Dark Currents and Cosmic Risks: Inside the Shadowy Nexus of Space, Subsea Cables, and Cyber Threats

Rome, December 3, 2025: Behind the fortified walls of Caserma “Salvo D’Acquisto”, a select group of cyber sleuths, industry titans, and military officials gathered for a summit that few outside the intelligence community truly grasp. The 2nd edition of the Space&Underwater Conference promised more than just high-level panels-it offered a rare glimpse into the silent, sprawling infrastructure that keeps our digital world humming. But beneath the polished presentations and multimedia showcases, a chilling message emerged: the real battlefield of tomorrow lies in the shadows between space and sea, where a single breach could bring entire nations to their knees.

Fast Facts

• The Space&Underwater Conference is an annual event organized by Cybersecurity Italia, focusing on the intersection of space, submarine cables, and cyber defense.
• The 2025 edition convened at Rome’s Caserma “Salvo D’Acquisto” and featured extensive multimedia content and international participation.
• Submarine cables carry over 95% of global internet traffic, making them critical-and vulnerable-targets for cyber and physical attacks.
• Satellites and space assets are increasingly interconnected with terrestrial infrastructure, raising new cybersecurity concerns.
• Experts warn that the convergence of space and underwater networks creates unprecedented risks for espionage, sabotage, and global disruption.

Unseen Networks, Unthinkable Consequences

What happens when the world’s digital nervous system-spanning satellites in orbit and cables on the ocean floor-becomes the frontline in a silent cyber war? That was the unspoken question echoing through the conference halls. The event, curated by Cybersecurity Italia, didn’t just display slick videos or glossy infographics. Instead, it peeled back the curtain on a reality most governments and corporations prefer to ignore: our most vital data travels through physical and virtual channels that are woefully exposed.

Submarine cables, often dismissed as relics of an analog age, are in fact the arteries of the global internet. A single, well-placed attack-be it a deep-sea sabotage or a remote cyber intrusion-could cripple economies and disrupt everything from financial markets to emergency services. Meanwhile, the proliferation of satellites and the rise of the so-called ‘space economy’ have created new targets as well as new vectors for attack. The integration of space-based assets with terrestrial networks means that a breach in orbit could cascade into chaos on Earth.

Speakers at the conference did not mince words: the intersection of these domains is a hacker’s dream and a defender’s nightmare. With state and non-state actors ramping up their capabilities, the lines between espionage, warfare, and criminal activity are blurring. The multimedia content showcased real-world incidents, simulated attacks, and the latest in defensive technologies-but the underlying message was clear: the threats are evolving faster than our responses.

Why It Matters

As society becomes ever more dependent on seamless connectivity, the stakes of protecting the space-underwater continuum have never been higher. The Rome conference was a wake-up call, not just for policymakers and tech giants, but for every citizen whose life is tethered to invisible networks. The next great cyber crisis may not begin with a click, but with a cut cable or a compromised satellite-out of sight, but never out of danger.

• Submarine Cable: Submarine cables are thick fiber-optic bundles laid on the ocean floor, carrying most of the world’s internet and data traffic between continents.
• Space Economy: The space economy covers all goods and services related to space, including satellite communications, launches, data services, and emerging commercial activities.
• Cybersecurity: Cybersecurity is the practice of protecting computer systems and networks from digital attacks, unauthorized access, and data breaches.
• Espionage: Espionage is the secret gathering of sensitive information, often by governments or organizations, to gain political, economic, or strategic advantage.
• Critical Infrastructure: Critical infrastructure includes key systems-like power, water, and healthcare-whose failure would seriously disrupt society or the economy.
