UK manufacturers face rising hacking risk as survey shows 30% were hit last year

Big companies describe being under constant threat but only half have a plan in place to respond to an attack

Nearly a third of British manufacturers have been hit by a cyber-attack on them or a company in their supply chain, according to a survey that highlighted the growing hacking risk to companies.

The findings come almost a year after Britain's largest automotive employer, JLR, was hit by an attack that forced it to halt production for weeks.
