It's likely a Hilton problem. Someone hacked into your HHonors account. They then set up a brand new Amazon account, and linked that Amazon account with your hacked HHonors account. They then bought some stuff on Amazon, and used your HHonors points to pay for the stuff. Amazon wouldn't have seen anything unusual on your Amazon account because your Amazon account wasn't used to steal your points.
