University of Reading researcher Mark Gasson has become the first human known to be infected by a computer virus. The virus, infecting a chip implanted in Gasson's hand, passed into a laboratory computer. From there, the infection could have spread into other computer chips found in building access cards. All this was intentional, in an experiment to see how simple radio-frequency identification (RFID) chips like those used for tracking animals can host and spread technological diseases. The research from the British university shows that as implantable bionic devices such as pacemakers get more sophisticated in the years ahead, their security and the safety of the patients whose lives depend on them will become increasingly important, said Gasson. We should start to think of these devices as miniature computers," Gasson said. And just like everyday computers, they can get sick. "I don't think for us that (infectious technological agents) would be a particularly new concept, but implants in our bodies will make it a lot more real," Gasson told TechNewsDaily. "A denial-of-service attack on a pacemaker, if such a thing were possible, would of course be very detrimental."
