"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.")
