SANS Institute accepted my GWAPT Gold Paper about Unix-style approach to web application testing, the paper is now published in the Reading Room.

The paper introduces several problems I’ve been facing while testing web applications, which converged in a common direction. Burp Suite is known by most and used by many professionals in this field, and while it’s extensible, writing such bits of software have a higher barrier of entry than the budgets of some project would allow for a one-off throwaway tool. Our solution, Piper is introduced through real-world examples to demonstrate its usage and the fact that it’s worth using it. I tried showing alternatives to each subset of the functionality to stimulate critical thinking in the minds of fellow penetration testers, since this tool is not a silver bullet either. By describing the landscape in a thorough manner, I hope everyone can learn to pick the best tool for the job, which might or might not be Piper.

Unix-style approach to web application testing

The accompanying code is available on GitHub. For those who prefer video content, only have 2 minutes, or find the whole idea too abstract, we made a short demonstration of the basic features below. If you’re interested in deeper internals, there’s also a longer, 45-minutes talk about it.
