This week, Target revealed that information has been stolen from as many as 110m customers in it’s pre-Christmas data breach. This number is substantially more than the amount that Target initially said were affected. The chain also indicated its sales have been hurt by the breach, cutting its forecast for fourth-quarter earnings.E-mail, mailing addresses and phone numbers were all stolen during the breach as well as card details.
Target had announced in December that 40m debit and credit cards had been affected between 27 November and 15 December 2013. But the net has now been cast wider, with more shoppers potentially impacted. Soon after, that number increased to a potential 70m customers affected – but now it appears that figure is much higher.
The company told customers Friday that its ongoing investigation of the breach has shown that more personal information had been stolen than it was aware of before and more customers were affected. It previously disclosed to customers that names, credit and debit card numbers, card expiration dates, PINs and the embedded code on the magnetic strip on the back of cards had been stolen.
The Minneapolis company said it immediately told authorities and financial institutions once it became aware of the breach and that it is teaming with a third-party forensics firm to investigate the matter and prevent future breaches. It said it is putting all “appropriate resources” toward the issue. The investigation is ongoing.
Target have said that no customers will be liable for any fraudulent charges made on their cards.
Target has 1,797 U.S. stores and 124 in Canada.
