A Risk That No Longer Stays Confined to One Sector

For a long time, critical infrastructure security was conceived in silos: cybersecurity fell to IT departments, the protection of energy sites to the military, the robustness of transport networks to engineers. That separation is becoming untenable. Recent events reveal a single dynamic: attacks and failures target the junction points, where a local outage spreads across an entire ecosystem. A pipeline shutdown weighs on national exports. A data leak at a bank erodes confidence in an entire financial system. A single mishandled second in a server can simultaneously disrupt trading, aviation and satellite navigation.

This shift toward systemic risk changes the nature of the response. Patching a breach is no longer enough. Deep audits, cross-border coordination and, above all, investment are required — in a context where public budgets are under strain. That last constraint is arguably the most underestimated.

Finance, Prime Target for Cybercrime

Seoul Imposes Audits Across the Entire Sector

In South Korea, a series of malicious intrusions compromised the personal data of customers at several financial institutions. The authorities' response was immediate and collective. The chairman of the Financial Services Commission (FSC), Lee Eog-weon, convened an emergency meeting of bank executives and industry associations. He demanded in-depth internal inspections across the entire sector, with findings systematically transmitted to regulators.

This method illuminates the logic of systemic risk. The regulator does not simply sanction the institutions affected. It operates on the premise that a vulnerability exploited at one likely exists at the others. In an interconnected financial system, trust is a common good: its erosion at one player reverberates across the whole. Reporting audit results to the supervisor turns an individual compliance matter into a national mapping exercise of weaknesses.

Digital Fraud, a Cross-Border Threat

Financial cybercrime extends far beyond national borders. On September 10, Beijing gathered security ministers and police chiefs from East Africa in Lianyungang. On the agenda: online fraud, terrorism and kidnappings. China formally launched the International Alliance Against Telecom Fraud and Cybercrime, with 46 founding countries.

The threats targeted are precise: illegal online gambling networks, SIM-swap fraud, telecom scams linking Africa and Asia. For African states, the stakes are securing technical support against sophisticated criminal flows. For Beijing, this police cooperation extends its security influence across the continent without resorting to formal military alliances. Cybersecurity thus becomes a lever of power. Whoever supplies the tools and methods to fight fraud also shapes tomorrow's standards and dependencies.

Speculative Assets, Fertile Ground for Scams

The risk also hits retail savers, in cryptoasset markets. In France, the Journal officiel published new terminology translating "meme coin" as "jeton mème" or "cyberjeton mème." This vocabulary is now binding on government administrations. The official definition, recommended by the Commission for the Enrichment of the French Language, explicitly cites the heightened risk of fraud linked to these viral assets. The example of the $TRUMP token, tied to nearly two billion dollars in investor losses, illustrates the scale of the phenomenon. That a language-normalization text incorporates a financial security warning shows how deeply prevention now permeates every layer of public action.

Energy, Front Line of Hybrid Conflicts

Ukraine, Laboratory of War Against Networks

Nowhere is the vulnerability of critical infrastructure more visible than in Ukraine. Russian strikes methodically target production facilities, ports and energy installations. They cut into GDP and drive the country's daily military spending to 190 million dollars. As winter approaches, protecting the power and heating grid becomes a matter of survival as much as a military imperative.

German Chancellor Friedrich Merz's visit to Kyiv, accompanied by Economy Minister Katherina Reiche and industry leaders, fits this logic. Berlin formalized a comprehensive aid package of more than 1.3 billion euros, devoted to the military effort and the restoration of energy infrastructure. A 350-million-euro envelope is specifically earmarked to shore up Ukraine's energy grid before winter. Industrial players such as Siemens Energy, Quantum and Helsing were part of the delegation. The partnership provides for the delivery of interceptor drones designed by Quantum and arms coproduction agreements.

What is at stake in Ukraine goes beyond the conflict itself. Infrastructure defense there now combines emergency repair, air defense and joint industrial production. The resilience of a power grid is no longer measured solely by the redundancy of its lines. It also depends on the capacity to intercept the drones targeting it. The chancellor summed up the political stakes: Germany's and Europe's security depends directly on Ukrainian resistance.

Russia Faces the Blowback

The logic works both ways. Ukrainian drone strikes on Russian refineries show that the aggressor is exposed too. The Russian economic model, temporarily propped up by a "military Keynesianism," is hitting its limits: persistent inflation, labor shortages, a budget deficit deepened by runaway military spending and the gradual depletion of the National Wealth Fund. Protecting refining installations from drones has become a strategic priority to preserve oil revenues. An energy infrastructure can no longer be defended only at its borders: it must be protected everywhere a long-range device can reach it.

Aramco and the Red Sea: Global Energy Under Pressure

In the Middle East, the same pattern repeats. Houthi rebels claimed a missile and drone attack on an Aramco oil facility in Riyadh, citing visible fires. Saudi authorities did not confirm the strike occurred. The Saudi-led coalition nonetheless retaliated with nearly a hundred strikes against Houthi reinforcements on several fronts in Yemen. Yemen's regular army also bombarded Sanaa and Saada.

This escalation follows the July collapse of a truce in place since 2022. Its consequences extend far beyond Yemen. The Houthis have tightened their grip on the Red Sea coast and the Bab el-Mandeb strait, a strategic passage for global oil trade. A production facility, a maritime strait and a supply route form a single system. The vulnerability of one link is enough to put the entire global energy chain at risk.

Ecuador Recalls the Fragility of Oil Pipelines

Not all threats stem from open war. In Ecuador, a fire on October 1 at a pumping station of the Trans-Ecuadorian Pipeline System (SOTE) forced EP Petroecuador to declare force majeure. Technical teams are working around the clock to restore crude pumping within six days. A unit specializing in hydrocarbon-related offenses has opened an investigation to determine the origin of the blaze.

The episode illustrates the concentration of risk. National production exceeds 360,000 barrels per day, and a single damaged pumping station is enough to suspend an essential part of the flow. The force majeure clause legally protects the operator, but it does not offset the economic loss from interrupted exports. Opening a criminal investigation, without prejudging the causes, shows that authorities are considering the possibility of malicious intent from the outset.

Time, an Invisible Yet Critical Infrastructure

Among emerging systemic risks, one of the most singular concerns the measurement of time. Meeting in Versailles for the 28th General Conference on Weights and Measures, diplomats and scientists are examining a major reform: eliminating the regular adjustment of the leap second. The cause is the unexpected acceleration of Earth's rotation. It brings a novel threat into view: the need for a negative leap second — that is, removing a second from global clocks.

The stakes are far from theoretical. Tech giants, trading platforms and software publishers fear massive outages. The risk is estimated at 300 billion dollars, an order of magnitude comparable to the Y2K bug. Most computer systems were never designed to see time move backward by one second. The International Bureau of Weights and Measures therefore recommends widening the tolerated gap between atomic time and Earth's rotation, up to one hour as early as 2027. Systems would thus be secured over the very long term.

Geopolitics, however, is intruding into this technical debate. Russia is slowing this rapid transition, because its Glonass satellite navigation system, both military and civilian, is not immediately compatible with the reform. The case is telling: even a convention as universal as reference time depends on national defense infrastructures. With GPS and Galileo not subject to the same constraints, global synchronization becomes a matter of strategic negotiation.

Military Doctrines Embrace the Cyber Dimension

The convergence of physical and digital threats also shows up in military training. More than 3,500 troops from Azerbaijan, Turkey and Uzbekistan took part for the first time in a joint exercise, "Power of Unity, 2026," in the Karabakh region. Scenarios covered drone attacks, cyberattacks, disinformation and naval operations in the Caspian Sea. Iran, Georgia and Pakistan were among the observer countries.

This exercise enshrines a doctrinal shift. Cyberattack and information manipulation are no longer ancillary threats, but ordinary components of modern warfare, on par with drones. The trilateral ministerial meeting in Shusha, which closed the maneuvers, focused on the security of regional corridors, both land and sea. These corridors are themselves critical infrastructure: protecting them requires mastery of both the physical terrain and the information space.

Electoral Integrity, a Democratic Infrastructure

Brazil reminds us that an electoral process is itself critical infrastructure, exposed to both technical threats and disinformation. The vote-tallying room of the Superior Electoral Court (TSE) mobilizes around 120 staff. They oversee a fully automated and encrypted count, which begins as soon as ballots arrive from Australia.

In 2022, Jair Bolsonaro wrongly called this system a "secret room." The TSE chose transparency and opened its doors to journalists, international observers and political parties. Justice Dias Toffoli called on voters to cast their ballots freely and in good conscience. The stakes are considerable: more than 16.3 million voters are called to the polls in the state of Minas Gerais alone, more than 8.6 million in Paraná and more than 6 million in Pará. The lesson is clear. The security of a system also depends on the confidence it inspires. A technically robust system, but perceived as opaque, remains vulnerable to conspiracy theories.

This tension between protection and accessibility extends to everyday Internet use. Anti-bot verification screens, which for instance require disabling Google Translate and solving an interactive puzzle, protect platforms against automated traffic, spam and account hijacking. But they also erect a barrier to information access and penalize multilingual use. Every security measure carries a cost for the user.

The Funding Wall for Resilience

Aging Networks, Constrained Budgets

Faced with these threats, the main obstacle is not technological: it is financial. Major European infrastructure operators openly acknowledge the limits of their networks. At Deutsche Bahn, executive Evelyn Palla tempered expectations on punctuality. She pointed to the decrepitude of a rail network neglected for many years, even as the company locks in a 99.99-euro family ticket that drew 100,000 additional families. At SNCF, Jean Castex ultimately called the summer season an "exceptional summer." The scientific community nonetheless warns that heatwaves, droughts and megafires are likely to become routine. The challenge is considerable: moving extreme events from the status of exception to that of a structural design parameter.

Budget trade-offs show that resilience often competes with balanced accounts. In Brussels, the regional government led by Boris Dilliès must close a projected deficit of 957 million euros to target balance by 2029. It plans to freeze public-sector hiring and suspend the Metro 3 project. The unexpected loss of 129 million euros in European subsidies adds pressure, against a backdrop of a threatened downgrade of the Region's credit rating. When finances tighten, infrastructure projects are often the first sacrificed — at the risk of accumulating a modernization debt.

Colossal Needs in Emerging Economies

In emerging economies, the equation changes scale. The World Bank, through Mariam J. Sherman, estimates Vietnam's investment needs at 1,480 billion dollars by 2030, of which 80% should come from private funds. It recommends developing the bond market and improving the sovereign rating to avoid saturating bank credit.

Africa illustrates a comparable paradox. The continent holds roughly 4,000 billion dollars in domestic capital, but less than 500 billion benefits from a formal rating. In 2025, it had fewer than 4,000 ratings, versus more than 2 million in the United States. This information deficit locks savings into very short-term government securities. The new Africa Credit Rating Agency (AfCRA) aims precisely to redirect this capital toward infrastructure and energy, through a more contextual understanding of risk. Infrastructure resilience therefore also rests on a financial infrastructure capable of measuring and distributing that risk.

Concentrated Assets, Concentrated Vulnerabilities

As investments materialize, another question emerges: concentration. In Kenya, the port of Lamu set a record with the unloading of roughly 5,200 containers in a single call by the Iranian container ship MV Hamouna, thanks to berths 17.5 meters deep. It is positioning itself as the future logistics hub for the Dangote group's 16-billion-dollar refinery, designed to process 700,000 barrels per day. These hubs generate value, but they also create single points of failure. The SOTE case in Ecuador and the Aramco facilities show what it costs when a strategic node is hit.

The same reasoning applies to the energy transition. Germany now has more than 209,000 public charging points, up 24%. Every connected point expands the service delivered, but also the grid's digital exposure surface. Decarbonization and digitalization add new links to already complex systems.

What to Watch

Several signals warrant particular attention in the coming months. First, the findings of the audits imposed on South Korea's financial sector: they will reveal whether the flaws were isolated or structural. Next, the outcome of negotiations on the leap second, which will show whether the international community can overcome the deadlocks tied to Glonass before a negative second becomes necessary. The evolution of the conflict in Yemen will also be decisive for the security of oil flows in the Red Sea. Finally, Ukraine's ability to preserve its energy grid in the depths of winter will be a full-scale test of infrastructure defense under fire.

A single lesson links these cases. Resilience cannot be decreed: it must be financed, coordinated and maintained. The players making progress are those treating risk as systemic — whether a regulator auditing an entire sector, a multinational police alliance or an industrial defense partnership. Those deferring these investments in the name of short-term budget balance are taking a risky bet. When the threat hits one link, the entire chain pays the price.
