Good read/watch on Stuxnet–guaranteed to raise the hair on the back of your neck
A friend of mine, Zeddy Iskandar pointed out an article on Wired (below) about the story of Stuxnet. I just realized that I watched about it on Ted Talks.
Long story short, if you're a geek & or at least remotely interested in technology, these 2 links is a much watch/read. Watch the video above first, and if you still want to know more, read the Wired article below-written almost in the style of a detective novel.
