(description
|

"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.")
