American fuzzy lop is a security-oriented fuzzer
American fuzzy lop is a security-oriented fuzzer that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary. This substantially improves the functional coverage for the fuzzed code. The compact synthesized corpora produced by the tool are also useful for seeding other, more labor- or resource-intensive testing regimes down the road.
Compared to other instrumented fuzzers, afl-fuzz is designed to be practical: it has modest performance overhead, uses a variety of highly effective fuzzing strategies and effort minimization tricks, requires essentially no configuration, and seamlessly handles complex, real-world use cases - say, common image parsing or file compression libraries.

(revision 55)
- updated to 3.0c
- llvm_mode/ and gcc_plugin/ moved to instrumentation/
- examples/ renamed to utils/
- moved libdislocator, libtokencap and qdbi_mode to utils/
- all compilers combined to afl-cc which emulates the previous ones
- afl-llvm/gcc-rt.o merged into afl-compiler-rt.o
- afl-fuzz
- not specifying -M or -S will now auto-set "-S default"
- deterministic fuzzing is now disabled by default and can be enabled with
-D. It is still enabled by default for -M.
- a new seed selection was implemented that uses weighted randoms based on
a schedule performance score, which is much better that the previous
walk the whole queue approach. Select the old mode with -Z (auto enabled
with -M)
- Marcel Boehme submitted a patch that improves all AFFast schedules :)
- the default schedule is now FAST
- memory limits are now disabled by default, set them with -m if required
- rpc.statsd support, for stats and charts, by Edznux, thanks a lot!
- reading testcases from -i now descends into subdirectories
- allow the -x command line option up to 4 times
- loaded extras now have a duplication protection
- If test cases are too large we do a partial read on the maximum
supported size
- longer seeds with the same trace information will now be ignored
for fuzzing but still be used for splicing
- crashing seeds are now not prohibiting a run anymore but are
skipped - they are used for splicing, though
- update MOpt for expanded havoc modes
- setting the env var AFL_NO_AUTODICT will not load an LTO autodictionary
- added NO_SPLICING compile option and makefile define (forwarded request 855999 from msmeissn)
