Some guys are way smarter than me. One such techy discovered that when you use a password locking schem in many PLCs there is an exchange of data (read password) between the software and the hardware AND it is the hardware that sends the password for the software to verify. What it means is that your software initiates a verification of the password which has been writen in a PLC memory area. The PLC send the password to the software application running in your PC/Laptop and this is where the match is verified. You only need to snoop the com port to find it. To do so, you will need to practice a little but its not that hard to do. I for one would never have found this. But then again I would not need to. Brute force is less artistic but still works.
