Cartier and The North Face have confirmed customer data breaches following separate cyber attacks.
The North Face detected a 'small-scale' attack in April, while Cartier reported an 'unauthorized party' gaining temporary access to their system.
Both companies had customer names and email addresses stolen, but no financial information was compromised.
The cyber attacks on these retailers highlight an increasingly threatening landscape for the retail sector, with a growing number of high-profile breaches taking place.
