The government is exploring options to support JLR's supply chain businesses, some of which are at risk of viability, though a Covid-style furlough scheme is not considered viable.
JLR reportedly lacked cyber insurance before the attack, meaning it may have to cover significant losses, estimated at £50m per week in lost production.
Ministers have urged JLR, which has a cash balance of over £3bn and is backed by the wealthy Tata Group, to support its supply chain and protect jobs.
The incident has been described as a 'wake-up call' for British industry regarding cyber security, highlighting the vulnerability of companies to such attacks.
