C++11 Metaprogramming Applied to Software Obfuscation

Explore advanced C++11 metaprogramming techniques applied to software obfuscation in this Black Hat conference talk. Delve into the Turing-complete sub-language of C++ executed at compile time, and learn how to generate obfuscated code without external tools or compiler modifications. Discover methods for introducing randomness to create polymorphic code, with practical examples including string literal encryption and call obfuscation using finite state machines. Gain insights into type safety, optimization based on types, and the generation of pseudo-random numbers at compile time. Examine various implementations, including debugger detection and predicate-based obfuscation, while considering compiler support and real-world applications.

Intro

What is Obfuscation?
Without templates
With C++ templates
Type safety
Optimisation based on types
C++ metaprogramming
Strings literals obfuscation
1st implementation - Problem
