The hack was discovered in the afternoon, the district said on its Facebook page. "Hate speech and graffiti was posted on all of our district websites and the system’s internal messenger was used to send emails to staff and some families," Kerry Birmingham, a district spokeswoman, told The Detroit News. "The language and images used were despicable, and we strongly denounce them." The incident also struck the International Academy in Troy, which said hackers "posted harmful and hurtful messages" on its website. Birmingham said preliminary information shows the hack "generated from outside the country using a known malicious IP address and that no student information or sensitive data was compromised by the breach."
