Online payment skimming (aka "MageCart") is a growing threat to digital stores. Since our first publication in 2015, we identified more than 40.000 compromised stores. In most cases, malware is inserted that will a) intercept customer data, b) divert payments or c) uses your customers for cryptojacking.
Privacy watchdogs and online regulators are increasingly handing out fines to companies who suffered a Magecart attack.
