|
|
American fuzzy lop is a 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.
