A shopkeeper may bolt his door at night and still be robbed through the wall.
On Sunday night, by French reports, attackers took over the fridge controls of French supermarkets. They set the fridges and freezers to defrost, a low trick to play on any grocer. French outlets, BleepingComputer reports, put the toll at 250 to 350 stores.
The controls, French reports say, were made by Danfoss, a Danish firm. Shops of Intermarché, Super U and Leclerc were affected, Help Net Security says. Carrefour Market and Monoprix stores were hit too, by one trade blogger’s account. The head of one chain called the attack unprecedented, and this paper will not quarrel with him. “It is unacceptable,” he said.
The Paris prosecutor has opened an investigation. How the brigands got in is not yet known, and this paper will not pretend otherwise. In early August, researchers reported flaws in Danfoss and Copeland controllers. Both makers have since released fixes. Whether those flaws were used here, nobody can yet say.
A researcher found 2752 Danfoss systems open to the internet on Monday. More than half, we note with some alarm, were in France.
Any shop whose cold room answers to the wires should ask its installer to shut that door. The ices are already lost. We are unamused.
