There was one unintended bug in ice-and-fire service — just send NaN as one of the coordinates.

We will be really glad if you fill this feedback form: https://forms.gle/RfT125wrv12UWuPt9

Feel free to bring down your wrath here.

We will write a blogpost with all the things we've learned during this game not to repeat these mistakes next time.
You’ll have ~30 minutes to download everything from the boxes. After that, they’ll stopped and permanently removed.
The last information for today and we are free. We organize our CTFs and trainings on a regular basis. Though our infrastructure is cost-optimized, it is not 0. So we are open for donations if you want to support us. Vulnbox costs ~3$ per team.
