There are many different ways to protect your code from being reversed. There are a litany of packers and virtualization techniques, as well as anti-debugging, anti-disassembly, and anti-virtualization approaches that can protect your code from nosy reversers. However, there are also a number of ways around each of these techniques. As protections get better, so do reversers. Also, many of these techniques exist at the binary level, and will not protect your source code if necessary. During this talk, I will discuss some of the protection techniques that exist, from malware authors to current mainstream software authors. In addition, I'll demonstrate a multi-language source code obfuscation tool I've created for the purposes of protection. This tool makes reversing and understanding the purpose of your code drastically harder via obfuscation and other anti-reversing methods.
