Quote:Magecart, the hacking group behind the British Airways hack, managed to infiltrate the website of online US retailer Newegg and stole credit card information using a skimmer as reported by a joint analysis from Volexity and RiskIQ.

The last time when Magecart was in the news they were the threat group who designed and breached the British Airways website and mobile application, and left the scene with a bounty of sensitive data from 380,000 victims.

This time the damage inflicted after hacking into Newegg's website and running a credit card skimming operation from August 14 until September 18 and affecting all customers who entered their payment data, is probably of an entirely different magnitude.

Considering that Newegg has more than 40 million shoppers visiting their website every month, it is safe to assume that Magecart newest card skimming campaign has probably collected the credit card information of millions of paying customers.
