Security Breach at Flagstar Bank Affects 1.5 Million Clients
Cybercriminals Acquired Access to 1.5 Million Flagstar Bank Customers’ Personal Information.
Flagstar Bank is a financial institution with its headquarters located in Michigan and is one of the major residential mortgage servicers in the United States, being ranked among the top five largest banks in the country.
During a cyberattack in December, cybercriminals gained access to the personal information of 1.5 million Flagstar Bank clients, and the bank is now informing those customers of the breach.
A data breach occurs when an unauthorized individual gains access to confidential, sensitive, or protected information. Without permission, files from a data breach are viewed and/or shared.
Intruders broke into the corporate network of Flagstar Bank in December 2021, as shown by the data breach notices that were issued to clients whose information had been compromised, causing the bank to suffer a security problem.
The bank found out on June 2nd, after conducting an inquiry into the matter, that the threat actors had gained access to critical consumer information, including complete customer names and social security numbers.

As reported by BleepingComputer, a total of 1,547,169 people throughout the United States were affected by the data breach.
This is the second serious security breach that has hit Flagstar and its customers within the last year. In both cases, the breach occurred within the previous year.
In January of 2021, a group of cybercriminals operating under the name Clop exploited a zero-day vulnerability that was present in the servers used by Accellion FTA. This allowed them to obtain access to the computer systems used by the bank.
This occurrence has ramifications for a significant number of firms, including Bombardier, Singtel, the New Zealand Reserve Bank, and the State Auditor office in Washington, that conducted business with Accellion.
As a direct result of this security compromise, Flagstar Bank was blackmailed by Clop, the personal information of its customers was made accessible to hackers, and the financial institution severed its cooperation with the Accellion platform.
In the end, samples of the stolen data were uploaded on Clop’s data breach website. These examples included people’s names, Social Security numbers, homes, tax information, and phone numbers.
