One of the greatest challenges of modern reverse engineering is taking apart and analyzing software protections. During the last decade a vast number of such shell modifiers have appeared. Software Protection as an industry has come a long way simple encryption that protects executable and data parts to current highly sophisticated protections that are packed with tricks aiming at slow down in the reversing process.-One of the greatest challenges of modern reverse engineering is taking apart and analyzing software protections.
