Automated Black-Box Fuzzer

Offensive Security Completed

Overview

Built a sophisticated black-box fuzzer targeting 64-bit Linux ELF binaries. The fuzzer implements hybrid mutation strategies including bit-flipping and null-byte injection, along with format-specific mutators for JSON, XML, PDF, JPEG, and ELF inputs. Designed to surface memory corruption vulnerabilities such as Heap Use-After-Free and Invalid Writes — applicable to embedded and firmware security contexts.

Key Features

  • ▸ Hybrid mutation strategies (bit-flipping, null-byte injection)
  • ▸ Format-specific mutators for JSON, XML, PDF, JPEG, ELF
  • ▸ Heap UAF and Invalid Write detection
  • ▸ 64-bit Linux ELF binary targeting
  • ▸ Embedded/firmware security testing support
