Law enforcement officials are investigating the incident where an email service provider selected to coordinate McDonald's promotional e-mails has had its computer systems compromised.
McDonald’s does not collect sensitive financial information, such as Social Security Numbers or credit card numbers on-line or through email. As such, the information improperly accessed did not include this type of information.
Rather, the information provided to McDonald’s included information required to contact users (such as name, mobile phone number, and postal address and/or e-mail address), and other general preference information.
In the event that you are contacted by someone claiming to be from McDonald’s asking for personal or financial information, do not respond. Remember, McDonald’s would not ask for that type of information online or through email.
