An anonymous reader quotes a Report from Consumer Reports: Consumer Reports has found that millions of smart TVs can be controlled by hackers exploiting easy-to-find security flaws. The problems affect Samsung televisions, along with models made by TCL and other brands that use the Roku TV smart-TV platform, as well as streaming devices such as the Roku Ultra. We found that a relatively unsophisticated hacker could change channels, play offensive content, or crank up the volume, which might be deeply unsettling to someone who didn't understand what was happening. This could be done over the web, from thousands of miles away. (These vulnerabilities would not allow a hacker to spy on the user or steal information.) The findings were part of a broad privacy and security evaluation, led by Consumer Reports, of smart TVs from top brands that also included LG, Sony, and Vizio. The testing also found that all these TVs raised privacy concerns by collecting very detailed information on their users. Consumers can limit the data collection. But they have to give up a lot of the TVs' functionality -- and know the right buttons to click and settings to look for.
