Pictures and videos of the Turkish flag and a gun were put up on Eden Prairie High School's Web site by hackers Sunday.
Administrators found out about the attack and the site has since been disabled.
The viral attack stuck more than 100 websites globally, according to the school's Web page.
The hackers left other technology systems and Web sites affiliated with the school district alone.
The school district is going to keep Eden Prairie's Web site down until all issues have been taken care of.
