In March 2020, the Federal Bureau of Investigation's Boston office issued a warning about Zoom, telling users not to make meetings on the site public or share links widely after it received two reports of unidentified individuals invading school sessions. The service has come under fire over privacy and security issues, including incidents of 'Zoom bombing' in which uninvited users entered and disrupted meetings. 'We take meeting disruptions extremely seriously and, where appropriate, we work closely with law enforcement authorities.' The use of Zoom mushroomed during the COVID-19 pandemic.

What Zoom said 'We have been deeply upset to hear about these types of incidents, and Zoom strongly condemns such behavior,' Zoom spokesman Matt Nagel said in a statement. More than 220 participants were on the Zoom call at one point before it was terminated. Microphones and video were not muted by the organizer upon joining. A few minutes before the event was to start, one participant using the screen name 'Dan' began displaying graphic, pornographic images, according to a Reuters reporter on the call. The decision to cancel was made in consultation with the Fed after the intrusion. 'We have had various programs and this is something that we have never had happen to us.' He said that he suspects one of the security switches that mutes those watching an event was set incorrectly, but he was not sure of the details. It is an incident we deeply regret,' said Brent Tjarks, executive director of the Mid-Size Bank Coalition of America (MBCA), which hosted the event via a Zoom link.

'We were a victim of a teleconference or Zoom hijacking and we are trying to understand what we need to do going forward to prevent this from ever happening again. A virtual event with Federal Reserve Governor Christopher Waller was canceled earlier this month after the Zoom video conference was 'hijacked' by a participant who displayed pornographic images.
