Can I use LibAFL as a replacement for libFuzzer?

Yes, LibAFL includes a compatibility layer that allows it to act as a drop-in replacement for libFuzzer-based harnesses.

LibAFL is a modular Rust-based library used to build custom fuzzers with highly specific mutation, feedback, and execution strategies.

Why should I choose LibAFL over AFL++?

You should choose LibAFL when you need deep customization, fine-grained control over internal fuzzer components, or are targeting non-standard environments that general-purpose fuzzers don't support.

What programming languages does LibAFL support?

LibAFL itself is written in Rust, but it can fuzz targets written in C, C++, Rust, and other languages through various instrumentation and executor backends.

Does LibAFL support multi-core fuzzing?

Yes, LibAFL features a launcher and state-sharing mechanism that enables efficient multi-core and parallel fuzzing campaigns out of the box.

セキュリティとテスト

Builds modular, high-performance custom fuzzers using the LibAFL framework for advanced security testing and research.

LibAFL is a highly modular fuzzing library designed for developers and security researchers who need more flexibility than standard tools like AFL++ or libFuzzer provide. Written in Rust, it allows users to assemble custom fuzzers from interchangeable components such as observers, mutators, and schedulers. It is particularly useful for targeting non-standard architectures, implementing novel mutation strategies, or conducting deep fuzzing research while maintaining compatibility with existing libFuzzer harnesses via a drop-in runtime.
