String Encryption as an Obfuscation Tool - Reverse Engineering - Paul (blog.paul-mason.co.nz)

submitted by tivit(364) 2 years, 6 months ago

In the last post we took a look at how to encrypt strings within an assembly to assist in obfuscating our code from prying eyes. In this post we'll take a look at how easy it is to circumvent this feature, essentially making it... well... not as cool as it sounds. Topics we'll cover: * A quick recap of what string encryption did to our assembly * Why is string encryption easy to to circumvent? * A simple method for circumventing this feature * Implementation of circumvention code (reverse engineering?)
