DaVinciCTF 2025 🥇🔥🖼️🧙

Infinite thanks to my team! We did perfect togethers 💖
The chad list:

• Drahoxx, our Hardware and chip whisperer 🗣️💽📟
• K.L.M, our Forensic legend (and nerfed Web3 king) 🕵️🔥
• Théo, QuantumDaddy, our Crypto Alan Turing 🔐⚡
  Many will say I was boosted for this CTF and I won't disagree 😅 I did my part and I'm very proud. But my team was just out of this world. 3 GCC Legends always rising to an higher prime version of themselves. I had a blast and enjoyed to the fullest the time spent with them and learned a lot.

Performance 🏆🥇

First win ! 🎉🥳 And won by a wide margin 🚀🤩
Of course this win is mostly deserved to my team than myself 😅 I didn't do bad per say, but there is such an improvement to be made here. I could have cleared the OSINT (it could be easily done and I really did shit work but we'll come back to it later) and I could have done some better work for the Reverse and Forensic. Forensic is pure skill issue and I need wayyyy more training but for the Reverse I just didn't listened to myself. I knew dnsSpy would have obliterated the challenge but I was absolutely sure and was too lazy to download the required tool. Two BIG mistakes that separate a good CTF player from a bad one in my opinion. The fear or laziness of not trying.
As always, I need to work more 🔨👨‍🔧 But this time I enjoy the win and party 🥳
Fun note: clutching an OSINT challenge 30 seconds before the end is so good 😎🤙

Rank: 🥇 with 10639 points 🤯🎉🚀🔥

How to improve 📝

Steganography

• Ok maybe I need to push my knowledges further in file analysis but steganography... Maybe not today...

Reverse

• I think I quite like Game Hacking. Maybe I'm influenced by my gamedev background but I really like the concepts and challenges I'm facing.
• We need to work on Game Hacking challenges in Hack The Box so maybe it's a good time to start diving in the subject 👀

OSINT

• Need to work on more traditional challenges => CVE, Malware, Process, IoCs, ...
• Do more complex challenges for RAM dumps and Disk analysis. Especially when challenges need to dive into processes, their files, how they work, how to retrieve intel from them, ...

OSINT

• HAVE YOU HEARD OF MASTODON GRANDPA ?!?! 👴
• I wrote back at Breizh CTF 2024 to work on my SOCINT Methodology. And well looks like I'm getting worse with time. I completely F-ed up and I need to start relearning SOCINT from start at this point. If I can't find a simple Mastodon account, let's not talk about Matrix, VK, Telegram, ...
• I need to reconnect and grind ⛏️
