McDonald's has confirmed today that hackers broke into a database containing email addresses and birthdays for consumers who have signed up for McDonald's promotions.
"The incident has resulted in an investigation by law enforcement authorities. Arc and McDonald's are cooperating with the appropriate authorities," says spokeswoman Danya Proud. "We are also working with Arc and their database management firm to understand how the security was bypassed."
Arc refers to long-time McDonald's business partner Arc Worldwide, an email database management firm.
It is unclear how many consumers are affected.
