Symbolic Execution
Description
This practical course focuses on symbolic execution, more particularly on the Angr framework. Combining a collection of static analysis techniques, it enables one to perform dynamic analysis leveraging so-called symbolic execution of a program. An introduction to the theorem prover Z3 and an overview of concolic testing is covered. Trainees will learn an alternative to tackle obfuscation techniques and runtime security controls using Angr in situations where static analysis is difficult.
Topic covered
angr, z3, symbolic execution, theorem prover,

Code instrumentation with FRIDA
Description
Code instrumentation is a dynamic analysis technique that aims at controlling the behavior of the application's code. With this ability one can passively intercept data transiting between functions or modify the code of a whole function. FRIDA is the swiss army knife of code instrumentation frameworks, and this module will teach trainees how to use it to reverse engineer mobile applications.
Topic covered
code instrumentation, frida, dynamic analysis
Outcome
What you will learn: - What is code instrumentation and why it is useful and complementary to static analysis - How to use FRIDA to instrument the code of an application, and automate tests
Practice
A practical exercise is provided and is part of the a 3-parts exercise. It is a Crackme-like challenge, where FRIDA must be used to analyse an the code of an application at runtime. The main objective in this first part, is to recover an HMAC Key and dump the memory of a Virtual Machine that will be analysed later on.

Reverse engineering a Virtual Machine using Unicorn
Description
Virtualization-based security technique is a popular technique to protect and run sensitive code. The challenge it brings is the additional task of reverse engineering a code implemented with custom instructions in the context of an application protected with multiple layers of protections. In this context lifting the to-be-reverse-engineered code outside and emulating it would be one of the best solution. In this training, trainees will learn to use Unicron with the aim of recovering the custom code of a virtual machine embedded within an application.
Topic covered
code emulation, unicorn, dynamic analysis
Outcome
What you will learn:
Practice
This is the second module of a 3-parts exercise. The trainee will have to use Unicorn in order implement a custom CPU so the code that was recovered from the first part of the exercise can be executed and analysed at runtime. The main objective of the exercise is to reverse engineer the code of a custom virtual machine that is used to execute a custom code that implement sensitive code.

Static Analysis of a virtual machine using GHIDRA
Description
Dynamic and Static analysis techniques are complementary, namely, it is often difficult to only focus on one single type of technique while reverse engineering an application. Dynamic analysis provides a a faster and straightforward approach to get an information. Static analysis is a slower approach but ensures a larger code coverage. If one had to reverse engineer a custom assembly code excuted by a custom virtual machine, being able to disassemble and decompile the code into a more comprehensive code brings the ability to review it without having to execute it. This module focuses on the reverse engineering tool: GHIDRA and its language specification, SLEIGH. The aim of this module is to show how to implement a custom decompiler for a virtual machine.
Topic covered
static analysis, decompiler, ghidra, sleigh
Outcome
What you will learn:
Practice
This is the third and last exercise of a 3-parts exercise. In this module, the trainee will have to use GHIDRA and SLEIGH to implement a decompiler for the virtual machine that has been recovered from the very first part of this exercise. The trainee will understand why static and dynamic analysis are complementary
