Germany's top cybersecurity agency, the BSI, just flagged major security gaps in Danfoss industrial cooling systems after hackers hit supermarkets across Europe, causing tons of food to go to waste.
One recent attack in France also targeted Danfoss technology, showing how real the risk is for businesses that rely on these systems.
BSI urges disconnecting Danfoss cooling systems
BSI recommends companies protect their cooling setups by using a VPN or disconnecting them from the internet completely.
They are also urging IT teams to install any Danfoss updates, but admit these fixes are not enough yet.
The big takeaway? Do not let these control systems be accessible online: patches alone might not keep hackers out.
