How to crack any licensed software Generally these accounts get shut down following complaints after a few days, and not in a way that would allow you to control a game.

Steps

Learn Assembly programming. In order 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.

2Edit step

Gather your tools. In order to examine and modify DLLs, you will need several different tools. W32DASM is a software disassembler that allows you to pick apart programs. SoftIce is a Windows debugging tool. You ll also want a good coding text editor, such as UltraEdit or Notepad.

3Edit step

Start the program you want to crack with W32DASM. This will show you what DLL files are being loaded by the program. Use W32DASM to examine which functions are being called from the DLL.

Find the counter function. 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.

If the program you are cracking uses a different form of protection, you will need to look for that instead.

5Edit step

Set a break-point on the counter. Once you ve isolated the counter function, set SoftIce 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.

6Edit step

Change the counter code. Now that you ve found the code for the counter function, you can change the code so that the counter never reaches the point where it shuts you out of the program. For example, you could make it so that the counter cannot count up to the break limit or you can bypass the counter by jumping over it.

Some months ago, I participated in something like a Hacker Competition to get a job in a CERT. One of the tests consisted of getting the serial key of a simple program. The organizer sent me an executable called reversing_test.exe

We are going to work with OllyDbg v1.10. You can download this awesome tool from here: OllyDbg v1.10.

You can see its details in the picture below.

The first thing I usually do in these cases is to check if the executable is compressed or not. Some programs pack some of their codes in order to limit our attempt to statically analyze it. To achieve this purpose we are going to use PeID. In the picture below you can see that the program does not detect any compression Nothing found . If the file were compressed with UPX for example, the program would advise us about it and we could uncompress it with this tool.

If we click on the EP Section bottom, we will see some executable s details.

We can see the R. Size Raw Size 400 and the V.Size Virtual Size 350 are

similar in . text . The. text section contains the instructions that the CPU executes and it should be the only section that includes the code. If some day you detect that the R.Size is 0 and the V.Size is 1000 for

example, it would be an indicator that the executable is compressed because in the disk it

does not have any size it is packed and in the memory it has a size it is unpacked itself.

Now we have the assurance that the file has not been compressed. This is one of the first steps in a static analysis. We are going to make a dynamic analysis with OllyDbg but I want to know if the developer has made an effort in order to try to hide some code. Notice if the executable is packed then we are not going to be able to read a lot of strings within the file. It is possible I will talk about that in future posts

The next step would be to run the program by double clicking on the executable. After that, we can see that a MS-DOS window is launched and the program requires us to type the serial number. We type a sentence in order to check the program s behavior.

We have not figured out the serial number It seems logical

Now, we are going to run OllyDbg. It does not need installation, just download it and uncompress it. When OllyDbg is opened, just load the executable clicking on File - Open.

Now we can see the binary code. Don t worry, remember this post is focused on beginners. We are going to click on the play button in order to run the executable just loaded in our debugger and check the file behaviour.

The program has started and we can see the firsts strings like Press ENTER to finish

Please, click on the picture to see the entire details

But Something happens The program doesn t require us to type the serial number like it occurs when we open the application without using a debugger It s really strange It s like the program knows about our intentions and it is closed by itself when we try to run it with a debugger tool

If we reload the file again on OllyDbg, one line of the code draws our attention The program is calling to the IsDebuggerPresent API.

If we seek this API on Microsoft we can see that This function allows an application to determine whether or not it is being debugged, so that it can modify its behavior.

Ok, the program is closed when it is open within a debugger. There are many options to avoid being detected by this technique To achieve this purpose we are going to use the Hide Debugger 1.2.4 plugin. Just download it and uncompress the DLL in the same OllyDbg s folder.

It is necessary to restart OllyDbg in order to work with this plugin. If you click on Plugins tab you can see Hide Debugger plugin. You don t need to do anything else.

We have just installed the plugin to avoid being detected and now, we are going to load and play the executable again. Now the program requires typing the serial number. Great news

We are going to type a sentence which will be easily recognizable.

If we come back to OllyDbg we can see our sentence in the Arg1.

If we continue looking for this sentence through the code we can locate the code below. We can see the String2 28939387, the String1 I m going to looking for this sentence in OllyDbg now and the API call CompareStringA.

We can figure out that the executable is comparing these strings to each other in order for you to check if both have the same value. We can suppose that the string 28939387 is serial number.

OllyDbg offers us to copy the value of this line by left clicking on the line we are interested in.

Then, we are going to paste the line s value to the notepad and then, we are going to copy only the String2 value: 28939387.

In the end, we just need to try paste the value just copied in our program and Well We have obtained the serial number of our program

This post could be applied to many of the simple programs which have a keygen integrated but it is needed to have more knowledge if you want to crack more complex programs.

This post is focus on show you some techniques using OllyDbg. It is only a game to get more reversing engineer skills to research malware. Please, don t contact me to crack programs, it is illegal I recommend you use to use free software. :P
