This is considered the first attack over the Internet to cause physical harm. The hackers logged onto a site for those that suffer from epileptic seizures and changed the site to show flashing animations on the screen.

The group that is thought to have launched the attack is associated with anti-scientology attitudes. It is not clear why they would choose to take out their aggression on people suffering from epilepsy, but it was certainly misguided.

Just in case you are unsure what it means to suffer from the seizers (From Answers.com):

Pattern sensitive epilepsy is a form of reflex epilepsy precipitated by seeing certain patterns.

Photosensitive epilepsy is a form of epilepsy in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights, bold, regular patterns, or regular moving patterns.
