Stuxnet, Duqu and Flame are the new weapons of warfare. These are the new munitions that attack those systems that have very specific ingredients. The key ingredient of such systems is – well – computer programs. Those little sets of instructions that people call code – not any secret military code – but working instructions for various machines to pass on various flags, messages, symbols, or data to other machines so that certain sequence of operation is started or stopped in a particular deterministic, predictable and pre-defined manner. This is called software, supposedly differentiating these from the machines that typically in military mind are the hardware.
