google/oss-fuzz-gen
LLM powered fuzzing via OSS-Fuzz.
This framework helps software security teams automate and enhance their fuzz testing efforts by using Large Language Models (LLMs) to generate new fuzz targets for C, C++, Java, and Python projects. It takes existing project code and an LLM as input, then outputs new fuzzing code and detailed reports on its effectiveness, including crash discovery and code coverage. This is intended for security engineers and quality assurance professionals focused on identifying vulnerabilities in open-source and proprietary software.
1,372 stars.
Use this if you need to generate novel and effective fuzz targets for your C, C++, Java, or Python projects to uncover hard-to-find bugs and increase code coverage beyond what manual efforts or existing fuzzers provide.
Not ideal if you are looking for an out-of-the-box bug reporting tool without needing to integrate and manage fuzzing infrastructure.
