These constants are used in the executable to load the string mapped to it. The string evaluation copy appears to be in a string table with the constant 873 mapped to it. Run Resource hacker and open the WinRAR.exe executable. Windows applications can store strings in a string table ‘resource’, so we use a tool to read the string tables of the executable which is called Resource hacker. The string cannot be found, so most likely it is not stored as consecutive characters in the executable. Enter evaluation copy in the search box below. Now you are in the References tab of 圆4dbg. Right click somewhere in the CPU window and goto Search for -> Current module -> String references. You are now in winrar.exe region of the memory shown in the CPU tab. Goto the symbols tab in 圆4dbg and double click the row that contains the winrar.exe module. You want to limit your search to only the Winrar executable and not search all the other modules (DLL’s) that are loaded by the application. In 圆4dbg you can search for strings in the executable. We don’t know what the string will be when the application is registerd, but we know for sure that evaluation copy should not be shown. If you think of how this application was written, somewhere in the code a decision must be made (if/else statement) to show the string evaluation copy instead of something else like registered. The application window states that this is an evaluation copy:
#WINRAR CRACK REGISTRATION#
The registration routine can be found in many ways, but usually a good place to search is for certain strings. The trick is to find that routine and modify it so that the application thinks it is registered. So somewhere in the executable there must be a function (routine in Assembly) that checks if the application is registered. When the application starts it must somehow check if the application is registered. Finding the routine that checks if the application is registered The application is now running without pausing at any break points. Click the right arrow located under the menu in 圆4dbg (or press F9) repeatedly until the text in the lower-left of the window stays at ‘Running’. Now the application is running inside the debugger and it will pause (break) at some address, this is the entry break point. Run 圆4dbg and open the WinRAR.exe executable in 圆4dbg by pressing F3 to open a file. for address 00007FF6A403AE4A only check if 4A is the same. Only the last couple of bytes should be the same. Memory addresses mentioned in this tutorial are likely to be different on your system.
