Jaguar Land Rover factory staff have reportedly been told to work from home until at least next Tuesday as it battles the fallout of a major cyber attack.
The luxury carmaker has paused production at its factories in Halewood on Merseyside and Solihull in the West Midlands, as well as at its engine manufacturing site in Wolverhampton.
Production workers are said to have been told not to return to work until September 9, with the situation under review.
Jaguar Land Rover (JLR) revealed on Tuesday that production and sales have been "severely disrupted" following a hack.
The UK car manufacturer, owned by India's Tata Motors, shut down systems on Sunday after becoming aware of issues affecting its global operations.
It is the latest setback for JLR as it deals with the impact of US tariffs on the sector and weak consumer confidence.
The attack also comes at a crucial time for car firms, with September the month when new registration plates are released, traditionally boosting demand for new motors.
It is understood the hack is also affecting repairs to JLR's vehicles, as dealerships and garages are unable to order new parts, while some customer handovers are also said to be impacted.
On Wednesday, a group of young hackers who targeted Marks and Spencer and other British brands reportedly claimed they were also behind the JLR attack.
The BBC reported that the gang bragged about the hack on instant messaging platform Telegram and shared screenshots purporting to be from the car manufacturer's internal IT system.
It comes after a spate of cyber attacks across the UK retail sector earlier this year, with M&S, the Co-op and Harrods among those worst affected.
The gang made the claims on a Telegram channel which is called Scattered Lapsus$ Hunters, a combination of three English language speaking, hacking groups known as Scattered Spider, Lapsus$ and ShinyHunters.
Scattered Spider has been blamed for the attacks on British retailers earlier this year, after which M&S stopped online sales for around six weeks and warned that the incident could cost it around £300 million.
Four young people were arrested for their suspected involvement in the April attacks and have been subsequently bailed.
JLR said earlier this week it was "working at pace" to restart its operations across retail and production sites.
The company stressed there was "no evidence" that any customer data has been stolen in the attack.
