Session
Coverage-guided fuzzing is a software testing methodology that is effective at finding vulnerabilities by automatically and continually making small changes to the program's input and observing its effect on the path a program takes. This hands-on workshop aims to give you the tools needed to set up a simple working fuzzing environment for your own targets.
