Introduction
A law firm’s senior partner was midway through a confidential client strategy session when an unknown participant suddenly appeared in the video call. Before anyone could react, the intruder started screen sharing—displaying the firm’s own confidential case documents they had somehow accessed.
The meeting descended into chaos. How did they get in? What else had they accessed? Were they recording? The firm’s managing partner later told me this five-minute security breach led to a malpractice claim, loss of the client, and regulatory investigation that cost them over $800,000.
Here’s the terrifying part: This wasn’t a sophisticated nation-state attack. It was a disgruntled former employee who simply guessed the meeting link pattern the firm used predictably for all client meetings.
I’ve investigated dozens of video conferencing security incidents over the past few years. The pattern is always the same: Organizations assume their meetings are secure because they’re using “enterprise” platforms. Then something goes wrong—catastrophically wrong—and they discover their meetings were never actually protected.
A healthcare provider conducting telemedicine appointments had patient consultations intercepted by strangers who joined meetings without being challenged. HIPAA violations, patient privacy breaches, regulatory fines exceeding $1.2 million.
A technology startup pitching to investors had their product demo hijacked by someone who shared pornographic content to everyone in the meeting. The investors left. The funding round collapsed.
A government contractor discussing classified projects discovered recordings of their meetings had been posted online. Security clearances were revoked. The contract was terminated.
These aren’t rare edge cases—they’re increasingly common video conferencing security threats that every organization faces. The question isn’t whether your meetings could be attacked. It’s whether you’ll discover vulnerabilities through a drill or through disaster.
This guide reveals the five most dangerous security threats to your online meetings—and more importantly, the specific fixes that actually protect you. Let’s start with the threat that’s easiest to exploit and most commonly ignored.
Threat 1: Unauthorized Meeting Access (Meeting Hijacking)
Remember when everyone suddenly started talking about “Zoombombing”? That viral moment revealed a problem that’s actually far worse than most people realize.
Why This Threat Matters
Imagine holding a confidential board meeting about a pending merger. Someone who wasn’t invited joins the call, listens to strategic discussions worth millions, then leaks that information to competitors or the press.
This isn’t hypothetical. A financial services firm conducting earnings preview discussions had an unauthorized participant join their leadership call. Within hours, market analysts were asking questions about information that should have been confidential for another week. The stock moved. The SEC investigated.
The attack is shockingly simple: Attackers find or guess meeting links, join without authorization, then listen, record, disrupt, or steal information.
How Attacks Happen
Predictable meeting links: Many platforms generate meeting IDs sequentially or with predictable patterns. Attackers simply try variations until they find active meetings.
Shared links on social media: Someone innocently tweets “Join our webinar!” with the meeting link. Now it’s public.
Recycled meeting links: Using the same meeting link repeatedly means anyone who ever had access can join anytime.
No authentication required: Platforms that let anyone join without verifying identity make attacks trivial.
Forwarded invitations: An invited participant forwards the meeting link to someone who shouldn’t attend.
Real-World Impact
A consulting firm lost a $2 million client after a competitor somehow joined their strategy presentation to that client. The competitor had clearly heard the pitch—they submitted a proposal addressing specific points that were only discussed in the “private” meeting.
An elementary school had strangers join virtual classrooms and harass children. Parents removed kids from the school. The principal resigned. The district faced lawsuits.
A pharmaceutical company had their drug development meeting infiltrated by someone who recorded presentations about unreleased clinical trial data—then tried to blackmail the company.
The Fixes That Actually Work
- Use unique, random meeting IDs for every meeting. Never use predictable patterns or sequential numbers. Each meeting should have a cryptographically random identifier that can’t be guessed.
- Require meeting passwords—always. Don’t make passwords optional. Every meeting should require a password that’s different from the meeting ID and not shared publicly.
- Enable waiting rooms. Hosts should manually admit each participant after verifying their identity. This single control prevents virtually all unauthorized access.
- Use registration for webinars and public events. Collect participant information before granting access. Verify email addresses. Create unique access links for each registrant.
- Implement SSO and authentication. For internal meetings, require participants to authenticate through your organization’s identity provider. No external access without proper verification.
- Lock meetings once everyone has joined. Prevent additional people from joining after the meeting starts. If someone legitimate is late, they can request access and be manually admitted.
- Monitor participant lists actively. Regularly review who’s in your meeting. Remove anyone who shouldn’t be there immediately.
- Convay’s approach: Every meeting uses cryptographically random IDs. Waiting rooms are enabled by default. Host controls make removing unauthorized participants instantaneous. Authentication integrates with enterprise identity systems to verify every participant automatically.
Threat 2: Data Interception and Eavesdropping
Your video call looks secure on your screen. But what’s actually happening to your data as it travels across the internet?
Why This Threat Matters
A defense contractor discussed classified project details in what they thought was a “secure” video call. Later, intelligence reports suggested foreign actors had detailed knowledge of information only discussed in that meeting.
How did classified information leak? The video platform used basic transport encryption—protecting data from casual interception but not from sophisticated adversaries with access to network infrastructure.
When your data isn’t properly encrypted end-to-end, it’s vulnerable at multiple points: On your network, at your internet provider, on the platform’s servers, at recipient networks. Each point is a potential interception opportunity.
How Attacks Happen
- Unencrypted connections: Some platforms still allow unencrypted connections. Your video and audio travel across the internet in plaintext—readable by anyone intercepting traffic.
- Weak encryption: Platforms using outdated encryption standards (DES, RC4, or older TLS versions) provide a false sense of security. Modern attackers break these easily.
- Man-in-the-middle attacks: Attackers position themselves between you and the platform, intercepting and potentially modifying data in transit.
- Compromised networks: Public Wi-Fi, hotel networks, or compromised corporate networks give attackers direct access to your traffic.
- Platform-side decryption: Even with transport encryption, platforms that decrypt your data on their servers create vulnerability. Anyone accessing those servers accesses your unencrypted meetings.
Real-World Impact
A law firm conducting international arbitration discovered their opponent seemed to know their strategy before they presented it. Forensic investigation suggested their video calls had been intercepted through compromised hotel Wi-Fi during international travel.
A technology company’s product development meetings were somehow leaked to competitors. Investigation traced it to an employee joining meetings from coffee shops on public Wi-Fi—where traffic interception is trivial.
A healthcare provider’s telemedicine platform was breached. Patient consultation recordings were accessed because the platform stored them with weak encryption using keys that were compromised.
The Fixes That Actually Work
Use only platforms with end-to-end encryption. Data should be encrypted on your device, stay encrypted throughout transmission, and only be decrypted by intended recipients. The platform should never have access to unencrypted data.
Verify encryption implementation. Don’t just trust marketing claims. Review third-party security audits. Understand exactly what “encrypted” means for your platform.
Avoid public Wi-Fi for sensitive meetings. If you must use public networks, connect through a VPN that adds an additional encryption layer.
Use strong authentication. Even encrypted data is vulnerable if attackers can authenticate as legitimate users. Multi-factor authentication prevents credential compromise.
Regularly update software. Encryption vulnerabilities are discovered regularly. Keeping your software updated ensures you have the latest security patches.
Monitor for suspicious activity. Unusual connection patterns, unexpected geographic locations, or irregular access times can indicate compromised accounts.
Educate users about phishing. Many interception attacks start with stolen credentials from phishing emails. Users who recognize phishing attempts prevent most credential theft.
Convay’s approach: True end-to-end encryption where Convay’s servers never access unencrypted meeting data. All encryption happens on participant devices using cryptographically strong algorithms. Third-party audited implementation ensures encryption actually works as promised.
Threat 3: Recording and Screen Sharing Abuse
Recording and screen sharing are essential features—until someone uses them maliciously.
Why This Threat Matters
A human resources manager conducted termination meetings via video, following the company’s remote work policy. An employee being terminated secretly recorded the entire conversation—then edited clips out of context to make it appear discriminatory. The resulting lawsuit cost the company $450,000 in settlement plus legal fees.
The problem: Legitimate meeting features become weapons when misused. Unauthorized recordings violate privacy and create legal liability. Malicious screen sharing can expose confidential information or distribute inappropriate content.
How Attacks Happen
Unauthorized local recordings: Participants record meetings using device screen capture tools—even when platform recording is disabled.
Stolen cloud recordings: Hackers access platform accounts and download stored meeting recordings containing confidential discussions.
Malicious screen sharing: Attackers share inappropriate, offensive, or confidential content that disrupts meetings and potentially violates laws.
Shared recordings distributed widely: Someone records a meeting, then shares it publicly or with unauthorized parties—violating confidentiality.
Screenshots of confidential content: Even without recording, participants capture screenshots of sensitive presentations or discussions.
Real-World Impact
A board meeting discussing executive compensation was secretly recorded by an administrative assistant who had access but wasn’t supposed to record. The recording was leaked to media, causing embarrassment and trust issues.
A school’s faculty meeting was recorded without consent and posted online. Teachers discussing individual students (educational purposes) suddenly became public—violating student privacy laws and resulting in firings.
A startup’s product demo meeting had someone screen share pornographic content. Investors were present. The funding round collapsed. The company folded three months later.
The Fixes That Actually Work
- Control recording permissions granularly. Don’t give everyone recording rights. Designate specific roles or individuals authorized to record. Require approval for all recordings.
- Notify participants when recording starts. Legal requirements in many jurisdictions mandate disclosure. Beyond legal compliance, transparency builds trust and prevents unauthorized recording from being claimed as secret.
- Watermark recordings with participant information. If recordings leak, watermarks identify the source. This accountability deters most unauthorized distribution.
- Control screen sharing permissions. Don’t allow all participants to screen share freely in large meetings. Require approval or limit screen sharing to specific roles.
- Implement host controls for immediate response. Hosts should be able to immediately stop malicious screen sharing, remove disruptive participants, and end meetings if attacks escalate.
- Store recordings securely with access controls. Cloud recordings should be encrypted, access-controlled, and audited. Not everyone who attended should automatically access recordings forever.
- Train users on acceptable use policies. Make clear what’s permitted and what’s prohibited. Outline consequences for policy violations.
- Monitor for unauthorized recording tools. Some platforms can detect when participants run screen recording software—alerting hosts to potential unauthorized recording.
- Convay’s approach: Granular recording controls with role-based permissions. Automatic participant notification when recording begins. Host controls for immediate response to abuse. Recordings stored with encryption and detailed access controls. Audit logs tracking who accessed recordings and when.
Threat 4: Weak Authentication and Account Compromise
Your video platform is only as secure as your login credentials. Weak authentication is the front door attackers use to access everything else.
Why This Threat Matters
A pharmaceutical company’s research director had his video platform account compromised through a phishing email. Attackers gained access to months of recorded drug development meetings containing proprietary research worth hundreds of millions.
The breach happened because: The platform used only password authentication. The password was reused from another site that had been breached. No multi-factor authentication blocked the unauthorized access.
When accounts are compromised, attackers don’t just access past recordings—they can join future meetings, impersonate legitimate users, and maintain persistent access to confidential communications.
How Attacks Happen
Weak passwords: Users choose simple, easily guessed passwords that attackers crack through brute force or dictionary attacks.
Password reuse: Same password used across multiple sites means a breach on one site compromises all accounts.
Phishing attacks: Fake login pages trick users into revealing credentials.
Credential stuffing: Attackers use lists of compromised credentials from other breaches to attempt login on your platform.
No multi-factor authentication: Accounts protected only by passwords are vulnerable once passwords are compromised.
Abandoned accounts: Former employees whose accounts weren’t deactivated maintain access long after leaving.
Real-World Impact
A marketing director received an email appearing to be from their video platform requesting login for “security verification.” They entered credentials. Within hours, confidential client pitch recordings were accessed and shared with competitors.
A hospital’s telemedicine platform had multiple physician accounts compromised through credential stuffing. Attackers accessed patient consultation recordings—triggering HIPAA violations and a $2.8 million fine.
A law firm partner’s account was compromised. The attacker joined meetings, listened to confidential client discussions, then attempted to blackmail clients with information only discussed in supposedly private meetings.
The Fixes That Actually Work
Mandate multi-factor authentication for all users. Require something you know (password) plus something you have (phone, security key) for all account access.
Integrate with enterprise SSO. Use your organization’s identity provider (Azure AD, Okta) for centralized authentication management. When employees leave, access is revoked across all systems simultaneously.
Enforce strong password policies. Require minimum length (12+ characters), complexity (mixed case, numbers, symbols), and regular updates.
Implement account monitoring and alerts. Notify users of unusual login patterns—unfamiliar locations, impossible travel times, unusual access hours.
Use security keys for high-risk users. Executives, financial personnel, and anyone accessing sensitive information should use hardware security keys resistant to phishing.
Promptly deactivate accounts for departed employees. Immediate deactivation prevents former employees from accessing meetings or recordings.
Limit login attempts and implement lockouts. After several failed login attempts, temporarily lock accounts to prevent brute force attacks.
Educate users about phishing recognition. Regular training helps users identify fake login pages and suspicious emails requesting credentials.
Convay’s approach: Multi-factor authentication required by default. Enterprise SSO integration for centralized identity management. Comprehensive account monitoring with alerts for suspicious activity. Automatic lockouts after failed login attempts. Regular security awareness training for users.
Threat 5: Insider Threats and Privilege Abuse
Sometimes the threat isn’t external hackers—it’s people who already have access abusing their privileges.
Why This Threat Matters
A disgruntled IT administrator at a legal firm downloaded recordings of hundreds of client meetings before being terminated. He attempted to sell confidential case information to opposing counsel in active litigations.
The problem: Users with legitimate access sometimes misuse that access—whether maliciously or accidentally. Privileged administrators can access everything. Participants can record and distribute confidential content. Employees leaving can take sensitive information with them.
How Attacks Happen
- Over-privileged accounts: Users granted more access than they need for their role can access meetings and recordings they shouldn’t see.
- Administrative abuse: Platform administrators with broad access can potentially view or download any meeting recording.
- Data exfiltration before departure: Employees planning to leave download meeting recordings and content to take to competitors.
- Accidental exposure: Well-meaning employees share meeting recordings with unauthorized people, not understanding confidentiality requirements.
- Lack of accountability: Without audit logging, insider threats operate undetected until damage is discovered much later.
Real-World Impact
A sales executive joining a competitor downloaded all recordings of client meetings, product demos, and strategic planning sessions from the past year—giving his new employer detailed competitive intelligence.
A healthcare system administrator accessed patient consultation recordings out of curiosity—HIPAA violation that resulted in termination, $50,000 fine, and criminal charges.
An assistant with meeting scheduling access forwarded a board meeting link to a friend who was a reporter. The resulting leaked board discussion about layoffs created panic and operational disruption.
The Fixes That Actually Work
- Implement least-privilege access controls. Users should only access meetings and recordings directly relevant to their role. Default should be no access unless specifically granted.
- Use role-based permissions. Define roles with appropriate access levels. Assign users to roles rather than granting individual permissions case-by-case.
- Comprehensive audit logging. Track every action—who accessed which recordings, who joined which meetings, who downloaded what content. Logs should be tamper-proof and regularly reviewed.
- Implement data loss prevention. Monitor for unusual download patterns, mass recording access, or suspicious data movement.
- Require approvals for sensitive meeting access. High-sensitivity meetings should require explicit approval before users can access recordings.
- Regular access reviews. Quarterly audits of who has access to what—removing unnecessary permissions and ensuring access matches current roles.
- Exit procedures for departing employees. Immediate access revocation upon resignation or termination. Review of access logs to identify any suspicious activity before departure.
- Separation of duties. Platform administrators shouldn’t automatically access meeting content. Separate administrative functions from content access.
- Convay’s approach: Granular role-based access controls with least-privilege defaults. Comprehensive tamper-proof audit logging. Data loss prevention monitoring. Automated access reviews identifying over-privileged accounts. Integration with HR systems for immediate access revocation upon employee status changes.

Conclusion: Security Isn’t Optional
Here’s the hard truth: Every video meeting is a potential security incident waiting to happen. The question isn’t whether your organization faces these threats—it’s whether you’ll address them proactively or reactively.
Reactive approaches cost millions in fines, lawsuits, lost business, and destroyed reputation. Organizations that discover security gaps through breaches pay catastrophically.
Proactive approaches cost far less and prevent disasters before they happen. Organizations that implement proper security controls avoid the catastrophic incidents that make headlines.
Convay was built for organizations that understand security can’t be an afterthought—it must be foundational. Every feature, every capability, every design decision prioritizes protecting your communications.
The five threats in this guide aren’t theoretical possibilities—they’re daily realities. The fixes aren’t optional recommendations—they’re essential protections.
Your next meeting could be the one that’s attacked. Are you protected?
