Clothing company Cotton Traders has been found to have had 38,000 customer credit card numbers taken from its website in an attack earlier this year. The firm has not directly confirmed the size of this attack as yet.
Barclaycard, the firm's card processor, was contacted as soon as the breach was discovered, and all cards were blocked. Security experts were brought in to fix any holes in the site, although the exact point of entry was not discovered.
The firm has said customers worried about their cards should contact their card provider.
