Also, static analysis can be used to explore the data flows within analyzed software. This type of program analysis helps reverse engineers investigate the overall control flow of the code and allows them to understand the sequences in which particular pieces of code get executed. Static analysis investigates code with no regard to its execution or input. How to Search for Vulnerabilities in Embedded Software Using static analysis for reverse engineering automation Allow for the needed level of interactivity so the reverse engineer could rename functions, variables, arguments, etc.Recognize file formats to accurately map code and data to virtual address spaces.Recognize high-level language constructions: functions, variables, calling conventions, cycles, switches, etc.Disassemble the code of up to several dozen CPU architectures.However, such a tool had to be able to accomplish at least four major tasks: The need to assess the security of embedded devices and other products relying on uncommon microcontrollers created demand for a new kind of tool for automating reverse engineering. But it soon became apparent that nobody could tell for sure if these MCUs were secure enough. New microcontroller unit (MCU) architectures like NXP ColdFire offered a larger variety of features at a more affordable price than common architectures, making them extremely popular, especially among manufacturers of embedded devices. Related services Professional Reverse Engineeringīut with time, more and more devices started relying on uncommon microcontrollers. Software engineers had neither the tools nor the need to perform reverse engineering for these architectures. Other architectures like Tricore, RH850, and MIPS were usually ignored. Most reverse engineers focused their efforts on studying a very limited circle of architectures, since most applications used one of the following three: Back then, we had no tools or techniques for reverse engineering automation and had to recognize high-level entities in binary code on our own. Reverse engineering has come a long way from disassembling code with a pen and notepad in the beginning of the 90s to using automated analysis tools and decompilers to improve security and speed up software development.Įven about ten years ago, the possibility to reverse engineer software depended strongly on the reverser’s knowledge of a processor’s architecture, compiler specifics, and the operating system. Software reverse engineering, or backwards engineering, is the process of exploring the way a piece of software works by analyzing its code.
