CTF Practice

Getting Started

Probably the best resource to get started. LiveOverflow runs a YouTube channel that goes through different hacking challenges and explains things from the ground up for people with little to no hacking experience. Heard about a big hack in the news? LiveOverflow also takes those and explains how those attacks work so that you can understand it as well.

The ‘CTF Field Guide’ and CTF WTF
“What’s a CTF? How do I start?” These site can give a beginner some quick pointers on how you might start to learn hacking and cyber security topics.

CTF Writeups
Found an old security competition/CTF and want to know how the problems were solved? This is a huge community-driven collection of write ups to CTF competition challenges for the past several years. Just don’t rely on them too much - the more you try the problems yourself and the less you rely on the writeups, the better you’ll get!

CTFTime: CTF Competitions This website keeps track of past, ongoing, and future CTF competitions and the teams that compete in them. The majority of these competitions may not be beginner-friendly, but many teams take the time to make write-ups of problems, which may be more useful for someone trying to learn how to think about these problems.

Security Creators A randomized list of security video creators/streamers, information about the type of content, and where/when to watch.
