Malware Analyses Lab Setup: FlareVM and Remnux

Create an isolated environment in Virtual Machine using FlareVM and Remnux.

These home labs are placeholder scenarios while I document the full walkthroughs. The environments, objectives, and tooling reflect my real-world practice runs, and I'm actively expanding the playbooks with screenshots, scripts, and validation data.

Malware Analyses Lab Setup: FlareVM and Remnux

You will understand how to create an isolated virtual environment which is safe to analyse dangerous malware samples and learn to create a network to isolate VMs from host machine.

🧩 Lab Scenario

  1. A simple yet effective lab to analyse malware samples.

💻 Step 1 - Install Virtualization Software (Eg VirtualBox)

  1. Download virtual box setup depending on your OS:
    bash
     Windows hosts
 MacOS
 Linux Distributions
  2. Keep the setup settings as default(Recommended).
  3. Open the virtualization software.

💻 Step 2 - Install Remnux

Download the virtual box .ova file .And follow the instructions as mentioned.

💻 Step 3 - Install Windows 10 ISO.

  • Go to the Microsoft Website.

  • Download the Windows 10 Media Installation.

  • Run the installation and choose ISO to create a Windows 10 iso file.

  • Use that ISO file to create a Windows 10 VM.

💻 Step 4 - Install FlareVM

  • Go to this Github Repo and follow the instructions as mentioned.

  • After running .\install.psi, you may encounter installation getting stuck during some program installation such as vscode.Wait 10-20 mins and if it is still stuck right click on the powershell and it will skip it.

🚨 [IMPORTANT] Follow further steps carefully to make your environment isolated.

bash
- It is important to create an isolated environment to prevent malware getting leak to host machine.
- Go to File > Tools > Network Manager of VirtualBox.
- Create a new `Host-only Network` adapter.
- Below you will see two sections - `Adapter` and `DHCP Server`.
- Click on "Configure Adapter Manually" and set the value as :
bash
    IPv4 Address: 10.0.0.1
    IPv4 Network Mask: 255.255.255.0
    IPv6 Address: *leave as default*
    IPv6 Prefix Length: *leave as default*
  • Now go to DHCP server pane and check "Enable Server".
  • Set the value as -
bash
    Server Address: 10.0.0.2
    Server Mask: 255.255.255.0
    Lower Bound: 10.0.0.3
    Upper Bound: 10.0.0.4

  • Now go to settings of both FlareVM and RemNux and set network from NAT (or Bridged) to Host Only network adapter and select the new network adapter which you created.

  • Remember to take snapshots of each vm one more time with all these configurations set up.
