Abstract

Advances in reverse engineering and program analyses have made software extremely vulnerable to malicious host attacks. These attacks typically take the form of intellectual property violations, against which the software needs to be protected. The intellectual property that needs to be protected can take on different forms. The software might, e.g., consist itself of proprietary algorithms and datastructures or it could provide controlled access to copyrighted material. Therefore, in recent years, a number of techniques have been explored to protect software. Many of these techniques provide a reasonable level of security against static-only attacks. Many of them however fail to address the problem of dynamic or hybrid static-dynamic attacks. While this type of attack is already commonly used by black-hats, this is one of the first scientific papers to discuss the potential of these attacks through which an attacker can analyze, control and modify a program extensively. The concepts are illustrated through a case study of a recently proposed algorithm for software watermarking [6].
