If hackers can take control of a supermarket freezer, how vulnerable is other tech?

By · Published by Everything Blog

In short

UK Cyber Defence researchers detected over 800 British retail refrigeration and building-control interfaces exposed to the public internet, leaving them open to password guessing or software exploits. While the National Cyber Security Centre found no UK disruptions from the November incidents, experts warn that physical stock can be ruined if temperature controls are altered. Remote mobile links used to oversee water facilities and power plants present similar risks, particularly for smaller utility providers relying on older, less-secure equipment. In response, retail executives and government officials are actively sharing intelligence to reinforce supply chain resilience against emerging…

Supermarkets across Europe have been hit by a suspected cyber-attack affecting their fridges and freezers, and raising concern about the vulnerabilities of internet-connected hardware from industrial machinery to humble domestic appliances.

Smart devices which are connected to the internet can include fridges, central heating, and even washing machines.

And while that makes them easier to control remotely, in theory, any device which goes online can potentially be exploited by malicious actors.

However, that doesn't mean hackers can easily take control of it, and big brands generally go to great lengths to make sure their tech is secure.

Exploits have been found before in some devices. In 2015, researchers demonstrated how a vulnerability in a Samsung smart fridge could allow them to intercept internet traffic.

But there's no evidence domestic appliances are being targeted in the cyber-attacks which targeted supermarkets in November.

Ciaran Martin, former chief executive of the UK's National Cyber Security Centre (NCSC) says manufacturers needed to do more to make connected devices secure.

"There's a lot more that we need to demand of big tech to…
