A group of young English-speaking hackers are claiming to be behind the cyber attack which has halted the global production lines of Jaguar Land Rover (JLR).
The group is bragging about the hack on the messaging app Telegram, sharing screenshots apparently taken from inside the car maker's IT networks.
The gang is also responsible for a wave of cyber attacks on UK retailers including M&S in the spring - and are calling themselves "Scattered Lapsus$ Hunters".
"Where is my new car, Land Rover," the hackers - who are thought to be teens - posted to taunt the company.
The BBC has approached JLR for comment.
