Making A Permanent Crack.

Crackme 1 by Brad Soblesky.

By Krobar / Nov 1999


We done well so far. We've checked out a serial number in softice, and found and changed the program code so it would accept any serial.

Now we gonna make a small patch enabling us (or anyone else) to click on it and cause the code to change.

Actually we gonna cheat. We going to use one of the many patch engines available. There many about, and I used a few, but we gonna use Patch Creation Wizard v.1.2 coded by Teraphy/Phrozen crew. It small and does the job. Get it here, then unzip it in a folder and read what Teraphy got to say.

Ok, you back. Now we got everything we need to make a crack...an original unchanged version of crackme1; a patched version of crackme1; and the patch creation wizard.

Now it doesnt matter if everything in the one folder, but sometimes it easier, so copy the two versions (patched and unpatched) of crackme1 into the folder you got Patch creation wizard in...(or copy patch wizard into the folder you got crackme1 in).
I always find it better to copy stuff, instead of shifting it, coz then we still got our original versions in another folder, and we can play round with them some more. Remember, once we've made our crack and tried it out, we wont have an uncracked version anymore. So BACKUP stuff first.

Now click on Patch Creation Wizard, and it open. Click next and it should already be on Byte Patch. If you read the readme that came in the zip, you'll know that thats what we want. Click next, and stick in your name, the name of the crackme, and then browse to where the crackme is ( if you got it in the same folder as patcher then you already there), and click on the uncracked version of the crackme.

Click next and you presented with a screen asking for original file, and patched file. So for original...yeah you got it...browse to, then click on unpatched crackme1. For patched...browse to, then click on patched crackme1. Click next.

Creating patch. Cool. If you copied the crackme.exes into the same folder as the Patch Creation Wizard, you'll notice the addition of the patch in that folder. If you didnt copy them, you'll have to cruise to the folder where they are, and you'll see your new patch.exe there.

Finished. All you got to do is double click the patch (making sure it in the same folder as an unpatched version of crackme1), click patch, and it will write the changes to the crackme1.exe. Now just enter any serial...and ...yep registered.

Thats it for crackme1. I think we gave it a good hammering. Or as I say: we Kro_baR'd it to death.

Next we gonna try a registration scheme that requires a name and serial.
