U.S. authorities are looking at whether a suspect charged with stealing data on more than 100 million Capital One customers from an Amazon.com Inc. cloud service successfully hit other targets.

On Wednesday, UniCredit said it had launched its own investigation into the matter after the bank's name was mentioned in a blog post by a cybersecurity researcher as a possible additional target of the Capital One breach.

Earlier on Thursday the New York State Department of Financial Services said it had been notified by Italy's biggest bank of the possible loss of consumer data related to the Capital One case.

A source close to the matter said UniCredit does not store any customer data on Amazon servers.
