The recent revelation of a significant security flaw within Zoom, a popular video conferencing platform, has sparked widespread concern and attention. This vulnerability, identified and reported by ethical hackers, exposed a critical gap in Zoom’s security, particularly affecting its Zoom Rooms service. The flaw could allow unauthorized access to private and corporate meetings, team chats, and a wealth of confidential information, posing a significant threat to the privacy and security of users worldwide.
This incident highlights the ever-present risks in our increasingly interconnected world and the constant battle between maintaining usability and ensuring security. It also underscores the importance of vigilant cybersecurity practices and the role of ethical hacking in uncovering potential threats. As we look at what happened in this incident, we aim to provide a comprehensive overview of the nature of the flaw, its implications for users and businesses, and the crucial steps Zoom took to mitigate this risk. For IT and security professionals, understanding this incident is not just about responding to a specific vulnerability; it’s about adapting to the daily challenges of digital security and fortifying defenses against evolving threats.
In this blog, we will guide you through the details of the Zoom account hijack flaw, its discovery, the potential avenues of exploitation, and the proactive measures needed to safeguard against such vulnerabilities – even if you don’t use Zoom. Our focus is to equip IT professionals with the knowledge and strategies necessary to protect their organizations and users in an environment where digital threats are an ever-changing reality.
AppOmni Offensive Security Engineer Ciarán Cotter first wrote about the details of the bug in a recent blog post. The post explains how he and his colleagues used the vulnerability to gain access to Zoom Rooms service accounts at the HackerOne H1-4420 event on June 22, 2023. Zoom sponsored the event and awarded bug bounty payouts to participating groups of white-hat hackers.

Companies using free email services such as Outlook or Gmail were particularly vulnerable to this bug. For instance, creating a Gmail account mirroring a Zoom Room’s generated email (like email@example.com) was straightforward and cost-free. This ease of duplication made it simple to discover and exploit a Zoom Room’s service email, accessible in meetings or via Team Chat.
Once inside the Zoom system, hijackers could join or host meetings, access contact lists, and infiltrate Team Chat and Whiteboard sessions. This breach posed a significant risk, potentially exposing sensitive internal communications, strategic plans, and financial details. AppOmni found that these compromised Room accounts couldn’t be ejected from Team Chat channels, even by administrators or the account Owner, amplifying the risk.
Following several conversations with the Zoom team with OppOmni, Zoom validated and promptly resolved the vulnerability in a recent software update. Zoom removed the ability to activate Zoom Room accounts to mitigate this vulnerability.
How Should IT Teams Take Proactive Steps?
In the wake of the Zoom account hijack vulnerability, IT teams must proactively safeguard their organization’s digital infrastructure. Here are vital steps that IT and security teams should consider implementing heading into 2024:
Regularly Update Software
Ensure all software, especially communication tools like Zoom, are updated with the latest security patches. These updates often contain fixes for known vulnerabilities.
Conduct regular training sessions for employees to recognize phishing attempts and other social engineering tactics that could compromise account security.
Implement Strong Authentication Protocols
Use strong, unique passwords for each service and enable two-factor authentication wherever possible to add an extra layer of security.
Monitor Account Activity
Set up systems to monitor unusual account activity, such as unexpected access from unfamiliar locations or devices, which could indicate a breach.
Review and Restrict Access Permissions
Regularly review who has access to what within your organization. Limiting access to sensitive information to only those who need it can reduce the risk of internal and external breaches.
Establish a Rapid Response Plan
Have a clear, well-practiced plan for responding to security incidents. This should include steps for containing the breach, assessing the damage, and communicating with affected parties.
Collaborate with Security Experts
Consider partnering with cybersecurity firms or ethical hackers to identify and address vulnerabilities in your systems before malicious actors can exploit them.
Audit and Assess Your Tools
Regularly audit your organization’s tools and software. Ensure they comply with your security standards and are not prone to known vulnerabilities.
By taking these proactive steps, IT teams can significantly reduce the risk of similar vulnerabilities and safeguard their organization’s digital assets and communications.
