GamersNexus and LG: Or why rooting your TV is a bad idea

His arguments are all
- yes everyone does this not just lg; :)
- yes it can be used to track the user; but unless you literally go into lg ads hq, you can’t say they don’t
- they rooted to trigger this; well the os and system apps don’t need root, we need it to observe.
If the author is here please consider these as the reasons to why an LG customer would be mad.
- They did not knew LG has an ads subsidiary, whose CEOs and executives constantly go on investor meetings claiming “they own the glass”, “they own the living room”, “they own the network and devices” in the “lg household”
- if the above was said by lg tv division it would have still stung less. This was said by an ad company they didn’t knew existed nor did they agree to be associated with when they bought a home appliance.
Stop focusing on the technical details, look at the larger picture.
There is substance in what they did. But they should have worked with an actual journalist to frame this properly and create pressure on the overarching topics.
If a TV company (LG or ANY of the others who have Ad-subsidiaries) needs to respond to this video, they can easily reframe the whole topic.
The most blatant example is that they demonstrate in the video that this TV, which has a built-in microphone for voice-control, that can be switched off with a mechanical switch:
1. Will record your voice when you ask it to transcribe your input to a textbox
2. Will process your voice to create this text it shows, as visible on the logs of the rooted OS
3. Will SHOW you that it's transcribing your input on the screen.
This is weakening the whole story.
--
In HN-terms: It's a constant-power, constantly-connected IoT-device with lots of sensors and huge compute-power, located in the center of your home.
There are big topics around this that deserve a huge spotlight, which apply to ALL TV manufacturers:
a. What data is actually being collected about the user, and what is done with this data?
b. How well is security handled on the TV to ensure no malicious usage?
Repeatedly jumping to the conclusion during the video that LG specifically is collecting ALL this local data to spy on you, without clear evidence, this just gives LG an easy way to respond and every other vendor enough room to distance themselves from the whole story.
This question implies that the answer could be something other than the maximum amount of data collection and monetization of that data they can get away with.
If that statement gives you pause please spend even a short amount of time reading about ad networks, data brokers, and corporate surveillance.
So even IF that would be a sufficient answer in a court of US, it would not be sufficient in a court of an EU country.
--> Hence my point on how the overall message was diluted too much.
See, you may look at all this as "nothing can be done anyway, so let's bunch it all together and rant about it as emotionally as possible". But I look at it as "this is all potential evidence that a law was either already broken or needs to have a loophole closed"
But you won't get any of this done by spraying all over how normal this is and how everyone does it anyway. You get this done with a precise shot at ONE of them, concise enough to pin them down while aiming at the next one.
Actually I think everything you're suggesting is unclear, LG explicitly say they do these things in their ToS. I skimmed their privacy policy, and I'm pretty sure it essentially says they collect all this information and use it for targeted advertising.
So there's the angle that US is lacking the proper regulation, and the angle that LG may have violated its ToS in the EU.
But neither of this is going to get pinned down if everything is bunched together without focus and clear evidence...
It's either a deliberately contrary or the author has other motives (which may sound ridiculous, but we know that bad actors have been paying people for bad takes for years - Malcolm Gladwell for instance being paid by oil and gas).
Also, I anticipated ads on a smart TV (unfortunately it's inevitable), but (wrongly) assumed that such invasive tracking and "we own the glass" would be a bar too low even for the budget manufacturers.
I'm never buying any LG product ever again.
I also had an LG washing machine. The dispenser plastic drawer broke after a year of use. After over a week of multiple emails and calls with the shop, LG themselves and third-party spares shops trying to get a replacement, I bought a Bosch.
I am also never buying anything from LG again.
May i suggest basic home repair? Two techniques that work in many cases are:
- "welding" with a soldering iron, using cable tie as a filler rod. You'll want good ventilation and a sacrificial tip - epoxy repair putty
Superglue (cyanoacrylate) tends to give disappointing results on its own, but can be a good first step before putty. Putty can be reinforced with some kind of fibre. Never use cyanoacrylate with the welding technique (cyanide).
I don't love the model profusion that makes spare parts markets inefficient, but free markets are inefficient all over the place. Price in the externalities.
Perhaps, but LG has proven problematic to deal with.
To give you an idea, I tried directly with them at first. They gave me an official website to search for the part. It wasn't available. They then game me 2 or 3 third-parties to search. None of them had the part available. I emailed and called. They would at best say "not available".
Eventually I got LG to escalate to a manager, who called me back the next day. The manager was very nice. Told me to go to that official website again. I couldn't find the part. She then instructed me how to navigate to a form on that same website where I could send a message requesting the part. Remember, this is an official LG website.
I sent the form. The next day I got a reply from a third party, telling me they didn't have the part and I should contact the manufacturer directly. Now this is with dirty laundry already accumulating and us risking running out of pants. There's no laundromat near me and I don't have a car, nor I have the time for this crap.
Eventually I found what _could_ be the right part. Only there was no way to be sure it was, and it had a 3-week wait and would cost about 100 quid.
At that point I sat down and calculated how much I paid for the machine, its expected lifetime, deducted the time I had it for to get an estimate "remaining value", and it was less than the time I was wasting with this ordeal, plus everything else if I had to arrange alternative washes for the time being and the price of the replacement part (assuming it was the right one), so it made sense to just buy a new machine and send that one for recycling, so I did that.
> May i suggest basic home repair?
Sure you can, but I don't have that machine any longer, would probably not get it to a good state, and would waste even more of my time.
It wasn't a simple plastic crack. The drawer was comprised of 3 bins (on the same part), 2 of them covered by rubbery lids. The rubber needs to seal the bin below, otherwise detergent and softener leak and make a mess (which was happening at this point). One of the bin walls somehow got completely deformed. The rubbery lid wouldn't seal, and to make it worse, it eventually split at the seal because of the pressure from the bin wall. It would have been a nightmare to repair to an acceptable state.
Also note that the bin lid is something that needs to be opened and closed frequently for top-ups and cleaning. No home repair would survive for long.
Better yet would be never needing an update, but alas.
Uhm every tech bro does this it is what makes the tech industry a fucking Bond villain lol.
> If he can demonstrate someone remotely jailbreaking your TV, or flipping on those settings without you knowing or doing anything to your TV, that would be a far more damning issue, in my view.
There are ways to remotely jailbreak LG webOS TVs without user interaction, using the same (or similar) vulnerabilities you use to root your own TV voluntarily.
The main reason tools like https://rootmy.tv are prefixed with disclaimers and require user interaction is because we're being courteous, not because they're technically necessary. (source: I own the rootmy.tv domain)
The security posture of webOS is absolutely terrible, at least, it is in the way LG deploys it.
But vulnerabilities that can be remotely exploited without user interaction (CVSS grade 9-10)?
Holy shit. RF to zero-click exploit is a new one. I guess digital-everything wasn't always a good idea, this probably wouldn't ever have been a problem with analogue antennas and CRTs.
What are the people at LG even doing?
As an aside, I once interviewed one of the guys who wrote Teletext processors for analog TVs. He was a very interesting individual.
So no responsible disclosure, I see.
Not knowing any more details, it still sounds like you'd still need the user to tune to the actual frequency on the correct receiver (to cause some buffer overflow?). But then still there's no internet to do anything. So you'd need some very specific f/up exploit to then change local settings on the device I imagine.
Either way, would be a great opportunity to demonstrate this in a video, now that there's attention on the topic, to further amplify the pressure on LG's "terrible security posture" as you say.
Huh?
I read this as "Wait until the model is EOL, hoping it won't be disclosed and fixed until then and also not fixed afterwards"
Is this not what you meant to say?
If manufacturers had a sanctioned way for the user to get root access to their own hardware, responsible disclosure would've made sense, but as it is, vulnerabilities are a useful tool for the owner of the device.
While some stuff are legit issues such as ADR, people now think they are wire-tapping. Because somebody used a rooted device to show-case recording silently through their device.
Can you blame corporations having this control-freak nature when shit like this happens?
It's stuff like this that likely pushes corporations now to invest more into device security, and locking down their stuff more.
Good for security and the corporation.
Maybe mid-term good for you consumer, because they might get more cautious with tracking stuff.
But long-term bad for you consumer, too, because they will make sure to lock down their devices better.
But that's not going to happen.
(And yeah, as pointed out by another comment, if you officially allow users full control of their devices, you are less likely to have people sitting on undisclosed exploits so that they can get it without your help, and as a bonus you have an easier argument for why you are not liable for what someone does with that control)
> Can you blame corporations having this control-freak nature when shit like this happens?
Is "shit like this" referring to the corporation spying on the user, or the user discovering it? Because one happened before the other, and so impossibly could have caused the former.
> It's stuff like this that likely pushes corporations now to invest more into device security, and locking down their stuff more.
Or they could just sell the device users want, and not sell their users.
The video draws exactly that picture, a nefarious actor, remotely taking control over my TV and recording Audio from it
On a different note: Are you, in any way, affiliated with LG? You read to me as someone who is "unhappy" with the findings.
The attack-surface only gets lower when the TV is no longer in use and is disposed. That doesn't happen at EOL, customers don't suddenly throw away their TVs after 2 years.
I'm happy with the findings and hope that it gains momentum, but unhappy with the dilution of the matter with speculation, assumptions and sensationalism, because it allows the vendor to wiggle out of it and wait for attention to wind down.
I would prefer a clear spotlight to be shined on #1 the ad-networks business model of TV-manufacturers and #2 the security of their (very powerful) products.
If the process results in regulation which also requires the TV manufacturer to offer root-access to the consumer to verify and control its operations, I would be overjoyed.
But this is unfortunately not a subject of the current narrative at all, it will actually result in the opposite (more effort to lock-down the OS to prevent future sensationalism reporting)
It is certainly not work that I would do to benefit a many-billion dollar company, for ~free. I may do it to benefit device owners such as myself, instead.
LG is solely responsible for the security of the products that they choose to sell.
If I, a corporation, declare that I only accept security reports carved on clay tablets in ancient greek and hand-delivered to my office in Timbuktu during a total solar eclipse - does that stop responsible security researchers from disclosing their findings publicly?
Of course not.
If the guy sends a clear message to the best public contact address he can find with 15 minutes of searching; and gives them 30 days to patch before publicly disclosing the bug; then he's performed responsible disclosure.
The vendor's corporate policies and release cycles and contact addresses and triage procedures are their problem.
If the manufacturers responsibly included a responsible way to install custom software/firmware, perhaps people would feel more inclined to help them. Their current attitude buys them very little goodwill.
It doesn't even matter what exploits are publicly known and closed at any given moment. What we know is that at every given moment, no matter what security hole was just found and closed right now in some device, always later it turns out there were others not yet known by you but known and used by someone. This has been everything with an OS for 40 years. So yes, of course, right now, on every tv, and everything else, from any manufacturer, there are "grade 9-10" exploits just sitting there. It's the default state not some exception.
I presume LG is like most vendors and stops issuing updates for older models after a while. It's pretty hard to keep software up to date when the vendor stops issuing updates.
I think it’s quite reasonable with this framing to question frequent update cycles.
It’s likely you understand this well and have decided to argue something else for reasons unknown.
The video is quite a mixed set of topics mangled together, which is a pity because IMO a cleaner separation would be more beneficial to get the point across.
They should have decided to set the focus on a specific area and then present every finding around that, i.e.:
1. The Ad data-collecting platform TV-manufacturers are operating, what data they collect and how they use it.
2. The vulnerabilities of the OS in a SmartTV, and the potential issues to exploit them for malicious purposes.
3. The general behavior of the device when connected to your network, with features like voice control, App control, Smart Home etc. enabled, and how it may expose information about yourself.
All the points and scenarios in the video might be valid, but they jump between those scopes and imply that its all the same, weakening the whole investigation.
If I'm LG and forced to respond to this, I can easily focus on dissecting the voice-input topic as a mere demonstration of the feature and how rooting the TV beforehand just showed the local process of handling it, steering the narrative away from the (IMO) much more important topics...
It's unfortunate, because they're one of the few voices speaking out about issues like this.
Sending to LG a JSON with a list of all the devices in the current broadcast domain is NOT "normal local device discovery behaviors" and everyone should be irate about it. Stop normalizing capitalism surveillance.
Wow. Please stop spreading things like this.
Not having root means not owning a device you paid for and have in your home.
Of course root allows you to tinker with your device and make it run what you want, but:
- Rooted devices make devices unpredictable. As shown in the video: How do you trust that your hotel/AirBnB is not using root on _their_ TV to use its microphone to spy on you? Or actually records your video output (instead of "just" ACRing it)?
- Re-selling: How do you know that TV you bought is untampered? How do you know it does not have software with malware installed that steals your credentials?
But in this case… I don’t know. The OEM is so actively hostile you might be better off just taking the risk with root if you must purchase it at all (and physically removing the radio/microphone hardware not being an option).
Many rooted devices display during boot a warning that they have been rooted. This is a problem that has been solved for more than a decade, but manufacturers pretend not to know the solution, because they are actively hostile to user freedom.
> How do you trust that your hotel/AirBnB is not using root on _their_ TV to use its microphone to spy on you? Or actually records your video output (instead of "just" ACRing it)?
Let's pretend there aren't plenty other ways they could spy on you. If it's bad if a hotel does it, why is it okay if LG does it? Do you honestly trust LG, and the thousands of "partners" that they sell your data to, and every government whose warrants they have to honor?
Your argument reduces to "if the warden lets us out of our jail cells, who will make sure we behave?"
Usually, this happens after a bootloader unlock because then verified boot is disabled. You can still have a rooted device and not break verified, resulting in no warning. See: jailbroken iPhones.
I wouldn't say it's a solved problem. Just have to find an exploit that works with verified / attested boot.
And device manufactures are getting more and more restrictive here, too. Why do you think that is?
> Let's pretend there aren't plenty other ways they could spy on you.
Sure, of course there are other ways to spy on people. But as we see here: If the device itself does it, then we like to blame LG. If they used an exploit to do that, then we blame LG's shitty security.
If a hotel owner installed a microphone inside one or their specific TVs, then we blame the hotel owner at least - not LG.
> If it's bad if a hotel does it, why is it okay if LG does it?
It doesn't seem like it is okay. We are discussing this right here.
> Do you honestly trust LG, and the thousands of "partners" that they sell your data to, and every government whose warrants they have to honor?
Do I trust LG more than a shady hotel / BnB owner or eBay seller? Yes. Do I trust them fully? No. It's not fully binary, I'd say.
> Your argument reduces to "if the warden lets us out of our jail cells, who will make sure we behave?"
I am just trying to say, it's really not that binary. You can extend that to other places whenever attestation is involved.
Do I like Linux and open platforms? Sure! Tampering is fun! Do I hate people using open platforms to scrape my websites and constantly cause load, steal my content and use that for AI training? Also, yes.
But how can I fight that? We run into CAPTCHAs, Cloudflare, Anubis and co. Now that issue is reduced, but the openness is also gone.
And you always see in tech spaces we rather want "dumb" devices rather than smart devices, because we cannot trust them.
Attestation buys you more trust, but at the cost of openness.
In general though on devices that are rootable, white-hat hackers are more inclined to responsibly disclose vulnerabilities instead of releasing them as a way to root said device. So having a rootable phone does increase security.
What doesn't increase security is when bank apps that are essential to daily life start detecting that a device has been rooted and force a lot of people into using closed source extensions to hide the fact that the devices is rooted.
> What doesn't increase security is when bank apps that are essential to daily life start detecting that a device has been rooted and force a lot of people into using closed source extensions to hide the fact that the devices is rooted.
I'll ask naively: Why not? I can come up with a bunch of arguments why it does help the bank and why it might reduce the risk of certain attacks.
If it’s a problem, unplug it.
If it’s a problem, don’t buy it.
Works for everything!
you/we/me not having root while, for example, Google Play Services does on invalidates everything you said.
Compared to, say, random Magisk modules or some random crap the OEM developed?
The inevitable outcome of this video is that TV vendors are pushed to harden the security and preserve the trust-chain, because part of the (valid) claim is that nefarious actors may break the security to use the device for spying on you.
With support from an actual journalist, it could be reframed to also emphasize the importance of controlled root-access to monitor and control the devices behavior.
But none of this was done unfortunately, and if I'm LG I don't want to see another video where someone reframes user-initiated voice-input for a web-search as spying initiative by showing some device-logs of the transcription process in parallel...
Like every single Microsoft laptop out there does so? Think a bit harder before sentences like this, please.
Did you read and comprehend the rest of my statement?
I'm trying one more time. I'm not arguing against you, maybe read this again in a few hours:
I believe you want to have full control over the device you own (like I do btw).
For this you need to acknowledge that right now it is not in the interest of any party to provide that, because it requires additional effort, carries additional risks and doesn't create an economical benefit.
You have to MAKE it the interest of ANY party in the chain (the manufacturer, the seller, the consumer, the lawmaker,...).
Being an angry consumer is not getting you there, asking people to "vote with your wallet" is not getting you there.
--> Why? Because you won't reach a critical-mass of consumers to move the needle for the manufacturer to notice and take action.
Creating noise on security issues and potential hacking won't get you there.
--> Why? Because IF it creates ANY reaction, the public reaction will be to hold device-manufacturers responsible, which (if it works!) will cause them to just spend more effort to lock down their products even more, secure the trust-chain in the OS and simply stop operation when it is broken at any point.
Trying a mix of topics by mangling everything together, to create as much noise as possible? It will not get you there.
--> Why? Because even if that noise is creating a critical-mass, if it's not based on a sober solid foundation with a clear demand, it is not actionable and will die down. Everyone knows that this will happen and affected parties will count on that.
So. What GETS you there is "artificially" making it the interest of the involved parties, STEERING the manufacturer into the desired direction.
How do you steer things if the sheer economics don't do it?
(I don't know your experience, so YMMV from here)
From my experience, the only sustainable way to achieve this is that you literally regulate it, by demanding a LEGAL requirement.
e.g. Pushing for regulation to provide the user full control over the product if he wants it, acknowledging that the process reduces the responsibilities of the manufacturer for that device.
You do that by finding as many reasons, as much evidence as possible that this is a solid direction: Security concerns, environmental concerns/waste elimination, "ensuring a free market",...
--
So how do I know that?
Because I LIVED through it already (with many other active people in the scene), trying to make bootloader-unlock and community OS a default thing on Android Smartphones.
We amplified the topic when the industry was still new and growing, created more noise than there actually was, riled up journalists to act like this is a crucial buying decision for the market, lobbied the whole industry, to a point that they actually made it a competitive feature.
Doing all that against a juggernaut of interests AGAINST it (in US e.g. Verizon, which never bulged, vendors with concerns about unjustified warranty-claims, journalists/users stating that this is weakening security, etc.)
And what happened? It all died down because we didn't use the momentum to get it into a regulation when there was the chance. Some fruit-company demonstrated over years time and again that this doesn't matter, then even turned it into a marketing-feature to NOT give full control to the user.
Meanwhile the momentum and interest in the market died down, and for the past years we started to lose bootloader-unlock again in many brands, without any notable impact on their sales.
So if we have to do it again, in a matured market (like TV is), how do we do it now?
Again, YMMV, but for me, having lived through that already, the only viable way is regulation.
Regulation which demands a solid trust-chain in control of the vendor, AND the possibility for the user to unlock it to take control over the device.
Anyway. Peace.
If you don't have root rights, you don't really own it. All other arguments are talking past this key point.
Otherwise, they start a voice command service (clearly displayed on the screen) and then say your TV is recording on your conversation. Like duh, of course my TV starts recording voice when I use voice commands.
And of course you have to trust LG with their TV and (not) having access. That same logic applies to every different company.
Do you actually want a channel with 2.66 million subscribers to show how to get remote access to TVs used by millions of people? :-P
The influencer economy is a bit soaked these days. You need to crank up the stakes to keep the viewer's attention.
Yeah no this is just incorrect. There's many cases where jailbreaking actually fixes issues when a vendor abandons the platform. It also enables usefulness for a product long after it's been EOL'd.
The main thing I'm taking away from this LG thing is that I'm going to root my TV as quickly as I can with whatever CFW will get rid of this surveillance capitalism atrocity attached to the wall in my family room.
That does not mean that LG does all that by default.
> If you root or jailbreak your devices, you've, by their very nature, broken their security. If he can demonstrate someone remotely jailbreaking your TV, or flipping on those settings without you knowing or doing anything to your TV, that would be a far more damning issue, in my view.
What is this authors point?
LG doesn’t need a root exploit to get this info because they made the fucking thing.
I read the article and then grepped for “Texas” to see if I missed it. The author never mentions the fact that this data collection was only found out initially because of a Texas government lawsuit that LG settled on by agreeing to give “informed consent” to users about data collection and then the warnings started popping up in unexpected places.
Is the author arguing that jailbreaking your device to find out what the manufacturer can do to gather data on you is dangerous because I don’t know, questioning your corporate overlords is bad or something?
This is the major issue with this video: It mixes stuff done by LG (ACR) with stuff done via rooting (audio recording). And now people think LG is 24/7 recording your conversations and uploading them somewhere. This has not been proven.
That nuance is important if you value good journalism.
Otherwise if we're just our here throwing random allegations because "corp bad", might as well say LG 's TVs are turning the frickin' frogs gay.
Sorry but such contrary takes in the face of this sort of evidence are either contrary for the sake of it or paid astroturfing.
However, just because your TV does ACR, does not immediately mean they listen 24/7 through your TV through any conversations even if the TV is off.
That is another, also quite different level of claim.
Spend some time building your reputation before arguing for divisive topics or be ignored.
Consider it a mechanical Turk but for social trust.
You have to start somewhere. Better makes sense to start looking at the arguments rather than the author.
It also helps you train your brain. Stop trusting someone solely because of who they are.
You can comment about anything here and build credibility.
Just don’t start on the most divisive topics.
* When disagreeing, please reply to the argument instead of calling names.
* Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.
* Please don't post shallow dismissals
* Please don't post insinuations about astroturfing, shilling, brigading, foreign agents, and the like. It degrades discussion and is usually mistaken.
And yet not once does it mention "don't start commenting on divisive topics"
You can follow them if you want, but I find it hopelessly naive to trust brand new accounts whose first topics they comment on are touchy ones.
And to be clear, I'm not defending LG here. Their terms and conditions are terrible, 'We know who's in the LG household… we own the glass' is not something that should be said by any appliance company and shows a clear lack of ethics. But if someone is going to make a video explaining what's happening it's better to stick to what LG is actually doing instead of listing potential issues without making it clear.
A rooted tv by definition has less security, if you show that you can record because you have full control over the device that only shows that there's no hardware block for the mic (which most devices in existence don't have, apple, Framework, pinephones are the exception there). It's not in anyway different from most phones and devices that people use in daily life.
Intercept what a normal tv does, show it uploading your voice recordings, your local network device names, etc.
Don’t bury it under conspiracy theory. Had this contained what actually went on I suspect it would be treated far more seriously. But then the video would be shorter and fewer ad views for the “influencer”.
216M Spy TVs – The LG Smart TV Problem [video]
GamersNexus did an investigation which may overstate the privacy threat posed by LG smart TVs.
If they had shown what a normal LG collects that would be fine.
If they rooted it to install a new root certificate so they can MITM traffic and see what’s actually been sent that would be interesting.
From what I read it’s “you can use a Turing complete computer with network and microphone access to do things”. I mean sure.
What I want to know is what does it actually do
I would love smart TVs to have a “no smart functions” option, and I know that they don’t because that’s part of the ad tech economy so beloved by HN.
What I want to see is what does it actually do and perhaps how can it be blocked technically.
Maybe it’s in the video, but videos are terrible ways to communicate this, and it seems to be mainly breathless nonsense and possibilities.
Would the router's firewall protect it if it denies incoming connections?
They literally write "Now, I’m not going to claim to be a network expert. I may be totally off-base, but what? Reverse DNS? I don't know what this means."
The findings are a smoking gun already.
The bar shouldn't be a video of an NSA agent or someone from LG listening your everyday life. I don't doubt this happens but we shouldn't expect gamernexus to be able to prove it.
Jesus some people with their whataboutism and nihilism.
Maintaining enemy lists like the one of Drew linked there has been illegal in Germany since 2021 as part of the government's (very necessary!) efforts against hate crimes and right-wing extremism.
Or at least that's my understanding of the law there. Maybe it's exempt based on technicalities.
In any case, I can in many cases emotionally relate to why he is doing that, but.. oof.
I always say any serious computer needs blinkenlights and a smart TV has literally millions of them.
