A Magecart credit-card skimmer was used to attack online customers of the retailer Claire's for a month and a half, according to researchers. "Following common Magecart malpractice, payment skimmers were injected and used to steal customer data and cards," according to Sansec.
Magecart attackers have compromised web shops belonging to large retail chains Claire's and Intersport and equipped them with payment card skimmers. How the attackers managed to compromise the web shops is still unknown, but they started planning the attack a month before actually executing it.
Hacking groups are continuing to leverage misconfigured AWS S3 data storage buckets to insert malicious code into websites in an attempt to swipe credit card information and carry out malvertising campaigns. These virtual credit card skimmers, also known as formjacking attacks, are typically JavaScript code that Magecart operators stealthily insert into a compromised website, often on payment pages, designed to capture customers' card details in real-time and transmit it to a remote attacker-controlled server.
A card-skimming Magecart malware infection lingered on a British outdoor clothing retailer's website without detection for nearly eight months despite regular security scans. The warning continued: "This code copied card details entered, destined for PayPal and additionally sent them on to the attacker's server. The data transferred was name, address, card number and CVV code."

The client-side landscape has been overrun by third-party script attacks executed by malicious attackers utilizing formjacking or other methods made famous by the Magecart attack group. As third parties change their behavior from user to user, DAST is largely ineffective in detecting attacks on large production networks and completely ineffective at preventing these types of attacks.
A Magecart threat actor tracked as "Group 7" has been using a skimmer that creates iframes to steal payment card data, RiskIQ reveals. In some cases, the compromised websites were abused to host the skimming code, load the code on compromised websites, and exfiltrate stolen data.
Cybersecurity researchers today uncovered an ongoing new Magecart skimmer campaign that so far has successfully compromised at least 19 different e-commerce websites to steal payment card details of their customers. MakeFrame attacks have been attributed to Magecart Group 7 for its approach of using the compromised sites to host the skimming code, load the skimmer on other compromised websites, and siphon off the stolen data.
Researchers have observed a new skimmer from the prolific Magecart Group that has been actively harvesting payment-card data from 19 different victim websites, mainly belonging to small- and medium-sized businesses, for several months. "In some cases, we've seen MakeFrame using compromised sites for all three of its functions - hosting the skimming code itself, loading the skimmer on other compromised websites and exfiltrating the stolen data," Herman and Ihm wrote.
A faction under the Magecart umbrella, Magecart Group 8, targeted the website of the blender manufacturer, NutriBullet, in an attempt to steal the payment-card data of its online customers. Yonathan Klijnsma, threat researcher with RiskIQ, said in a Wednesday post that a JavaScript web skimmer code was first inserted on the website of the blender retailer on Feb. 20, specifically targeting the website's checkout page, where customers input their payment information.
