n00bs CTF (Capture the Flag) Labs is a web application presented by Infosec Institute. It has 15 mini Capture the Flag challenges intended for beginners and newbies in the information security field or for any average infosec enthusiasts who haven’t attended hacker conventions yet.

So what is a CTF? In hacker conventions, CTF or Capture the Flag is a game event which has challenges that vary from exploitation, CrackMes, crypto, forensic, web security, logical games, wireless security, and many more.

If you just want to have fun and dive in then these challenges are for you.

Each level can be hopped in the navigation bar of the web application where different kinds of challenges are in place which include basic static source code analysis for a page, file analysis, steganography, pcap (packet capture) analysis, and other basic forensics challenges.

Here is a screenshot of the Level 8 page:

As what you can see from the image above, you need to download app.exe and then decompile it.

This exercise is meant as an educational experience – about learning and developing your skills for the greater long term good. But we do want this to be fun, too! For that reason, we are offering cash bounties totaling $1200 for people successfully winning up to three flags and posting helpful write-ups online. (Details provided on the CTF site, accessed through the form below.)

In the meantime, there are many articles you can find in the Resources archives that offer up useful information which will help you advance through each level.
