Compare your online OB1 and OB35 with your project, it adds instructions.

According to Symantec, it only attacks the system that is using Profibus to control 2 specific VFD brand types that run at speeds in excess of 900-1000Hz.

i.e. it was specifically developed to attack a nuclear plant in Iran, where hey had detailed info of the project to stop the manufacture of weapons grade uranium.

I would guess it was US or Israel government funded. That's my conspiracy theory for today.

This is what Microsoft suggests that you look for to see if Stuxnet is or has been on your system:
