Coffee and donut lovers Dunkin' says, if you use their DD Perks program, there's a chance your personal information may have been compromised in a recent security breach.
Dunkin Brands says it learned from a security vendor that on Halloween -- hackers tried to get access to some DD-Perks accounts online.
While several of those attempts were blocked -- any successful attacks may have exposed customer names, email addresses, and DD perk account numbers.
Dunks says any affected users will be assigned replacement account numbers.
If your DD Perks info was hacked, Dunkin' will force a password reset. If you've used this password for other online accounts, you're advised to change those passwords.
