Threat actors behind web skimming campaigns are leveraging malicious JavaScript code that mimics Google Analytics and Meta Pixel scripts in an attempt to sidestep detection. Last year, Malwarebytes disclosed a campaign wherein malicious actors were observed delivering PHP-based web shells embedded within website favicons to load the skimmer code.
Target, one of the largest American department store chains and e-commerce retailers, has open sourced 'Merry Maker' - its years-old proprietary scanner for payment card skimming. A skimmer is malicious code injected into shopping sites to steal customers' credit card data at checkout.
Threat actors leveraged a cloud video hosting service to carry out a supply chain attack on more than 100 real estate websites operated by Sotheby's Realty that involved injecting malicious skimmers to steal sensitive personal information. "The attacker injected the skimmer JavaScript codes into video, so whenever others import the video, their websites get embedded with skimmer codes as well," Palo Alto Networks' Unit 42 researchers said in a report published this week.
A supply-chain campaign infecting Sotheby's real-estate websites with data-stealing skimmers was recently observed being distributed via a cloud-video platform. "In skimmer attacks, cybercriminals inject malicious JavaScript code to hack a website and take over the functionality of the site's HTML form page to collect sensitive user information," researchers explained in a Monday posting.
Security researchers discovered that attackers are also deploying a Linux backdoor on compromised e-commerce servers after injecting a credit card skimmer into online shops' websites. "After a day and a half, the attacker found a file upload vulnerability in one of the store's plugins. S/he then uploaded a webshell and modified the server code to intercept customer data."

Costco has discovered a payment card skimming device at one of its retail stores and has sent out notification letters informing customers that their card data may have been ripped off if they shopped there recently. Immediately after finally renewing my Costco membership online this morning I discovered $2200 of fraudulent credit card charges made in the UK on August 31st. So now I have a Costco membership but no credit card to use to shop there for the next seven to nine business days.
Costco Wholesale Corporation has warned customers in notification letters sent this month that their payment card information might have been stolen while recently shopping at one of its stores. Costco discovered the breach after finding a payment card skimming device in one of its warehouses during a routine check conducted by Costco personnel.
A new Magecart threat actor is stealing people's payment card info from their browsers using a digital skimmer that uses a unique form of evasion to bypass virtual machines so it targets only actual victims and not security researchers. Detecting VMs used by security researchers and sandboxing solutions that are set to pick up Magecart activity is "The most popular method" used to evade detection, Segura said.
Virtually all payment card terminals at self-checkout lanes now accept cards with a chip to be inserted into the machine. Most modern chip-based cards are significantly thinner than the average payment card was just a few years ago, but the design specifications for these terminals state that they must be able to allow the use of older, taller cards - such as those that still include embossing.
