The US Federal Bureau of Investigation (FBI) warned today of hijackers who join Zoom video conferences used for online lessons and business meetings with the end goal of disrupting them or for pulling pranks that could be later shared on social media platforms.

"The FBI has received multiple reports of conferences being disrupted by pornographic and/or hate images and threatening language," the warning published by FBI's Boston Division says.
