An Ohio school district is working with police to track down the person responsible for hacking a recent board meeting on Zoom to flash explicit images of child pornography during the conference call.

Brecksville-Broadview Heights School District Superintendent Joell Magyar sent an email to parents about the “heinous” ordeal Thursday night, which involved screenshots of “explicit sexual acts involving a minor,” WJW reports.

“We will find the individuals who selfishly, disgracefully and in the vilest manner possible exploited children and attempted to sabotage our meeting,” Magyar wrote.

“The BBHCSD will neither tolerate such a reprehensible exploitation of children, nor such a blatant attack on our public meetings.”

The superintendent warned parents that police will also come after anyone who shares screenshots of the images on social media.

“Please be advised that sharing child pornography is illegal and considered a felony,” Magyar wrote.

A total of 153 attendees were signed in, including children, when hackers displayed the “horrible illegal acts” for about 15 seconds toward the end of the meeting, WKYC reports.

“Police and federal law enforcement officers were contacted immediately, and a full investigation is being launched into the heinous act. Counselors will be available at the schools tomorrow, should any student who witnessed this horrific act need support,” Magyar wrote.

“In the immediate future, we are suspending all use of Zoom as a platform to deliver instruction. We will quickly research other safer platforms, and be in contact in the very near future as to other ways instruction will be delivered,” he wrote.

District officials are urging folks with any information about the hack to contact Brecksville or Broadview Heights police.

The incident is part of a broader pattern of public and private school Zoom meetings that have been hacked with racist or sexually explicit images in the weeks since schools shut down for the coronavirus.

In April, about 50 students on a call with Grovecrest Elementary School Principal Kyle Hoopes were exposed to porn for several seconds.

“It would be a good idea to talk with your children who may have heard or seen what was shared,” the school posted to Facebook, according to The Salt Lake Tribune.

It was the same situation in Clayton County, Georgia, and Lumberton, New Jersey, and Roseburg, Oregon, and Berkeley, California, and lots of other places.

The FBI warned about the “zoom bombings” in April and offered suggestions for preventing problems, and several districts in New York and New Jersey have banned educators from using Zoom software.

“As large numbers of people turn to video-teleconferencing (VTC) platforms to stay connected in the wake of the COVID-19 crisis, reports of VTC hijacking (also called zoom-bombing) are emerging nationwide,” the FBI Boston field office warned. “The FBI has received multiple reports of conferences being disrupted by pornographic and/or hate images and threatening language.”
