A Samsung smart TV owner expressed frustration over ads being displayed on their 2022 model's Smart Hub, despite not using any additional Samsung services. The owner had previously blocked the ads using a Pi-hole instance, but the ads reappeared after changes to their homelab and networking setup. The incident coincided with the eMudhra CA certificate issue, which involved a compromised private key being added to the open-source mitmproxy project, allowing for potential manipulation of HTTP(S) network traffic, including ad blocking on devices like the Samsung smart TV.
