Cobalt Strike Ansible Deployment Guide

Environmental Prerequisite Setup

• Ensure that you have python3 installed, or that that the value returned from python --version returns a version greater or equal to 3.1.

• In order to work as expected, it is highly encouraged to take advantage of Python's virtualized environments, as the default installation namespace is global.

  python -m pip install virtualenv
  python -m virtualenv -p python3 Ansible_Virtual_Environment
  source Ansible_Virtual_Environment/bin/activate
  
  # Install modules local to this active virtualized environment
  (Ansible_Virtual_Environent)$: pip install ansible dnspython
  (Ansible_Virtual_Environent)$: ansible-galaxy collection install community.general
  

Playbook Prerequisite Setup

• Ansible operates primarily over SSH, and will require passwordless SSH keys added to any and all Linux hosts in question (teamserver and teamshare).

  • To generate a new SSH key locally:

    # Just hit enter for any prompts that occur.
    # This will allow create with no password.
    
    ssh-keygen -t rsa
    

• Start the relevant SSH server on the remote host(s):

  # On the remote server(s)
  service openssh start
  

• Add your newly generated SSH public key on the remote server(s):

  # From your current client host. E.g. your "attack" virtual machine.
  ssh-copy-id -i ~/.ssh/id_rsa root@remote_host
  

• Create an entry in your SSH configuration file, to have a reference to our endpoint(s), commonly residing in ~/.ssh/config:

  # Example configuration
  Host teamserver
      HostName 10.1.1.2
      User root
      IdentityFile ~/.ssh/id_rsa
  
  Host teamshare
      HostName 10.1.1.3
      User root
      IdentityFile ~/.ssh/id_rsa
  

• cd into the Ansible directory, and edit the variables contained in the playbook.yml file:

  # Teamserver variables 
  cs_license: ""
  provided_domain: ""
  provided_password: ""
  namecheap_user: ""
  namecheapapi_key: ""
  
  # Teamshare variables
  share_user: ""
  share_pass: ""
  

• You must replace the NULL'd out cobaltstrike.zip file, located in Ansible/roles/teamservers/files/cobalt_strike

Playbook Role Definitions and Features

Teamservers

- Provisions the `teamserver` as dicated in the `Ansible` inventory file
    - Installs pre-requisite software
    - Transfers `Cobalt Strike` profile (change as you see fit)
    - Populates initial `DNS` records within `Namecheap`
        - Awaits output on a thirty-second interval to determine if they have populated
        - Populates `DMARC` and `DKIM` records after successful propagation
    - Configures the `LetsEncrypt` `SSL` certificates for `@` and `www` primary/subdomain(s)
    - Configures the mailserver components (including users and passwords)

Teamshares

- Creates a "teamshare" with subdirectories for organization of common operational efforts
    - Allows creation of a primary account, under which, the user's home is the shared directory root

Playbook Execution

• From within the Ansible directory, run the following command:

  ansible-playbook -i inventory.yml playbook.yml
