Most people involved in IT, or IT security will always tell you the greatest threat are usually the people with local access to a machine. This story is not much different but is a proof of concept for an unusual method. Researchers, and would-be attackers, are constantly looking at different means of exploiting vulnerabilities. Sometimes they occur via new and ingenious ways. Sometimes it can be a reapplication of an older, oft forgotten, technique.



Researchers at Duo Security, a part of CISCO, have used one such old technique combined with modern tech. As proof of concept they have shown how to get a workstation GPU to broadcast radio signals. Virtually all electronic equipment emits some kind of electromagnetic ‘noise’. For most, in the age of digital, this is easily mitigated through...
