SLIDELL, La.—The Bank of Louisiana is leading a class-action lawsuit on behalf of banks and other financial institutions in the wake of the Marriott International data breach that revealed personal information – including names, addresses, payment card details and passport numbers – of as many as 500 million customers.
Marriott was informed in September of a breach that impacted its Starwood guest reservation database. On Nov. 19, the company determined there had been unauthorized access to the data going back to at least 2014.
In the lawsuit filed with the U.S. District Court for the District of Maryland, Bank of Louisiana argues that Marriott had inadequate data security measures and that the bank – and other financial institutions that issued cards compromised in the breach – incurred costs related to reissuing cards, refunding unauthorized transactions caused by the breach, increasing fraud monitoring efforts and responding to higher numbers of complaints and inquiries.
Following news of the data breach, NAFCU urged leaders of the Senate Banking and House Financial Services Committees to take action on a national data security standard, noting that this Marriott breach is one of the largest breaches of personal data.
