The first step in participating in any Hack The Box CTF is to register on our CTF Platform. This is a separate platform from the main website, and as such, requires a completely separate account.


Click the button below to view the CTF Platform!


Registering an Account

If you've never created an account on the CTF Platform, you'll need to do so. Luckily, the process is quick and easy! Click on the Register button on the landing page to pull up the registration form.

Fill out the form using a valid email, as this is where you will receive communications regarding the CTF, including information about post-CTF prizes. Once done, submit the form using the Register button, and you will be taken to the platform.


Joining a Team

You need to be a part of a Team to participate in a CTF, so you'll either need to join one or create your own. To join a Team, click the Join an Existing Team button and start typing the team's name. A dropdown menu will appear, and you can select the team you wish to join from that list.

After clicking the Join Team button, your join request will be sent to the Team Captain. They will then have the option to either accept or deny the request. In the meantime, the Team will show as Pending for you.

Once your request has been accepted, the status will change from pending to Member.


Setting a Team as Active

You'll need to set the Team you want to play for as your Active Team to participate in CTFs as a member of that Team. You can be a member of multiple Teams at once, but only one can be active at any given time.

To mark a Team as Active, click the arrow on the right side of the Team on the Teams Page, and press the Make Active button under the Team Actions tab.

The process is the same if you are a member of multiple Teams. Just select the one you want to make active, and follow the same process outlined above.


Creating a Team

Instead of joining an existing Team, you can choose to create your own! You can be the Captain and sail your hacking crew through the cyber-seas. Click on the Create a Team button.

Fill out the Team Creation Form with the appropriate information. The Team Discord Link field is not mandatory, but if you choose to fill it in, a Join Team Discord button will be available for your Team Members under the Team Actions panel.

Once you've filled out all the information, click the Create Team button to finish creating your team.


Managing Your Team

Accepting a Join Request

To add people to your Team, have them send a join request using the process detailed earlier in this article. Once they have done so, you'll have the ability to accept the join request.

To do so, navigate to the Teams Page and click the arrow to the right of your Team to open up the Team Menu. Navigate to the Members tab, and approve the join request by pressing the green checkmark.

Kicking a Member

As Team Captain, you have the ability to remove members from your team. Navigate to the Teams Page and open up your Team Menu. Under the Members tab, click the ellipsis next to the member's name, and then select Kick.

Transfering the Captain Role

You have the option to make a different member of Team the Team Captain. Please note, there can only be one Team Captain at a time, and transferring this role to another member will relinquish your control over the Team.

The process is the same as outlined above. Navigate to the Members tab in your Team Menu, click the ellipsis next to the member you wish to make Captain, and then click on the Make Captain button.


Joining a CTF as a Team

To play in a CTF, your Team Captain will have to make sure they have the team marked as Active. Then, they can navigate to the CTF Page and click Join CTF on the desired CTF.

If the CTF is password restricted, you'll be prompted to enter it here. Check the checkbox and then click Join. Please note, different CTFs may have different eligibility requirements to join, so be sure to read any information or updates publicized by Hack The Box for clarification.

Once the Captain has joined the CTF, all members who have the Team marked as active will be able to participate.
