Hospital rooms beep and flash with many devices that are increasingly getting infected with malware (see “Computer Viruses Are ‘Rampant’ on Medical Devices in Hospitals”). But for several reasons, these gadgets are often incompatible with commercial security software.
Now, new technology developed by academic researchers could catch most malware on the devices just by noting subtle changes in their power consumption. This could give hospitals a quick way to spot equipment with dangerous vulnerabilities and take the machines offline. The technology could also apply to computer workstations used in industrial control settings such as power plants.
