I strongly advise everyone against ever giving their smart tv the wifi password.

I have about a thousand times more confidence, that if I use my smart TV as a dumb screen connected to an Xbox one or PlayStation 4, that over a multi-year period of time, Microsoft and Sony will successfully keep their operating systems automatically patched, updated, and secure. As compared to any tv manufacturer.

I have seen people resort to things like installing pihole on their home LAN so that their smart tv will stop showing ads covering 1/3 of the screen whenever they use the menus. At least the advertisements that one will see on the home screen of an Xbox or Playstation are relatively small, unobtrusive, and can be ignored without bother.

In the future I think we will have problems with the fact that hdmi can also carry 100Mbps ethernet. Imagine if you plug your smart tv into some other device, intending just to send video to it, that gives it a dhcp lease and default route out to the internet. All in the name of consumer friendly "just plug it in and it works!" type functionality.

They could eventually use ethernet over HDMI or simply include a cellular modem of some sort. The profit is there.

But a simpler solution that we are already seeing a bit is to simply require a network connection to function at all; for now, it's just a periodic check, but a persistent connection requirement is all but inevitable in the medium term.

Devices having cellular modems isn't something new. Many cars already ship with them, for various purposes. WiFi will likely remain in use with smart TVs for a while as video content is data intensive so not really well suited for cellular, but likely stuff like your dishwasher or your stove might include cellular modems in the near future. The data they transmit is limited and you make setup easier as you don't have to type in a WiFi password any more.

Difference between a car & a dishwasher is that a car is typically outside (at least during use) which would help it to get a signal.

Anecdotally inside my house, phones generally get no/weak cell service but WiFi is accessible anywhere in the house.

Obviously they could include both, but if it were relying only on cellular, my washing machine quite possibly couldn't get a connection

Re:Opening Up the Samsung Q60 Series Smart TV (2019) by cosmie on Thursday January 28, 2021 @01:07PM (#25946038)
Carriers run IoT-specific networks[1], which are optimized for use cases such as telematics (low power consumption, low bandwidth usage, but high penetration and coverage). So it's entirely likely that your washing machine would be able to happily send along telematic data via the same carrier your cell phone can't even establish a connection to.

There’s no business model where the STB wants to route Internet traffic on behalf of the TV. Ads on the TV compete with the STB.

> or simply include a cellular modem of some sort.

Yes, an ad platform running over the lower bandwidth but cheap IoT service could justify including this hardware.

Of course, leaving it unconfigured with the open access point has its own risks, given the password is hard-coded to 1111122222: https://twitter.com/silascutler/status/1354521609692995585

I have a Samsung smart TV from mid-2017 and it does not appear to be broadcasting a visible SSID, nor a hidden one. Presumably that has changed in the past couple of years?

if it remains in that terribly insecure state by default until you give it a connection to a network, unfortunately the only thing to do might be to give it the password to a $20 mikrotik wifi router (in a 20MHz 2.4GHz channel) as an AP, so as to not pollute the empty radio channel spectrum in your house, that has no connection to the outside world. What an ugly hack.

Or give it the password to a secondary ssid set up on your main wifi, that goes to a dead end VLAN with no route to anywhere.

Re:Opening Up the Samsung Q60 Series Smart TV (2019) by krastanov on Wednesday January 27, 2021 @11:00PM (#25937980)
Or desolder the (chip) antena which is usually easy notice on the board.
Re:Opening Up the Samsung Q60 Series Smart TV (2019) by foepys on Thursday January 28, 2021 @12:48AM (#25938676)
Aren't Samsung's QLED TV remotes Bluetooth only? Cutting the antenna would then also disable the remote and a modern TV without a remote is pretty useless.
Re:Opening Up the Samsung Q60 Series Smart TV (2019) by tonyedgecombe on Thursday January 28, 2021 @07:37AM (#25941045)
It's clear that the only solution is not to buy a TV.
Re:Opening Up the Samsung Q60 Series Smart TV (2019) by kawsper on Thursday January 28, 2021 @08:25AM (#25941437)
Couldn't desoldering the antenna lead to it overheating and damaging components?
Re:Opening Up the Samsung Q60 Series Smart TV (2019) by krastanov on Thursday January 28, 2021 @07:47PM (#25951979)
Not really. 10 minutes of practice with some scrap wires would give enough soldering skills to remove it safely. The sibling comment about the Bluetooth remote worries me more

I have a dumb Toshiba TV, it's snappy, just plug in HDMI and it works. No loading times, no bloat, no ads, no Automated Content Recognition), not using my network when I don't want to...

I invite everyone to buy dumb stuff, because if we don't, there won't be any market signal, and there all be smart TV, Fridges and so on. I don't have to explain to HN audience why this poses risks, problems, and the probability of intrusive ad ecosystem causing problems with stuff that should just work.

It's important that tech communities like this one push for it.

I treat those devices and untrusted by putting them in a separate subnet that cannot talk to the subnet where I have my other devices (computer, printer, smartphones, etc).

I fear that when Amazon Sidewalk opens up to third parties, there will be no stopping devices, in fact I would imagine that Amazon could share the wifi passwords it collects with all Sidewalk devices.

Iirc, 5G is going to solve this problem: TVs will directly connect to a 5G network, without bothering the user with WiFi matters.
Re:Opening Up the Samsung Q60 Series Smart TV (2019) by grishka on Thursday January 28, 2021 @10:12AM (#25942963)
But who's gonna pay for the data? And what if you disconnect the antenna?
Re:Opening Up the Samsung Q60 Series Smart TV (2019) by frongpik on Thursday January 28, 2021 @10:16AM (#25943026)
TVs will sign a deal with telcos that the latter give access to 5G to certain GUIDs hardcoded in TVs.
Re:Opening Up the Samsung Q60 Series Smart TV (2019) by grishka on Thursday January 28, 2021 @10:33AM (#25943389)
Yeah but it's a potentially perpetual ongoing per-unit cost that the manufacturers will incur for something they sell for a one-time payment. At some point it has to become unprofitable.

There are connected cars but iirc you have to buy a subscription or supply your own sim card to use the online features.

Re:Opening Up the Samsung Q60 Series Smart TV (2019) by labawi on Thursday January 28, 2021 @04:28PM (#25949518)
The connection is there so that they can have a long-lasting income from ads/snooping etc. They can share a bit of the spoils to get the meat.

If specific units are costing them beyond income, they can probably have telcos disconnect them, or just remote-disable the communication.

Re:Opening Up the Samsung Q60 Series Smart TV (2019) by hnburnsy on Thursday January 28, 2021 @02:11PM (#25947297)
Amazon Sidewalk will solve this problem.

How do you feel about a Sony smart TV?

Re:Opening Up the Samsung Q60 Series Smart TV (2019) by Jonnax on Thursday January 28, 2021 @05:19AM (#25940196)
My perspective is that I don't really care.

If my smart TV gets hacked, what are they going to do? Take my Netflix and YouTube credentials?

I've got an LG TV, there aren't huge adverts. It's faster than switching on my PS5 to watch something.

It even has DLNA so I can listen to my music collection off my NAS.

If it starts hacking my network, what's it going to do? Public key SSH is pretty strong. And anything sensitive that could be snooped on would be HTTPS.

So this smart TV hack is going to require a second exploit to get into my windows PC? or Linux boxes?

> My perspective is that I don't really care.

If this screed is just about telegraphing your own wilful disregard for online safety and profound disinterest/absence of knowledge about what a locally connected hostile network device is capable of, then it’s hardly worth responding to.

However, if you’re trying to deliver an implied suggestion that “no-one should care”, then this actively harmful message deserves solid rejection. The consequences range from turning households into spam drones, to placing at-risk folks in physical peril through commoditised surveillance.

It remains an extraordinarily privileged and wonderful thing to live without fear of the capabilities of a corporate- or state-level actor. What’s not so wonderful is being reminded that many folks with this privilege lack the self-awareness to appreciate it.

Re:Opening Up the Samsung Q60 Series Smart TV (2019) by Jonnax on Thursday January 28, 2021 @06:50AM (#25940728)
You're putting words into my mouth. And changing the topic of conversation.

I was responding to someone saying that their smart TV was full of adverts and how it's a requirement to block it. Where the convenience of the utility provided is greater than seeing an advert for a film on the menu page.

You've flipped it around to vulnerable people being surveilled by corporate/state level actors.

Why are Smart TVs singled out here? There's a tons of old Android phones that people use every day with sensitive information that are vulnerable to multiple exploits that will never get a patch.

Or Routers that never get a patch from their Vendor especially if it's a whitebox from an ISP and they've replaced it with a newer model.

It seems like Smart TVs have urban legends associated with them, I asked previously about the supposed "TV connecting to unsecured WIFI" thing that always comes up and nobody had any evidence:

Re:Opening Up the Samsung Q60 Series Smart TV (2019) by TeMPOraL on Thursday January 28, 2021 @06:01AM (#25940472)
A separate subnet is basic hygiene where it comes to IoT, but only a small fraction of IoT buyers have the capability to do that (both in terms of knowledge and having their home network set up in a way that allows this level of end-user control).
Re:Opening Up the Samsung Q60 Series Smart TV (2019) by Jonnax on Thursday January 28, 2021 @06:00AM (#25940469)
Like I said, what are they going to hack into?

And how? So they have an exploit for the smart TV and then another device as well?

Re:Opening Up the Samsung Q60 Series Smart TV (2019) by TeMPOraL on Thursday January 28, 2021 @06:03AM (#25940480)
Your desktop? Your laptop? Whatever you happen to have running in your LAN bound to 0.0.0.0? Quite many things still assume that your local network is more trusted than the wide Internet; breaching a smart TV gives an attacker a beachhead on your local network.
Re:Opening Up the Samsung Q60 Series Smart TV (2019) by Jonnax on Thursday January 28, 2021 @06:23AM (#25940595)
Well those things listening on the local network could also be exploited instead of the TV.

My Desktop/Laptop is supposed to be secured, and patched. Otherwise open wifi access points would be a bad idea.

Personally I think the the idea that the LAN is some walled garden where it's fine to relax security is a bad idea.

> Personally I think the the idea that the LAN is some walled garden where it's fine to relax security is a bad idea.

It is a bad idea, but it happens in practice. For instance, I can vouch for the security of my desktop (except for the times I run some random development stuff bound to 0.0.0.0, for convenient multi-machine access). I can't vouch for the security of my printer, or my IoT bridge. As long as it stays true, someone breaching a single device on your LAN is already creating extra security risk for your other devices.

LG TVs from the past few years involve some level of voice control, so an attacker could be able to remotely turn on your microphone and listen in on conversations.
