Workshop: Reversing Rust Binaries: One step beyond strings

Workshops are first-come, first-serve and have limited capacity. Some workshops may be streamed for additional passive participation.

Are you a seasoned reverse engineer, but you tremble when a Rust binary lands on your desk? When you encounter a Rust binary, do you just run strings on it and hope for the best?

We will take a single problem - string recovery from a Rust binary - and uses it as an approachable starting point for exploring reversing Rust binaries. We will cover:

  • What are the practical steps we need to take to recover strings? How are strings represented in memory, passed between functions, and manipulated throughout the program?

  • Once we recover the strings, what do the strings mean? What can the strings we recover tell us about the compiler, language runtime, standard library, and third-party libraries in the binary?

This workshop is intended for reverse engineers and malware analysts who are familiar with reversing C or C++ binaries, but who are unfamiliar with the Rust programming language.
