What does the tool do? The program is a graphical Windows application (Win32 GUI) for the byte-accurate comparison of two executable files (e.g. B. .exe or .dll). The special feature of this is that the binary comparison does not start at the beginning of the file, but at the respective entry point (entry point) of the program code. This allows modifications or patches to be detected in the executable code, even if the file sizes or header metadata differ fundamentally from each other. Core functions & features ⚙️ Intelligent PE header analysis: The tool automatically detects whether it is a 32-bit (PE32) or 64-bit (PE32+) Windows file. It reads the virtual address of the Entry Point (AddressOfEntryPoint) and translates it to the real file offset on the hard drive. 🔍 Synchronized byte comparison: After the offset calculation, the tool jumps exactly to the code start point in both files and compares bytes for byte (via a high-performance file loop) from there. 📏 Ignore size differences: Enable the option “Ignore filesize differences”, the tool compares the data until the shorter of the two files reaches its end. A difference in size therefore does not lead to a premature termination. 📝 Detailed error log (log): Deviations found are output directly in the UI. The tool shows the relative offset (from the entry point) and the absolute offset for both files separately, including the different hex values (e.g. B. 0x90 ! = 0xCC). To keep the log readable, the maximum of the first 30 Differences listed.

Goal : Find valid username & serial Compiler : C++ Platform : x64-Windows Packed : No Specification : Internal private obfuscation Rule : don't patch binary Note : there is no asymmetric encryption , so you can find it.

So this is my first upload - I hope I am doing this right. I have included all the protections in the screenshots being used. Good luck

I want you guys who are capable of unvirtualizing and unpacking them to upload the final ones. These files are just the same part of the codes virtualized which are 2 lines of the original mfc source codes. So if you can unvirtualize them and unpack them, please upload the final ones. Any other protections are excluded absolutely. Give it a try and improve your skills. Best Regards. sean.

OllyDbg is a 32-bit assembler level analysing debugger for Microsoft® Windows®. Emphasis on binary code analysis makes it particularly useful in cases where source is unavailable. OllyDbg is a shareware, but you can download and use it for free. Special highlights are: Intuitive user interface, no cryptical commands Code analysis - traces registers, recognizes procedures, loops, API calls, switches, tables, constants and strings Directly loads and debugs DLLs Object file scanning - locates routines from object files and libraries Allows for user-defined labels, comments and function descriptions Understands debugging information in Borland® format Saves patches between sessions, writes them back to executable file and updates fixups Open architecture - many third-party plugins are available No installation - no trash in registry or system directories Debugs multithread applications Attaches to running programs Configurable disassembler, supports both MASM and IDEAL formats MMX, 3DNow! and SSE data types and instructions, including Athlon extensions Full UNICODE support Dynamically recognizes ASCII and UNICODE strings - also in Delphi format! Recognizes complex code constructs, like call to jump to procedure Decodes calls to more than 1900 standard API and 400 C functions Gives context-sensitive help on API functions from external help file Sets conditional, logging, memory and hardware breakpoints Traces program execution, logs arguments of known functions Shows fixups Dynamically traces stack frames Searches for imprecise commands and masked binary sequences Searches whole allocated memory Finds references to constant or address range Examines and modifies memory, sets breakpoints and pauses program on-the-fly Assembles commands into the shortest binary form Starts from the floppy disk and much, much more!
