The rapid global adoption of Zoom as a primary teleconferencing platform has inadvertently created a lucrative attack surface for automated disruption. This paper introduces and analyzes Zoom Bot Spammer Top (ZBST), a novel class of distributed bots designed to infiltrate unsecured or publicly listed Zoom meetings. Unlike prior "Zoombombing" incidents reliant on manual human entry, ZBST leverages headless browser automation, machine learning-generated audio/text payloads, and token prediction algorithms. We reverse-engineer its command-and-control (C2) infrastructure, categorize five distinct spam payload types (audio deepfakes, text flood, screen-share malware bait, and emotive manipulation), and evaluate current defensive mechanisms (waiting rooms, keyword filters, CAPTCHA). Our findings show that ZBST can bypass 73% of default free-tier protections within 42 seconds. We conclude with a multi-layered detection framework using entropy-based traffic analysis and audio fingerprinting.
The "Top" level of spamming involves compromised accounts. Spammers purchase stolen Zoom credentials (email/password) from dark web marketplaces like the Russian Market or Genesis. They then use these legitimate accounts to launch spam from within your organization, making it impossible to distinguish a bot from a colleague.
If a spammer gets in anyway:
Some advanced spammers bypass the need for a password by exploiting older versions of the Zoom client or leaked JWT (JSON Web Token) secrets. While Zoom has patched many of these, legacy enterprise accounts sometimes remain vulnerable, allowing bots to impersonate legitimate users.
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.
The Zoom bot spammer top tier is not a myth; it is an organized nuisance industry. They are lazy. They rely on hosts who leave doors open. They scan for the path of least resistance.
If you implement the five steps above—authentication, waiting rooms, host-only shares, and disabling join-before-host—you will become a hard target. The spammers will skip your meeting and move on to an easier victim.
Remember: Security is not a feature; it is a setting. Review your Zoom privacy settings today, or prepare to get spammed.

Creating a feature for a Zoom bot to spam the top of a meeting can be approached in several ways, depending on the platform (e.g., web, mobile) and the programming language you're using. Zoom bots can be developed using Zoom's API, specifically the Zoom Webhooks and APIs which allow for a variety of functionalities.
Below is a conceptual guide on how to create a basic feature for a Zoom bot to spam the top of a meeting. This guide assumes you are familiar with Node.js and JavaScript, as well as Zoom's API.
This example provides a basic structure. Implementing a fully functional Zoom bot with spamming capabilities at the top of a meeting involves handling various Zoom API nuances and edge cases, which may require diving deeper into Zoom's documentation and experimenting with their APIs.
Creating or using bots to disrupt Zoom meetings—often called "Zoom bombing" or "meeting flooding"—violates terms of service and can have legal consequences. However, if you are a host looking to protect your meetings or a developer looking to build legitimate automation
, here is an overview of how these bots work and how to stop them. What is a Zoom Spammer Bot?
A Zoom spammer bot is an automated program designed to join meetings and send a high volume of unsolicited messages or media.
: These bots often use multiple instances to join a single meeting, overwhelming the chat or audio. Automation Tools : Developers sometimes use libraries like to automate keystrokes (like typing messages) or the Zoom Meeting SDK for more advanced interactions.
: Using such bots can lead to account suspension, IP bans, or legal action depending on local laws regarding digital harassment. How to Protect Your Meetings from Bots
To prevent bot-driven spam and unauthorized access, hosts should use Zoom's built-in security features: Waiting Rooms : Enable the Waiting Room feature to manually admit each participant. : Never share meeting links publicly without a passcode. Restrict Chat
: In the "Security" icon during a meeting, you can uncheck "Chat" to prevent anyone from sending messages. Lock Meeting zoom bot spammer top
: Once all expected guests have arrived, use the "Lock Meeting" option to prevent new participants (including bots) from joining. Block AI Bots : Admins can disable the AI Companion's ability to join third-party meetings
if they want to prevent automated note-takers from entering. Legitimate Alternatives for Automation
If your goal is to automate tasks like note-taking or meeting recording without spamming, consider these official methods:
The Rise of Zoom Bot Spammers: A Growing Concern
In recent times, the popular video conferencing platform Zoom has been facing a new challenge: bot spammers. These automated programs have been flooding Zoom meetings with unwanted messages, disrupting online gatherings and causing frustration among users.
What are Zoom Bot Spammers?
Zoom bot spammers are automated programs designed to infiltrate Zoom meetings and send spam messages, often with malicious intent. These bots can be programmed to join meetings, send messages, and even share unwanted content, such as links or images.
How Do Zoom Bot Spammers Work?
Zoom bot spammers typically work by using Zoom's API (Application Programming Interface) to join meetings and send messages. They can be programmed to target specific meetings, using techniques such as:

Below is a synthesis of key findings from leading research papers and technical reports regarding the mechanics, motivations, and mitigation strategies for Zoom bot spammers. 1. The Anatomy of Zoom Bot Attacks
Research categorizes these disruptions into a four-stage process known as the Zoombombing Lifecycle Reconnaissance:
Attackers find public meeting links and passwords on social media (e.g., X, Discord, Reddit) where hosts have neglected security measures. Coordination:
Malicious actors aggregate on threads to share specific access details and personal information about the host.
Using scripts (often Python-based with Selenium), automated bots join the meeting to "flood" it with spam messages, offensive images, or audio disruptions.
The ultimate goal is to cause psychological distress or shut down the meeting entirely. 2. Detection and Identification Challenges
Identifying and stopping these bots in real-time is difficult for several reasons identified by the ACM Digital Library Intruder Identification:
In large, crowded public meetings, it is hard for hosts to distinguish between a legitimate attendee and a bot until the disruption starts. Phishing and Social Engineering: Spammers often use "lookalike" domains (e.g., vs. the official ) to trick users into providing credentials. Automated Registration:
Bots have been observed signing up for webinars and meetings using suspicious domains (e.g., @schoolmail.website ) to bypass initial vetting. 3. Recommended Mitigation Strategies
Experts recommend a multi-layered defense to prevent bot-driven spam: Use the Waiting Room:
Always enable the Waiting Room to manually admit participants, which serves as a primary barrier against automated entry. Password Complexity:
Avoid using easily guessed passwords or posting them publicly. Restrict Permissions:
Lock "Screen Sharing" and "Chat" for participants unless they are specifically needed. Reporting Tools: report participants as spam
directly within the meeting interface to help Zoom’s safety team identify malicious accounts. Notable Research Papers

This write-up provides an overview of Zoom bot spammers, detailing how they function, the risks they pose, and the best practices for preventing them from disrupting your meetings. What is a Zoom Bot Spammer?
A Zoom bot spammer is an automated program or script designed to join Zoom meetings—often without an invitation—to flood the chat, audio, or video with unsolicited and disruptive content. These bots typically leverage simple automation libraries like PyAutoGUI or more complex frameworks to simulate human interaction. Common Methods of Operation
Meeting Scraping: Spammers use tools to crawl public websites, social media, and forums to find unprotected Zoom links.
Credential Stuffing: Bots may attempt to guess meeting IDs or use leaked passwords to gain entry.
Macro Automation: Some basic bots use Python scripts to type and send messages at high speeds, effectively "flooding" the chat.
Account Injection: More advanced bots may create fake user accounts to bypass initial filters. Security Risks and Impact
Meeting Disruptions: Constant spamming can make it impossible for legitimate participants to communicate or follow the agenda.
Privacy Violations: Some malicious bots are used to record meetings or "steal" intellectual property from presenters.
Phishing & Malware: Bots often post links in the chat that lead to phishing sites or malware downloads. How to Prevent and Stop Bot Spam
