Participate

To participate in our Cybersecurity Days, you need to have an HPI account. If you don't have one but would like to participate anyways, we are happy to supply you with a guest account, which is not different to all the other accounts. Just drop us a message on our Discord then.
With your account, you can login to the platform. You will be asked to either enter your username/password combination or (for all HPI students) just click on "HPI OIDC" to authenticate with your HPI account.

VPN

Many challenges require you to have a working VPN connection to our internal challenge network. Therefore, you have to register with our VPN self-service portal. On login, please select OIDC, then just authenticate like you did with our challenge plattform.
Via the VPN self-service portal you can add yourself a Wireguard VPN-Endpoint. Please follow the on-screen instruction after creating a first device. If you need help setting up the VPN, feel free to reach out to us via our Discord (link on homepage).

When you are connected to the VPN, you should be able to solve the VPN Beginner challenge inside the ctf.
