But then the supplier is responsible, why would you ever put a fridge online if you are are tech noob. Someone told these people to put these fridges online, they didn't put an Ethernet cable in the back by themselves for the fun of it.

>The markets hit here in Sweden are all in rural communities with very low number of tech workers.

Hej! You are wrong, here in the middle of Stockholm got hit.

ICA Baronen on Odengatan is one of several stores in Sweden that have suffered a major hacker attack. On Monday, their freezers were cancelled at 50 degrees.

This is in Stockholm - https://maps.app.goo.gl/BwbDST4dPVkjcdgA8

So no lack of IT workers/tech workers... Nor is it very rural.

>They likely order their system from a supplier, that should have alerted them and helped them, but apparently did nothing.

The first thing to do when you get access to these as a hacker? You disable the alarms...!

Now, the supplier should have set them up correctly over VPN, good passwords, Zero Trust etc but these an OT/SCADA are usually just open to the internet due to the simplicity of use.

Some of them (Coop) got new equipment after what happened in France and where gonna upgrade them in two days.
