The World Cup, Modern Stadiums, and the Cybersecurity Risks Fans Rarely See

When fans think about the World Cup, they think about goals, rivalries, and unforgettable moments. Security professionals think about something else entirely: how to safely manage hundreds of thousands of people moving through interconnected transportation systems, venues, communications networks, and digital platforms. In today’s environment, cybersecurity has become an essential part of that mission.

Beneath the excitement of cheering for our teams in these incredible venues is a quieter reality: modern sports venues are no longer just places to watch games. They are dense systems of data collection, digital access, surveillance, payments, communications, and crowd management. When something goes wrong with those systems, the consequences can extend far beyond the walls of the stadium.

A recent lawsuit, Avalos v. Madison Square Garden Entertainment Corporation (the “MSG lawsuit”), underscores this concern. The real risk is not limited to a single hack or temporary outage involving ticketing or payment systems. The broader concern is what happens when venues collect, track, store, and rely on large amounts of sensitive information about the people who walk through their doors.

The Cascading Effects of a Stadium Cyberattack

At first glance, a cyberattack on a stadium might sound limited: disrupted ticket sales, payment issues, or app outages. But those are only the surface-level impacts. The true result can be a long-term chain reaction affecting fans, employees, athletes, vendors, and the organization itself.

As the complaint in the MSG lawsuit alleges, the company stored not only basic personal and financial information, but also biometric facial recognition data and detailed internal profiles of attendees, according to Stadium Tech Report. When that kind of system is compromised, the damage multiplies:

• Personal and financial data can be used for identity theft. 
• Biometric data cannot be changed or replaced. 
• Internal tracking data can expose behavioral or reputational information. 
• Once stolen, that data can circulate for years, extending the harm far beyond a single event.

The concern is not just that information may be stolen. It is that compromised data can create new risks in unrelated systems. For example, biometric information used for stadium access could potentially be misused in other environments that rely on facial recognition or identity verification. What begins as a venue cybersecurity incident can quickly become a broader privacy, safety, and identity-management problem.

Why Sports and Entertainment Venues’ Face Unique Cyber Exposure

Major events like the World Cup, NBA Finals, Super Bowl or Olympics carry heightened cyber risk. Stadiums bring together:

• Massive crowds, often in the tens of thousands per event;
• Multiple overlapping systems, such as ticketing, payments, access control, surveillance, communications, and emergency operations; and
• Increasing use of real-time monitoring, analytics, and biometric technologies.

The incident that led to the MSG lawsuit reportedly involved systems containing identifiable data for more than 26 million individuals, including biometric data from facial scans, threat assessment profiles, and contact information for players.¹ When those systems are breached, the impact reaches beyond one-off transactions and into long-term privacy, security, and public safety concerns.

A cyber incident during a major sporting event could also have immediate operational consequences.

• If ticketing or access control systems fail, thousands of people could be left waiting outside in bad weather or unsafe conditions. 
• If internal player or security information is exposed, it could create safety concerns for athletes, staff, or high-profile attendees. 
• If communication systems are disrupted, venue operators may struggle to coordinate security, emergency response, or crowd movement.

In that moment, cybersecurity is no longer just an IT issue. It becomes a public safety issue.

What Fans Can Do to Protect Themselves at Stadiums and Events

Individuals have limited control over how venues operate. Realistically, few fans are likely to skip the big game because of data privacy concerns. But they can still reduce their exposure.

Practical steps fans can take:

1. Be mindful of how much personal information is shared when purchasing tickets or using venue apps.
2. Use strong, unique passwords for ticketing platforms.
3. Monitor financial accounts and credit activity regularly.
4. Consider placing fraud alerts or credit freezes if a breach is reported involving a stadium, team, ticketing platform, or venue app they have used.

Even those simple actions create a basic level of awareness that matters and can help individuals proactively protect their data.

How Stadiums and Venue Operators Should Prepare for Cyber Threats

For stadiums, teams, leagues, and entertainment venues, preparation cannot begin after a breach occurs. These organizations operate complex environments where cybersecurity, privacy, business continuity, physical security, and public safety are increasingly connected. Preparation should focus on reducing risk at the source and understanding how one failure could cascade across the entire event ecosystem.

Five steps every venue and event operator should take:

1. Limit data collection to what is necessary.
2. Treat biometric data as especially sensitive and restrict its use.
3. Separate data systems where possible to avoid large, centralized targets.
4. Respond to data breaches quickly with clear and honest communication.
5. Build a cybersecurity incident response plan including conducting tabletop exercises that test more than traditional data breach response.

These exercises should also examine cascading impacts, such as:

• Crowd delays because of a ticketing issue during severe weather
• Loss of access control systems
• Exposed player or security information
• Disruption to emergency communications
• Misuse of biometric information in unrelated systems.

Beyond following guidelines, venues must prioritize proactive prevention as access to and collection of data continue to grow. Organizations should work with cybersecurity, privacy, physical security, and emergency management experts to test systems, identify weaknesses, and practice response before a major event places those systems under pressure.

The Bigger Picture: Cybersecurity Is the New Foundation of the Fan Experience

The World Cup reminds us that modern sporting events are no longer just games. They are global, connected, data-rich operations involving millions of people and countless digital touchpoints. Protecting those environments requires more than securing a network. It requires understanding how a single cyber incident can ripple outward, affecting privacy, operations, public safety, trust, and the fan experience itself.

Because at the end of the day, the goal is simple: great games, safe fans, and no one having to explain a cybersecurity incident in the post-game press conference.
