MOSCOW (Sputnik) — The CNN broadcaster reported that the hackers from the so-called Team System DZ group indicated in the pro-terrorist messages appearing on the websites that they were responsible for Sunday's cyberattack.
The attack targeted the website of Ohio Governor John Kasich, his wife Karen Kasich, the Ohio Department of Rehabilitation and Corrections and other online resources, the outlet added.
"All affected servers have been taken offline and we are investigating how these hackers were able to deface these websites. We also are working with law enforcement to better understand what happened," Tom Hoyt, spokesman for the Ohio Department of Administrative Services, said about the hacker attack as quoted by the broadcaster.
Ohio's local Federal Bureau of Investigation (FBI) office neither confirmed nor denied the involvement of Team System DZ in the attack, the broadcaster noted.
US government-related websites have experienced an increased number of cyberattacks over recent years. The 2016 report of the United States Government Accountability Office showed that since 2006, the annual number of cyberattacks on government websites rose by about 1,303 percent from 5,503 to 77,183 attacks.
