The JLR cyber-attack is estimated by the Cyber Monitoring Centre (CMC) to have cost £1.9bn.
It said at £1.9 billion of financial loss, this incident appears to be “the most economically damaging cyber event to hit the UK” with most financial impact being due to the loss of manufacturing output at JLR and its suppliers.
“The CMC model estimates the event caused a UK financial impact of £1.9 billion and affected over 5,000 UK organisations.
“The modelled range of loss is £1.6 billion to £2.1 billion but this could be higher if operational technology has been significantly impacted or there are unexpected delays in bringing production back to pre-event levels.
“This estimate reflects the substantial disruption to JLR’s manufacturing, to its multi-tier manufacturing supply chain, and to downstream organisations including dealerships.
“The estimate is sensitive to key assumptions, including the date JLR is able to fully restore production and the profile of the recovery; this and other assumptions and limitations are discussed later in this document.”
The Cyber Monitoring Centre bills itself as an independent, non-profit organisation, responsible for monitoring, defining, and classifying cyber events impacting UK organisations, It has an independent technical committee.
