That's a great question. Devices that emit RF could be hijacked and turned into signal jammers. With smart jamming attacks, even low-power transmitters could potentially cause serious harmful interference to other devices. Botnets of compromised devices could be especially damaging. Since vulnerabilities are often chained by attackers, sometimes in very unexpected ways, to accomplish their final goal, we think that the FCC has a legitimate interest in just about any vulnerability on a wireless device. But the question of legal authority is itself open for public comment and we hope there's vigorous debate on the record to make sure we get it right.
