Title: Slaying the RE dragon: Mastering Reverse Engineering
Duration: 2 Days
Dates: 9th - 10th October 2019


Have you ever looked at programs and wondered how do they function? How to analyze and debug the operating system and malware? Found a bug, got infected by malware?

We will try to answer these questions with fun tasks while learning the methods, tools we need in the process.


Day 1 - Basics

This day focuses on bringing each participant to the same level of comfort and understanding of the underlying systems

  • Introduction and recap of the homework - binary/file format internals, linkers/loaders, os internals, virtual address space, general assembly gotchas, basic x86{64}, trivia and jargons
  • Mapping assembly to a higher level code in C/C++, Common pitfalls in C++ reversing
  • Putting theory into practice, Reconnaissance to understanding target.
    • System monitoring techniques
    • Working with your favourite disassemblers and various static analysis tools to understand program properties
    • Understanding control and data flow - basic blocks, cfg and other program elements
    • Tracing program execution, basic debugging and tracing

Day 2 - Analysis - Static and Dynamic

This day focuses on solving various tasks involved during day to day malware/vulnerability analysis, acquiring intermediate skills needed to reverse engineer complex software. This day will focus on tracing, scripting, automating analysis and writing your own tools.

  • Case study 1: Crash analysis to understand vulnerability root cause?
    • Understanding the reason of application crash? Backtracking to understand entry of the application  
    • How to analyze crashes?
      • Fixing symbols
      • Source-to-symbol mapping
      • Figuring out data structures
      • Fix?

What to Expect?

Interesting and functional solution to challenges involved in the reverse engineering workflow.

Who should attend

  • Cyber Security Experts, Penetration Testers, Cyber Security Analyst


  • Knowledge with assembly and file formats is preferred
  • A combination of C/C++ and Python to write tools

What to Bring

  • Laptop with admin privileges
  • VMware Workstation or VMPlayer
  • Minimum 50 GB of storage.
  • Minimum 4 GB RAM for virtual machines.
