How to Use W32DASM to Hack Software

W32DASM is a disassembler, a tool that can translate machine language back into assembly language. It is useful for reverse engineering, which means taking software apart and finding out how it works. You can use W32DASM to hack software that requires a license key or a password by modifying its code and bypassing its security checks.

In this article, we will show you how to use W32DASM to hack a simple software that asks for a password. You will need W32DASM and a hex editor, such as HackMan or Hex Workshop. You can download W32DASM from here.[^2^]

Step 1: Open the software with W32DASM

Launch W32DASM and click on the Disassembler menu. Select Open File to Disassemble and browse to the software you want to hack. In our example, we will use a program called Password.exe that asks for a password when you run it.

After you open the file, W32DASM will start disassembling it and show you the assembly code in the main window. You can scroll through the code and look for clues about how the software works.

Step 2: Find the password check routine

The next step is to find the part of the code that checks if the password you enter is correct or not. One way to do this is to search for string data that appears in the software's interface, such as \"Enter password\" or \"Wrong password\".

To search for string data, click on the References menu and select String Data References. A new window will pop up with a list of strings found in the software. You can double-click on any string to jump to its location in the code.

In our example, we will search for \"Enter password\" and double-click on it. This will take us to this line of code:

0040100A . 68 40204000 PUSH OFFSET 00402040 ; ASCII \"Enter password:\"

This means that the software pushes the string \"Enter password:\" onto the stack before displaying it on the screen. If we scroll down a bit, we will see another line of code that pushes another string onto the stack:

0040101F . 68 44204000 PUSH OFFSET 00402044 ; ASCII \"Wrong password!\"

This means that the software pushes the string \"Wrong password!\" onto the stack before displaying it on the screen if you enter an incorrect password. This suggests that between these two lines of code, there is a comparison between the password you enter and the correct password.

Step 3: Identify the correct password

The next step is to identify what is the correct password that the software expects you to enter. To do this, we need to look for a comparison instruction that compares two values and sets a flag based on the result.

In assembly language, there are several comparison instructions, such as CMP, TEST, or SUB. They usually have two operands: one is the source operand and one is the destination operand. The source operand can be a register, a memory address, or an immediate value (a constant). The destination operand can be a register or a memory address.

In our example, we will look for a CMP instruction that compares an immediate value with a memory address or a register. This is because we assume that the correct password is stored as a constant in the code or in the data section of the software.

If we scroll up from where we found \"Wrong password!\", we will see this line of code:

00401018 . 3D 31323334 CMP EAX,34333231

This means that the software compares the value of EAX register with an immediate value of 34333231 in hexadecimal. If we convert this value to ASCII characters, we get \"1234\". This is probably the aa16f39245
