Explore techniques for enhancing software security through bytecode mutation in this conference talk from Nullcon Goa 2022. Learn about building secure software, protecting against reverse engineering, and implementing advanced security measures like code minification, obfuscation, and encryption. Discover a proposed solution called Mutant, which offers a new high-level programming language for writing secure code and a compiler for protecting existing binaries. Gain insights into constant obfuscation, cross-compilation, encryption methods, and memory capture techniques. Understand the limitations of these approaches and explore key generation strategies for improved software protection.
