England’s 4-2 win over Croatia on Tuesday night offered an early reminder that goals are rarely in short supply at a World Cup. Yet as fans celebrate the action on the pitch, security teams across the US, Canada, and Mexico are focused on a different challenge: protecting the vast network of connected infrastructure that keeps the tournament running.
From smart turnstiles and digital ticketing systems to CCTV networks, building management platforms, stadium-wide communications infrastructure and even a smart ball, the 2026 FIFA World Cup is as much a technological undertaking as a sporting spectacle.
Organisers must not only deliver matches across three countries and 16 host cities, but also safeguard the interconnected systems that enable millions of supporters to move through venues, access services, and stay connected.
Modern stadiums increasingly resemble connected industrial environments, combining lighting controls, environmental management systems, digital signage, access-control technologies, surveillance infrastructure, and communications networks into a single operational ecosystem.
“World Cup host cities are currently welcoming millions of people, including players, officials, game sponsors, and media personnel,” says Cynthia Overby, Director of Strategic Security Solutions at Rocket Software. “With many relying heavily on connected devices and public networks, the tournament is creating an unmissable opportunity for cybercriminals to exploit.”
Overby says organisations must adopt a layered security strategy that extends beyond traditional network defences. This includes isolating operational technology such as stadium lighting, HVAC systems, and digital signage from corporate IT environments and public-facing networks.
The scale of the challenge is amplified by the size of the tournament. Expanded to 48 teams for the first time, the 2026 competition spans multiple jurisdictions, dozens of venues, and millions of visitors. Each host city relies on a complex web of technology providers, telecommunications networks, transport operators, broadcasters, payment platforms, and third-party contractors.
That growing interconnectedness is creating what security experts describe as an unprecedented attack surface.
“This is the largest World Cup ever staged but also an attack surface,” says Kevin Curran, Professor of Cybersecurity at Ulster University and Senior IEEE Member. “Every ticketing system, official app, streaming service, accreditation database, stadium network and sponsor platform is another door that someone must keep locked for its duration.”
“What makes 2026 different is not the criminals’ ambition but their tooling,” says Curran. “Generative AI has lowered the cost of deception.”
Researchers are already observing increasingly sophisticated activity linked to the tournament. Threat intelligence firm CloudSEK recently identified a network of cloned FIFA ticketing sites capable of harvesting payment card details and intercepting one-time passwords.
“This campaign shows how major global events are being weaponised by organised cybercriminal groups,” says Gagan Aggarwal, Threat Intelligence Researcher at CloudSEK TRIAD. “We are now seeing full checkout impersonation, live victim tracking, card skimming and OTP interception capabilities being combined into one operational platform.”
Although such campaigns primarily target supporters, they underline the level of investment threat actors are prepared to make around globally significant events.
Mobile devices represent another critical area of concern. Supporters increasingly rely on smartphones for tickets, payments, navigation, transport information, and event services, creating additional opportunities for attackers.
“Events like the World Cup are no longer just physical or network security challenges; they are mobile security stress tests,” says Kern Smith, Vice President of Global Solutions Engineering at mobile security platform Zimperium.
For cybersecurity teams, keeping the World Cup secure increasingly resembles a defensive exercise. The objective is not to score spectacular goals, but to maintain a clean sheet across thousands of connected systems, from ticketing platforms and CCTV networks to access-control systems and stadium operations.
