US bank and mortgage lender Flagstar has disclosed a data breach after the Clop ransomware gang hacked their Accellion file transfer server in January.

In December, threat actors affiliated with the Clop ransomware gang began exploiting vulnerabilities in Accellion FTA servers used by organizations to share sensitive files with people outside of their organization.

On Friday, Flagstar Bank issued a security disclosure on their website and began emailing customers about a breach of their Accellion FTA server.

"Accellion, a vendor that Flagstar uses for its file sharing platform, informed Flagstar on January 22, 2021, that the platform had a vulnerability that was exploited by an unauthorized party. After Accellion informed us of the incident, Flagstar permanently discontinued use of this file sharing platform.

"Unfortunately, we have learned that the unauthorized party was able to access some of Flagstar’s information on the Accellion platform and that we are one of numerous Accellion clients who were impacted," Accellion warned in the security advisory.
