Samsung and Roku Smart TVs Vulnerable To Hacking, Consumer Reports Finds (consumerreports.org) 102

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.

      Best thing to do is return the product. Manufacturers keep data on returns, and if they see a significant number coming back because "user rejected EULA" they will do something about it.

      Check your local laws too. In the UK you don't have to return the original packaging at all, or you can just wrap it in parcel tape for transport so that it can't be re-used. Make sure that the return costs them as much as possible and they can't just throw it back on the shelf.

        "Best thing to do is return the product."

        No, best thing is some people bind together and sue their asses. Software shrinkwrap licenses are at least based on the belief that copyright prevents a user from installing the software without agreement.

        Not so much with a phone or IoT device - the user isn't copying anything, and has no need to agree to anything. There is no "consideration" to create a contract. There's nothing which legally prevents a purchaser from using a device without accepting terms. If you're sold a phone or IoT for some function, and they want you to agree to some terms before using it, after you've already bought it, that seems a perfect example of an attempt to create an unconscionable contract of adhesion. Same with, say, GM and OnStar tracking (they never explain how they know if a car has been sold, or what allows them to track the second purchaser).

        When one of those things comes up on the screen, cover it with a sticky note saying "This is my device, and I'll use it as I please. By clicking continue, I retain all rights."

          I remember AMD graphics cards always had a note at the top of the EULA stating that if you didn't agree to it you should return the card to the retailer for a full refund.

          That text was in a little text file you could edit. You could make the EULA say anything you wanted, then click "I agree". Be interesting to know what the legal status of editing the EULA in that manner would be, and if the software accepting you "I agree" click counted as AMD accepting your terms.

      • Best thing to do is return the product.

        A) That will never happen in any meaningful scale.
        B) A better thing to do is to simply not connect the device to a network if you don't have a compelling need to do so. Can't be hacked if it can't be reached.
        C) Another better thing to do is for some enterprising lawyer(s) to sue them until they get the message. EULA be damned lawsuits will cost them money even if they win so eventually it becomes cheaper to actually provide real security.
        D) EULA that you don't agree to prior to purchase are on thin legal

      LG, Sony and Samsung cripple their devices unless you agree to the T&C as part of the setting procedure, and they all report back to base with regular network traffic. They will not operate on your LAN without external net access, if you block the mothership domains at the firewall, you'll be locked out of third party services like, Netflix, Hulu, etc, in addition to denying access to your local NAS media with lying network errors.

    • Two or three things:

      1. Don't buy a so-called 'smart TV' in the first place. They're still out there.
      2. If you must buy a 'smart TV', only connect it to the Internet long enough to get through their shitty 'agreement', then disconnect it.
      2a. If it insists on being connected: block it's IP address on your router. 3. Alternately: Call the manufacturer help line. Tell them you have no Internet at home. There has to be a way to 'activate' the TV without the internet.

        I'm surprised no-one has done a Kickstarter for a firewall appliance dedicated to TVs and other IoT devices. It would block all incoming connections and only allow outgoing ones to a whitelist of approved domains. You could have an app that lets you enable specific services like YouTube and Netflix, but nothing else.

        As an added bonus it could block ads on services like YouTube.

        • You can do that from your router already.

          If you are talking about an app you can install on your TV to do this, most smart TVs don't let you sideload apps and would probably never allow such an app in their official app store

Even when it's ostensibly turned off? Are you an exhibitionist, or do you just not understand what's going on here?

    Gary Ellison - February 7, 2018

    Consumer Reports issued a report saying that Roku TVs and players are vulnerable to hacking. This is a mischaracterization of a feature. It is unfortunate that the feature was reported in this way. We want to assure our customers that there is no security risk.

    Roku enables third-party developers to create remote control applications that consumers can use to control their Roku products. This is achieved through the use of an open interface that Roku designed and published. There is no security risk to our customers’ accounts or the Roku platform with the use of this API. In addition, consumers can turn off this feature on their Roku player or Roku TV by going to Settings>System>Advanced System Settings>External Control>Disabled.

    In addition the article discusses the use of ACR (Automatic Content Recognition). We took a different approach from other companies to ensure consumers have the choice to opt-in. ACR is not enabled by default on Roku TVs. Consumers must activate it. And if they choose to use the feature it can be disabled at any time. To disable consumers have to uncheck Settings > Privacy > Smart TV experience > Use info from TV inputs.

    We take the security of our platform and the privacy of our users very seriously.

    Happy Streaming!

    They're like lots of IOT devices - wide open on the local network for nefarious things like cranking up the volume. Not so much for the exaggerated claim that it can be done from the Internet. That's not happening unless you went out of your way to specifically configure your NAT gateway to allow incoming connections to your TV, in which case it's your own damn fault.

    Sure, Roku and some others (a number of AVR [wikipedia.org]s come to mind) and have no security, but in practical terms, it's only a matter of annoyance.

    Reminds me on the time Consumer's Report dinged VW for only having a single turn signal "blinker" indicator on the dashboard, instead of two (showing left/right). Only an idiot CR reviewer wouldn't remember which way they wanted to turn and need a reminder.

        Unfortunately, there are so many unsecured devices out there that the router is the only thing keeping things secure. From your stupid $15 IoT WiFi nanny camera to multi-million dollar machines. Fortunately, routers and switches with greater security and greater features are out there for reasonable prices now to deal with it. But you're right, if the router is compromised, all those devices are vulnerable.
