KeyCorp has notified customers in Ohio and other states that private information about them was taken when a laptop computer was stolen from an outside vendor.
Officials say the information on 9,300 customers may include Social Security Numbers. Corporate communications for the Cleveland-based bank say affected customers were notified by mail.
Key hired the unnamed vendor to scan paper documents into a computer format for storage. Officials say the vendor violated its contract by putting the data on a laptop computer that was taken outside of its offices and failing to encrypt sensitive information. They say that vendor has since been fired.
The bank has offered to provide affected customers a year of free credit monitoring, and credit repair in the event someone tries to use the stolen information.
