Details of the breach were reported by the security research firms RiskIQ (which exposed the code behind the British Airways attack) and Volexity Threat Research today. The attack was shut down by NewEgg on September 18, but it appears to have been actively siphoning off payment data since August 16, according to reports from the security researchers. Yonathan Klijnsma, head researcher at RiskIQ, said that the methods and code used are virtually identical to the attack on British Airways—while the Ticketmaster breach was caused by code injected from a third-party service provider, both the BA breach and the NewEgg attack were the result of a compromise of JavaScript libraries hosted by the companies themselves.NewEgg is investigating the matter and promises to publish a FAQ page on Friday. Customer accounts that are at risk will be notified as soon as possible.
