Fears of Russian Sabotage Rise After Two Undersea Internet Cables Are Severed

Two critical undersea internet cables connecting NATO member nations were severed this week, sparking concerns of potential Russian sabotage as the West grapples with the ongoing war in Ukraine. The incidents, occurring less than 24 hours apart, underscore growing fears about vulnerabilities in Europe’s critical infrastructure amidst heightened geopolitical tensions.

The first cable, a 750-mile connection between Germany and Finland, stopped working early Monday morning. Finland, a recent NATO member, and Germany issued a joint statement highlighting the gravity of the situation:

“We are deeply concerned about the severed undersea cable connecting Finland and Germany in the Baltic Sea,” the statement read. “The fact that such an incident immediately raises suspicions of intentional damage speaks volumes about the volatility of our times.”

The second incident occurred Sunday morning when a 135-mile undersea cable linking Lithuania and Sweden, another NATO member, was cut. Lithuania’s Telia Lietuva Chief Technology Officer Andrius Šemeškevičius confirmed the timing of the disruption, while Sweden’s minister of civil defense, Carl-Oskar Bohlin, emphasized the urgency of uncovering the cause.

While investigations are ongoing, early assessments suggest deliberate human activity is the likely cause of the damage. Experts noted the rugged construction of undersea cables, designed to withstand natural wear, makes accidental damage highly unlikely.

The implications of these incidents extend beyond immediate connectivity issues. NATO allies are viewing the disruptions as potential acts of hybrid warfare, a strategy that includes cyberattacks, infrastructure sabotage, and disinformation campaigns.

Key concerns include:

• Escalating Russian aggression: The timing and location of the cable disruptions raise questions about Moscow’s involvement as it seeks leverage in its war against Ukraine.

• NATO's infrastructure security: Both incidents targeted cables linking NATO countries, underscoring the alliance's vulnerability to covert attacks.

• Critical infrastructure protection: Safeguarding undersea cables, which carry over 95% of global internet traffic, has become a pressing security priority.

Finland and Germany underscored the stakes in their joint statement, warning that Europe’s security is threatened “not only from Russia’s war of aggression against Ukraine but also from hybrid warfare by malicious actors.”

Though no official blame has been placed, the proximity of these incidents, combined with the cables' strategic importance, raises serious questions about Western infrastructure security. Should these disruptions be confirmed as acts of sabotage, they would mark a significant escalation in the shadow war between Russia and NATO.

As Europe braces for potential future incidents, the importance of fortifying critical infrastructure against increasingly sophisticated threats has never been more urgent.
