Macy’s has disclosed a data breach – their web site was hacked with malicious scripts that steal customer’s payment information. In Magecart attacks, hackers compromise web sites to inject malicious JavaScript scripts into various sections of the web site. These scripts then steal payment information that is submitted by a customer.
The ‘Notice of Data Breach‘ issued by Macy’s said their web site was hacked on October 7th, 2019 and a malicious script was added to the ‘Checkout’ and ‘My Wallet’ pages. If any payment information was submitted on these pages while they were compromised, the credit card details and customer information was sent to a remote site under the attacker’s control.

Compliance with these standards helps retailers protect payment card data by restricting physical and digital business access.
First and foremost, retailers must ensure they are complying with the Payment Card Industry Data Security Standard (PCI DSS). Compliance with these standards helps retailers protect payment card data by restricting physical and digital business access to cardholder data and requiring multi-factor authentication for all non-console administrative access. None of these processes alone will ensure complete IT security. However, retailers can leverage compliance and incorporate cybersecurity best.....Read More

Putting a stop to code injection is one of the oldest tenets in the app sec playbook.
While we commend Macy’s for finding the breach and dealing with it only about a week after it first occurred, with the right precautions this is easily avoidable. Putting a stop to code injection is one of the oldest tenets in the app sec playbook.
That said, with modern applications, consisting of multiple layers, components and interstitial APIs, that task is becoming increasingly difficult. Malicious code can also be unwittingly inserted by insiders. Stopping these types of attacks.....Read More

Online retailers like Macy’s are prime targets for Magecart.
The recent data breach at Macy's is unfortunate, but not surprising. Magecart is responsible for cyberattacks on many major companies including Ticketmaster, British Airways, NewEgg, Magento and more. Online retailers like Macy’s are prime targets for Magecart, because data is easily stolen during checkout, often through third parties, as customers enter their credit cards. For this reason, organizations must put processes in place to manage and review their susceptibility to the Magecart.....Read More

Treat everyone else as a potential threat.
The challenge with preventing cross-site scripting attacks is identifying which code should be running on a site, which ones shouldn't. Until site owners know all the domains that are called by code on their site, they won't be able to distinguish who's authorized to be there, and who isn't. If they have an inventory of allowed digital vendors, they'll be able to root out unauthorized actors like those behind barn-x.com. They need to take a left of left-of-breach approach. Only allow code from.....Read More
Javelin’s 2019 Identity Fraud Study reported $4 billion in ATO losses last year and new account fraud losses of $3.4 billion.
The Macy’s data breach is concerning for two reasons. First, it released even more personally identifiable information into the dark web including names, emails, addresses and credit card information. This compromised data can be combined with other available information to create a “fullz,” giving criminals everything they need to commit identity theft. 2019 has been a record year for fraud and criminals are splicing together information from disconnected breaches, creating full identity .....Read More
