The Stuxnet worm has created quite a stir lately and has reached headlines of most major news outlets. What makes this worm different from the thousands of other active worms?
Unlike worms and other malware in the past, Stuxnet does not target your average PC sitting on the Internet. Rather, the worm spreads via USB drives and once it infects a machine, it targets a specific industrial control software used by Siemens. Once such a system has been identified, the Stuxnet payload reprograms the PLC (programmable logic control) of the control software and can give new instructions to the actual machinery itself - potentially turning motors on and off, shutting down cooling systems, and other good stuff (sounds like right out of a sci-fi movie right?)
Make no mistake, this is one piece of sophisticated weaponry. All indicators point that Stuxnet was created to attack an Iranian nuclear power plant. The plot thickens.
