A bulletin published by the Department of Homeland Security has warned that the increasing use of wireless networking technology to enable medical devices expands the ways that those devices could be hacked. The bulletin, published May 4 by DHS’ National Cybersecurity and Communications Integration Center, warns that advances in medical devices, including Internet connectivity and the use of smartphones, tablets and other mobile devices in patient care “expands the attack surface” of medical devices. “Smartphones and tablets are mini computers with instant access to the internet or linked directly to a hospital’s network. The device or the network could be infected with malware designed to steal medical information if not upgraded with the latest anti-virus and spy-ware software,” DHS said. Advances in medical device technology have already greatly improved medical care, especially in areas like medical health records and remote monitoring of patients with implantable medical devices. However, too little […]

On the surface, the kinds of industrial control systems that run a power plant or factory floor are very different from, say, a drug infusion pump sitting bedside in a hospital intensive care unit. But two security researchers say that many of these systems have two important things in common: they’re manufactured by the same company, and contain many of the same critical software security problems. In a presentation at gathering of industrial control security experts in Florida, researchers Billy Rios and Terry McCorkle said an informal audit of medical devices from major manufacturers, including Philips showed that medical devices have many of the same kinds of software security holes found in industrial control system (ICS) software from the same firms. The research suggests that lax coding practices may be institutionalized within the firms, amplifying their effects.
