KeyBank mortgages hit by data breach: Names, social security numbers, and mortgage account information hacked

KeyBank mortgages have been hit by a data breach.

According to the latest information available from KeyBank the hackers obtained the first eight digits of social security numbers, as well as other information from a vendor.

Homeowners who have a mortgage through KeyBank may have had their names, addresses, and social security numbers obtained by hackers. The company says mortgage account numbers and property information may have also been included in the breach.

Since August, customers have been receiving letters in the mail informing them of the situation.

An unauthorized external party gained remove access in July to KeyBank’s data network. That network is maintained by the Overby-Seawell Company.

“OSC is investigating this incident with the assistance of third-party cybersecurity experts. They have deployed enhanced security monitoring tools across their network and notified the Federal Bureau of Investigation (FBI) of this incident,” the letter to customers reads.

It’s not clear at this point how many customers were impacted by the breach.
