Application Fuzzing Can Be Fun

One of the things my mother always said I was good at was breaking things. Apparently, as a young Evangelist, I chose to be an agent of entropy. I guess I always have been a huge fan of how things are continually breaking down and according to my mother at least, I did a lot to help them along the way. My mother just loves to tell stories about me taking things apart (clocks, radios, tv sets, lamps, my sister….) but I will save you from those, unless you choose to have coffee with my mother some day… 🙂

Today though, breaking software applications and studying how they fail has become a huge part of my work. I study how they fail, what causes the underlying issues, how those bad decisions could be exploited and what makes applications, devices and other things, tick. I am truly a student and professor of entropy.

You too can participate in these exercises. Tons of new tools are available to fuzz a variety of things, or you could choose to write your own fuzzers (this was a very worthwhile thing for me and led me to create “Defensive Fuzzing” which is the core of the HornetPoint defensive tools). (Patent Pending)

Here is a quick list of some books, papers and tools that you might want to explore if you are interested in playing with and learning from these techniques:

Fuzz testing – Wikipedia, the free encyclopedia

Ethical Hacking and Penetration Testing: Fuzzers – The ultimate list

Fuzzing – OWASP

Amazon.com: Fuzzing: Brute Force Vulnerability Discovery: Michael …

22C3: Fuzzing

Wfuzz – A Tool for Bruteforcing/Fuzzing Web Applications | Darknet …

These links should give you plenty of materials and links to tools. I would highly encourage any security folks to set up a small lab, try the tools and just learn a bit about breaking applications. You will be surprised at how easy it is and how much insight it will give you into information security. Give it a shot and let me know how it goes!
