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 78)
- updated to 4.07c
- afl-fuzz:
- reverse reading the seeds only on restarts (increases performance)
- new env `AFL_POST_PROCESS_KEEP_ORIGINAL` to keep the orignal
data before post process on finds (for atnwalk custom mutator)
- new env `AFL_IGNORE_PROBLEMS_COVERAGE` to ignore coverage from
loaded libs after forkserver initialization (required by Mozilla)
- afl-cc:
- added @responsefile support
- new env `AFL_LLVM_LTO_SKIPINIT` to support the AFL++ based WASM
(https://github.com/fgsect/WAFL) project
- error and print help if afl-clan-lto is used with lto=thin
- rewrote our PCGUARD pass to be compatible with LLVM 15+ shenanigans,
requires LLVM 13+ now instead of 10.0.1+
- fallback to native LLVM PCGUARD if our PCGUARD is unavailable
- fixed a crash in GCC CMPLOG
- afl-showmap:
- added custom mutator post_process and send support
- add `-I filelist` option, an alternative to `-i in_dir`
- afl-cmin + afl-cmin.bash:
- `-T threads` parallel task support, can be a huge speedup!
- qemu_mode:
- Persistent mode + QASAN support for ppc32 targets by @worksbutnottested
- a new grammar custom mutator atnwalk was submitted by @voidptr127 !
- two new custom mutators are now available:
- TritonDSE in custom_mutators/aflpp_tritondse
- SymQEMU in custom_mutators/symqemu
- removed ppc64le condition (failed parsing), we have no 32bit ppc64le
