\"Cyberattacks<\/p>\n

 <\/p>\n

Recent cyberattacks on supermarket refrigeration systems in France, Belgium and other European countries have brought a critical operational risk into focus. The attacks targeted the cooling itself, disrupting the conditions in which food was stored.<\/p>\n

They raise a question that matters to every store and kitchen, whether the cause is a cyberattack, a technical failure or a door left open: who keeps an eye on your refrigeration system?<\/p>\n

Andy integrates temperature monitoring from rmoni<\/a>,<\/strong> our sister company within CHR Group, to help teams detect deviations and coordinate their response.<\/p>\n

 <\/p>\n

What happened?<\/span><\/h2>\n

Attackers gained access to electronic controllers used to manage refrigeration installations. These controllers were directly accessible over the internet. Once inside, the attackers activated defrost mode, causing temperatures in refrigerated cabinets to rise.<\/p>\n

The equipment followed the instructions it received, even though those instructions put stored products at risk.<\/p>\n

 <\/p>\n

Why can an attack like this go unnoticed?<\/span><\/h2>\n

In some stores and kitchens, the refrigeration controller performs two functions: regulating the cooling and providing temperature information.<\/p>\n

If that controller is compromised, its readings or alarms may become unreliable. A similar dependency can arise during a technical failure: when cooling, temperature recording and alarms share the same controller, software or connection, a single incident can affect several functions at once.<\/p>\n

This can leave teams without reliable information about storage conditions, making it harder to assess affected products and reconstruct what happened.<\/p>\n

 <\/p>\n

What does independent temperature monitoring mean?<\/span><\/h2>\n

Independent monitoring measures temperature through a separate system, with its own sensors and communication path, without controlling the refrigeration installation.<\/p>\n

Andy works with rmoni sensors<\/a> to provide this additional layer of visibility.<\/strong><\/p>\n

The sensors measure temperatures using their own probes and communicate with a dedicated rmoni gateway through a separate Zigbee network.<\/p>\n
