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 Blog, 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. It is also useful for programmers to ensure that their program is running as intended, and for malware analysis purposes.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. For cracking and reverse engineering, it is often the primary tool because of its ease of use and availability any 32-bit executable can be used by the debugger and edited in bitcode/assembly in realtime. It is often used by crackers to crack software made by other developers. OllyDbg is often used for reverse engineering of programs. The disassembler part of OllyDbg is free software, released under the GNU General Public License. The source code can be purchased from the author. In version 2.x, the registration requirement was dropped. The software is free of cost, but the shareware license of version 1.x requires users to register with the author.
