Benchmark Results

SBFT24 Fuzzing Competetion (mutation test)

🏆 BandFuzz is the winner in the SBFT24 Fuzzing Competition, which use mutation test as the ranking metric. BandFuzz achieved the highest number of mutant kills in total, as well as the highest average mutation score. BandFuzz also achieved the highest coverage of mutants.

Mutation Testing Result (final ranking)

SBFT24 Fuzzing Competetion (FuzzBench)

Due to the 3.5GB memory limitations, 5 out of the 22 targets failed at runtime. However, BandFuzz still achieved a ranking of #2 in terms of coverage (with AFL++ being ranked #1), and it outperformed all other competitors in the test.

BandFuzz versus autofz*

When using the same set of eight common open-source fuzzers, BandFuzz-8 outperformed autofz-8 by an average of 15% in branch coverage. Moreover, despite utilizing fewer fuzzers than autofz-11, BandFuzz-8 achieved an average of 5% higher branch coverage.

*autofz is a SOTA fuzzer-ensemble tool.


(1) What are the benefits of collaborative fuzzing compared to using individual fuzzers?

By combining different fuzzing techniques and tools, we can create a more robust and comprehensive fuzzer. Each fuzzer contributes its unique strengths, such as different mutation algorithms, coverage-guided strategies, or execution environments. The synergy achieved by amalgamating these distinct approaches significantly increases the likelihood of discovering previously elusive software vulnerabilities.

(2) Why does BandFuzz outperform other fuzzer-ensemble tools?

BandFuzz utilizes reinforcement learning algorithms to dynamically choose the most efficient fuzzer for each iteration, based on real-time performance data. This approach minimizes redundant exploration in the search space.
