# Scenario Infrastructure

We hope to capture the general structure of what is reported to have been seen being used by Blind Eagle.

The requirements described herein should be considered a bare minimum to execute the scenario. If you have the time and resources to remain true-to-form, you may elect to stand up multiple of each of these servers, non-contiguous IP space, etc. If you are not concerned with emulating Blind Eagle to this degree, this level of effort is not necessary. You could for instance, phish, serve payload, and act on objectives on a single server.

Below are the domains and infrastructure used to support the setup and execution of the Blind Eagle Emulation plan.

This emulation leveraged the following attacker infrastructure with configurations.

• This evaluation utilizes payloads that model malware previously used by Blind Eagle.
• These utilities include loaders, injectors, and implants.
• The Binaries.zip contains all executables in one zip file for easy download. The password is malware.
  • Implants are configured to connect back to static IP address 192.168.0.4. Build instructions for each payload can be found with source code in their respective directories.

RDP to your Windows Attack Platform

1. Open Windows Defender and toggle all of the knobs to the off position - this is so that Defender will not eat your malware

   

2. Open a PowerShell Prompt and download the Blind Eagle ATTACK Evaluations Library to your chosen directory on your Windows attack machine

   git clone https://github.com/center-for-threat-informed-defense/blackhat-2023-becoming-a-dark-knight-emulation

3. Open File Explorer and navigate to the repo directory Resources\Binaries\. Right click -> Extract Files on Binaries.zip and provide the password malware when prompted

SSH to the web server from either your machine or a separate PowerShell prompt on your Windows Attack Platform:

ssh ubuntu@192.168.0.5

1. Download the Blind Eagle ATTACK Evaluations Library to the /opt folder on your Linux Web Machine

   cd /opt/

   git clone https://github.com/center-for-threat-informed-defense/blackhat-2023-becoming-a-dark-knight-emulation

2. cd to /opt/blackhat-2023-becoming-a-dark-knight-emulation and use unzip -P malware Resources/Binaries/Binaries.zip to extract payloads

   cd /opt/blackhat-2023-becoming-a-dark-knight-emulation

   unzip -P malware Resources/Binaries/Binaries.zip

3. Create a the following directories to host payloads from the attack users home directory:

   mkdir -p ~/web/{rump,dll,notificaciones/contribuyentes/factura-228447578537}

4. Use the Shell commands below to populate the binaries in the expected directories for the scenario:

   cp Resources/Binaries/asy.txt ~/web

   cp Resources/Binaries/new_rump_vb.net.txt ~/web/dll

   cp Resources/Binaries/Rump.xls ~/web/rump

   cp Resources/Binaries/factura-228447578537.pdf.uue ~/web

   cp Resources/Binaries/index.html ~/web/notificaciones/contribuyentes/factura-228447578537

5. SCP the bancomurcielago website built using Django CMS to the victim Web server ❗ this will be used in a later configuration step

   scp /opt/blackhat-2023-becoming-a-dark-knight-emulation/Resources/Binaries/django-cms-quickstart.zip ubuntu@10.1.0.4:/opt

4 targets, all domain joined to the bancomurcielago domain:

Note: in the scenario, DNS records were manually created to emulate network activity from suspect domains If you wish to create DNS records the following will be useful for a complete emulation:

1. Create the user accounts as used in the scenario:

   username	groups
   demo_admin	Domain Users
   devadmin	EWS Admins, Domain Admins, Domain Users

RDP to the workstation from either your computer or the Windows Attack Machine:

1. Open Windows Defender, toggle all nobs to the off position - this is so that the malware can execute properly to completion If it is is useful to your organization to test defenses against this adversary you may choose to do this differently, however some tradecraft is likely to be blocked by modern EDR solutions (we hope)

   

SSH to mail from either your computer or the Windows Attack Machine:

ssh ubuntu@10.1.0.11

1. Setup Exchange Server to host OWA and EAC.
2. Create the "EWS Admins" group, adding devadmin

1. Remove any prior Docker and Docker-Compose installations:

   for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done

2. Install prerequisite packages:

   sudo apt-get update
   sudo apt-get install ca-certificates curl gnupg

3. Set up Docker APT repo:

   # add gpg key
   sudo install -m 0755 -d /etc/apt/keyrings
   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
   sudo chmod a+r /etc/apt/keyrings/docker.gpg
   
   # set up repo
   echo \
   "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
   "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
   sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
   
   # apt update
   sudo apt update

4. Install Docker and Docker Compose:

   sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin unzip

5. unzip website built with Django CMS in /opt/ on bancomurcielago-linux-srv3

   unzip /opt/django-cms-quickstart.zip

6. Run the website with Docker:

   cd /opt/django-cms-quickstart
   sudo docker compose up -d

The bancomurcielago website should now be hosted on HTTP port 8000

The Binaries.zip contains all executables in one zip file for easy download. The password is malware. ❗ binaries in this folder will only work with the infrastructure configuration described in this document as some payloads need to be built with specific URLs hard coded.
