This demonstration crack is a brief example of a real-world application of a very simple bitstream, which was found in the Proteus 8 Security Demonstration Software. It demonstrates that there are many tools available to an attacker who has obtained access to the software. The tools have been divided into the categories below: - Disassemblers and Hex Editors: Disassemblers can provide an attacker with valuable information such as how programs work and how they interact. Because many existing program executables are often obfuscated for security reasons, disassemblers can also allow attackers to bypass those protections without too much effort. By using a hex editor, attackers can also search for sensitive data that may be stored in the program executable. Attacks that involve disassemblers and hex editors are simple yet very effective. - Debuggers: Debuggers are hugely valuable tools during the reverse engineering process. In order to allow access to all program registers and memory addresses an attacker can load a program into a debugger and run it with breakpoints enabled in order to monitor the state of the application at any time. This is most useful when analysing a program's behaviour in specific sections of code, for instance before and after a certain function is executed. On x86 processors, debuggers are often found loaded with advanced features that allow attackers to run programs under them for an extended period of time. These tools are especially powerful when attacking 32-bit operating systems, as they do not require any extra configuration or "hacking" before they can be used. - Ollydbg: A debugger with many useful features that is often used by attackers. It has been around for a long time and can be very useful in most reverse engineering scenarios. - Proteus 8 Function Hooker: An example of a tool that can be used to make minor changes to the behaviour of a program whilst it is running. This is one of the most powerful reverse engineering techniques, as it allows an attacker to modify almost anything that the program does without any changes to its source code. The Function Hooker demonstrated in this demonstration crack was used to change the way that Proteus 8 handles file paths (pathnames), which reduces the length of filenames and renames files with a .mp3 extension. - Proteus 8 Dumper: A tool that can extract data from an application's memory. It can be very useful, as most applications store sensitive information in their memory (such as usernames and passwords). - Proteus 8 Password Extractor: A tool that can extract strings from protected areas of memory. It is very effective when an attacker is not able to run a program under a debugger or when they are looking for accounts that have been set with default passwords. - Proteus 8 Graphical Hooker: A tool that can make minor changes to the way in which Proteus 8 displays its graphics. The purpose of this was to demonstrate how easy it is to modify the behavior of a program without making any changes to its source code. - Proteus 8 Structural Hooker: A tool used to change the layout of data structures in memory. cfa1e77820
