McDonald’s customers’ data exposed in a Big Mac hack attack

McDonald's has alerted a number of its customers that their personal details might have been compromised, following a hacking exploit in the US.In a letter sent to those believed to have been affected, McDonald's said that no financial details were exposed.The letter said, "McDonald's does not collect sensitive financial information, such as social security numbers or credit card numbers online or through email. As such, the information improperly accessed did not include this type of information."It did, however, include information required to confirm age, a method of contact, such as name, mobile phone number, postal address and email address, along with other general preference information. The hack came as US online media business Gawker suffered the internet security warning to its customers following a spate of phishing emails claiming to come from the brand.
