Juniors CTF 2016 - Joy500 Oldschool NES Rom Write Up Markdown version

Published on Sunday, 27 November 2016 in Security

I played the Juniors CTF 2016 this weekend with some friends of mine and it was quite fun! Since we missed the registration deadline, I sneakily joined the Securimag team and played with them.

Oldschool challenge

One of the challenges was a modified NES ROM of Castlevania II - Simon's Quest. The challenge was not really hard after all but @xarkes and I thought that it was refreshing to play with a NES ROM for once :)

D-CTF Qualifiers 2016 - Web300 like a dipsh*t Markdown version

Published on Tuesday, 27 September 2016 in Security

First of all, wow it's been a while and a lot of things happened since last time I wrote something on my little spot of the Internet...

Last weekend I played the D-CTF Qualifiers 2016 with some friends of mine (@xarkes, jfrankowski and a new friend of mine). I was told that it is not a good CTF due to multiple problems in previous version with the challenges, where for instance some exploit challenge would not be solvable at all. And apparently it was the same this year (see the comments) and it was frustrating at some point...

However, it didn't stop us from having quite a blast. One in particular, the Super Secure Company LLC web challenge, worth 300 points. We used our best tool in French history, called puputerie, or how to gain 300 points like a dipsh*t!

If you're interested, keep reading and I hope you'll forgive me.

Quals NdH 2015 Clark Kent - re150 Markdown version

Published on Monday, 06 April 2015 in Security, Reverse Engineering

Last week-end I participated to the qualifications of NdH with HackGyver (scoreboard). We gathered at the hackerspace's local with futex, kiwhacks and pastrep (a new member met at the SecuRT 2015). We finished 32 over more than 200 teams that validated at least one challenge. It is not that bad, knowing that some of our key comrades where not available this Saturday.

Clark Kent Reboot

I had to do some stuff that I never did before and it was really fun. That is why I wanted to do the write-up of the Clark Kent reverse engineering challenge.
