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.

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.

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.

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 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.
