Going beyond the issues of analyzing and optimizing programs as well as creating the means of protecting information, this guide takes on the programming problem of, once having found holes in a program, how to go about disassembling it without its source code. Covered are the hacking methods used to analyze programs using a debugger and disassembler. These methods include virtual functions, local and global variables, branching, loops, objects and their hierarchy, and mathematical operators. Also covered are methods of fighting disassemblers, self-modifying code in operating systems, and executing code in the stack. Advanced disassembler topics such as optimizing compilers and movable code are discussed as well.
Going beyond the issues of analyzing and optimizing programs as well as creating the means of protecting information, this guide takes on the programming problem of how to go about disassembling a program with holes without its source code. Detailing hacking methods used to analyze programs using a debugger and disassembler such as virtual functions, local and global variables, branching, loops, objects and their hierarchy, and mathematical operators, this guide covers methods of fighting disassemblers, self-modifying code in operating systems, and executing code in the stack. Advanced disassembler topics such as optimizing compilers and movable code are discussed as well, and a CD-ROM that contains illustrations and the source codes for the programs is also included.
This book describes how software code analysis tools such as IDA Pro are used to disassemble programs written in high-level languages and recognise different elements of disassembled code in order to debug applications in less time. Also described are the basics of Assembly language programming (MASM) and the system and format of commands for the Intel microprocessor. Aspects of disassembling, analysing, and debugging software code are considered in detail, and an overview of contemporary disassemblers and debuggers used when analysing executable code is provided. The basics of working with these tools and their operating principles are also included, and emphasis is placed on analysing software code and identifying the main structure of those languages in which they were written.
Why study programming? Ethical gray hat hackers should study programming and learn as much about the subject as possible in order to find vulnerabilities in programs and get them fixed before unethical hackers take advantage of them. It is very much a foot race: if the vulnerability exists, who will find it first? The purpose of this chapter is to give you the survival skills necessary to understand upcoming chapters and later find the holes in software before the black hats do. In this chapter, we cover the following topics: • C programming language • Computer memory • Intel processors • Assembly language basics • Debugging with gdb • Python survival skills
The Hardware Hacking Handbook takes you deep inside embedded devices to show how different kinds of attacks work, then guides you through each hack on real hardware. Embedded devices are chip-size microcomputers small enough to be included in the structure of the object they control, and they’re everywhere—in phones, cars, credit cards, laptops, medical equipment, even critical infrastructure. This means understanding their security is critical. The Hardware Hacking Handbook takes you deep inside different types of embedded systems, revealing the designs, components, security limits, and reverse-engineering challenges you need to know for executing effective hardware attacks. Written with wit and infused with hands-on lab experiments, this handbook puts you in the role of an attacker interested in breaking security to do good. Starting with a crash course on the architecture of embedded devices, threat modeling, and attack trees, you’ll go on to explore hardware interfaces, ports and communication protocols, electrical signaling, tips for analyzing firmware images, and more. Along the way, you’ll use a home testing lab to perform fault-injection, side-channel (SCA), and simple and differential power analysis (SPA/DPA) attacks on a variety of real devices, such as a crypto wallet. The authors also share insights into real-life attacks on embedded systems, including Sony’s PlayStation 3, the Xbox 360, and Philips Hue lights, and provide an appendix of the equipment needed for your hardware hacking lab – like a multimeter and an oscilloscope – with options for every type of budget. You’ll learn: How to model security threats, using attacker profiles, assets, objectives, and countermeasures Electrical basics that will help you understand communication interfaces, signaling, and measurement How to identify injection points for executing clock, voltage, electromagnetic, laser, and body-biasing fault attacks, as well as practical injection tips How to use timing and power analysis attacks to extract passwords and cryptographic keys Techniques for leveling up both simple and differential power analysis, from practical measurement tips to filtering, processing, and visualization Whether you’re an industry engineer tasked with understanding these attacks, a student starting out in the field, or an electronics hobbyist curious about replicating existing work, The Hardware Hacking Handbook is an indispensable resource – one you’ll always want to have onhand.
