AmEx says it was notified by law enforcement that several large files containing some of its customers’ information was posted online. Consumers who may be impacted have already received a letter from AmEx explaining the incident. Affected individuals receive free identity theft assistance through American Express, which is offered to all cardholders, according to the notification letter. An AmEx spokeswoman says the leak is not the result of an AmEx breach or attack.”]
