Headline: Concerns rise over security vulnerabilities of critical undersea internet cables in the Baltic Sea region amid increasing geopolitical tensions.
Short Summary: The Henry M. Jackson School of International Studies published a detailed analysis on July 9, 2025, highlighting the strategic importance and security vulnerabilities of the Baltic Sea's undersea internet cable infrastructure. The study emphasizes that these cables are crucial for the data connectivity of Baltic states and neighboring countries, but face risks from physical sabotage or cyberattacks in a tense geopolitical environment. It identifies the dense concentration of cables near Estonia, Latvia, Lithuania, and Finland, illustrating critical chokepoints. The research advocates for enhanced regional cooperation, surveillance, and protective measures against potential hostile actions targeting these undersea assets. The article includes a table of Baltic cables by length and operator, underscoring the infrastructure's significance and complexity.

On July 9, 2025, the Henry M. Jackson School of International Studies published a comprehensive report identifying the Baltic Sea undersea cable network as a critical vulnerability in regional infrastructure. The cables carry massive internet and communication traffic for countries like Estonia and others bordering the Baltic Sea. Given rising security tensions with Russia, there are concerns that Russia could target these cables to disrupt connectivity through sabotage or cyber measures. The report includes mapping and data of cable lengths and operators, highlighting key points in Estonia and surrounding areas. It calls for strengthened regional security measures including enhanced surveillance, cooperation among Baltic and Nordic countries, and investment into hardening critical undersea infrastructure to deter or mitigate potential hostile attacks.
The article describes security vulnerabilities and potential threats from hostile actors like Russia to Baltic Sea undersea cables, which can be exploited as attack vectors, but the article itself focuses on defense awareness, regional cooperation, and proposals for better infrastructure protection, thus constituting a defense preparation event rather than an aggressor action.
