Researchers at RiskIQ have been tracking a series of web-based credit card skimmers known as Magecart. We take a closer look at attacks on Ticketmaster, British Airways, NewEgg and Shopper Approved payment card pages. 
Yonathan Klijnsma is lead of threat research at RiskIQ, and he guides us through what they've learned.
