Security vendor Group-IB identified malicious code as a new JavaScript sniffer (JS sniffer) that it has named GMO. Six of the e-commerce sites are US-based and one, belonging to footwear maker Fila, is based in the UK. GMO is one of at least 38 families of JS sniffers designed to steal payment card data and credentials from online stores. Such tools can be used to steal data on thousands of customers of online stores, security vendor says. The GMO campaign is similar to but much smaller than one involving Ticketmaster UK last year.”]
