PeAR

PeAR is a versatile binary instrumentation tool leveraging the GTIRB framework, designed to add AFL++ or WinAFL instrumentation to x64 Linux and x86/x64 Windows binaries, as well as coverage tracing for x64/ARM64 Linux binaries. Key features include multiplatform support, preservation of original binary properties, the ability to import Ghidra function names into stripped binaries, and advanced fuzzing options such as persistent and shared memory modes. PeAR is particularly effective for real-world binaries, even those that are stripped, enabling practical application in binary fuzzing and tracing.
