Nationwide shoe shop Office has become the latest company to fall victim to a cyber attack, forcing the retailer to warn its customers to change their account passwords.
The high street chain confirmed its online security had been breached, following similar attacks on eBay and Spotify, but said customers' financial data had not been compromised.
The retailer has emailed users urging them to change their login details on other sites.
Office chief executive Brian McCluskey said: "We take such a threat very seriously and have been in communication with our customers to advise them of the matter.
"We can confirm that no credit card, debit card, Paypal or bank details were compromised in any way. In addition we have reported the matter to the relevant authorities."
Last week eBay announced that a breach in their security had given hackers access to more than 100 million users while Spotify updated its Android App after a user account was deemed to have been compromised.
