Hack.Lu - Creative Cheating 150pt Crypto Challenge

A mid week CTF when I have final exams! Argh! Still I play because I’m an idiot. Fun CTF, hard to read the font they chose but still fun. This was a classical RSA challenge with almost no difficult points but I’ll write up anyway.

Hackover15 - goto - 150pt Reverse Engineering Challenge

I didn’t get time to play Hackover 15 as much as I wanted. It looked like a really fun competition but unfortunately it overlapped with Hitcon 2015. However I woke up super early (6am Saturday - eek!) to get a few hours in on Hackover before Hitcon started.

HITCON 2015: PuzzleNG - 250pt Forensics Challenge

I don’t mind admitting that Hitcon was HARD. Possibly some of the hardest challenges I’ve faced CTFing so far. Or maybe I was just rusty. Anyway here’s one challenge I found particularly rewarding from Hitcon 2015.

D-CTF 2015: r100 and r200 Reverse Engineering Challenges

I didn’t have any time to play D-CTF this year because im out of the country traveling. I did spend one evening solving these two challenges though because I thought of an interesting idea I could apply to both challenges simultaneously.

Trend Micro CTF - vonn - Analysis-Defensive (100) Challenge

Trend Micro CTF was this weekend. This is the first one of these Trend Micro CTF I’ve done and I was expecting it to be really well run and fun.
