The cyber attack against Jaguar Land Rover cost the British automaker as much as £2.1billion, according to a new report.The Cyber Monitoring Centre described the cyber attack against the manufacturer as a “category 3 systemic event”, noting that it was one of the most financially devastating events in UK history.The CMC model estimates that the cyber attack, which was first raised at the end of August, caused a UK financial impact of £1.9billion and affected more than 5,000 organisations.It stated that the modelled range of loss is between £1.6billion and £2.1billion, although it could have been much higher if operational technology were more affected.The total figure takes into account Jaguar Land Rover’s manufacturing, its supply chain and downstream organisations, like dealerships.The CMC stated that the JLR cyber attack was “the most economically damaging cyber event to hit the UK”.The vast majority of the financial impact is down to the loss of manufacturing output at JLR and its suppliers.However, the CMC estimate only takes into account UK operations, and does not account for the brand’s worldwide operations, suppliers and dealerships.The cyber attack against Jaguar Land Rover is estimated to have cost the UK economy around £1.9billion | GETTY/REUTERS Jaguar Land Rover said it would provide an update on the Halewood site soon | PA
