JLR hack 'is costliest cyber attack in UK history'11 minutes ago Share Save Joe Tidy Cyber correspondent, BBC World Service Share SaveReutersThe cyber attack on Jaguar Land Rover (JLR) will cost an estimated £1.9bn and be the most economically damaging cyber event in UK history, according to researchers. JLR declined to comment on the research but said it is bringing portions of manufacturing back online in a phased approach. The CMC is an independent, non-profit organisation that analyses and categorises cyber events, which impact the UK financially. It has classified the JLR incident as a Category 3 event, which is significant. Although the National Cyber Security Centre also categorises cyber attacks depending on how severe they are, it does not publish its findings.
