The magic question is: why isn’t this fixed yet? And then the specifics, the nitty grift of why not. Thousands of industrial fridges. They presumably all need new hardware, or at least tenporarily all need a RPi with additional software on the network cable, or it could even worse… are they on regular company wifi? Don’t these companies have VLANs? It’s astonishing that this is what brings billion dollar companies in a key supply chain down.
This little gimmick cost Ahold in the Netherlands an estimated 300 M€ a few weeks back. Enough money for any firm to set the engineers to work? Where they waiting it out? Having read some more… another part of Ahold (the Belgian part) was hit and has (only now…) taken all fridges down from the internet. What is IT risk doing in a firm like that? Internet of Shit is a decade old. I am not amazed non tech sectors are perhaps a bit slower in IT risk management. I am amazed that an ongoing attack situation can still cause trouble 4 months after publication and months after board level headline grabbing numbers are widely publicized.
Me and my crew (yet to form ;) will visit any fridge for a measly 100 K€ a pop to take them offline. Book early, because once the script kiddies hit, we are on the road.
The way some of these publicly listed companies work now they would "rather have" a cyber incident and claim the damages on insurance than hire engineers, because that looks worse on a quarterly report to have salaried workers.
