Key Questions Answered
Hackers interfered with refrigeration controls at hundreds of stores, including Intermarché and Netto outlets, by heating units to 50°C for six hours overnight and forcing retailers to discard spoiled food. ANSSI identified the vulnerability in software made by Danish company Danfoss.
Cybercriminals typically search the internet for exposed equipment using factory-set passwords, unpatched software flaws, or control panels accessible from the public internet. Once inside, they can alter settings, collect information, or use the device as part of a hijacked network.
Owners can protect their connected homes by changing default passwords, enabling multi-factor authentication, and installing firmware updates promptly. Additional measures include disabling unnecessary remote access, limiting connected devices, and isolating smart appliances on a separate guest network.
