The U.S. Department of Homeland Security has jumped into the debate over whether medical devices are vulnerable to hacking. They are at risk, the agency has decided, and it has issued a warning on some of those specific threats, entitled "Attack Surface: Healthcare and Public Health Sector." As eWeek reports, the warning notes that medical devices connected to IT networks (like insulin pumps and defibrillators) are vulnerable to the spread of malware and data loss. But mobile devices (think smartphones and tablets) also pose risks, the warning stipulates, because they are vulnerable to spreading malware while connected to medical IT networks. Meanwhile, a board that advises the U.S. government on security issues is urging the lawmakers to expand the FDA's ability to evaluate how secure, wireless medical devices are against hacking as part of the regular approval process.
