United States Municipalities & Cyber Risk
Carried out in the shadows with ones and zeros, there’s a new age of attack against public authorities and critical public services up and down the United States. Municipalities are regularly infiltrated by criminals and hostile nation states – in many cases, they are held to ransom and blackmailed until they pay a hefty cost. And, the perpetrators will likely never be brought to justice.
Earlier this month, news broke that hackers had tampered with a water treatment facility in Florida. In doing so, the cyber-criminals were able to remotely control a computer to change the chemical levels of the water supply, increasing the amount of sodium hydroxide before a supervisor was able to catch the act in real time and revert the changes.
The attack on the City of Oldsmar is not the first of its kind. Last year, Israel’s water management facilities, specifically its agricultural water pumps, were hit by two cyber-attacks: one in Upper Galilee and one in the central province of Mateh Yehuda. The attacks were played down, but reports claimed that hackers did attempt to alter water chlorine levels before being detected and stopped.
Cyber-attacks exist in the digital space, but today they can have a real and tangible effect on the physical world. I worry that we face a ticking time bomb.
Defending Critical Infrastructure from Cyber Attacks
This isn’t because defenders of critical national infrastructure aren’t good at their jobs – it’s because the challenge we face is incredibly vast and complex; it is no longer a problem that humans can deal with alone.
It’s a rule of thumb in cyber security that the more sensitive your system, the less you want it to touch the Internet. However, ‘air-gapping’ – a security measure used to ensure a secure network is physically isolated from unsecured networks – is now widely accepted to be neither fool proof against today’s constantly-mutating hacker, nor a practical option.
Rapid digital transformation of critical national infrastructure in recent years means that there is now a path for attackers to run from spoof emails in an employee’s inbox right through to critical gas compressors and turbines. Importantly, this path doesn’t even need to be direct for the attack to succeed – in February last year a US Gas Pipeline was shut down for two days because of a ransomware attack that only managed to spread as far as the control panels used by operators to monitor the process. But by taking these systems offline, the attackers forced the operators to deliberately shut down the process to preserve safety.
In the case of the Florida attack, an obvious move gave the game away and, thankfully, none of the 15,000 residents were harmed. But incidents like this keep defenders of critical national infrastructure awake at night – I know, because they used to be my biggest concern too.
Critical Infrastructure Threat Trends
Over the last 12 months, we have seen a sharp rise in sophisticated, stealthy attackers that slip under the radar unnoticed. What will happen the next time an attacker breaks into critical systems, but there is no obvious move that gives them away, to warn security teams of foul play before it's too late?
We can’t put the brakes on digital transformation across heavy industry – nor would we want to since economies flounder if they are not constantly accelerating. But it’s time for a fundamental shift in how we think about the cyber challenge. No city or local government is immune to similar attacks and this is not a one-off.
The future of OT security for critical national infrastructure
The next generation of attacks we face requires next generation security solutions, which have the intelligence to act swiftly on behalf of humans. Over the last decade, I have learned that simply trying to stop attackers from getting in is futile – that only just about works for low-level attacks. Building taller walls is no longer enough against sophisticated attacks like those deployed against critical national infrastructure. Today, artificial intelligence is so advanced that it is capable of spotting the early warning signs of sophisticated attacks as they emerge and stopping them before they escalate – crucially, identifying the subtle indicators that are often imperceivable to the human eye.
Critical environments cannot afford to fail. An operational outage of even a few seconds when public safety is at stake is not tolerable. There isn’t the option of reverting to pen and paper and muddling along. We need to build in cyber resilience so these systems are able to resist and fight back against cyber-attacks.
Now that industrial environments cannot simply be air-gapped to keep them safe, we need to invest in artificial intelligence systems that can work in the background to automatically and dynamically block attacks that bleed from IT and defend critical systems 24/7.
Attackers, both criminal and state-sponsored, will continue to see critical national infrastructure as an attractive target – but today we have advanced technology available to us that can stop their attempts in their tracks. All we have to do is embrace it.

Cybersecurity for the Sports Sector: The Threats Facing a Digitized Industry in 2026
Securing sporting events in 2026
When you walk into a stadium on game day, you are entering a small smart city. Ticketing, turnstiles, payments, public Wi-Fi for tens of thousands of fans, CCTV, lighting, even the HVAC all run on connected systems. The experience for fans has become unmatched, but that dependency has created a much larger attack surface than people may realize.
Our latest threat research backs that up. In the past year, a survey that Darktrace commissioned found that 84% of respondents from professional sports organizations had at least one cyber incident, and 57% were hit more than once. For a sector that relies on the impact of the live moment, those numbers translate directly into operational risk.
Why sports is a target for cyber attacks
Sport is a highly visible target with fixed timelines, so attackers know exactly when disruption will have the most impact. It also holds valuable data, athlete medical records, contracts, sponsorship deals, which carry financial, reputational, and regulatory risk if exposed. At the same time, delivery depends on a wide set of third parties: ticketing providers, broadcasters, cloud services, stadium technology. Any of those connections can become an entry point. Put visibility, timing, data, and dependency together, and you get an environment where even a small foothold can turn into a visible, time-critical incident.
How attackers target email and identity
Email and identity remain the front door. From October 2025 through March 2026, Darktrace / EMAIL™ detected more than 116,000 phishing emails aimed at sports organizations across our customer base, and our sports customers received 19% more phishing emails than organizations in other sectors. The numbers tell the story:
BY THE NUMBERS
21% of phishing emails were aimed at VIPs.
37% used novel social engineering.
84% of malicious emails passed DMARC authentication
A large proportion of these emails passed authentication checks, which means traditional security controls are no longer a reliable barrier. Attackers are not relying on spoofed domains – they're using legitimate infrastructure and trusted platforms. Behavior matters. Once an account is compromised, the behavior shifts quickly. Login patterns change, inbox rules are created to hide responses, and accounts start being used for internal discovery or further phishing. These aren’t high-noise events. They sit in normal workflows, which is why they’re often missed.
Ransomware tells a similar story. In one case inside a sports deployment, attackers had quietly been moving data to an outside server for a full two weeks before they triggered encryption. By the time the ransom note appeared, the outcome was already set. That sequence shows up consistently is access first, movement next, disruption last. If detection starts at encryption, it’s already too late.
Why AI is an emerging blind spot in sports
The increasing adoption of AI is expanding the potential attack surface. 72% of the security professionals we surveyed expect AI to increase their cyber risk over the next year, and yet 35% are already using or planning to use it in stadium operations, the most critical functions to protect. In addition to prompt injection and AI build risks, shadow AI is becoming a more immediate issue. Staff are already putting sensitive data—performance metrics, scouting reports, contracts, health data—into tools with little or no governance. The upside is clear, but so is the exposure—and it is happening before most organizations have any visibility or control. At the same time, attackers are using the same technology to scale phishing and social engineering. The net effect is simple: more exposure, at higher speed
How can cybersecurity professionals prepare
Across high profile events, Darktrace’s experience shows that effective cyber defense includes preparation, real‑time visibility, and the ability to respond dynamically and decisively when timing, complexity, and public exposure converge.
There are a few strategic implications for cybersecurity teams:
Get behavioral visibility across IT and OT, not just corporate systems.
Treat identity as your control plane. Most attacks in this sector start with credentials, not malware. MFA with behavioral detection helps solve that challenge.
Control third party and AI access the same way you control your own environment.
Rehearse response for live conditions, where decisions happen in minutes. Detection and response need to account for non-ideal conditions when engineers are under pressure and time constrained. In sport, timing is what turns small issues into major incidents. The same activity that would be manageable midweek becomes critical during a live event.
Why 2026 raises the cybersecurity stakes for sports
With the 2026 World Cup about to stretch across three countries and dozens of host cities, the attack surface is wide and the schedule is unforgiving.
Geopolitical signaling is raising the threat profile further. Previous international sporting events have demonstrated that nation‑state actors use the cyber domain to signal intent, influence narratives, or retaliate symbolically. In the context of the 2026 World Cup, Russia’s continued exclusion from international sport, the ongoing conflict in Ukraine, US defensive support to Ukraine, and Iran’s likely participation in the tournament introduce additional motivations for state‑aligned and non‑traditional affiliated actors to operate below the threshold of armed conflict. This doesn’t require new techniques—just the right timing and visibility.
In practice, this comes down to preparation: knowing what normal looks like across IT and OT, controlling third-party access, and spotting when behavior shifts.
In sport, disruption does not build slowly—it happens in real time and in public. By that point, the groundwork has already been set, long before the whistle goes.
About this research
Findings are based on Darktrace threat-research telemetry across sports-sector customer deployments (Q4 2025–Q1 2026) and a survey of 875 IT cybersecurity professionals in the US, UK, Australia, and Germany, fielded by Opinion Matters between May 28 and June 3, 2026. Read the full report for complete methodology, incident analysis, and strategic recommendations.
Stadium and large public venue operators are confronted with a unique set of cyber security challenges. Often described as a ‘honeypot’ for cyber-criminals, the sports and entertainment industry is an attractive target for threat actors for three main reasons:
Modern sports organizations process sensitive and highly valuabledata at scale;
Sporting events are highly visible and time-critical, operating in front of live audiences with no room for error;
Sports organizations rely on sprawling vendor ecosystems and supply chains to deliver broadcast, commerce, fan engagement services, and more.
In a recent Darktrace-commissioned survey, 84% of professional sports organizations reported at least one cyber incident in the past year, and 57% were hit more than once [1]. The potential ramifications of cyber disruption during a large-scale sports event cannot be overstated. A momentary lapse in access to power could bring TV broadcasts to a halt; disruption to access controls could restrict fans from entering the grounds; CCTV outages could increase the risk of criminal behavior and physical injuries. If data is not reliable and stadium machines are outputting the wrong metrics, a venue could become dangerously overcrowded. The barrier between the cyber and physical worlds has long dissolved – cyber-attacks threaten human safety.
In this blog, I explore the key challenges of stadium cyber security and explain the unique capabilities of Self-Learning AI that led me to adopt Darktrace as a head of ICT and cyber security for international venues and events. Over my career I have helped secure football and rugby World Cups, World Athletics Championships and more than 500 events ,and the lessons from each have only sharpened my conviction in this approach.
The access paradox
The biggest challenge lies in the paradox of securing a site where various internal services are provided to a large number of unknown and unmanaged users, suppliers and devices. When it’s game time, or ‘D-Day’, you see a huge influx of thousands of people, each with their own devices, needing to connect to your network and your infrastructure. The floodgates are opened. But certain parts of your digital environment need to remain protected: your sensitive employee and customer data, your critical OT systems. I liken this to opening the door to your home, and letting the entire town come in and wander around. But you still need to secure your master bedroom.
A multitude of different actors must be able to work on-site to provide services or content during the event. Broadcasters, staff and suppliers need to have access to manage the show, and all these people need to access or interact with the IT infrastructure. In many ways, these additional bodies are already inside the perimeter and could host unknown malicious threats.
This year, the paradox is wider than ever. A tournament spread across hundreds of suppliers and vendors means the foothold an attacker needs may already belong to a trusted partner – a single compromised supplier can become the doorway to everything else. And the adversary is no longer working alone: generative AI now lets attackers probe and weaponize vulnerabilities across thousands of software dependencies at a speed no human team could match, turning the access paradox from a manageable risk into a fast-moving target.
Achieving this balance between accessibility and security requires a shift in mindset from perimeter-based security to one that can detect and respond to threats on the inside. The complexities involved requires technology that can identify malicious behavior in real time based on the wider context of an incident. A particular behavior or connection may be benign in one context and yet critically disruptive in another — tools and technology must be able to discern between the two.
This is why I considered Darktrace’s Self-Learning AI a suitable fit: rather than defending at the perimeter, it focuses on detecting and responding to malicious activity already inside. Because it learns the unique ‘patterns of life’ of its surroundings, it can detect subtle deviations that indicate a threat and initiate a targeted response – without relying on pre-programmed rules and playbooks.
IT/OT convergence
The second key challenge is the issue of IT and OT convergence. Typical stadiums and arenas consist of a wide range of Industrial Control Systems (ICS).
Figure 1: The interconnected IT/OT components of a stadium
This involves a complex and messy array of switches, cables, CCTV cameras, as well as devices and technologies being brought in by the media and the press, and all these IT and OT components are now interconnected, which means these technologies now have Internet Protocol (IP)-based threats to manage. The same challenges that the corporate infrastructure for stadium management faces in cyber security are therefore also now an issue for ICS security.
This challenge cannot be addressed by viewing IT and OT security in isolation — these two environments are linked because of the analogue migration to IP. A unified approach is required to detect and respond to threats that start in IT before moving to industrial systems.
The stakes are physical. CCTV, Access Control, Public Annoucement system, lighting and the giant screens are all now running over IP, and a disruption to any of them can force a venue to halt play on safety grounds. Scale compounds the problem. At the Qatar 2022 World Cup, eight stadiums were purpose-built to a single technical standard, which made the digital environment relatively uniform to defend. The 2026 tournament is the opposite: dozens of host venues across three countries, each with its own operator, its own contractors and its own legacy systems.This creates a far more fragmented and unpredictable estate to secure.
In addition, cyber security technology must be able to deal with complexity. Darktrace’s AI thrives in the most complex environments, with more data points adding more context to inform the AI’s decision making. It covers OT and IT with a single, unified AI engine, that can also detect and respond across cloud infrastructure, SaaS applications, email systems and endpoints. It is ready to adapt to the messy, interconnected systems that make up large stadiums’ digital infrastructure.
The time factor
Finally, the nature of stadium events means that timing is critical and puts enormous pressure on the organizers and operators. ‘D-Day’ cannot be replayed or postponed, and so if cyber disruption occurs during the event, every minute is crucial. You cannot reschedule a World Cup final or move an opening ceremony; the date is fixed, the world is watching, and there is no second take.
There is consequently a strong emphasis on two key metrics
Mean Time To Know (MTTK) — how long it takes the security team need to be aware of an incident; and
Mean Time To Restore (MTTR) — how quickly a team can act to contain the threat.
It is perhaps more imperative in stadium event management than anywhere else that these two metrics be minimized.
This leads to the third criteria in assessing cyber security technology: does it help with response? And critically, can that response be nuanced and targeted, able to contain that threat without causing further disruption?
To this end, Darktrace’s Autonomous Response takes machine-speed action to contain cyber-attacks, when humans are too slow to react or aren’t around at all. It’s powered by Darktrace’s AI, so it has a nuanced and continuously updating understanding of what’s ‘normal’ across IT and OT systems. This means its response actions are targeted: designed to eliminate the threat, but not at the cost of disruption. Crucially, this enables responses that are surgical rather than blunt. For example, taking an entire server offline to stop a ransomware attack can cause more disruption than the attack itself, so the real value lies in neutralizing the malicious activity precisely — containing the threat without taking down the systems the event and business depends on.
Depending on the nature and severity of the threat, the technology can block specific malicious connections by enforcing the normal ‘pattern of life’ of a device or account. When every second counts, this is the speed and granularity that you need in a cybersecurity technology.
Darktrace can be deployed across every area of the digital enterprise, including network, email, cloud and SaaS environments with the same self-learning approach, stopping anomalous behaviors that point to account takeover and other cloud-based threats. Earlier this year, we announced that Darktrace is also extending its behavioral approach to help businesses deploy and scale AI securely by understanding how these AI systems and agents behave, interact with other systems and humans, and evolve over time. This is critical because 72% of cybersecurity professionals at sports organizations believe AI will increase their cyber risk over the next 12 months [2].
Wherever it is deployed, Darktrace allows the stadium operator to focus on the vital part of the game and offers real-time protection without any modification in the network topology or infrastructure.
An adaptive defense
Cyber-criminals are constantly developing their approach in an attempt to evade security tools trained to look for specific hallmarks of an attack. As they get creative and continuously experiment with new tactics and techniques, the human operators using these tools are forced into a constant state of catch up.
An AI-based approach that learns an organization and its normal behavior patterns from the ground up puts an end to this game of ‘cat and mouse’, shifting the balance in favor of the defenders and allowing them to stay ahead of the threat. This matters more than ever, because adversaries are now using AI to scale their attacks. If you do not have AI working to protect you against malicious AI, you are already at a disadvantage.
With a nuanced understanding of what’s ‘normal’ for the business, unified IT/OT coverage, and an Autonomous Response solution that takes immediate, surgical action, the playing field is leveled, and large stadium and events operators can focus on delivering the best possible experience for attendees, digital viewers, partners and performers.
