2019-05-16, 13:30–16:30, Workshop 2
This is a workshop on the open source binary analysis framework angr. We will teach you about its various analyses techniques for reverse engineering and how to integrate them into your workflow.
In this workshop we will present the binary analysis toolkit angr.
We will show it's capabilities for reverse engineering and how to use them to improve your reverse engineering workflow.
This includes both using angr as a standalone tool, how it's features can be integrated into modern tools like IDA, Binary Ninja or radare2 and how to built your own custom tooling on top of it.
We will introduce core concepts like:
- architecture independent analysis
- formalizing instruction behavior
- Reasoning about how some code would behave depending on all its inputs and not just with one specific input
- Formalizing your problem
- Use ~~decades of research in automated theorem proving and constraint solving~~ some Python to solve it
And present problems that can be solved using those concepts in addition to introductory exercises:
- First Hands-On experience with angr
- Thinking about programs symbolically instead of concretely
- automatically finding passwords/keys/backdoors
- Breaking anti-reverse-engineering measures and tricks (e.g. opaque predicates, dead code, obfuscation)
