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

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.

    In fact, one TV requires that you accept a broad privacy policy during setup before you can use the most basic, internet-free functions, such as watching TV using an antenna.

    This is exactly the kind of stuff many of us have expected to happen and it'll most likely happen more and more in the future; companies see you as a product and whatever they sell you is still their property in their view, not yours. Don't want to be spied on? Tough shit, it's not your decision!

      "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."

      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.

      Everyone: There are some cases where the 'herd' has made decisions for everyone and it makes it almost impossible to take back your privacy and protect your data, but in many cases it's just a matter of whether you're willing to not be lazy about it and find a way around things. Just don't listen to people that claim it's 'impossible' and that you should just 'give up and accept it', they're either fools, cowards, or both.

    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!

    2. Re: From Roku by UnknowingFool · · Score: 3, Informative

      No what the rebuttal misconstrues and gets wrong from Consumer Reports criticism is not that Roku has an API for 3rd party developers but that the API itself is unsecured.

      The problem we found involved the application programming interface, or API, the program that lets developers make their own products work with the Roku platform. “Roku devices have a totally unsecured remote control API enabled by default,” says Eason Goodale, Disconnect’s lead engineer. “This means that even extremely unsophisticated hackers can take control of Rokus. It’s less of a locked door and more of a see-through curtain next to a neon ‘We’re open!’ sign.” And, it turned out we weren’t the first to notice this: The unsecured API had been discussed in online programming forums since 2015.

      Also the advice given by Roku is already addressed in the article. Disabling External Control will prevent hacking however it also disables Roku's own app.

      A Roku spokeswoman said via email, “There is no security risk to our customers’ accounts or the Roku platform with the use of this API,” and pointed out that the External Control feature can be turned off in the settings. However, this will also disable control of the device through Roku’s own app.

      But then you're just moving the security from one device (the television) to another (the router). So if a vulnerability is found in your router, perhaps a zero-day exploit for which a patch isn't available for several weeks, then your television is vulnerable as well. You might say something like "If your router is hacked, have have bigger problems than the fact that someone can control your TV!" That may be true, but it misses the point. There is NO GOOD REASON why televisions need to be designed in such a way that they are vulnerable to this kind of hacking, especially if people don't really want or need a lot of "smart TV" features, i.e. just watching over the air broadcasts, or DVD/BluRay discs, or playing video games. This is why I don't like smart TVs. A separate TV and streaming box is much safer and more flexible.

      I get it, tons of IOT things are vulnerable to remote hijacking of various types. But I'm not worried about someone changing my volume - I'm sorry for them if that's how they spend their time. This all reminds me of the PSAs on the Justice Network, which are all just a nice cop smiling and telling you to be deathly afraid every time you do things like walk across a parking lot or use an ATM. Be cautious, of course, but if you're afraid all the time then the hackers/terrorists are winning.

    If someone can get to your smart TV behind your LAN what stops them from getting to whatever other shit exists behind same LAN? Why is it necessary to hack TV as a jumping off point?

    For example say someone with your home WiFi password installs Mr Clean's malware app on their smart phone. What prevents the app from attacking your systems directly without the smart TV foothold?

    What access scenario in TFA is necessarily limited to smart TV?

    If you've owned someones router sufficiently to get onto their LAN, why would you bother with their TV? There are way richer targets on the average home network.

    To quote the article:

    To become a victim of a real-world attack, a TV user would need to be using a phone or laptop running on the same WiFi network as the television, and then visit a site or download a mobile app with malicious code.

    Yeah, if you can get someone to do that, you've already compromised the device they installed the application on and have full access to their LAN. Why bother futzing with their TV volume: start harvesting passwords from network traffic or trying to exploit other PCs on the LAN.

    This looks like it is going after the unsecured API that lets you send YouTube videos from your phone to Rokus on the the same LAN segment. Unless you are hanging your streaming devices out on the public internet with routable IPs and no firewall it's not a huge issue.
