UK also affected by cyber-attack which hit European supermarket fridges

After hackers targeted refrigeration systems in supermarkets and food suppliers across Europe, the National Cyber Security Centre (NCSC) says it is aware of "a couple of instances where vulnerable technology had been exploited in the UK".

The NCSC's chief executive Dr Richard Horne told the Today programme, on BBC Radio Four, that it had "worked through the night" to alert potentially affected organisations in the UK.

He said it had alerted "handfuls" of bodies, and that it was aware of a "couple of impacts".

It comes after supermarkets in countries including Ireland, Sweden, Estonia, and Belgium reported fridges being hiked in temperature on Monday.
