CLEVELAND, Ohio -- The Ohio governor's website was apparently hacked on Sunday, along with the state's prison system's website.

The official website for Ohio Gov. John Kasich showed the same message from the hacker on its homepage as did the Ohio Department of Rehabilitation and Corrections' website.

Several other state government websites were also apparently hacked, including the websites for: Ohio First Lady Karen Kasich, the Office of Workforce Transformation, the Casino Control Commission, Medicaid, the Office of Health Transformation, the state Inspector General, the Office of Facilities and Construction Commission and LeanOhio.

A message the hacking group, Team System Dz, left on both sites reads:

"Anti: Govt all word

You will be held accountable Trump, you and all your people for every drop of blood flowing in Muslim countries.

I love the Islamic state"

Those websites were taken offline on Sunday, shortly after the messages were discovered.

ODRC spokeswoman JoEllen Smith said in a statement that her agency is aware of the hack.

"We are aware of the situation and we are working aggressively to correct the situation," Smith's statement says. "A thorough investigation will be conducted to determine how this occurred and how it can be prevented in the future."

A spokeswoman for Kasich also did not immediately return messages.

Ohio Treasurer Josh Mandel posted a statement on his Facebook page regarding the hack.

"Wake up freedom-loving Americans. Radical Islam infiltrating the heartland," Mandel's statement says.

Team System Dz has claimed responsibility for hacking other governmental websites, including the Richland County Sheriff in Wisconsin and the Aberdeen City Council in Scotland, according to news reports.

They also appeared to have hacked the Brookhaven, Long Island website on Sunday, according to the New York Post. The same message appears on that website as of Sunday afternoon.
