Nuit du Hack Quals 2015 - Bpythonastic - Forensic Challenge

CTFing at Easter time was super challenging. Endless family commitments, using my iPhone to browse challenges while at the dinner table and thinking through how to attack them when I can finally get to a PC. Fortunately NDH seemed to go for long enough for me to at least try a few of the challenges, which I did!

UIUCTF 2015 - hype - Web Challenge

Didn’t have time to do UIUCTF this year since it ran concurrently with NDH but I did this challenge to help a team member out who was doing it and it only took 15 minutes. It was a fun challenge called hype, worth 100 points.

Backdoor CTF 2015 - qr - Challenge Response

Due to the rescheduling of Backdoor 2015 (due to cricket, blegh) I only got about 2 hours to play it. It seemed like a good variety of challenges and I think I would have got 7 or 8 done had it not been on a weekday when I had a tonne of other commitments. Anyway I got started with this challenge, it was easy but fun but only worth 70 points and In my opinion there were a lot of easier challenges worth more points. Still I got stuck down the rabbit hole anyway.

0ops CTF Qualifiers 2015 - Vezel - Mobile Challenge

I haven’t ever done a mobile challenge before so I thought I’d give this a try as it was one of the earliest challenges made available on the 0ctf site when it began. The clue was only this:

Securinets CTF Quals 2015 - aucun_choix Reversing Challenge

What a strange CTF this one was. Judging by all the comments on CTFtime a lot of people couldn’t get past the registration page. I myself registered ok, it was in French but Google translate got the message across. When I began the CTF I immediately noticed that this was a challenge for beginners. That’s great I do need to brush up on my basic skills.
