Here's a Hacker Attack That Will Make You Grind Your Teeth

As if going to the dentist wasn't painful enough.

A dental practice was hit last year by a strain of malicious software that sought out X-ray images and encrypted them on the clinic's computer system.

The ransom amount increased by $500 each day it wasn't paid.
