i used to read in newspapers that many young hackers in US and russia were able to breach/ hack into well-protected organizations like CIA, satellites and even MIR. I never understood hacking. I presume that the hackers might be using portable advanced 10 GHz speed computers with satellite connections, then only it would be possible to breach in the electronic machinery! Presidents might be carrying nuclear codes, but i think many advanced countries have given many of its hackers freedom to breach! That means many satellites controlled by hackers can get images, then many security cams get a third-person hack, then many submarines/aeroplanes get virtual control, many missiles system have been hacked. Its no more a geek world, only an unstable world!
