Fuzzing Firefox using In-process Fuzzing with Frida

As asked by a lot of you, today’s blogpost is about browser security. First I will show how to download easily Firefox compiled with AddressSanitizer (ASAN). Then, I will show how to use Frida to list all modules and exports of Firefox. I will show some other interesting scripts and finally, I will demonstrate how to operate in-process fuzzing i.e. modifying the data provided to a given function.

You will get access of the complete tutorial with source code, cheat sheet and or complete video tutorial right below or at this address.

I hope you will appreciate and you can discover more about my courses here.
