The IDA Pro Book: The Unofficial Guide to the World's Most Popular Disassembler
Format: PDF / Kindle (mobi) / ePub
No source code? No problem. With IDA Pro, the interactive disassembler, you live in a source code-optional world. IDA can automatically analyze the millions of opcodes that make up an executable and present you with a disassembly. But at that point, your work is just beginning. With The IDA Pro Book, you'll learn how to turn that mountain of mnemonics into something you can actually use.
Hailed by the creator of IDA Pro as "profound, comprehensive, and accurate," the second edition of The IDA Pro Book covers everything from the very first steps to advanced automation techniques. You'll find complete coverage of IDA's new Qt-based user interface, as well as increased coverage of the IDA debugger, the Bochs debugger, and IDA scripting (especially using IDAPython). But because humans are still smarter than computers, you'll even learn how to use IDA's latest interactive and scriptable interfaces to your advantage.
Save time and effort as you learn to:
- Navigate, comment, and modify disassembly
- Identify known library routines, so you can focus your analysis on other areas of the code
- Use code graphing to quickly make sense of cross references and function calls
- Extend IDA to support new processors and filetypes using the SDK
- Explore popular plug-ins that make writing IDA scripts easier, allow collaborative reverse engineering, and much more
- Use IDA's built-in debugger to tackle hostile and obfuscated code
Whether you're analyzing malware, conducting vulnerability research, or reverse engineering software, a mastery of IDA is crucial to your success. Take your skills to the next level with this 2nd edition of The IDA Pro Book.
activation. Each time a plug-in is activated in this way, IDA passes control to the plug-in by calling PLUGIN.run. An alternate method for plug-in activation is for the plug-in to hook into IDA’s event-notification system. In such cases, a plug-in must express interest in one or more types of IDA events and register a callback function to be called by IDA when any event of interest occurs. When it is time for a plug-in to be unloaded, IDA calls PLUGIN.term (assuming it is non-NULL). The
netnodes, where that data could later be retrieved by the processor module. An alternative approach is to build a loader that does nothing other than recognize .pyc files and then tells the processor module that it should handle all of the other loading tasks, in which case the processor will surely know how to locate all of the information needed for disassembling the .pyc file. IDA facilitates the construction of tightly coupled loaders and processor modules by allowing a loader to defer all
useful when developing exploits for format string vulnerabilities. As an example, consider the following short code fragment in which the fprintf function is invoked with a user-supplied buffer provided as the format string. .text:080488CA lea eax, [ebp+format] .text:080488D0 mov [esp+4], eax ; format .text:080488D4 mov eax, [ebp+stream] .text:080488DA mov [esp], eax ; stream .text:080488DD call _fprintf In this example, only two arguments are passed to fprintf, a file pointer and the
binary form only, it is very difficult for competitors to create software that can interoperate with it or to provide plug-in replacements for that software. A common example is driver code released for hardware that is supported on only one platform. When a vendor is slow to support or, worse yet, refuses to support the use of its hardware with alternative platforms, substantial reverse engineering effort may be required in order to develop software drivers to support the hardware. In these
create (or edit) a file named .Xmodmap in your home directory (something like /Users/idabook/.Xmodmap) containing the following commands: clear Mod1 keycode 66 = Alt_L keycode 69 = Alt_R add Mod1 = Alt_L add Mod1 = Alt_R The default X11 startup script (/etc/X11/xinit/xinitrc) contains commands to read .Xmodmap whenever you launch X11. If you have created your own .xinitrc file, which overrides the default xinitrc, you should make sure that it contains a command such as the following;
