Researchers have demonstrated how sonic and ultrasonic signals (inaudible to human) can be used to cause physical damage to hard drives just by playing ultrasonic sounds through a target computer’s own built-in speaker or by exploiting a speaker near the targeted device. Similar research was conducted last year by a group of researchers from Princeton and Purdue University, who demonstrated a denial-of-service (DoS) attack against HDDs by exploiting a physical phenomenon called acoustic resonance.… Read more

Now security researchers are warning that one group of sophisticated hackers has amassed a collection of malware-infected routers that could be used as a powerful tool to spread havoc across the internet, or simply triggered to implode networks across the globe.… Read more
