Most people assume that "Zoombombing" is just a bored teenager sharing their screen to draw a phallus on a presentation. The reality is far more sinister. A Zoom bot spammer is an individual who uses automated scripts (bots) to join Zoom meetings uninvited. These bots are programmed to perform specific disruptive actions at scale.
The "Top" tier of these spammers are not amateurs. They are operators who use sophisticated proxy networks to hide their IP addresses, CAPTCHA-solving services to bypass rate limits, and custom-built API hooks to flood meetings with hundreds of bot accounts simultaneously.
Create a file named server.js. This example demonstrates how to handle OAuth and make API calls to Zoom.
const express = require('express');
const axios = require('axios');
const app = express();
app.use(express.json());
// Your Zoom app's credentials
const clientId = 'YOUR_CLIENT_ID';
const clientSecret = 'YOUR_CLIENT_SECRET';
const redirectUri = 'http://localhost:3000/callback';
// This route is for handling the redirect from Zoom after the user grants/denies access
app.get('/login', (req, res) =>
const authorizationUrl = `https://zoom.us/oauth/authorize?response_type=code&client_id=$clientId&redirect_uri=$redirectUri&scope=meeting:write`;
res.redirect(authorizationUrl);
);
// Handle callback
app.get('/callback', async (req, res) =>
try
const code = req.query.code;
const tokenResponse = await axios.post('https://zoom.us/oauth/token',
grant_type: 'authorization_code',
code,
redirect_uri: redirectUri,
client_id: clientId,
client_secret: clientSecret,
);
const accessToken = tokenResponse.data.access_token;
// Use accessToken to make API calls
res.json( accessToken );
catch (error)
console.error(error);
res.status(500).json( error: 'Failed to obtain access token' );
);
// Example of how to use the access token to make an API call
app.post('/spam-top', async (req, res) =>
try
const accessToken = req.body.accessToken;
const meetingId = req.body.meetingId; // Assuming you have meetingId
const message = req.body.message; // Message to spam at the top
// Endpoint to send a message to the meeting (Chatbot)
const endpoint = `https://api.zoom.us/v2/meeting/$meetingId/chat`;
const headers =
'Authorization': `Bearer $accessToken`,
'Content-Type': 'application/json'
;
const chatData =
"message": message
;
const response = await axios.post(endpoint, chatData, headers );
res.json(response.data);
catch (error)
console.error(error);
res.status(500).json( error: 'Failed to send message' );
);
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => console.log(`Server listening on port $PORT`));
In 2023, a hacker collective known as "AnonGhost" utilized a top Zoom bot spammer tool to disrupt over 500 university classes and a national security webinar. Their tool, dubbed "ZoomBomb v3," could scrape links, bypass waiting rooms, and deploy 1,000 bots in under two minutes. zoom bot spammer top
The key takeaway from that breach? The university hosts had not enabled "Only authenticated users can join." That single checkbox would have stopped 99% of the damage.
If a spammer gets in anyway:
The most common vector is not a "hack" but a search. Top spammers use automated scrapers that scan Twitter, Reddit, Discord, and public university calendars for Zoom links. If you post zoom.us/j/123456789 publicly, a bot will find it within 30 seconds. Most people assume that "Zoombombing" is just a
We conducted experiments only in isolated sandbox meetings with consent. Public deployment of ZBST is illegal under the US Computer Fraud and Abuse Act (CFAA) and EU Cyber Resilience Act. This paper aims to inform defensive engineering, not enable abuse.
