Finding vulnerabilities in software requires in-depth knowledge of different technological stacks. Modern day software’s have a huge codebase and may contain vulnerabilities. Manually verifying such vulnerabilities is a tedious task and may not be possible in all cases. This training is designed in such a way that it introduces the concept of fuzzing and vulnerability discovery in software covering multiple platforms such as Linux & Windows and triage analysis for those vulnerabilities.
During this training, attendees would be emulating techniques which would provide a comprehensive understanding of “Crash, Detect & Triage” of fuzzed binaries or software. In “Deep dive into fuzzing” we will be covering a detailed overview of fuzzing and how it can be beneficial to professionals in uncovering security vulnerabilities with a hands-on approach through focus on labs.

Day 1 

  • Understanding fuzzing fundamentals
  • AFL Internals
  • Setting up the environment
  • Selecting fuzzing targets
  • Spinning up the fuzzer effectively
  • Corpus generation
  • Address/Memory Sanitizers
  • Hooking custom mutators
  • “Not so pro tips” while fuzzing
  • Parallel fuzzing
  • Improving code coverage with grammar
  • Plotting difference in codecoverage
  • Enhancing your fuzzing approach
  • Symbolic execution fuzzing

Day 2 & 3

  • Setting up persistent mode
  • Introduction to QEMU
  • AFL internals for QEMU
  • Targeting Blackbox binaries Introduction to ARM
  • Cross-platform architecture fuzzing
  • Setting up QEMU persistent
  • Introduction to network fuzzing
  • WinAFL Internals
  • Analyzing your target with debuggers
  • Improving code coverage
  • Fuzzing browser engines and SSL libraries
  • Overview of different fuzzing frameworks
  • Integrating slack with fuzzing stats
  • Capture the crash

Key Takeaways

  • Effective ways of fuzzing
  • Understanding the different class of vulnerabilities
  • Key fundamentals of fuzzing and how it works
  • Creating your own grammar for fuzzing
  • Implementing persistence for complex programs
  • Utilizing QEMU for binary only fuzzing

Students will be provided

  • Walkthrough of lab exercises.
  • A dedicated server with custom OS (Windows & Linux) for one month which can be utilized for fuzzing.
  • A private dedicated channel where trainers will be available to answer your queries after the training.
  • Local lab setup (OVA of Ubuntu and Windows) loaded with all the course exercises and material including solutions.
