The luxury-goods conglomerate - which designs, manufactures, distributes, and sells jewellery and watches, among other items - has revealed an "unauthorised party" obtained "limited client information" after its website was hacked.

Cartier said in a statement: "An unauthorised party gained temporary access to our system."

The company has sent an email to some customers informing them about the cyber attack, but Cartier insisted customers' "passwords, credit card details or other banking information" had not been stolen.

Part of the note read: "The affected information did not include any passwords, credit card details or other banking information."

The news comes just weeks after a swarm of cyberattacks, which hit companies including Marks and Spencer and Co-op.

HSBC UK chief executive Ian Stuart recently told how cybersecurity is "very much at the top of the agenda" - because they are being "attacked all the time".

He told the Treasury Committee of MPs: "It does keep me awake.

"Because we can be attacked and we are being attacked all the time.

"Cybersecurity is now very much at the top of our agenda."

What's more, Lloyds Bank chief executive Charlie Nunn described the UK as the "home of fraud".
