To this end, I am going to write a series of tutorials on how to write buffer overflows. These are important skills for incident responders and for those attempting to protect their networks. In addition, being able to reproduce buffer overflow exploits will also give you the tools to more accurately assess the risk of discovered vulnerabilities as well as to develop effective countermeasures for exploits out in the wild. Having this knowledge will help you understand the circumstances under which these products can work, will help you troubleshoot when things don't work and will correct unrealistic expectations about what the products are capable of. Make sure the Hex option is checked and the Beginning of File option is checked.Introduction One thing I have always maintained is that aspiring or practicing penetration testers who use an exploitation product (such as CANVAS, Core Impact, Metasploit) should know how buffer overflows actually work. We now want to type in the offset value that we wrote down, in this case 0001A915. Next press CTRL+G to bring up the Goto dialog box, Goto can also be found under Edit. Patching the Bytes: Open up WorldTV2.exe in HexWorkshop. Ignore the “h” at the end it just means that the value is hexadecimal. You should see: Line:52558 Pg 657 and 658 of 1734 Code Data 0001A915h in File WorldTV.exe We are interested in the Offset value of 0001A915h. That information is found at the bottom of the w32dasm window. To do this we will need to find where the jne instruction is located in WorldTv.exe. You should now be at the following lines: Looking at the code we see a test eax,eax followed by a jne 0041B54C We want to change the jne (jump if not equal) to jmp (jump) that way the program will register when you use any serial.

Code of a software program produced in one of the windows in OllyDBG.įinding the Bytes: Lets first try the easy way. For the software companies use of reusable object code development. Software Cracks and Software Cracking: Removing Software Copy Protection. Let’s write that little message down and save it. Ahh, we get a nice little messagebox telling us “Invalid Registration Code”. That is important to note because it lets us know that it is checking for a registration key (maybe a keyfile or registry key) before the program even loads. It goes directly into the nag screen letting us know that it is not registered. Knowing that we will not need to unpack the executable lets us do a little examination of the protection scheme. That will make it all the easier to crack. Surprisingly, the target is not packed or protected. Open up PEiD and drag worldtv2.exe into it. Lets name it worldtv2.exe we will refer to it later It has become habit to first examine a target with PEiD to determine the packer or protector. Go to target folder in our case c: program files worldtv and make a quick backup that we can work on without fear of screwing up the file. Let us first get set up and ready to crack.
