While some are bored in forced isolation, others work even more than usual. In the case of schools and universities, the organization of online conferences is also added to the tasks of preparing the educational or work process, at which it is necessary to collect all those involved and weed out unnecessary ones. And then users are suddenly faced with a new and unpleasant phenomenon - "zumba bombing".
The term comes from the name of the rapidly gaining popularity of the service for online conferences Zoom and the favorite joke in the USA “bombing” when outsiders crawl into other people's photos, videos, etc. In this case, "jokers" join other people's conferences without demand and do obscene things. So one troll sang obscene songs in an online lesson for elementary school students, and another mocked a meeting of Alcoholics Anonymous by tasting alcohol on the air.
The main problem of zumbombombing is the fundamental absence of methods of protection against such an intrusion. The Zoom service itself was designed just for the simplest possible connection, so that you can quickly and easily collect hundreds and thousands of people. In fact, you just need to enter the address https://zoom.us/j/xxxxxxxxx in your browser, where xxxxxxxxxx is the code of a specific conference. They are sent to the participants by the organizers themselves - but no one bothers the trolls to dial numbers at random and misbehave wherever necessary.
So far, the only countermeasure is the use of the "waiting room" mode, when the organizer can manually filter out unnecessary ones before the start of the conference. Experts have already called this a new cyber threat and vulnerability, because nothing prevents one corporation from sending a spy in the form of an inconspicuous clerk to another corporation's online conference to just sit and collect confidential information. By the way, US prosecutors have already made a statement that from the point of view of law, zumbombing is not a prank, but a crime, and in the event of a precedent it will be regarded accordingly.
