CTF? what?
Capture the Flag (CTF) is a special kind of information security competitions.
Jeopardy-style CTFs has a couple of questions (tasks) in range of categories. For example, Web, Forensic, Crypto, Binary or something else. Team can gain some points for every solved task. More points for more complicated tasks usually.
the team
I started capturing flags in October 2020 with some friends from the University.
We created a team to compete, CangureTheFlat, but don't ask how we came up with this name.
Surprisingly enough we did well:
🦘 33th Italian team in 2020
🦘 41th Italian team in 2021
🦘 20th Italian team in 2022
We now try to participate in some events, but every member of the team has its own work/study business, so we won't be as active as we want to.
write-ups
CTF challenges are often about something you never heard about, and you constantly need to make researches. I think that one of the best way to learn and make others learn is to keep in mind how you solved previous challenges, so I decided to keep track of them with some blog posts. Hope you find them useful too.
