The system of an email provider for Disney Destinations was hacked into last week. The names of millions of customer and their emails were in Epsilon's system when the unauthorized access occurred last Wednesday.
Epsilon has said it is cooperating with authorities in this matter, and has not gone into detail on how exactly their system was hacked. The company also has sent emails on behalf of Disney Destination updating affected users on the breach.
Though Disney's system was not touched, a spokesperson for the company called the situation "disappointing."
