Hackers stole personal data including Social Security numbers, addresses and account numbers of home mortgage holders at KeyBank, the bank reports, in the breach of a third-party vendor that serves multiple corporate clients.
The hackers obtained the information on July 5 after breaking into computers at the insurance services provider Overby-Seawell Company, according to a letter that Cleveland-based KeyBank sent to affected residential mortgage customers.
KeyBank, which operates in 15 states and has close to $200 billion in assets, would not say how many of its customers were affected or answer any other questions about the breach. In a statement, it said it was notified of the data theft on Aug. 4 and KeyBank systems and operations were unaffected.
