DOES OPTING OUT OF SMART TV TRACKING WORK? RESEARCH FINDS “SUSPICIOUS” TRAFFIC.

Summary from the TLDR InfoSec newsletter

Vizio OS TVs kept sending traffic to an Amazon Kinesis ACR endpoint in every opted-out scenario tested, including while idle, according to a Northeastern University study of eight smart TV OSes across 12 TVs. Samsung's Tizen also kept contacting ACR endpoints after opt-out during first-party streaming, antenna, and HDMI viewing, while Roku's post-opt-out traffic was limited to The Roku Channel and disclosed in its terms. Encryption kept the researchers from confirming what the traffic contained, so the findings pointed to likely rather than proven consent violations.
