We've written in the past about how your TV is probably tracking you, and now Consumer Reports, as part of a broad privacy and security evaluation, has has found that millions of smart TVs are vulnerable to hackers and "raise privacy concerns by collecting very detailed information on their users."

According to the report, the problems affect Samsung televisions, plus models made by TCL and "other brands that use the Roku TV smart TV platform, as well as Roku's popular streaming devices."

"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," Consumer Reports said.

"This could be done over the web, from thousands of miles away."

The good news is these TVs' security vulnerabilities apparently won't allow hackers to spy on you or steal your information, according to Consumer Reports.

The report singled out Samsung, TCL and other Roku TVs as being vulnerable, but smart TVs from LG, Sony and Vizio were also evaluated.
