Using Control-Flow Techniques in a Security Context: A Survey on Common Prototypes and Their Common Weakness

Practical approaches using control-flow techniques in order to detect changes in the control-flow of a program have been subject of many scientific works. This work focuses on three common tools making use of control- and data-flow analysis in order to detect alternations and reveals their common weakness in terms of the ability to react directly to a dynamic change in control-flow. With a general focus on static analysis of binaries or source code, detection of dynamic changes in the executive flow cannot be detected. In order to emphasize this shortcoming of static analysis, we present an approach for dynamically changing a program´s control-flow and validate it by depicting a proof of concept.
