Hackers Post Johnston School Directory Online, Police Urge Calm and Caution
JOHNSTON, Iowa -- A group of overseas hackers have posted the Johnston school directory online including the name, grade level and address of thousands of students and their parents' phone numbers. The group "Dark Overlord" claimed credit on Twitter Thursday for hacking into Johnston school information and making text message threats to Johnston parents. Those threats lead the school district to cancel classes on Tuesday. Police now say none of the threats were credible.
