Man discovers his parents' coffee machine used 1TB of data in 10 days(www.dexerto.com)

In the Twitter thread linked, the person confirms two things:

1. It saturated the local network with 1TB of metadata sniffing scans, not the network uplink to the outside world.

2. It does so because, as Keurig notes, it’s collecting data about your household in order to let Keurig sell it to advertisers.

That's obviously bad and I hate it, but how much value even is there is the data that a spyware coffee machine could collect about your home? What advertisers would buy such data and what would they advertise to me? What is the marginal value of that data?

Knowing what TV you own, what phone models are used in your house, and what other devices you own tells advertisers about your spending patterns and income.

And can be used to cross-correlate with other datasets to further narrow down who you are and how you can be targetted.

I love that a poor, stupid man like me is being targeted by teams of the smartest data analytics professionals on the planet.

Makes me think of DraftKings. You take your average 20 something sports fan - drinking beer, watching the game. And, on the other end of that smartphone display exist some of the most complex algorithms ever designed by teams of mathematics / statistics PhDs and it's deliberately built around targeting... this one guy from Florida who is pretty sure his team will be up by 7 at halftime.

Maybe it's more of a morbid joke, but it makes me laugh to think about.

I wonder if you can identify the age of devices based just on network scans? Like if an advertiser can tell I've got a washing machine model that was last sold 7 years ago, it's time to spam me with washing machine ads.
bityard 7 minutes ago||
Quite probably. nmap does (or certainly used to) have options to report the OS of a given machine had based on various quirks of the packets it got back from them. It was disturbingly accurate at times. You put that together with banner messages from running services, MAC addresses, responses to broadcast packets, deliberate probing, and the number of devices you _can't_ remotely identify on a network without actually logging into them is probably very small.
paimapi 38 minutes ago||||
You can also map a home out depending on signal strength. That gives you approximate size of home which gives you approximate income.

It can also correlate it with geolocation data. Google, for eg, sniffs all broadcasted SSIDs with their StreetView cars. If you can pick up on a SSID (or any of the MAC addresses of the other devices), you can buy the data set that includes it which further pinpoints demographics given the neighborhood AMI.

You can also build behavioral profiles patterns based on things like, for eg, if a baby monitor model is present or a robot vacuum, if certain devices only connect at certain times, etc.

I think the general rule for adtech is that profile guesstimates just need to be around 70%+ fidelity to determine if a sale can be made.

Lastly, you can also just sell the data on the gray market. The more datapoints, the higher the price. Most consumer product companies do that since we have little-to-no data privacy laws and the people who seem the most aware of it also are generally very apathetic and disinterested in advocating for them.

dovin 17 minutes ago||
Yeah, it definitely makes sense to me if what adtech is often doing is just backing out from specific data to a general profile like income, location, etc, so that that level of targeting can work.

I don’t dispute the purpose of the data collection, but I can’t believe this quantity of data collection is intentional.

There’s no way Keurig is has the intention of paying the kind of costs required to collect a terabyte of data every two weeks for millions of people who own their coffee makers.

There must be some kind of bug here. I imagine if you unplugged it and plugged it in again the data usage would settle down.

As article says, the coffee machine didn't 'collect' or phone home a TB of data. It just saturated the local network looking for data to collect.

Oh let's be charitable! A parameter measured in ms is mistakenly thought be measured in s. Hilarity ensues.

Real world example: þe Windows registry DWORD time periods seems to invite 10^-3s granularity for totally inappropriate timescales. Perhaps its considered a "best practice" by the dick heads that decide to do these things, who knows? Why bother considering how a sysadmin might actually want to use the knobs and dials and what is an appropriate value for a parameter.

I could probably find a better example but this is recent: Smoothwall has an agent (IDEX) that you install on a Windows domain controller and one of its functions can be to harvest DHCP data and pass it onto the firewall so that it can track sessions. The upload period is a registry DWORD value.

I fixed a "problem" by stopping IDEX trying to upload data a thousand times per second. I will also point out that switching on this functionality and the periodicity setting is only applied by editing the registry - there is no GUI for this. The dReal world example -ocs are clear that you should initially set 1000 as the period.

For me that sort of thing comes under the heading of "you are holding it wrong", potential victim shaming and rubbish engineering.

If there's one thing you can be absolutely certain of it's that every scrap of the data they collect is either making companies money hand over fist or they strongly believe that it will soon. No company is going to bother collecting, storing, (hopefully securing), backing up, and analyzing all this data without a reason, and to them money and power are the only reasons that matter.

Right now companies are somewhat limited in how much use they can get out their horde of private and personal information, but AI is changing that rapidly. As long as you don't mind a huge rate of error (and companies don't because it all becomes "good enough" at a large enough scale) it's basically perfect for the task of digging through endless amounts of information and spewing out bullet points.

I was thinking that repeated small probes add up quicker than you'd expect. But this is ~1.1MB/sec, which still seems a few orders of magnitude off.

Now I'm left wondering what this traffic actually is - assuming probe (arp/icmp) packet size of 64 byte, that's 17kpps. I don't think an ESP32 class Internet-of-Trash chip can even do that. Even bulk transfers rather than small probes would be pushing it.

Perhaps this thing found some fellow-traveler device streaming video on a port it happened to connected to?

... the linked xit says it "broadcast 1TB of data". So maybe some protocol with a much larger packet than icmp, spammed in a hard loop without any delay?

Tongue-in-cheek, but my Moccamaster which I bought second-hand is still doing great after 15 years. Two deep cleaning sessions in all that time and just running it with vinegar a couple of times a year seems to be all it needs.

The device is dead simple. No advanced electronics. Nothing complex that can break. Just a coffee maker fine-tuned to near perfection.

The only flaw it has is the handle for the pot. I've resorted to replacing the plastic handle with a fancy walnut one I made myself. I needed that because we tilt the pot sideways to fill the reservoir with water (because of the placement on the kitchen counter and the cabinets above), and that plastic handle is not designed for sideways stresses.

You shouldn’t fill the reservoir with the coffee pot, unless you’re really washing the pot super clean after each use. Better get a proper jug for filling the reservoir, so you’re not putting coffee residue and oils back into the clean-water system.

ButlerianJihad 42 minutes ago|||
You have latched on to an important idea here.

Since most appliances now contain a general-purpose computer, it would be unfair to say that a device is incapable of hacking or hosting malware, because any device with the given sensors and radios and capabilities can be essentially reprogrammed at any time.

So, if we're looking at smart TVs with cameras and microphones and Wi-Fi and Bluetooth and all the connectors, or if we're simply looking at a an ordinary network device, they all fall under the umbrella of general purpose computer, and there is no way to trust their maker, or some equally capable programmer, not to turn them malevolent in some future update.

I don't view this as an issue of terms of service or of software or of your manufacturer. I view this as an existential and fundamental problem with dropping general purpose computers into your home and behind your DMZ.

Consumer operating systems like Windows and Apple have all kinds of countermeasures against this malicious use. But without the proper introspection and without the proper safeguards, a device that looks special purpose but is in fact general purpose is far more dangerous.

mindslight 17 minutes ago||
Getting technical - the way I see it, the problem arises from a combination of three things - sensors/access, Internet access, and source of software/authority.

Sensors/access is unavoidable, otherwise the device doesn't actually do anything useful. The point is it sets the scope for what the device is able to affect. When people say "set up a separate IoT VLAN" (that still has Internet access) this is basically what they're addressing - how a device can access other devices they may care about more.

Internet access is the catalyst that's created this whole dumpster fire - I don't care about the proprietary software on my keyboard/mouse/UPS/monitor/GPU/etc to nearly the same extent. I've got some TP-Link plugs that I control local network only. They don't get Internet access, so no updates, telemetry backhaul, etc.

The authority to update/configure/change that software is the crux. With proprietary software, there are no cuddly kittens period. Here we've got a case of a "legitimate" company choosing to be a bona fide attacker to increase their bottom line! The harm was exacerbated by a bug causing it to run amok, but even without the bug they are deliberately violating trust.

But even libre software can fall to security holes as well. Meaning you want to centralize the attack surface as much as possible, for administration's sake of keeping updated. "Internet" of things is basically the direct opposite of this - postulating many illegible fine-grained links between devices on different networks. Whereas really need more like the Home Assistant model, where peripheral devices may communicate over the network, but it's only ever over the local network. Think how ethernet is set up when used in industrial control networks (or at least how it should be set up, hehe).

It's not enough to simply have a IoT VLAN that you put all your IoT devices on. Because those devices can see one another. In this case, if the coffee machine can see what type of smart fridge and smart toaster you're using, they can sell that data.

I default to adding IoT devices to a 2.4g "Guest" network where they can't see each other. Exceptions are IoT devices that need to see their friends to do what I bought them for, or devices I want to integrate with HomeAssistant. In those cases I create a separate IoT device per IoT brand.
