A dynamic detection method against ROP and JOP

As the proposition of the idea of Return-Oriented Programming (ROP), programs will face new challenges from viruses, and many of current defense measures will be ineffective. With fine granularity, covert virus features, deliberate and sophisticated construction and rare static characteristics, ROP attack can circumvent many traditional defense measures and its variant Jump-Oriented Programming (JOP) attack makes lots of current special ROP defense tools lose their effects. Under this circumstance, it´s imperative to discover the dynamic features of ROP exploits. At this time, bringing in the technology of Dynamic Binary Instrumentation (DBI) provides powerful support for dynamic analysis of ROP attack. In this paper, we will introduce a defense measure to ROP attack. By identifying malicious program execution flow and restricting the function call specification of general program libraries, we will prevent the turning-complete features of ROP attack. Our detection method can restrain malicious use of shared libraries by ROP and defend a large part of ROP attacks.
