Fuzzing with multiple servers in parallel: AFL++ with Network File Systems

Introduction When fuzzing large-scale applications, using a single server (even with 4 64-core AMD Ryzen CPUs) may not be powerful enough by itself. That’s where parallelized/distributed fuzzing comes in (i.e. automatic sharing of results between fuzzing systems). In this guide, we’ll take a look at how to set up multiple servers fuzzing the same program using AFL++, linked all together with an NFS (Network File System).
