AFL++ fuzzing tips that make every test cycle count
Tips for more effective fuzz testing with AFL++
A practical guide to getting more out of AFL++, the widely used coverage-guided fuzzer. The advice covers tuning the harness, managing corpus and dictionaries, and steering the fuzzer toward deeper code paths so each run finds real bugs instead of burning cycles. The focus is on small configuration choices that compound into noticeably better coverage and faster crash discovery.
Effective fuzzing is less about raw throughput and more about giving the fuzzer the right starting point and the right feedback.
