European Cyber Week 2023 🇪🇺

Well well well... Third time's a charm 👀🤷
I went from qualified to not qualified to now qualified again.
So yeah 🥳⭐ I'll have my once in a lifetime chance.
I haven't trained sadly but I'll do my best as always

Performance 🏆

I worked hard the first and last week (I caught a huge cold on week 2 🥶💀). By solving almost all Easy challenges and one extra medium I nearly managed to get qualified but sadly I'm one off.

Rank: 55th with 775 points
with 10 challenges solved 🥳

How to improve 📝

Reverse

• OMG how did I not know how to extract an array from binary 💀AAAAAAAAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!! I could have been 47th I could just do the easiest part of a chall. OMG OMG OMG 🧂 🧂 🧂
• 👆 So with a calm mind I can say I should definitely work more on my interactive reverse abilities and should definitely start using more tool. I tried BinaryNinja during this CTF but should have tried Ghidra (There are some SICK commands 😍).

Crypto

• Work more on easy crypto challenges that are "wrong implementation"-like. There are some small details that I still miss (thinking about BMPaaS)

General

• Mindset was ok-ish. First week was a great start with a nice lead in 8th but my moral was slightly eaten bit by bit afterwards. Watch out for decreasing points, it really added a layer of unnecessary stress. A constant fear of never having enough points and seeing eroding progress. Last week had a nice comeback and good grind mindset.
• Tinker a bit more, Jigsaw2 (4/4) was more doable than thought.

Solves
