Security researchers RiskIQ said Wednesday that Magecart inserted malicious code into the payments system of the hardware and electronics retailer and made off with charge card data.

The nasty code was running on the Newegg site from Aug. 14 until Sept. 18, according to RiskIQ, which researched the incident with cybersecurity firm Volexity. The attack affected both desktop and mobile customers, according to RiskIQ. It's unclear how many customers were hit.
