2017, CTF, DefCamp Finals

English [DCTF FINALS 2017] BACK ON THE EVENT

Leave a comment

Hello everyone,

Last year, we were on final for the Defcamp. We finished in the bottom of the ranking (thanks to… actually to the night before, which had been a bit rude ^^).
But this year, we decided to be better (even if we again tried a lot of bars). And it paid! We were constantly moving from place #5 to #6, and ten minutes before the end, one of us flagged a challenge, and secured the 5th place!

Even if it’s not the first time we get into the Top5, we were in front of famous teams, and it was a real challenge to deal with it. But, hey, fighting DCUA, P4, and others was really fun after all! 🙂

We would like to thanks the organizers of the CTF, and of the Defcamp for their awesome work, and to say them : “See you next year ;)”

Here are the ranks :

Hello buddies,

From Saturday 24th 10AM to Sunday 25th 7AM, there was the most known french conference: Nuit Du Hack. As every  year, it was an awesome conference, with a lot of conferences, friends, workshops, and beers 🙂

But, it’s not only conferences, it’s also challenges! And, here, at 0x90r00t, we love challenges (I bet you already knew it 🙂 )!
So, we did the public CTF and finished 7th, which is not bad!

This year, Wavestone also organized a mini CTF during the day, just for fun (and actually, it was really fun), and we finished 3rd!

Oh… But wait… I almost forgot! There was a spying challenge, and… oh… actually, we finished first! 😉

You’ll find some write ups below:

  • Spying challenge part 1 (FR only)
  • Spying challenge part 2 (FR only)
  • Spying challenge part 3 (FR only)
  • More soon

And here is the ranking (thanks to P_TE for the picture)!
