The VulnHub release listing provides these specifications and instructs users to map the lab hostname to the VM’s IP address.

Level 1.2 (#3) and Level 3 refer to the same challenge. If you need Kioptrix_Level_1.rar, that is the first challenge in the series, not this download.

Prepare Your Practice Environment

Use a dedicated lab containing the Kioptrix VM and a separate testing VM, such as Kali Linux.

Before booting Kioptrix:

  • Extract the archive with a utility that supports RAR.
  • Keep the extracted configuration and disk files together.
  • Check that your virtualization application supports the supplied VM format.
  • Connect both VMs to the same isolated virtual network.
  • Remove unnecessary network adapters that could connect the lab to other networks.

Kioptrix is intentionally vulnerable. Avoid bridged networking, public exposure, and personal data inside the target VM. Review VulnHub’s network safety guidance before running it.

Set Up Kioptrix Level 3

1. Extract and Open the VM

Extract KVM3.rar into its own folder. In compatible VMware software, use the option to open an existing virtual machine and select the extracted .vmx file.

Keep an untouched copy of the extracted folder in case you need to start again.

2. Check the Virtual Network

Place Kioptrix and Kali on the same isolated network.

Host-only networking permits communication with the host as well as connected VMs. An internal VM network can provide stronger separation from the host, but you must arrange addressing appropriately.

Check DHCP availability rather than assuming every isolated network assigns addresses automatically.

3. Find the Target’s IP Address

Start both machines and identify the address assigned to Kioptrix on your lab network. Depending on your virtualization application, its DHCP lease information may help.

Use the address from your own environment. Addresses shown in tutorials are examples and may not match your setup.

4. Add the Lab Hostname

Do not skip this step. The release instructions call for a hosts-file entry so the challenge’s web application can use kioptrix3.com.

Make the change on the machine where you will run your browser and testing tools—usually your Kali VM.

On Kali Linux, open the hosts file:

sudo nano /etc/hosts

Add a line using the Kioptrix VM’s actual IP address. For example, only if your target is 192.168.56.103, add:

192.168.56.103 kioptrix3.com

Keep existing entries intact, save the file, and close the editor.

If you browse from Windows instead, the corresponding file is:

C:\Windows\System32\drivers\etc\hosts

Editing it requires administrator privileges.

5. Open the Lab Website

In the browser on the machine with the hosts entry, enter http://kioptrix3.com.

This hostname should resolve to your private lab VM. It is a local lab address in this setup, not a public website to visit or test.

If the target’s IP address changes later, update the hosts entry before continuing.

6. Preserve Your Starting Point

Once the lab works, take a snapshot if your virtualization application supports it. Record the target’s IP address and network settings alongside your notes.

Troubleshooting

ProblemFirst checks
The archive will not extractConfirm the download finished and your extraction utility supports RAR.
The VM cannot locate its diskCheck that all archive files were extracted and remain together.
Kioptrix has no usable IP addressCheck the connected virtual adapter and DHCP service on the lab network.
Kali cannot reach the targetConfirm both VMs are on the same isolated network with compatible addressing.
The IP address works but the hostname does notCheck the hosts file on the machine actually running your browser.
The website looks incomplete or links failConfirm kioptrix3.com maps to the current target IP and browse using that hostname.
The hostname opens an unexpected public siteStop and fix local name resolution before continuing.
A previously working setup stops respondingCheck whether DHCP assigned a new address and update the hosts entry if needed.

For hostname problems on Kali, you can inspect the system’s resolution result with:

getent hosts kioptrix3.com

The returned address should match your Kioptrix VM. A correct result confirms name resolution; it does not, by itself, prove the target’s web server is responding.

Continue Your Practice

Once the website loads, explore the lab before opening a complete solution. Keep notes on what you observe and the questions you want to investigate.

Frequently Asked Questions

Why did an old KVM3.rar link bring me here?

Older tutorials may link to /dlvm/KVM3.rar. This page helps you locate the external download and prepare the lab, including the hostname configuration.

Is this a walkthrough?

No. This guide covers downloading and setting up the VM without revealing the challenge’s exploitation steps or solution.

Does this website host the archive?

No. The download button points to the mirror listed by VulnHub. Download availability depends on that external host.

Can I access the lab using only its IP address?

Some content may respond, but the release instructions require the hostname mapping for the web application to display properly. Configure the hosts entry and use http://kioptrix3.com inside your lab.

Do I need to change public DNS settings?

No. The hosts-file entry is a local setting on your testing machine. You do not need to register a domain or change your router’s public DNS settings.

Get KVM3.rar from the VulnHub mirror and keep this guide open while you configure the lab.
