Press F8 back in the CPU window to force the next step until you get to the TEST EAX.

If the debugger breaks (pauses the program’s execution) after entering your key, then you know you found DLL in step 5.

Resume the program and enter any software key you feel like.

Test to see which one works to break out of the activation loop by right clicking the DLL call and setting a breakpoint for all instances of that call.

By stepping into the function with the debugger, we can examine the registration specifically.

GETDLGITEMTEXT, will be for dialog boxes, which get called when you try to enter a software key.

Right click the CPU window, and click Search For > All intermodular calls.

Click the play button to run the program with the debugger attached.

Open up the program you wish to bypass with ollydbg.

This is to verify that we can come up with the keys. (ollydbg will be used in examples)įirst, run the program that you are attempting to reverse engineer and try to activate it with a random key to verify that you need a valid software key to proceed.

A debugger installed: IDA, ollydbg, etc.

Windows (for examples only, debuggers exist across platforms).

At that point, it’s a test of your morals if you want to use your knowledge for good or bad.

I will not be walking you through how to actually crack a legitimate program, because I can’t just crack a program for demonstration, but the techniques applied to my examples should give you the foundation needed to create your own.

This works because assembly allows you to speak directly to the processor and force a skip over the registration process.In this Null Byte, let’s go over how cracking could work in practice by looking at an example program (a program that serves no purpose other than for me to hack). Using this, you can completely bypass the registration process by making it skip the application’s key code verification process without using a valid key. This is mainly due to computer processes’ ability to be completely manipulated by an assembly debugger. Even with today’s most advanced methods of defeating piracy in place, it is still relatively easy to crack almost any program in the world. If you’ve ever wondered how software pirates can take software and crack it time and time again, even with security in place, this small series is for you.
