One of the first cyber incidents was caused by an insect (a moth, in fact). Ever since then, the lower life forms have been trying to disrupt the virtual landscapes we construct for our users. As our virtual environments have evolved to be more complex, these other life forms have always evolved sufficiently to find new cracks in our defenses. As we continue down the current path we are reminded ... More
