Byron is a source code fuzzer designed to support assembly and high-level languages. It starts by generating a set of random programs, which are then iteratively improved by an evolutionary algorithm. Internally, it encodes candidate solutions as typed, directed multigraphs, and can effectively handle complex, realistic structures containing local and global variables, conditional and looping statements, and subroutines.
Programs can be evaluated using a user-defined Python function or an external tool, such as an interpreter or a simulator. Different types of parallelization are supported out of the box, from simple multithreading to the creation of temporary directories where multiple subprocesses are concurrently spawned.
⚠️ Byron is currently in alpha and under active development
As simple as
pip install --upgrade byron
A few dependencies can enhance Byron functionalities, but are not strictly required. You can get them all with
pip install --upgrade "byron[full]"
None yet, but some HOWTO's and examples are available in the development repo.
