It is also possible to add third-party plugins and extensions. It traces registers, recognizes procedures, API calls, switches, tables, constants and strings, as well as locates routines from object files and libraries. The function of heuristic analysis of the stack and recognition of return addresses to the parent procedure is supported.Īdditionally, the software allows you to create individual configuration files for debugging different types of applications. OllyDbg (named after its author, Oleh Yuschuk) is an x86 debugger that emphasizes binary code analysis, which is useful when source code is not available. You have the ability to create simple and conditional breakpoints. With the help of the tool, you can perform step-by-step debugging with logging of the entire process. The application is also able to work with PE headers, which contain information necessary to load the executable file into memory. Moreover, the utility enables you to decrypt program code written in the C language. It is possible to display information in HEX, ASCII or UniCode format.
The debugger includes a code analyzer that detects loops, branches, constants, procedures, tables and lines containing text data. OperationĪfter launching the software, all you need to do is specify the path to the executable file. If you need a dedicated development utility, you may use Visual Studio. The syntax highlighting of the code is also supported. The application features a simple graphical user interface and requires minimal knowledge of the assembly process. For each module (executable file or DLL) it attempts to separate code from data, recognize procedures, locate embedded strings.
OllyDbg is a specialized program for Windows that allows you to debug executable files and dynamic link libraries. Find helpful customer reviews and review ratings for Working with Ollydbg: A Practical Step by Step tutorial at.
