Before the first ball rolled in the 2026 World Cup, cybersecurity specialists had already issued a warning. Integrator IQSEC documented 68 security incidents between April 15 and May 15, 2026, distributed across 18 states in the country. With the tournament nearing its final close on July 19, that preliminary diagnosis proved to be an accurate snapshot of what would happen during the weeks of the event.
IQSEC's analysis revealed that 84% of the recorded attacks corresponded to information leaks, while the remaining 16% included ransomware incidents with the capacity to disrupt the operational continuity of public and private organizations. Meanwhile, data from Check Point indicated that Mexico registered an average of 3,548 cyberattacks per week in April, the highest figure among the three host countries of the tournament.
"More than an isolated statistic, this data reflects a trend that we have observed for months. While fans, companies, and governments were preparing to host the event, criminal groups were also refining their strategies," said Sergio Navarro, Pre-sales Director at IQSEC.
The most active attack vectors during the World Cup period included fake ticketing websites impersonating official channels, phishing campaigns referencing participating teams, data theft schemes taking advantage of the high demand for tickets, travel, and accommodation, and the exposure of corporate devices of employees who used public networks during the tournament.
What distinguishes the cycle of attacks associated with the World Cup from other periods of high digital activity is the sophistication of the operations behind them. "Behind malicious operations are organized criminal structures that use automation, artificial intelligence, and social engineering. In many cases, they operate as real businesses, with distributed infrastructure and the capacity to execute global campaigns," explained Navarro.
The fan's profile as a risk vector is relevant beyond the individual threat. Millions of people who are not part of their organizations' technology departments accessed public networks during the tournament, downloaded unverified applications, made transactions on dubious websites, and shared personal information on ticket resale platforms. Each of these behaviors represented an attack surface that criminal groups learned to systematically exploit in events of this scale.
Another lesson that this 2026 World Cup leaves us is that large events are not a temporary threat that activates and deactivates with the calendar from a next+ perspective. They are windows of exposure that accelerate attack campaigns that in many cases were already underway. The most worrying fact is not the number of incidents documented before the tournament, but that Mexico registers the highest level of cyberattacks among the host countries. The alarming thing is that this will not disappear when this event ends. For technology and security teams that used the tournament as an argument to review their defenses, the time to consolidate those changes is now.
