Suspected Freezer Hacks Disrupt Supermarkets in Belgium and Sweden

Supermarkets in Belgium and Sweden reported sudden changes in fridge and freezer temperatures on Monday, November 2. Bloomberg Technology described the incidents as a suspected cyberattack, drawing comparisons with recent attacks in France.

Several Delhaize store managers received an overnight message from the chain about refrigeration temperatures, according to RTBF. Its report said several dozen supermarkets in Belgium and Sweden were affected.

The overnight warning was followed by reports on November 2 of problems extending beyond one supermarket chain. nu.nl named Delhaize, Spar, Carrefour and butcher De Laet & Van Haver among businesses reporting altered cooling temperatures.

Store managers said they were unable to control freezer temperatures while hot air flooded refrigeration units, according to Top World News- News18.com. That account describes a loss of control over equipment needed to keep food cold.

The disruption led to food being discarded. Euronews reported that 40 Belgian supermarket stores were hit and that €100,000 worth of food had been thrown away.

The reported geographical reach also widened. Alongside Belgium and Sweden, nu.nl included Luxembourg in its account of hacked supermarket refrigerators and freezers.

The coverage differs on both certainty and financial scale. Bloomberg Technology called this a suspected hack, while ABC described a cyberattack causing losses running into millions across dozens of supermarkets in Belgium and Sweden.

That broader loss claim cannot be reconciled with the €100,000 food-disposal figure reported by Euronews from the supplied coverage alone. The reports do not establish a final total or explain whether the figures cover the same stores and losses.

The central questions are whether the temperature changes share a confirmed cause, how many stores were affected and whether refrigeration control has been restored. The supplied reports do not identify an attacker or establish how the systems were accessed.

A connection to the earlier French incidents also remains unconfirmed. Bloomberg Technology reported fears of a similar attack, rather than an established link.
