The Lockdown from the Fault Injection category, which was not the most ‘valuable’ (in points) challenge was not solved by anyone. The ‘easiest’ challenge was Ransom from Reverse Engineering category, solved by 76 teams or individuals. The most ‘expensive’ challenge, the Climate Controller Catastrophe, was solved by 13 teams. The ‘easiest’ hardware challenge from the Side Channel Analysis category, known as ‘It’s a kind of magic’ was solved only by 14 teams. 96 individuals or teams solved at least one challenge in the main phase, out of ~500 people who passed the qualifications.
