How to Crack Software by Modifying DLL Files: 7 Steps

  • If you want to crack most software, you will need to have a good grasp on assembly , which is a low-level programming language.Assembly is derived from machine language, and each assembly language is specific to the type of computer you are using. Most assembly language is expressed through binary and hexadecimal

    To examine and modify DLLs, you will need several different tools, including a disassembler. IDA Pro is a great option, as it’s a disassembler and debugger. Fortunately there’s a free version available from https://www.hex-rays.com/products/ida/support/download_freeware , although it’s much more limited in functionality than the Pro version. You can also try dotPeek , which is a DLL-supporting decompiler that decompiles .NET assembly code to C#.Another option is OllyDBG , which lets you open DLL files for free.

    The process is a little different depending on which disassembler you’re using. This will show you what DLL files are being loaded by the program. Use the debugger to examine which functions are being called from the DLL.

    Many programs use a timer for copy protection, and when the timer runs out, the user is no longer able to access the program. The goal is to find this counter code, and then bypass it.

    Set a break-point on the counter. Once you’ve isolated the counter function, set your disassembler to break when it is encountered. This will allow you to look at the exact code that is occurring when the counter function is called.
