Introduction
In this tutorial we learn how to install afl++ on Kali Linux.
What is afl++
afl++ is:
American fuzzy lop is a fuzzer that employs 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.
afl++-fuzz is designed to be practical: it has modest performance
overhead, uses a variety of highly effective fuzzing strategies, requires
essentially no configuration, and seamlessly handles complex, real-world use
cases – say, common image parsing or file compression libraries.
afl++ is a fork of the unmaintained afl.
