Researchers have found links between Magecart-based Web skimming attacks and a sophisticated cybercrime group dubbed Cobalt. Cobalt is a cybercrime gang that specializes in stealing large amounts of money from banks and other financial organizations. Magecart is an umbrella moniker for groups that break into e-commerce websites and inject malicious JavaScript files into checkout pages to steal payment card details. Researchers also found evidence of Magecart Group 4 performing server-side skimming, which is harder to detect than the typical JavaScript injections.”]
