Very quick challenge this one, solved in one line shell script. Here’s the clue:

Cool CTF, finished top 10 so I’m happy with that. Again it began mid week for me but I got sick with a virus so had to stay home anyway. What better to do than to CTF until I feel better?

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.
