Cyber-Sneaks Turn Up the Heat on Supermarket Freezers!

Imagine walking into a grocery store and noticing the frozen peas and popsicles are starting to sweat! That is almost what happened across Europe recently when sneaky digital troublemakers carried out a cyber-attack on store cooling systems.

Supermarkets in countries like Ireland, Sweden, and Belgium noticed something bizarre: their giant commercial freezers suddenly had their temperature settings turned way up. Instead of keeping food frosty cold, the connected thermostats were remotely instructed to warm up!

Modern grocery stores use smart hardware—fridges and freezers linked to computer networks so staff can adjust temperatures from anywhere. But if those digital locks aren't super tough, unauthorized intruders can sneak through the network and mess with the dials from miles away.
