Live and playable CTF Archives continue to come out of the vault including one that just happened! Enjoy the ability to continue playing the NahamCon 2025 CTF at your own pace. There are 30 challenges of varying levels. This CTF is great for all players, as it has several crazy easy flags all the way to John Hammond’s extreme web-focused challenge, “Talk Tuah”!

JHT’s CTFs are housed in a web-based lab environment with your own, dedicated copy of Kali and the challenge server. The only difference is that there’s no time limits and no scoreboard. Learn with no pressure and at a low price point.
Price = $20
Feel free to write walk-throughs and share them with fellow players on your own blogs, social media or in our Discord. If you do, be sure to let us know by tagging JHT!
What do I get?
All CTFs come with a web-based version Kali Linux for you to tackle the challenges. To make things even easier, ALL challenges are on server. No need to start a new machine for each and every challenge. It doesn’t get any easier than that to start learning.
CTFs are $20 and come with a ton of lab time. If you run out, you can always purchase more at an affordable price.
