New York sues Dunkin' Donuts over cyberattacks

The chain failed to protect customers whose accounts were targeted in a series of “brute force” cyberattacks

NEW YORK: The parent of Dunkin’ Donuts was sued on Thursday by New York Attorney General Letitia James, who accused the chain of failing to protect hundreds of thousands of customers whose accounts were targeted in a series of “brute force” cyberattacks.

James said Dunkin’ Brands Group Inc did nothing in 2015 to protect 19,715 customers whose accounts had been targeted in a single five-day period, after learning about the problem from its own app developer.

She said the Canton, Massachusetts-based company failed to notify affected customers of the breaches, reset their passwords or freeze their Dunkin’ Donuts cards.

James also said Dunkin’ failed to adopt appropriate safeguards to limit future attacks, despite customer reports of continuing fraud on their accounts.

That failure came to roost in late 2018 when more than 300,000 customer accounts were accessed in new attacks, James said in the lawsuit, which concerns accounts created through Dunkin’s website or free mobile app.

“Dunkin’ failed to protect the security of its customers,” James said in a statement. “Dunkin’ sat idly by, putting customers at risk.”

The company did not immediately respond to a request for comment.



James’ lawsuit filed in a New York state court in Manhattan seeks civil fines, restitution and other remedies for alleged violations of state consumer protection and business laws.

“Dunkin’s representation to consumers that it used reasonable safeguards to protect consumers’ personal information, and the company’s statements concerning the 2018 breach, were false and misleading,” the complaint said.
