Flagstar Bank is notifying 1.5 million customers of a data breach where hackers accessed personal data during a December cyberattack.
According to data breach notifications sent to exposed customers, Flagstar experienced a security incident in December 2021 when intruders breached the bank's corporate network.
Based on information submitted to the Office of the Maine Attorney General, the data breach affected 1,547,169 people in the United States.
Bleeping Computer contacted Flagstar with further questions, including what types of data have been potentially exposed and why it took so long to discover the breach, but the response didn't provide any additional details.
This breach resulted in Flagstar Bank being extorted by Clop, its customers having their data exposed to cybercriminals, and the financial institute ending its collaboration with the Accellion platform.
Samples of stolen data, including names, SSNs, addresses, tax records, and phone numbers, were eventually published on Clop's data leak site.
