This lesson is a simple one to demostrate some stupid routines in hardcoded serials.
Hardcoded serials are serials that are writen into the program thus there is no algo used to calculate the serial. Usaly only one serial but sometimes many are implemented. This kind of protection is stupid and lame. In our target i will demostrate how they use the hardcoded serial trick and you would find its quite the same for many other apps like win rescue.

Load the app and goto registration and enter a bogus serial. Pow they give you a error message saying this isnt a valued serial. Open your hex editor and look for this message in the exe as ASCII. Scroll up and down around it and look for possible strings that could be a serial, usaly ramdom letters and/or numbers. There isnt anything interesting really so try another error messagesearch. The app says its 30 days trial so forward your clock 30 days and run it. now it gives you a new error message. Search for this one in the hex editor.
Ahh now look just above it. 
e8gdy4  <-- hmm
Now try and register the app with this code. It worked! hah. Restart the app to make sure its registered like it says and sure, its still registered. 
Alternativly open win32dasm and disasemble the exe. Look for the message in there and scroll above it and the code also shines apon our dark face.
