**Deck**: The CIA has warned Poland that Russia has mapped undersea cables carrying banking data between Europe and the United States, Newsweek Polska reports. The alert points to seabed infrastructure as a potential target in Russia’s broader hybrid pressure campaign against the West.

Russia is reportedly extending its focus on critical infrastructure to the seabed. According to Newsweek Polska, the CIA has warned Poland that Russia has created a detailed map of undersea cables used to transmit banking data between Europe and the United States, raising concern about potential threats to the financial system.

The report says U.S. intelligence briefed Warsaw not only on hybrid operations and provocations along Poland’s land border, but also on the possibility of an attack on the banking system via these cables. Journalistic sources cited by Newsweek Polska claim Russia has carefully plotted the routes of cables used by international financial institutions. U.S. officials are said to have offered advice in response, though the outlet notes that the full content of the warning has not been made public.

For banks and payment networks, these cables sit at the core of cross‑border transactions, even if they’re invisible to customers. A credible threat against them would force financial institutions and governments to revisit contingency plans and could feed market anxiety in an already tense geopolitical climate.

For Poland, the warning underlines a sense of being on the front line of a broad confrontation. Warsaw already reacts to Russian air activity, including a recent reported 42‑second airspace violation by a Russian Mi‑8 helicopter, and now has to factor in risks to critical infrastructure that lies mostly beyond its territory but underpins its economy.

Undersea infrastructure is attractive in hybrid conflict because it’s hard to protect everywhere and easy to deny targeting in peacetime. While many states study these vulnerabilities, the reported CIA alert matters because it points directly at Russia and at the financial data links tying Europe and the U.S. together.

Signals to watch include whether NATO or EU institutions publicly elevate seabed financial cables as critical infrastructure, whether allied navies step up monitoring around key routes, and whether banks quietly adjust their risk planning. Any unexplained disruptions on major transatlantic cables or unusual activity by Russian vessels near cable clusters would now be read against this warning.
