AFTER A VERY LONG Time blogged up…with this very new post on reverse engineering!!!
Today…we are going to learn how to crack a simple application…i.e an EXE file!!!!
Note: All Experiments are for only Educational Purposes. Dont Try hard.
Most of you might have encountered a scenario where the software you installed asks for the SERIAL key or LICENSE key!!! THIS IS ANNOYING ! :)
So…how to go about this….??????
Well, today most of the softwares are well secured and well-proofed from reverse engineering! But still…some aren’t!
This is a very simple tutorial which will let you a know a basic approach towards cracking a simple exe file…
SO LET US START!
1. This is a simple application which asks us for the license key..
2. We need to install a disassembler software to crack this application.
3. You may use any disassembler you want..
4. I am using IDA PRO Link Below
5. Install it and launch the application….you will see the following window after launching it.
6. Drag and drop your exe file into the panel…
7. Choose “load file as” MS-DOS Executable…click OK and Continue.
8. By default its IDA View-A…Please choose “HEX VIEW-A”
9. Scroll down to find the line saying ” ENTER YOUR LICENSE KEY” (different for different applications,in my case it is this).
10. Some where near that we found “Google” word next to the line saying “ENTER THE LICENSE KEY”..
11. AWESOME THIS IS our LICENSE KEY!!! :P
12. Let us try “Google” as our key!
13. YEAH!!! IT WORKED!!!!
Ain’t that aweosme!!! try building your own application and reverse engineer it to crack it!
THANKS! :)
