4f: The File Format Fuzzing Framework

Check Your Web Security with Acunetix

4f is a file format fuzzing framework. 4f uses modules which are specifications of the targeted binary or text file format that tell it how to fuzz the target application. If 4f detects a crash, it will log crucial information important for allowing the 4f user to reproduce the problem and also debugging information important to deciding the severity of the bug and its exploitability.

4f’s purpose is to find vulnerabilities in code that parses file formats including configuration files.

4f uses specialized modules for fuzzing code that interprets file formats. Several modules are included and more can be written to follow other file formats.

A module system is in place for fuzzing any file format you like as long as you know its specification

Custom debugger gathers crucial debugging information on crash, logs it, then continues fuzzing.
