(Source: Reuters)  There is a very effective computer virus
called Stuxnet, Last time, I mentioned it caused a nuclear
accident in Iran. To be more specific, the Stuxnet virus
attacked the underground uranium centrifuge plant at Natanz, in
Iran.  This incredibly well-crafted virus took its
manufacturers, and we still don't know who they are, at least 10
person-years to make.  Once Stuxnet was inside the computers
that controlled the spinning centrifuges, it made copies of
itself and spread to all the computers on the internal network
at the underground centrifuge plant.  The virus then looked for
a specific set of widely used software, with the fairly obscure
name of Simatic WinCC Step 7. This software could be used to
control the action of high-speed motors.  Then
