A cyberattack targeting refrigeration systems in hundreds of French supermarkets caused large quantities of fresh and frozen food to spoil, forcing shops to throw away their stock.
According to a Luxembourg IT expert who spoke to RTL on condition of anonymity, the significance of such incidents extends far beyond the supermarkets directly affected.
The attack illustrates just how vulnerable technical installations can be in everyday life, especially those not typically seen as part of the core IT infrastructure.
When people think about IT security, they usually focus on computers and servers, the expert explains, but this incident shows that "embedded systems and connected devices are also at risk".
While France was hit this time, Luxembourg could just as easily have been targeted, the expert warns.
However, he cannot say for certain whether the specific vulnerabilities exploited in France also exist in Luxembourg, or whether similar systems here are better protected.
The first and most important step, he says, is to develop an awareness of the risks.
The expert notes that actors behind such cyberattacks are well-connected and skilled at identifying system weaknesses.
It often takes too long for organisations to adapt to new attack methods, he warns, with decision-making processes still frequently being too slow.
Given the current geopolitical climate, he expects that such attacks will only become more frequent in the future.
Drawing the right lessons from incidents like the one in France is crucial, the expert stresses.
Even companies that have not been directly affected should take the opportunity to analyse what happened and use the experience to review their own infrastructure.
He advises against waiting until a company becomes a victim itself, urging businesses instead to conduct proper risk assessments now, so they can minimise their exposure before a crisis strikes.
