Supermarkets in Sweden, Belgium, Luxembourg, Ireland and Estonia were on Monday hit by problems with freezers and fridges that were apparently caused by cyberattacks, forcing some to dispose of ruined food.
The problems follow a case last month in which attackers remotely took control of refrigeration systems in hundreds of supermarkets and independent stores across France, sending temperatures soaring.
Gustaf Nilsson, a spokesperson for Sweden’s ICA Group supermarket chain, told the TT news agency that “a limited number” of stores were affected overnight by an incident that affected refrigeration and freezing systems.

He declined to give a specific number.
An ICA Kvantum store in Sjobo, Sweden, said its fridges and freezers had been hacked and set to 50oC. In a Facebook post, it said staff were discarding affected products.
The Coop chain said that six of its stores in central Sweden had problems with their fridges and freezers, TT reported, though it did not immediately have details.

The Delhaize chain said that an “IT incident” had affected refrigeration systems in several dozen of its stores, mostly in Belgium, but also a few in neighboring Luxembourg.
“In the affected stores, the range of fresh and frozen products is temporarily somewhat limited. Our distribution centers are operating normally, and there has been no disruption to deliveries to our stores,” spokesperson Sarah De Meester said.
Carrefour said a cyberattack targeting refrigeration systems had affected 15 of its more than 700 stores in Belgium, describing the impact as “extremely limited.”
In Estonia, a refrigeration technology company said attackers had accessed a computer controlling a client’s refrigeration system and raised the temperature to 50oC, public broadcaster ERR reported.
Kitman Coldtech chief executive Jann Mutso declined to identify the store, but said the attack was addressed within minutes and caused no significant damage. The Selver supermarket chain said one of its outlets was affected.
In Ireland, refrigeration systems in 13 SuperValu stores were affected by the “cyber incident,” parent company Musgrave Group said.
A spokesperson said chilled and frozen products were removed from sale as a precaution.
On Monday afternoon, the company said the incident had been “fully resolved” and “replenishment of chilled and frozen ranges in the affected stores is well under way.”
The cyberattacks in France appeared to target old systems.
Long dubbed an “air-conditioned nation,” Singapore is experimenting with cooling alternatives from chilled beams to “passive displacement” to curb its thirst for energy-guzzling air-conditioning. The city-state has the highest per-capita air-conditioner ownership rate in Southeast Asia, with about 99 percent of private residences equipped with cooling units. Singapore’s local building sector accounts for one-fifth of its emissions, while cooling itself accounts for 40 to 60 percent of a building’s energy consumption, according to studies. A stroll down Orchard Road highlights that dependence. Shoppers are greeted by blasts of cool air that waft into the street as doors swing open — a major draw
Ethiopian online influencers are pushing for their government to invade neighboring Eritrea and seize access to the sea, following its success against rebel and Eritrean forces in the past few weeks. The Ethiopian army has advanced right up to the border after repelling an offensive by rebels in the northern Tigray State who were supported by Eritrean troops. Ethiopian Prime Minister Abiy Ahmed has repeatedly said that securing a base on the Red Sea is a vital national objective for Ethiopia, which lost its coastline when Eritrea gained independence in 1993. Some online influencers say that the opportunity to invade has arrived. “The time
Beijing yesterday dismissed as “groundless speculation” a report that said Nvidia CEO Jensen Huang (黃仁勳) was the target of a Chinese spy plot. The article by the New York Times, published on Thursday, said that US intelligence officials concluded that a Chinese executive linked to a Singapore-based data center company had been funneling information to Beijing. “The report in question is based on groundless speculation and is nothing more than an attempt to smear China,” Chinese Ministry of Foreign Affairs spokesman Guo Jiakun (郭嘉昆) told a regular briefing. China is in a race for tech dominance with the US, which restricts the export
33 MISSING: The unprecedented number of empty seats at the fifth plenum, an annual gathering of top officials, serve as a symbol of the extent of the purges under Xi Jinping China expelled a record number of officials from the Chinese Communist party (CCP) as it concluded a major political gathering, which saw an unprecedented number of empty seats indicating the scale of the purges under Chinese President Xi Jinping (習近平). A record 33 members were expelled at this week’s fifth plenum, a gathering of top officials that takes place roughly once a year. Just 279 of the full and alternate members of the CCP’s Central Committee attended this week’s gathering, compared with the 376 originally named as members in 2022. That means that more than 25 percent of the original cohort were
