The supermarket fridge hack exposes the cracks in tech vision of an ‘internet of things’

the gist

On the night of 11-12 October 2026 hackers remotely manipulated refrigeration systems at hundreds of French supermarkets, with temperatures reportedly reaching 50°C and food worth millions of euros spoiled. Similar incidents followed in early November in Belgium, Estonia, Finland, Ireland, Luxembourg, the Netherlands and Sweden, and UK food suppliers were targeted too. French officials blamed Iran's Revolutionary Guards; others had suspected Russia, which denies it. Attackers reportedly stretched defrost cycles from about one hour to eight while delaying alarms. More than 3,100 refrigeration controllers were still visible online on 5 November.

how it works

Refrigeration controllers let engineers monitor and adjust settings over the internet, which is handy when a freezer fails at night. Attackers can scan the internet for the same controller model and exploit the same weakness across many businesses. A controller may accept a change that is physically dangerous, which is why experts call for independent safeguards and local manual controls.

so what

Cyberattacks are no longer only about stolen data: they can wreck physical systems everyday life relies on, including hospital, pharmacy and warehouse cold chains. The attacks raise the question of who is responsible for securing connected devices that outlast their protections.

the bigger pattern

Connected industrial devices have been used before: the 2010 Stuxnet worm damaged Iranian centrifuges and the 2016 Mirai botnet hijacked cameras and routers. The pattern is that convenience features like remote access become attack paths when devices are never updated.

fun fact

The Mirai botnet of 2016 was built largely from poorly secured home cameras and routers.

Trump and Netanyahu reportedly clash over whether to resume military action against Iran

the gist

Israeli reports also say the cabinet directed the military to prepare for a possible new attack on Iran.

so what

The United States and Israel have been closely aligned on Iran's nuclear programme and regional threats, so open disagreement between their leaders over military strategy is unusual and closely watched. Whether to resume strikes is a decision with consequences for shipping, oil markets and the wider Middle East.

fun fact

Benjamin Netanyahu has served as Prime Minister of Israel for more years in total than any other person.

Angkor was the largest pre-industrial city on Earth, covering about 3,000 square kilometres

the gist

Angkor, near Siem Reap in northern Cambodia, was the capital of the Khmer Empire, which ruled much of mainland Southeast Asia between roughly the 9th and 15th centuries. At its height the city spread across about 3,000 square kilometres, making it the largest pre-industrial city on Earth by area. Its growth depended on water: huge reservoirs called barays, along with canals and embankments, stored monsoon rain and carried it to rice fields. That system let farmers harvest more than once a year and fed a very large population through the dry season. The temple complex of Angkor Wat, built in the early 12th century, is the best-known monument and still stands at the heart of the park.

how it works

The Khmer kings built enormous rectangular reservoirs that caught monsoon rain during the wet season. Earthen dykes and canals moved that water into rice paddies, so farmers could grow crops across much of the year. The surplus food supported craftsmen, builders and the workforce that raised the temples.

so what

Angkor shows how a society without industrial machinery could build a city on a scale that rivals modern metropolises, using engineering and water management instead. Some historians link its decline to drought, flooding and shifts in its water systems, which makes it a long-running case study in how cities depend on managing water. The site is a UNESCO World Heritage Site and one of the most important archaeological landscapes in Southeast Asia.

The outline of Angkor Wat appears on the national flag of Cambodia.
