Uncovering Hidden Bugs and Vulnerabilities in C/C++

How to Fuzz Your Code With 3 Commands

What to Expect

CI Fuzz is a solution that lets you run feedback-based fuzz tests from your command line. Every developer can use it to find bugs and vulnerabilities with three simple commands.

In this live stream, our expert Jochen will:

  • Cover the current state of fuzz testing
  • Set up CLI fuzzing within 3 commands
  • Uncover multiple bugs and severe memory corruption vulnerabilities

All code examples and tools used are open-source.

# Initialize fuzzing

$ cifuzz init

# Create your first fuzz test

$ cifuzz create my_fuzz_test

# Run fuzz test and find bugs

$ cifuzz run my_fuzz_test
