And on episode 48,942 of “Don’t Put Things on the Internet for No Reason”:
which once again begs the question. why the fuck is your freezer connected to the internet
Really, this is worth just 5 minutes of research. This is not like the stupid Samsung fridge you keep in your home. In commercial settings you may have hundreds of refrigeration units to track and manage in order to keep food safe. And it’s quite plainly very efficient to do this with remote management software, and yes this can be deployed locally with a local server to manage everything but it can also be done over the internet to cloud services and that can be much more feasible for someone who is trying to run a grocery and isn’t a network engineer or experienced server administrator.
I know someone will just say come on, it’s not that hard. To which I say fine, but the question here was why would anyone ever do this. There is actually an answer.
Supermarkets allow their freezers to connect to the internet so that maintenance and monitoring can occur remotely.
Yeah. And VPN connections exist so maintenance and monitoring can take place without direct exposure. But alas…
Yeah, but you would think they would have gotten them off the Internet after the first time this happened, even if it means having to hire an extra person to keep an eye on them.
Nit: it doesn’t beg the question (a logical fallacy also known as tautology), it raises it.
But yeah, is it really that helpful to network something you only want to set one time?
Actually, “beg the question” is a linguistic fossil from a time when “beg” didn’t mean quite the same thing it does today.
You want to monitor and perhaps automatically fix temp fluctuations? Maybe these things are smart enough to report parts about to fail? 🤷🏼♂️ But in any case it would be child’s play to make these things bulletproof.
One example: Set the local firewall to block all WAN traffic, all ports, to the freezer group (VLAN) except where the origin packet is the monitoring IP. I suck at networking and could work this out in an afternoon. Give me a week and I’ll have a deployment script for all the local firewalls, tested and ready to push the button. And again, I suck.
You don’t need an Internet connection to have a control system keep temperature around a setpoint, though. That’s usually handled by a lower level circuit that will continue to operate in the case that the high level interface is not responding.
Observability is nice, but you don’t need to expose controls to do this, you could just have a Prometheus endpoint.
I suspect it’s because the manufacturer is trying to sell RaaS (refrigeration as a service) and to ensure they get their monthly dues, they “offer remote maintenance and monitoring” or something.
I suspect your suspicion is accurate. Scanning with BLE or a flipper shows the coolers at my local grocery also. It’s like the cars, they won’t secure it until someone makes it and even then they’ll secure it against their customers freedom, not hackers.
Exactly! It should have a single non-internet connected computer per supermarket controlling the temps.
once again begs the question
Nope. Just raises it.
Why the hell freezers able to heat up to 50°C and connected to internet?
The coils need to defrost, so they are able to heat up to do so. Typically this happens for a very short period of time. Bit if the defrost cycle stays on for an extended period of time then the whole thing heats up.

This is the oldest of four duplicate comments.
It’s almost as if the longer we don’t riot and push the corrupt officials off a cliff, consequences for their actions always seems to fall onto us. Huh… weird…
