The payment card-siphoning Magecart group has struck again; this time injecting web-skimming scripts into the subscription website for the Forbes print magazine. In just the last week, Magecart web skimmers have also been discovered on at least seven other websites with the majority of compromises occurring around May 10. Magecart is known for its use of web-based, digital card skimmers, and uses scripts injected into websites to steal data that s entered into online payment forms on e-commerce websites.
