This guide explains the objectives of the OffSec Advanced Evasion Techniques and Breaching Defenses (OSEP) certification exam. Section 1 describes the requirements for the exam, Section 2 provides important information and suggestions, and Section 3 contains instructions for submitting your completed exam.
The OSEP certification exam simulates a live network in a private VPN, which contains a corporate network
You have 47 hours and 45 minutes to complete the exam.
This means that if your exam begins at 09:00 GMT, your exam will end at 08:45 GMT two days later.
Once the exam is finished, you will have another 24 hours to upload your documentation. Details on how to submit your files are provided below.
All OSEP exams are proctored.
Please make sure to read the proctoring tool learner manual and the proctoring FAQ at the following URL: https://help.offsec.com/hc/en-us/sections/360008126631-Proctored-Exams
The exam consists of one large network with multiple machines that must be compromised. As the exam network simulates a corporate network, you will have to first obtain a foothold and then perform additional internal attacks. There are multiple attack paths through the network that will result in the same level of compromise.
Some of the machines will require multiple exploitation steps, resulting first in low-level local access, and then in root or administrative privilege escalation. Other machines will be fully exploitable remotely.
While we cover a number of more advanced techniques in this course, foundational attack components are also part of the exam.
Specific instructions for your target network will be located in your Exam Control Panel, which will only become available to you once your exam begins.
You are required to write a report describing your exploitation process for each target.
Your report must document all of your attacks including all steps, commands issued, code written, and console output. Your documentation should be thorough enough that your attacks can be replicated step-by-step by a technically competent reader.
The documentation requirements are very strict and failure to provide sufficient documentation will result in reduced or zero points being awarded. Please note that once your exam report is submitted, your submission is final. If any screenshots or other information is missing, you will not be allowed to send them and we will not request them.
If you have not made any modifications to an exploit or tool, you should only provide the URL where the exploit or tools can be found. Do not include the full unmodified code, especially if it is several pages long.
If you have modified an exploit or written custom code, you should include:
- The modified exploit code
- The URL to the original exploit code (if applicable)
- The command used to generate any shellcode (if applicable)
- Highlighted changes you have made
- An explanation of why those changes were made
Your objective is to exploit the corporate network and compromise the designated critical asset while providing proof of exploitation.
Not all targets contain proof files, some may contain one or two proof files which you must retrieve, submit in your control panel, and include in a screenshot with your documentation. Failure to provide the appropriate proof files in a screenshot for a given level of access will result in zero points being awarded for the target.
Low privileged access proof is given in local.txt files, privileged access proof is given in proof.txt and the final proof is given in secret.txt.
The only accepted way to provide the contents of the proof files is in a remote interactive shell on the target machine with the
cat command from their original location.
Obtaining the contents of the proof files in any other way will result in zero points for the target machine. This means a web shell or RDP session is not sufficient.
The exam control panel contains a section available to submit your proof files. The contents of the local.txt, proof.txt, or secret.txt files obtained from your exam machines must be submitted in the control panel before your exam has ended.
When entering the proof, you must also enter the hostname it is located on.
Each local.txt, proof.txt and secret.txt found must be shown in a screenshot that includes the contents of the file, as well as the IP address of the target by using
ip addr. An example of this is shown below:
You cannot use commercial software such as Metasploit Pro, Cobalt Strike, Core Impact, or Burp Suite Pro. In addition, spoofing attacks against ARP, DNS, NBNS, or IP are not allowed as they can disrupt the exam environment. Also, AI chatbots such as ChatGPT, YouChat, and similar are not allowed.
Open-source, community, or custom software that performs automatic enumeration and/or exploitation like Metasploit Community, PowerShell Empire, Covenant, Bloodhound or SQLmap is allowed in the exam.
Please note that we will not comment on allowed or restricted tools, other than what is included inside this exam guide.
NOTE: While you may use Discord as a resource for searching for information during the exam, under no circumstances are you permitted to seek or receive assistance from others on the platform.
Downloading any applications or source code from the exam environment to your local machine is strictly forbidden. For more information, please refer to the https://www.offsec.com/legal-docs/

The exam control panel is available via a link provided in your exam email. Through the exam control panel you will be able to:
- Submit proof files
- Revert target machines
- View specific target objectives and point values
You have a limit of 50 reverts. This limit can be reset once during the exam. All of the machines will have been freshly reverted at the start of your exam, so you will not be required to revert the machines when you begin.
Note that machines are reverted in groups to ensure stability of the exam network. Please wait patiently for the machines to revert and only click the button once per attempt. Reverting a target machine will cause it to return to its original state, and any changes you have made to the machine will be lost.
- local.txt - This file is accessible to an unprivileged user account and can only be found on certain machines. The targets containing these files will allow a foothold as an unprivileged user.
- proof.txt - This file is only accessible to an administrative or root user and can be found under the /root/ directory or the Administrator Desktop. This file is present on most machines.
- secret.txt - This file is the proof that is found only on the final machine in the attack simulated penetration test.
- The order in which the exam machines are documented inside your exam report is the same order in which the exam machines will be graded and valued
- Points will be awarded for partial and complete administrative control of each target machine
- Each machine has a specific set of objectives that must be met in order to receive full points
- You must either obtain access to an objective described in your exam email or achieve a minimum score of 100 points to pass the exam
You will receive no points for a specific target for the following:
- Using a restricted tool
- Failure to provide the local.txt, proof.txt and secret.txt file contents in both the control panel and in a screenshot
Ideally, one of the following templates should be used for the penetration test report:
You may use your own template as long as the information is presented in a structured, professional manner and follows all other requirements outlined above.
This subsection of the exam guide explains what you should do in case you are unable to complete your exam due to severe external factors. Please make sure to read and understand it carefully.
The exam lab is a dedicated environment with no learners connected other than yourself. The total allotted time of 47 hours and 45 minutes does take into consideration the regular interruptions of everyday life.
- You are expected to take rest breaks, eat, drink, and sleep
- You are also expected to have a contingency plan in the event that there is an issue outside your control. (e.g. ensure you have access to a backup Internet connection, Kali Virtual Machine, power etc)
If you have a legitimate issue, please send an email with your OSID to "challenges AT offsec DOT com" immediately. Make sure to include all the necessary details and supporting information such as a letter from your power company, ISP, or any other relevant documentation.
If you lose significant lab time due to a technical issue that is OffSec's responsibility, please contact us. If the exam subnet is not immediately in use by another learner following your exam, we may be able to extend your lab time. If it is scheduled to be in use, we will provide you with a free exam retake attempt. We work very hard to ensure our environments are highly available and issues are rare.
If you encounter any connectivity problems with the VPN or target machines, inform us immediately, directly in the proctoring chat. Should you not be able to access the proctoring tool, please contact us via the live chat available at https://chat.offsec.com/ or via email to "help AT offsec DOT com".
Please note that we will not be able to assist with or give hints on any exam objectives, and we will only be available to help resolve technical problems during the exam.
