March 26-28, the 2021 edition of the Swedish High-School CTF championships, "Säkerhets-SM", took place. The competition aims to bring high school students (and others) some nice security challenges and expose them to the fantastic world of CTFs.

For more info and to participate: https://sakerhetssm.se/

I will host a stream where I will go through the challenges from Säkerhets-SM 2021, how to approach them and how to solve them. Note that the competition is (at least partially) in Swedish but this stream will be in English.

To try the challenges on your own, see: github.com/Kodsport/sakerhetssm-2021-solutions
