Well, +DataPimp has indeed "specialised" in CD-ROM protections,
yet he has
now started to work on this 'related'
cracking subject! Well, you would not have thought that some 'so called' dongles
just check THEIR OWN PRESENCE ON THE PORTS... would you? And yet, look here!
An easy (yet important) further step!
Cracking NetXRay 1.1.3
(A Very Easy Dongle Protection)

Yes dongles, there was only two dongle essays there and since
I contributed to the Cd-Check essays I would have to say that I wanted
to contribute this to project as well. I would have to say that this is
my first dongle and I was able to defeat it's protection within a matter
of about 1 or 2 minutes. This software is not freely downloadable, but
you can -if you like- find it on the internet, it is the same exact
version that was released by PWA.
OK, so you have the software, let's get going so we can run this
software and see what it looks like. Ok, after you have installed the
program go ahead and run it, you will see a msg box pop up with a message
saying the 'protect key' was not found, and some other junk telling you
to contact them etc.
Ok, now we are not going to use Soft-Ice on this at all, we are
going to decompile the "netxray.exe" file and view it's code.
Once you have decompiled it, we are going to search for the string
"sorry". You will notice that it is found rather quickly, and this
is the code we find:
