PTrix: Efficient Hardware-Assisted Fuzzing for COTS Binary

Despite its effectiveness in uncovering software defects, American Fuzzy Lop (AFL), one of the best grey-box fuzzers, is inefficient when fuzz-testing source-unavailable programs. AFL's binary-only fuzzing mode, QEMU-AFL, is typically 2-5× slower than its source- available fuzzing mode. The slowdown is largely caused by the heavy dynamic ...More
