Web Credit Card Skimmer Steals Data from Another Credit Card Skimmer
MalwareBytes is reporting a weird software credit card skimmer. It harvests credit card data stolen by another, different skimmer:
Even though spotting multiple card skimmer scripts on the same online shop is not unheard of, this one stood out due to its highly specialized nature.
“The threat actors devised a version of their script that is aware of sites already injected with a Magento 1 skimmer,” Malwarebytes’ Head of Threat Intelligence Jérôme Segura explains in a report shared in advance with Bleeping Computer.
“That second skimmer will simply harvest credit card details from the already existing fake form injected by the previous attackers.”
