The OffSec Cyber Range Labs

The OffSec Cyber Range is a simulated network infrastructure that allows learners to sharpen their skills and demonstrate technical competence. It is integrated in the Learn Enterprise subscription which is accessible in the OffSec Learning Library. The environment provides learners with the ability to work with a variety of machines and networks to develop their skills in cyber security. It includes several chains of machines that are initially dedicated to each learner which are set to be powered up on demand.

The Labs machines include a mix of Windows and Linux operating systems, allowing for a comprehensive learning experience across multiple platforms. It also includes multiple networks, providing students with the opportunity to work with different network configurations. Additionally, there are multiple Active Directory chains, allowing students to gain hands-on experience with this commonly used tool in the IT industry.

Furthermore, the Labs includes a new attack type (XDay). This allows learners to gain experience in defending against new and emerging threats, preparing them for the ever-evolving landscape of cyber security.

Accessing OffSec Cyber Range in the Learning Library

To access OffSec Cyber Range, please go to the Labs section on the Library tab of your Learning Library account.

Connecting to the Labs

Your connection to the lab is to be done with Kali Linux using OpenVPN. We are unable to provide any VPN connectivity support if you choose to use another setup. It is also highly recommended that you download and use the Kali VMware image for the most streamlined experience. For more information, please visit here.

At the moment, universal VPN does not support OffSec Cyber Range. You will need to download the "OffSec Cyber Range VPN Connection File" to your Kali Linux machine from the "VPN" tab of your OffSec Learning Library control panel on the OffSec Cyber Range page. Use openvpn to initiate the VPN connection to the labs.

Once downloaded you will find an ovpn file that you will use to connect to the VPN.

Accessing mission objectives

When starting a lab machine, you will gain access to documentation that outlines your objectives.
If you need a second look at your objectives while working on the machine, simply click on the IP address in the machine list.

OffSec Cyber Range Dashboard

On your dashboard, you can:

• Search by lab machine name on the search bar.
• Filter by Operating system, difficulty and type
• Sort by machine name, points, difficulty, last action or by progress.
• Hover over the machine name to see the details of the machine such as: the machine name, the author of the machine, the release date of the machine and information if it includes a walkthrough.
• Start a machine.
• Revert a machine.
• Submit a flag.
• Provide feedback.
• Take notes.
• Access mission objectives.
• Rate a machine.

Flags submission

Flag values are dynamically generated when you start a machine and they are destroyed when the machine is stopped. That means that you should submit their values while the machine is still running. While we recognize that learners come with different experiences and this affects the time to exploit a machine, we also expect that to get the flag values any learner will need a minimum of 15 minutes working on a machine.

Rate and submit a feedback on a machine

To rate a machine or share your feedback, simply click on the 'Rate difficulty' and 'Feedback' buttons located in the Menu.
