A hacking method by which an attacker obtains the password to a victim's account by answering the victim's security question (used to reveal the victim's password to himself in the event he forgets it), typically with information that is publicly available. So named because Paris Hilton's T-mobile account was compromised in this manner, as the attacker was able to answer her security question, "What is the name of your pet?" (Tinkerbell). Sarah Palin's Yahoo account was also compromised in this manner.
Don't answer security questions truthfully, as you could become the victim of a tinkerbell hack.
