Possible cyberattacks have triggered rising temperatures in grocery store refrigeration systems across Sweden, Belgium and Luxembourg.

The head of ⁠Sweden’s national cybersecurity centre, John Billow, confirmed on Monday to the Reuters news agency that the centre ⁠is responding to ⁠multiple incidents affecting store cooling systems.

The temperature of freezers at several Swedish stores rose suddenly overnight, store operators ICA and Coop said.

Meanwhile, the Belga news agency reported overnight temperature increases at dozens of ⁠⁠Ahold Delhaize stores in Belgium and Luxembourg, which were blamed on a cyberattack, quoting refrigeration company ⁠⁠Sabcobel’s chief ⁠⁠executive ⁠⁠Stephan Moelans.

A spokesperson for the supermarket chain earlier said an “IT incident” had affected its fridges and freezers. The company is investigating the incident.

Ahold Delhaize reported a cybersecurity incident to Dutch police last month.

The cyberattack on refrigeration systems at hundreds of supermarkets in France raised the temperature of fridges and freezers to as high as 50 degrees Celsius (122F), spoiling food and causing fires at several stores.

One Swedish store said in a social media post on Monday that the temperature of its refrigerators and freezers had been set to the same temperature as during the cyberattack in France.

“We are aware that a limited number of stores were affected by an incident overnight, which impacted their refrigeration and freezer systems,” a spokesperson for privately held ICA told Reuters in an email.

Privately held retailer Coop told Swedish daily Aftonbladet that six of its stores had been affected by similar incidents.

据报道，在法国发生类似袭击事件数周后，数十家商店的制冷系统出现温度升高的情况。

瑞典、比利时和卢森堡的杂货店冷藏系统温度可能因网络攻击而升高。

瑞典国家网络安全中心负责人约翰·比洛周一向路透社证实，该中心正在应对多起影响商店冷却系统的事件。

瑞典多家商店的冷冻柜温度一夜之间突然升高，商店运营商ICA和Coop表示。

与此同时，比利时通讯社 Belga 报道称，比利时和卢森堡数十家 Ahold Delhaize 门店一夜之间温度升高，制冷公司 Sabcobel 的首席执行官 Stephan Moelans 将此归咎于网络攻击。

该连锁超市的一位发言人早前表示，一起“IT故障”影响了其冰箱和冷柜的正常运行。该公司正在对此事进行调查。

Ahold Delhaize 上个月向荷兰警方报告了一起网络安全事件。

法国数百家超市的制冷系统遭到网络攻击，导致冰箱和冰柜的温度高达 50 摄氏度（122 华氏度），造成食物变质，并在多家商店引发火灾。

瑞典一家商店周一在社交媒体上发帖称，其冰箱和冰柜的温度已设置为与法国遭受网络攻击时相同的温度。

“我们了解到，昨晚发生的一起事件影响了部分门店的制冷和冷冻系统，”私营企业ICA的一位发言人在一封电子邮件中告诉路透社。

私营零售商 Coop 告诉瑞典日报《晚报》，其旗下六家门店都受到了类似事件的影响。
