The second of a pair of class action lawsuits over data breaches earlier this year that compromised financial information of Saks & Co. customers has made its way from the Central District of California to federal court in Manhattan.

News of the security breach impacting Saks and other retail brands owned by Hudson’s Bay Co. became public in April. According to the complaint, a well-known international hacking group was able to steal and release the information for over 5 million debit and credit cards. The breach, according to reports, affected the point-of-sale systems at a number of Saks-brand stores, and lasted from around the beginning of July 2017 through March 2018.
