As video conference app Zoom surges in popularity due to increased usage amid the coronavirus pandemic, federal officials are now warning of a new potential privacy and security concern called “Zoombombing.”

The term refers to a form of cyber harassment reported by some app users, who have reported that some of their calls have been hijacked by unidentified individuals and trolls who spew hateful language or share graphic images.
