There are a lot of packers/protectors used to hide the functionality of the software. Sometimes this software is legal, sometimes malicious. It is vital to be able to unpack such software for future investigation. But the main issue is that many commercial protections use different algorithms to make automation of unpacking difficult. We will discuss more advanced techniques that are powerful and can be used to break strong protection. We will talk about debugging without debugging API. Year, it's strange but it's real life.
