Cartier, Victoria’s Secret and North Face have become the latest retailers to be hacked.
The revelations follow attacks on firms including Marks & Spencer, the Co-op, Harrods and Dior in recent weeks.
Jewellery and watch maker Cartier told customers that ‘an unauthorised party gained temporary access’ to its system and ‘obtained limited client information’.
No passwords, credit card details or bank information were compromised in the attack.
North Face emailed some customers saying it discovered a ‘small-scale’ attack in April this year.
Lingerie maker Victoria’s Secret said a security incident relating to its IT systems led it to shut its website for a few days last week.
