Worries that someone could hijack your TV with a broadcast have been present for decades (ever see The Outer Limits?), and it's clear that they're not going away any time soon. Oneconsult security researcher Rafael Scheel has outlined an attack that can control smart TVs by embedding code into digital (specifically, DVB-T) over-the-air broadcasts. The intrusion takes advantage of flaws in a set's web browser to get root-level access and issue virtually any command. You only need to have a transmission powerful enough to reach compatible TVs, and at least one attack will work without revealing that something is wrong.
