VPN , VMs and Cloud Hosting 18.05.2022 20:00

Dear saarCTF participants,

with less than 2 days to go, we release VPN configurations and VM images on our website. Teams can now setup router VM and testbox VM. Please contact us per mail or IRC if things break.

Check vpn.ctf.saarland to see if your setup is functional.

If you want us to host the box for you, you do not need to prepare any VM - just distribute the cloud VPN configuration with your mates.

saarCTF 2022 announced! 21.03.2022 19:02

Our third iteration, saarCTF 2022 will take place on Friday, 20.05.2022, 14:00 UTC and last for 8 hours, plus one hour preparation time where network is closed. The competition is open to everybody.

We invite you to a classical attack-defense competition. This year, we offer you to host your vulnbox VM in the cloud for you, making things much easier to set up! Of course we will still provide Virtualbox images as a usual alternative.

The registration is now available, and will stay open until a few hours before the competition starts.
