Many papers have discussed hacking into a process control system. Very few papers talk about what to do after control of the process has been achieved. This paper will cover miniaturizing attack coded into a pressure sensor. The code will setup a standing wave in a piping structure by sensing the pressure wave caused by a water hammer and operating a valve in such a way that the pressure wave increases with each pass. The first part will cover a set of algorithms that are very small capable of sensing the process. The second part will cover efficiently inserting the code into the microcontroller’s firmware.
