REMnux is a specialized Linux distribution designed for malware analysis, available as a preconfigured virtual appliance. This guide provides clear, step-by-step instructions to help you set it up on VMware. Whether you’re new to virtualization or experienced, you’ll learn how to download, verify, and configure REMnux to ensure smooth operation. Let’s get started!
Download the REMnux Virtual Appliance
Go to the REMnux Website: https://remnux.org/
Click on “Download the REMnux Virtual Appliance”.
The REMnux virtual appliance approximately 5 GB. It comes as an industry-standard OVA file, which you can import into your virtualization software. It’s based on Ubuntu 20.04 (Focal).
Decide which OVA file to download. Download your preferred OVA file:
Box (Primary) Best Choice If: You prefer downloading from the primary source.
You have a reliable and fast internet connection.
SourceForge (Mirror) If: The Box link is slow or not working for you.
You prefer downloading without creating an account.
Try Box first, as it’s the primary source. If you face issues with the download speed or account requirements, use the SourceForge mirror instead.
Both links will give you the same file, so there’s no difference in the OVA you’ll get.
Important Note: Some browsers (e.g., Brave) change the extension of the OVA file after downloading it, possibly giving it the incorrect .ovf extension. If that happens, rename the file so it has the .ova extension before proceeding.
Verify the Download (Optional):
If you want to confirm the file’s integrity, compare its hash (checksum) with the one provided on the REMnux website.
Use a tool like sha256sum (Linux) or CertUtil (Windows) to calculate the hash of the file.
Opened Command Prompt
Navigate to the folder where the REMnux .ova file is located.
cd C:\Users\YourUsername\DownloadsVerify the REMnux OVA file
CertUtil -hashfile remnux-v7-focal.ova SHA256The hash that was calculated:
796a259733604b10c69a7b060e64eeccd459e33f327f8d9faf9fd22a1ca19645
matches the hash shown in the documentation.
Import REMnux into VMware
Ensure Your VMware Workstation is Updated:
Before proceeding, update your VMware Workstation to the latest version to avoid compatibility issues.
To check for updates: Open VMware > Help > Software Updates.
Open VMware Workstation
Click on “File” → “Open” or “Open a Virtual Machine”.
Browse to the location where you downloaded the REMnux .ova file and select it.
Enter a meaningful name for your virtual machine.
Click Browse to select a folder where the virtual machine files will be stored.
Make sure the drive has enough free space (at least 40 GB).
Click “Import” to start the import process.
This might take a few minutes as VMware unpacks the virtual appliance.
Allocate Resources: Once the virtual machine is imported, allocate sufficient resources:
RAM: Assign at least 4 GB (8 GB is better if you have enough RAM).
CPU Cores: Assign at least 2 cores for smooth performance.
To adjust these:
Right-click the imported REMnux VM > Select Settings > Adjust the RAM and Processors under the “Hardware” section.
Once you start your REMnux virtual machine, it will automatically log you into the REMnux environment.
There is no logon screen for accessing the REMnux environment, because analysts generally use REMnux on a system to which physical access is already restricted.
Configure VMware Resources
Gain root access
sudo -sOpen the configuration file /etc/gdm3/custom.conf using a text editor
nano /etc/gdm3/custom.confLook for this line in the file: #WaylandEnable=false
Remove the # at the beginning
Save and Exit
Then reboot your virtual machine
rebootWhen you need to elevate your privileges or access the REMnux virtual appliance remotely, note the follow default credentials:
Username: remnux Password: malwareUpdate REMnux Tools
remnux updateFinal Notes
With REMnux successfully installed, you’re now ready to begin malware analysis. This powerful distribution equips you with the tools to investigate malicious files, analyze network activity, and reverse-engineer suspicious binaries.
Remember: Malware analysis is not just about identifying threats; it’s about understanding attacker techniques, tools, and behaviors, enabling you to defend systems effectively in the ever-changing landscape of cybersecurity.
