CTF event organized by justCatTheFish team.

Introduction of justCatTheFish team: Hi! We are the best team from Poland and one of the top teams in the world (4th place in 2023).

Our team emerged from two other teams with origins from AGH UST and UWr universities in Poland. Currently, we have members from different places in Poland but we are not limiting ourselves to only polish members.

We managed to intercept description of some kind of a security module, but our intern does not know this language. Hopefully you know how to approach this problem.

We intercepted yet another security module, this time our intern fainted from just looking at the source code, but it's a piece of cake for a hacker like yourself, right?
