A novel Magecart skimmer skimmer script with support for 57 payment gateways from all over the world has been discovered. The payment card skimmer is already injected within dozens of Magento-powered e-commerce websites. Magecart groups have been active since 2015 and represent a continuously evolving cyber threat behind attacks against high profile international organizations like Ticketmaster, British Airways, OXO, and Newegg, as well as various small retailers like MyPillow and Amerisleep. The malicious campaigns are still going strong given that security outfit Group-IB discovered 2,440 websites during early April.
