Macy's customers were hit by the second data breach in October. Countless numbers of credit cards may be involved.
The breach lasted one week, between October 7 and October 15. As a result, the customer information that could get into hackers' hands include names, addresses, phone numbers, email addresses, credit card numbers, card verification codes, and expiration dates. Retailer did not specify how many customers were affected.
Macy's said they reported the incident to federal law enforcement and relevant banks and card issuers, including Visa, Mastercard, American Express and Discover. The retailer also notified affected customers and will provide customers with additional information and instructions on how to enroll in consumer protection services at no cost.
This security breach is not the first time Macy's has been targeted by hackers. Last year, Macy's admitted that the breach lasted one month causing credit card data and passwords of thousands of the retailer's online customers to be stolen by cyberthieves.
