Chains in Sweden, Belgium and Luxembourg say fridge temperatures rose overnight, similar to hack of French stores
Supermarket chains in Sweden, Belgium and Luxembourg have said the temperatures of their refrigerators and freezers in dozens of stores rose overnight, prompting fears of a cyber-attack similar to one that caused millions of euros of food losses in France.
Sweden’s Coop chain told the daily Aftonbladet on Monday that six of its stores had been affected, while ICA said it was “aware that a limited number of stores were affected by an incident overnight which impacted their refrigeration and freezer systems”.
The question isn’t so much, “Why were these on the internet?”, so much as, “Why were these not securely connected?”
At my last job, our AWS resources were firewalled off, only accepting connections from our internal VPN. To get on that, you had to be coming from the IP of an office or a DevOps team member’s home IP.
The local firewalls could have only allowed traffic to the freezer VLAN from the remote monitoring IP.
And that’s just two ideas off the top of my head. If my dumbass can do it, you don’t need a high level networking expert to fix this.
