Macy's has confirmed a data breach following the discovery of Magecart malware on its checkout page and wallet page, which is accessed through My Account, the retailer reports.
In a letter to customers, the retailer says it was alerted to a "suspicious connection" between Macy's and another website on October 15. An investigation determined malicious code was added to two macys.com web pages on October 7. The code was "highly specific" and only allowed a third party to capture data submitted by customers on the wallet page and checkout page if credit card data was entered and "place order" was clicked. Its teams removed the code on October 15.
During the week that the malicious code was live, Macy's reports cybercriminals may have potentially accessed customer data including first name, last name, address, city, state, ZIP code, phone number, email address, and their payment card's full number, security code, and month and year of expiration if this data was typed into either of the affected web pages.
Customers who checked out, or interacted with, the My Account wallet page on a mobile device or the macys.com mobile app were not affected in the incident, the company reports.
Macy's has reported the breach to federal law enforcement and hired a forensics firm to assist in the investigation. It has also shared affected payment card numbers with brands Visa, Mastercard, American Express, and Discover. The number of victims has not been confirmed.
Magecart is a constantly growing threat to retail websites. Recent data indicates the card-skimming threat has reportedly compromised more than 2 million victim websites and directly breached more than 18,000 hosts. Its many victims include, most recently, Procter & Gamble's First Aid Beauty, as well as other major companies Ticketmaster and British Airways.
