
ansible_user=localuser
ansible_password=password
ansible_connection=winrm
ansible_winrm_server_cert_validation=ignore
ansible_winrm_operation_timeout_sec=400
ansible_winrm_read_timeout_sec=500

Linux
macOS

vim inventory.yml
# paste in the inventory file above
export RANGENUMBER=$(ludus range list --json | jq '.rangeNumber')
# `sudo apt install jq` if you don't have jq
sed -i "s/RANGENUMBER/$RANGENUMBER/g" inventory.yml

vim inventory.yml
# paste in the inventory file above
export RANGENUMBER=$(ludus range list --json | jq '.rangeNumber')
# `brew install jq` if you don't have jq
sed -i '' "s/RANGENUMBER/$RANGENUMBER/g" inventory.yml

5. Edit GOAD Ansible

Edit GOAD/ansible/roles/sccm/install/mecm/tasks/main.yml and add these three tasks to the top of the file:

- name: create directory to store the downloaded prerequisite files
  ansible.windows.win_file:
    path: C:\setup
    state: directory

- name: Download Visual C++ 2017 Redistributable
  ansible.windows.win_get_url:
    url: https://aka.ms/vs/15/release/vc_redist.x64.exe
    dest: C:\setup\vc_redist.x64.exe
  register: download_vc_redist

- name: Install Visual C++ 2017 Redistributable
  ansible.windows.win_package:
    path: C:\setup\vc_redist.x64.exe
    arguments: /quiet /norestart
  when: download_vc_redist.changed

6. Deploy GOAD

note

You must be connected to your Ludus wireguard VPN for these commands to work

Linux
macOS

vim build.yml
# Edit the keyboard layout to your preferred layout (or remove that whole line)
export ANSIBLE_COMMAND="ansible-playbook -i ../ad/SCCM/data/inventory -i ./inventory.yml"
export LAB="SCCM"
../scripts/provisionning.sh

vim build.yml
# Edit the keyboard layout to your preferred layout (or remove that whole line)
export ANSIBLE_COMMAND="ansible-playbook -i ../ad/SCCM/data/inventory -i ./inventory.yml"
export LAB="SCCM"
export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES
../scripts/provisionning.sh

Now you wait. [WARNING] lines are ok, and some steps may take a long time, don't panic!

This will take a few hours. You'll know it is done when you see:

your lab : SCCM is successfully setup ! have fun ;)

Install .Net Framework 3.5 with DISM Error

If you encounter errors with TASK [sccm/install/iis : Install .Net Framework 3.5 with DISM] or similar, update the failing machine with ludus:

ludus testing update -n JD-SCCM-MECM # Replace JD with your UserID
# Wait for all updates to be installed. 
# Be patient, this will take a long time.

# When you see the following, the updates are complete:
localhost                  : ok=5    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0   
JD-SCCM-MECM               : ok=8    changed=5    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0 

7. Snapshot VMs

Take snapshots via the proxmox web UI or SSH into ludus and as root run the following

export RANGEID=JD # <= change to your ID
vms=("$RANGEID-SCCM-DC" "$RANGEID-SCCM-MECM" "$RANGEID-SCCM-MSSQL" "$RANGEID-SCCM-CLIENT")
COMMENT="Clean GOAD SCCM setup after ansible run"
# Loop over the array
for vm in "${vms[@]}"
do
  echo "[+] Create snapshot for $vm"
  id=$(qm list | grep $vm  | awk '{print $1}')
  echo "[+] VM id is : $id"
  qm snapshot "$id" 'snapshot-'$(date '+%Y-%m-%d--%H-%M') --vmstate 1 --description "$COMMENT"
done
