Hundreds of counterfeit online shoe stores injected with credit card skimmer

There’s a well-worn saying in security: “If it’s too good to be true, then it probably isn’t.” This can easily be applied to the myriad of online stores that sell counterfeit goods—and now attract secondary fraud in the form of a credit card skimmer.
