Similar to our Teaser, the theme for this edition was the Internet of $h!t, therefore a number of challenges were inspired by absurd IoT devices. A few tasks actually ran on real IoT devices…

Despite the large number of tasks (31, including multi-steps tasks) all challenges were solved at least once during the CTF!
