On the 31st August 2025, the computers at Jaguar Land Rover were hacked due to a sustained and well planned cyber attack, and this caused widespread chaos throughout the whole company and ultimately a complete loss of production output. This article is about the impact to such a major hacking cyber attack on a major car manufacturer in the United Kingdom.
Not only am I a writer, but, I own a multi-national IT company which writes software, so I am well placed to understand and consider the issues facing Jaguar Land Rover last month.
Production Output
On 1st September 2025, Jaguar Land Rover confirmed a day later, that the cyber attack had now caused the production lines to be slowed to a halt.
It is not simply a case of rebooting the computer, or switching it off and back on again, because the way that these attacks work is to completely destroy the way that the computer system would operate causing the need to resort to backups being restored. Restoring backups of this magnitude will take a while due to the shear size of the computers across the manufacturing operation.
However, consider the scenario where a sustained attack over a number of weeks ensured that the backups were made ineffective as well. This is a situation facing the IT support staff trying to bring the computers back online at warp speed.
This caused the return to service of the IT suite being delayed from the 21st September to the 1st October. A full month with no production output. Production output returned slowly on 1st October 2025.
Cost to Jaguar Land Rover
Jaguar Land Rover have said that the cost to the company was approximately £50m per week. However, due to the lay off of staff, staff may be forced to find alternative employment, and this may have future staffing shortages and future knock on cost implications in attracting replacements.
Cost to the UK Economy
It is widely thought and reported that the cost to the UK economy could be as high as ten times of that to Jaguar Land Rover, or be just around perhaps £2bn, due to loss in export revenue, taxes, contractual obligations, and also incurred costs of the staff lay off.
Perpetrators
It has been difficult to track down the perpetrators, a number of groups have claimed responsibility, either working solo, or as a group of cyber attacking criminal groups. Consideration has been given to a Russian backed cyber attack, but that appears to always be blamed.
