Europe’s fridge hacks just taught the drinks industry a lesson Africa already knew

Across much of Africa, a reliable cold chain is not something a distributor can take for granted. The International Institute of Refrigeration estimates that only 47% of the food that needs refrigeration worldwide actually receives it, that around 13% of global food production is lost as a result, and that these losses fall mostly on developing countries [19]. For anyone moving chilled goods from a port to an inland retailer, a cooler that stops working is not an emergency. It is part of the job.

Europe has the cold chain that much of Africa is still building — and in October and November it learned that even a complete one can be switched off remotely. On the night of October 11–12, 2026, attackers accessed internet-connected refrigeration controllers in hundreds of French supermarkets, including Intermarché, Carrefour and Monoprix stores, and forced them into defrost mode; Intermarché’s chief executive put the losses at tens of millions of euros in a single day [1][2][3]. On Monday November 2, a second wave hit stores in eight more countries, from Belgium and the Netherlands to Sweden and Estonia [4][5]. Coop Sweden has since disconnected its refrigeration from the internet [5].

Both waves exploited legacy controllers running outdated software. Two days after the French attack, Reuters found at least 4,500 Danfoss refrigeration interfaces still reachable from the public internet, although it could not establish how many were vulnerable [2]. Richard Horne, head of the UK’s National Cyber Security Centre, told Reuters the fridge attacks are an early sign of more frequent disruptions as old technology fails to keep pace with hackers [5]. The Pentagon, meanwhile, is treating freezer failures at US military commissaries in August as a suspected hack and is coordinating with French authorities [6].

Most beverages sold in those same supermarkets were unaffected when coolers turned off. Beer, soft drinks, energy drinks and juices from concentrate sit on ambient shelves. A cooler failure costs them nothing.

Frozen and dairy products were the obvious victims. Ice cream, frozen meals, milk, yoghurt and fresh cream must stay cold, and everyone knows it.

But one growing beverage category sits on both sides of this line at the same time: ready-to-drink iced coffee.

Ready-to-drink coffee is not new: Japan’s UCC launched the first canned milk coffee in 1969 and has sold more than 15 billion cans since [12]. Today the global RTD coffee market is estimated at around $31 billion in 2026 and projected to reach roughly $60 billion by 2034 [7]. Milk-based products are the largest segment, at about 38% of the category [8]. Supermarkets and hypermarkets account for over 40% of sales [9]. Yet two products standing side by side in the same cooler can have completely different supply chains behind them.

Chilled iced coffee must stay refrigerated from factory to shelf. Shelf life is typically a few weeks. It needs refrigerated trucks, cold storage and unbroken temperature control at retail. When the cooler fails, the stock is lost. The best-known European example is Emmi Caffè Latte, the Swiss brand that leads the Western European cold coffee market and is sold chilled with a typical shelf life of around four weeks [10][11].

UHT aseptic iced coffee is sterilised at ultra-high temperature and sealed in sterile packaging. It needs no refrigeration during transport or storage and keeps for many months at room temperature. When a cooler is switched off, the product is simply at room temperature — the condition it was designed for. In Europe, one example is HELL Ice Coffee, a Hungarian canned milk coffee made, according to the company, with real coffee and 75% cow’s milk [13].

Both types contain real milk and real coffee. Both usually sit in the same cooler, because consumers prefer iced coffee cold. The difference is invisible to the shopper, but it defines everything behind the shelf.

If ambient products are safer to distribute, why does chilled coffee dominate European supermarkets? There are good commercial reasons.

Shoppers associate cold with fresh, high-quality and safe, especially for dairy [14]. The perception is so strong that many aseptic beverages are deliberately placed in chillers to match it [15]. In Europe, growth has been led by chilled milk-based drinks in lidded cups, which suit on-the-go and indulgent occasions and allow larger formats and frequent new flavours [16]. The chilled aisle is also where impulse purchases and higher margins sit — which is why Nescafé chose it for its RTD iced latte launch in the UK and Ireland in May 2026 [17].

None of this changed in October. A product that sells well from the chiller still sells well. What changed is the risk attached to the supply chain behind it.

UHT aseptic processing is the most expensive way to preserve a milk-based drink. The production lines require far higher capital investment than conventional pasteurisation, and dairy-grade aseptic filling into cans is rare: only four factories in Europe can do it, one of them being the HELL Energy plant in Szikszó, Hungary, which Eurofound’s European Restructuring Monitor describes as the world’s largest factory making and filling its own aluminium drink cans on one site [13][18].

That cost, however, stays at the factory. Downstream, the economics reverse. Romeo Berthier, a business development manager at JBT Marel — an equipment supplier that sells both UHT and pasteurisation systems — and a master’s candidate in food science, notes that chilled products are more expensive per package because of their distribution method and leave more room for spoilage if the cold chain breaks, while shelf-stable products are “often microbiologically safer than their refrigerated counterparts” [15].

The wider numbers support this. The International Institute of Refrigeration’s estimate of a 13% global loss from inadequate refrigeration has already been mentioned [19]. A 2020 survey of 210 US supply chain managers, commissioned by the tracking vendor Cloudleaf, found food and beverage respondents reporting average annual losses of $71 million from cold chain failures — a vendor survey, but a rare attempt to put a figure on the problem [20]. The October and November attacks added a new line to that calculation: deliberate sabotage that can hit hundreds of locations in one night.

The attacks did not create the cold chain problem. They made it impossible to ignore. As Claroty’s chief technology officer Amir Preminger observed after the French attack, refrigeration controllers are often assumed to sit on isolated networks when many are directly exposed to the public internet [21].

For the RTD coffee category, the timing matters. The category is expanding into Africa, the Middle East, Southeast Asia and Latin America, where reliable cold chains range from expensive to nonexistent. In those markets the choice between chilled and ambient is not a matter of taste; it is a matter of whether the product arrives at all.

Anyone entering or expanding in iced coffee now faces a clear question: build the business on a product that depends on an unbroken cold chain, or on one designed to work without it? The chilled aisle will keep its loyal shoppers. But after two waves of attacks in four weeks, the supply chain behind the shelf has become part of the decision.
