DEF CON 27 - The JOP ROCKET A Supremely Wicked Tool for JOP Gadget Discovery

Talk by Dr Bramwell Brizendine Return-oriented Programming (ROP) has been the predominate code-reuse attack for over a decade, but there are other options. Many mitigations can detect ROP due to heuristics, but these fail to detect Jump-oriented Programming (JOP). The JOP ROCKET is a reverse engineering framework dedicated to facilitating JOP exploits. It allows hackers to discover JOP gadgets. This includes dispatcher gadget's, which helps to subvert and direct the control flow, and functional gadgets, our primitives. This tool provides numerous options to give hackers flexibility on how to find gadgets, to narrow and expand possibilities. Additionally, the tool uses opcode-splitting to discover many unintended gadgets. All gadgets are classified based on operation as well as registers used and affected. Thus, hackers could easily obtain the desired functional gadgets, such as MOV EBX, [VALUE], using simple language commands. Because of JOP's much more complex set up, the tool provides this classification, so time isn’t wasted hunting through results. JOP is rarely done in the wild. Part of that complexity is in set up, but another part is the lack of dedicated tools. Having to find JOP gadgets manually could be time-consuming and require expertise. JOP ROCKET simplifies that, allowing the JOP gadgets to be found quickly and easily. This talk will give brief content on ROP, and then it introduces JOP and its history. Then we will dive into JOP ROCKET, discussing its features, how to use it to find JOP gadgets, and how to set up your own JOP exploit. We will then demo the tool.
