Flagstar Data Breach Investigation

Girard Sharp attorneys are investigating reports of a December 2020-January 2021 data breach that affected Flagstar Bank.

The breach reportedly involves Accellion, Inc., a third-party provider of hosted file transfers. Accellion has confirmed there was unauthorized access to personal information belonging to customers and employees of Flagstar. The exposed information may include names, Social Security numbers, phone numbers, and addresses. The data breach may have also exposed the personal information of former customers or people who never had an account at the bank.

More Information on the Flagstar Breach

Flagstar partners with Accellion, a third-party software vendor, to transfer large files, which can include sensitive personal information. Flagstar reportedly learned from Accellion of a breach of its electronic systems on January 22. According to Accellion, it notified Flagstar customers of the breach on December 23. Flagstar first announced the breach on its website on March 5, but it did not state that Social Security numbers had been exposed. Two weeks later, Flagstar disclosed that the compromised information includes Social Security numbers and began notifying victims of the breach by email and U.S. mail.
