Hi folks, its been a long time since I have sầu posted some thing technical, so I will be writing about the challenge I got at NIT KU, where I cracked WinRAR 3.80 using a disassembler & will tell you the same here. You can craông xã any version of WinRAR using this method và need not to pay for the registration fee and you can vì this all by your self, easily. Furthermore, major software are cracked using the same way,but just get a bit complex in the methodology. This tutorial is intended for those who are new lớn cracking & disassembling.

In any case you disagree with the above sầu statement, stop here.

The Tools

To perform this haông xã you will be needing –

Any De-assembler (I use Hackers Disassembler & Hview )Resource HackerA patch Creator ( Use Universal Patch Creator or Code fusion)

You will be able lớn get them by googling or you can download my set of tools provided.

How to Crack ?

You need lớn have sầu a bit knowledge of assembly language,and in case you don’t have it,just cram the steps and it will work anytime,every time. Download the lakiểm tra version of WinRAR from their website and install it. I will be cracking Winrar 3.80 here (cuz I already have it:P. ). This is basically a 2 step process ( 4 step ,if you want khổng lồ vị things with a professional touch,period) .

*

Now copy the WinRAR.exe file to lớn desktop. Make a copy of it there.

Step 1 – Hunting for Memory Address

Now load Hackers Disasembler và load the copy in it.

*

The Disassembler will disassemble the executable in assembly code. Now you need to search for strings that are used in WinRAR program. Press Ctrl + F & type “evaluation” without quotes & search in the assembly code. Hit enter…

*

After you have reached this block of code by searching, just look at the blochồng of code above it. There you will find that some assembly values are being compared & then code is jumped lớn some other function. Now see carefully, the “evaluation copy” function must be invoked after some specific condition is met. We need khổng lồ look for it at the code and the make certain changes lớn the condition so that the program doesn’t checks for the condition.

*

In the above code you can see this code –

00444B6A: 803DF4B84B0000 cmp byte ptr <004BB8F4>, 0000444B71: 0F859B000000 JNE 00444C12This is the code responsible for validating you as a legal user :) . Just note down the memory address that leads to lớn jump (JNE) at some memory location. In this case, note down 00444B71.

cảnh báo : For any WinRAR version, this code & memory address might be different,but the JNE will be same. Just note down the respective memory address that checks.

Now you need to search for the code that brings that ugly nag screen “Please purchase WinRAR license” after your trial period of 40 days is over. For this,look over your toolbar & cliông xã on “D” which stands for looking for Dialog references.

*

Now in the dialog box that opens,tìm kiếm for “please” and you will get the reference as – ID-REMINDER, “Please purchase WinRAR license”

*

Double click on it & you will reach the subsequent code.

*

The code will be something like

* String: “REMINDER”0048731A: 68EB5E4B00 push 004B5EEBJust note the memory address that invokes the REMINDER dialog. In this case its 0048731A. chú ý it down. lưu ý : For any WinRAR version, this code và memory address might be different.But the Reminder Memory address code will always PUSH something. Just note down the respective memory address that PUSH ‘s.

Step 2 – Fixing và Patching

Now in this step we will be patching up values of memory addresses we noted earlier. I will be doing this using HVIEW. Now load the copy you disassembled in Hacker’s Disassembler in Hview.

*

After you have loaded it, you will see the code is unreadable. Its just like opening an EXE tệp tin in notepad. You need lớn decode it. To vị that, just press F4 and yoiu will get an option to lớn decode it. Hit DECODE and you will be able to see code in the size of assembly code & memory addresses.

*


After you have done that, you need to lớn tìm kiếm for memory addresses you noted down earlier. Just hit F5 and a search box will be there. Now you need to enter the memory address. To vị that, enter a “.” and the type memory address neglecting the earlier “00” . The “.” will suffice for “00”. ie – Type .444B71 in place of 00444B71

*

& tìm kiếm in the code.

*

After you have sầu reached the respective sầu code, you need khổng lồ make changes to lớn it. Press F3 and you will be able to edit the code.Now make the following changes –

*

After you have sầu done it, save it by pressing F9. Now tìm kiếm for next memory location by pressing F5 and entering it. Reach there & make the following changes by pressing F3 –

*

Save the changes by pressing F9 and exit HVIEW by pressing F10. Congrats…You have cracked WinRAR :) Replace the original WinRAR.exe cộ with this copyofwinrar.exe cộ by renaming it. It will work 100% fine :P

Step 3 – Spicing up the EXE

Now U have sầu a 100% working version of EXE, you might want to change your registration information in WinRAR. TO vì chưng this, you can use Resource hacker.

*

Launch Resource tin tặc, load the copyofwinrar.exe pháo in it

*

Now go lớn DIALOG –> Expvà tree –> ABOUTRARDLG and cliông xã it. Now Find Trial copy line và replace it with your favorite one :P

*

và clichồng on Compile Script button.

*

Now save the tệp tin with any name on your desktop or any location what so ever.

*

Now you have sầu a fully patched WinRAR.exe pháo file :)) you can either use it, or also can distribute it lượt thích a real cracker. If you want khổng lồ learn that, move sầu on to lớn next step.

Step 4 – Creating a working Patch (or giving Professional touch :P )

I will be using diablo2oo2’s Universal Patcher (UPE) for creating the patch. The patch will work like any authentic one for that WinRAR version. Just lượt thích the one U downloaded at anytime of your life from any Craông chồng & Keyren trang web. Launch Patch Creator and cliông chồng on add new project. Enter project Information & click on save sầu.

*

Click on Add – > Offset patch

*

After you have sầu done that, double clichồng on offmix patch & then

Give sầu path of original winrar.exeGive path of unmodified Winrar.exe pháo (again)Give sầu path for fully patched Winrar.exe pháo (ie Cracked Winrar.exe in this case)Cliông chồng on compare and it will show difference between both filesClick on save sầu.

*

Now in the next window, click on Create Patch and save it. The Patch will be created. Now copy it in WinRAR installation directory and hit on patch, it WILL

*

Congrats you have sầu created a patch of your own & have learned to lớn crack WinRAR :)

*

You can crachồng other software in the same way…just practice, debug and disassemble and you will get the way :)
