| I, {{U|barbieauglend}}, would love to take a look at binaries with you and figure out together what the programs do. They are often a lot easier than you might think!
| |
| | |
| If you want to participate, you will need a laptop (with charger!) and if you have any questions, feel free to contact me under {{mailto|barbieauglend@chaosdorf.de}}.

| Symbolic execution is a powerful tool for code verification, bug hunting, and reverse engineering. In this class, we will dive into the concepts of constraint programming and SMT solvers and how binary analysis tools, such as angr, integrate these concepts into their frameworks. It is going to be a very practical class, where we are going to solve various CTF challenges with the goal of visiting different features of angr.
| |
| | |
| Most CTF players use z3 and angr to save time when solving reverse engineering challenges and that is also the path we are going to take.
| |
| If time is available, we will also check manticore and miasm, two other tools with symbolic execution engines with different features!
| |
| | |
| ==== Requirements for the symbolic execution workshop ====
| |
| | |
| * Be comfortable understanding and writing Python3 code
| |
| * Familiarity with x86/x64 assembly
| |
| * VMware Workstation or Player (at least version 12) (no VirtualBox)
| |
| * At least 40GB of free disk space- At least 8GB of RAM
| |
| * A laptop with administrative privileges
| |
| | |
| ==== Goals ====
| |
|
| |
|
| * Understand how SMT solvers work
| | <br>I [[barbieauglend]] would love to take a look at binaries with you and figure out together what the programs do. They are often a lot easier than you might think! |
| * Understand how symbolic execution works
| |
| * Get all the flags!
| |
|
| |
|
| ==== Materials ==== | | <br>If you want to participate, you will need a Laptop (with charger!) with a Windows7 guest machine. If you don't have it or have problems organizing it, please let me know before the workshop =) We can manage something! And if you have any questions, feel free to contact me under barbieauglend@chaosdorf.de ! |

| === Reverse Engineering for beginners ===
| | Let's dive into the blackhole of compiled code and understand the internals of the software running in our computer. It doesn't matter if you want to fix a broken gadget or safe your files (now you know why backup right!) from a ransomware, it is elementary to understand how they work. This is Reverse Engineering (RE), and it is done every day from recreating outdated and incompatible software, understanding malicious code, or exploiting weaknesses in software. |
