Getting started with CTF’s

Rookie Track

Jeff (@bl4krat) has worked in physical security for 25 years. He is a volunteer Air Cadet instructor. In his spare time, he plays with radio, photography, locks, guns, electronics and all things cyber. He was once described as a hoopy frood.


Capture The Flag challenges (CTF’s) are an excellent way to learn some cyber skills, and the good news is that there are loads of free ones online. This is the story about how one newbie started off with some of the less-frequently talked about CTF’s. I’ll provide a walkthrough for one or two example challenges, probably from either the UK Cyber Security Challenge PoD (play on demand) or the Sans Holiday Hack Challenge.
