Haven’t heard of Zoom-bombing? Find out why the FBI has issued a warning | CBC News

Zoom has emerged as an indispensable video conferencing tool for remote work and study as millions of people  are forced to stay home during the COVID-19 pandemic. But a growing number of so-called Zoom-bombing incidents is prompting warnings from the FBI and from the victims themselves.

Dennis Johnson said he was in the middle of a video conference defending his doctoral dissertation — about the struggles of African Americans in California’s education system — when he started seeing profanity appear on the screen.

Then he saw letters spelling out the N-word.

Johnson says he froze. Seconds later, pornographic images began appearing all over the shared screen. Eventually, someone on the call was able to remove the uninvited culprit from the group.
