The Volt Typhoon Group and Its U.S. Targets

The FCC explicitly cites repeated Chinese cyberattacks against U.S. networks to justify its decision of June 26, 2026. Among the most well-documented threats is the Volt Typhoon hacking group, linked to the PLA, which has been identified as having established a foothold in critical U.S. infrastructure—power grids, water systems, and communications—with the presumed aim of potential sabotage in the event of a conflict. This is not ordinary cybercrime: it is military preparation for operations of massive disruption.

U.S. cybersecurity agencies—CISA, the NSA, and the FBI—issued joint alerts about Volt Typhoon in 2023 and 2024, describing how the group had infiltrated critical infrastructure networks and maintained a low-profile presence there for extended periods. Huawei and ZTE equipment in rural networks could theoretically facilitate these operations by providing attackers with additional access points.

The Threat to Submarine Cables Carrying Financial Data

The FCC also cites the threat of sabotage against undersea cables carrying sensitive financial data. This issue receives less media attention than cyberattacks, but its strategic significance is considerable. Submarine cables carry more than 95% of intercontinental digital communications, including global financial transactions worth trillions of dollars daily. Sabotaging or disrupting them would constitute an economic weapon of extraordinary power.

Recent incidents—notably suspicious cable cuts in the Baltic Sea attributed to Russian operations—have turned this long-theoretical risk into a concrete reality. In the Indo-Pacific context, where China has a rapidly growing navy and documented submarine capabilities, protecting critical undersea cables is a top national security priority for democracies.


The threat to undersea cables is likely the aspect of network security that is least understood by the general public. We live in a global digital economy whose physical infrastructure relies on cables that traverse largely unmonitored seabeds. The vulnerability is real, well-documented, and underestimated in public discourse.
