PHASE 3: Creating the isolated lab network

[Illustration Placeholder: Simple network diagram—two VMs inside a shielded “Internal Network,” host and Internet blocked]

Instructions

1. For all lab VMs, set Adapter 1 to “Internal Network.”
2. Give this network a unique name (e.g., malware-lab-net). The name must match exactly for both VMs.
3. 
   
4. ⚠️ CRITICAL: Do not use “NAT,” “Bridged Adapter,” or any other network type for these VMs.
5. Only VMs on the same “Internal Network” name can communicate. This prevents malware from escaping your isolated environment.

Tips & Notes

1. Network isolation is the single most important safety step in this entire protocol.
2. “Internal Network” is case-sensitive. Double-check the network name for every VM.

✅ CHECKPOINT 3: Lab network isolation

1. All lab VMs are set to “Internal Network” with an identical name.
2. You understand and confirm that no other network adapters are enabled.

PHASE 4: Building the “Attacker” VM (Windows XP)

10. Install Python 2.6.6 and PyWin32 v212 (required for older Equation Group tools).
11. To transfer tools, create a read-only ISO and mount it as the virtual CD-ROM inside the VM.
12. Never use shared folders, USB, or drag-and-drop for file transfer.
13. Shut down the VM and take a snapshot named [1] Clean Install - Ready to Attack.

Tips & Notes

1. Disabling shared folders and clipboard is a critical defense against malware escaping the VM.
2. Snapshots allow instant recovery after each experiment.

✅ CHECKPOINT 4: Attacker VM lockdown

1. Adapter 1 is set to Internal Network only.
2. Shared folders, clipboard, and drag’n’drop are Disabled.
3. Audio controller is Disabled.
4. Clean snapshot has been taken and named.

9. Inside the VM, go to Control Panel > Windows Firewall > Turn off Windows Firewall.
10. Shut down the VM and take a snapshot named [1] Clean Install - Ready to be Attacked.

Tips & Notes

1. This VM must never be allowed to connect to the Internet.
2. Disabling Windows Firewall is for this lab only—never on a real, non-lab machine.

✅ CHECKPOINT 5: Victim VM lockdown

1. Adapter 1 is set to Internal Network only.
2. Shared folders, clipboard, and drag’n’drop are Disabled.
3. Firewall is Disabled.
4. Clean snapshot has been taken and named.

PHASE 6: Final lab verification

[Illustration Placeholder: Network diagram—two VMs successfully ping each other, host ping blocked with a red X]

Instructions

1. Start both the EQ-ATTACKER and VICTIM-WIN7 VMs.
2. In each VM, open the Command Prompt and run ipconfig to find the VM’s IP address.
3. From the Attacker VM, ping the Victim VM’s IP address.
4. This ping should succeed.
5. From your host computer’s command prompt, ping either VM’s IP address.
6. This ping must fail with an error like “Request timed out.” If not, fix your VM network settings before proceeding.
