It must be crowded on these devices by now - it may be a bit misleading to think of it as a single botnet when there are multiple unrelated entities controlling the same devices via the same methods.
Like seriously, many of them are sold for stupid cheap prices like $5/ea. Or advertise unlimited movies/shows/etc for similarly unbelievable prices.
Putting aside the copyright infringement aspect of it, to me it's extremely obvious "wait... _why_ am I paying so little here?".
No, it's not because movies and shows are 99.9999% profit (spoiler: they aren't), it's because you're _paying_ to install a backdoor that will rip and tear everything on your network it can.
You like having a credit card? That's precious, it's mine now.
Look at me, I'm the network now.
I mean, maybe. More likely imo you're paying for the absolute cheapest hardware and fastest never-updated software someone could throw together and make _any_ profit on. Someone probably had 100k shitty little chips sitting in a warehouse and this was a way to do something with them.
The outcome is really the same, it's just the steps to get there are more human nature.

How is this different from buying hardware and software from big market players?
Why it's not obvious to every Senator and Representative in our Government is frustrating to an extreme.
We really do need to end our enhance our trade protections one way or another.
Why? How does this impact your life enough to be that frustrating?
I mean, it's pretty obvious the services are paid piracy. But it's got to cost something to pull VOD movies from wherever and serve them with an http server limited at 8 mbps even for content that exceeds that. Obviously someone doesn't want the content they stole to be easy to steal... too bad you can't reasonably play it either. :P
Fucking everyone is spying. I started downloading and decrypting apps from the App Store. It’s a god damn nightmare. Random apps are storing keys in the keychain (thanks expo!) that never leave our apple account. They follow us forever. You can’t delete them. Well.. there’s one way but it involves backing up your phone, putting it in recovery mode, and restoring from backup.
You can look around for something like device isolation, but I doubt you'll find it unless you go a couple of steps up from whatever router ISPs ~give away these days.
you can however isolate with vlans and a vlan capable switch, then it would be on the router to isolate traffic between lans (I do exactly this for my less trusted virtual machines)
Some (even cheap) unmanaged switches have a "vlan" or "isolation" switch that does exactly that, where only one or two "uplink" or "wan" ports can talk to the rest. If you have a managed switch, vlans is what most people would use for isolation.
On the software side you could also assign /32 IPv4 addresses only and add explicit ip route for the router only.
Wired clients are unaffected.
Oh no, let me get my tiny violin! Really hard to feel bad here. For most home users (that don’t expose anything sensitive on their LAN) these boxes are not a threat, seem to be doing a useful service in providing a superior streaming service that the balkanized official ones, and also shits on internet spammers/advertisers and frees up loginwalled content - sounds like a pretty good box really.
Also, is there a better word than ad fraud? It needs an innocuous sounding euphemism like pretty much everything else involving that industry has. “Monetizing ad display”? “User-agent driven conversions?”
You can buy a better one that does not have malware installed. So these are complete and total garbage and no sane person should run them under any circumstance. Sounds like you have a bias which has prevented you from thinking about this clearly.
You can buy a better one if you have the technical know-how. But if you did you'd probably be running the *arr stack anyway and not need such a box. But these boxes do work and aren't any more of a threat than your usual public Wi-Fi for the casual user who does not expose any services to the LAN.
The alarm around them is less about the threat to its owner and more about the threat to the tech ecosystem at large... which considering how hostile it is to users, shouldn't really be something they have any reason to worry about.
I'm confused. I intentionally use ADB over the network sometimes, and I have to explicitly interactively allow each adb client by its key. Are they shipping boxes with adb configured to just allow any connection without any verification?
Just don't run code you download from the internet or put your passwords to important accounts into cheap devices and you'll be fine. Normally people don't the the former, but sometimes do the latter.
edit: To be clear: the bitterness in this comment comes from how many developers assume loopback is secure. However, most website are allowed to send requests to local ports on your computer (IIRC) so that assumption is basically completely false. This is forgivable, except in a world where every developer runs tons of extensions/scripts/open-source apps, and have next-to-zero blast-radius-reduction methods, it makes me sad.
Maybe I've just gotten lucky?
(i will say putting a device not running open source software/firmware or something very locked down like a phone on your LAN is insanity, i could never)
When you run VS Code, it spins up a local language server that is capable of making code changes. That is how refactoring python works in many editors (including VS Code).
A website that you're browsing could potentially send requests to this server asking for code to be inserted that fully compromises your device. What keeps us safe?
- maybe the website is only allowed to send GET requests, not PUT requests, and maybe the language servers that you're using are all "hardened" so that they will never permit mutations via any get requests, and never have a misconfigured CORS header
- the website has to guess the correct port and the correct language server with a known vulnerability
- any website doing this on a large scale would likely get the language server patched and the website on a block list
- there might be other safeguards that I'm not familiar with. For example, I believe that Chrome disallows this by default
So now, here's my frustration: these two statements seem hugely at odds with each other:
> I'm ok getting pwned every few decades if the tradeoff is never worrying about this shit.
> (i will say putting a device not running open source software/firmware or something very locked down like a phone on your LAN is insanity, i could never)
I'm ok with a person who makes either statement. I'm also ok with a person who makes the first statement, and also wants their LAN locked down. However, I do not feel as though the a LAN ever needs to be locked down unless a person in running a server on the LAN network. Personal devices (like laptops and phones) are plenty capable of resisting malicious networks by default (coffee shops, university wifi, etc). What else is on a LAN?
> mind virus it's the paranoia all security people get
I generally agree with you, but I feel as though I am the one who has accepted that personal laptops need to handle malicious networks, and I'm generally comfortable with that. I don't worry too much about putting IoT devices on the same network as my personal laptop, nor about connecting to coffee shop wifis.
Every time I ask this question nobody is able to give me a solid answer :/
> I know this may seem trivial for many here but how can regular people easily check and debug their network for stuff like this?
"Stuff like this" is very vague.
- If there is a device on your network that is occasionally sending requests to the internet, then it generally isn't hurting you. That's why security is weak here, because the person buying the device is not harmed.
- If you're worried about the device sniffing your local network, then "normal people" are typically safe. Computers that you use are typically safe from malicious devices on the network, and you're in no more danger than working at a coffee shop, hotel, or university network.
- If you're knowledgeable enough to be a danger to yourself, and need the local network to be safe to protect yourself, then there is definitely a longer conversation to be had.
Responding point by point (before I realized that you were asking for yourself, and not the average person):
> Regular people download shit all the time though?
This is fair, though on macOS, most people download apps from the App Store (macOS makes it difficult to run apps downloaded from the internet and not signed by a registered developer).
> Especially now with GPT, everyone is a programmer pasting code into command line.
I am trying to reference a group of "regular people" who definitely do not fit this description---something like "the average citizen in the developed world". My parents definitely are not writing code with AI and pasting it into the command line. Although this was not crystal clear in this comment chain.
> And how many people have IoT devices that they have to connect to WiFi? That’s total blind trust.
My point was these devices do not endanger things that regular people care about. Their computers are still just as secure as when they visit a coffee shop or connect to their university wifi.
> Every time I ask this question nobody is able to give me a solid answer :/
for stuff like this?
https://blog.xlab.qianxin.com/kimwolf-botnet-en/#network-pro...
That article has a more technical lens. It focuses primarily on the size and detection evasion methods of Kimwolf, rather than some notable (and definitely not unique) method of spreading.
Without looking too deeply, I'm going to assume that this is a successful botnet because it managed to get into product supply lines at big box stores and in app store games, rather than some clever virus that is spreading across the world.
I hope someone will correct me if I am mistaken!

As for your assumption the OP talks about how it uses residential proxies to get into lans, I don’t think it is a supply chain attack.

Now that it's publicly known I guess it's possible that they will close the door post-infection to avoid detecton. And it won't detect any other devices it's spread further to.
If you have a cheapo Android-based TV box or stick like the ones mentioned, throw it out or reflash it with Armbian after forensics.
I'm sure there are HN readers out there who have one of these. They were very popular a couple of years back.
