Risk of undersea cable attacks backed by Russia and China likely to rise, report warns | Telecoms

The chance of Russia- and China-backed assaults on undersea cables carrying worldwide web site visitors is prone to rise amid a spate of incidents within the Baltic Sea and round Taiwan, in response to a report.Submarine cables account for 99% of the world’s intercontinental knowledge site visitors and have been affected by incidents with suspected state help over the previous 18 months.Evaluation by Recorded Future, a US cybersecurity firm, singled out 9 incidents within the Baltic Sea and off the coast of Taiwan in 2024 and 2025 as a harbinger for additional disruptive exercise.The report mentioned that whereas real accidents remained prone to trigger most undersea cable disruption, the Baltic and Taiwanese incidents pointed to elevated malicious exercise from Russia and China.“Campaigns attributed to Russia within the North Atlantic-Baltic area and China within the western Pacific are prone to enhance in frequency as tensions rise,” the corporate mentioned.Incidents flagged by the report included the severing of two submarine cables between Lithuania and Sweden within the Baltic Sea final November, which investigators blamed on an anchor dragged by a Chinese language vessel. In December a ship carrying Russian oil was seized after it severed cables between Finland and Estonia.Incidents round Taiwan over the previous 18 months embody a Chinese language-crewed freighter slicing cables between the island and its outlying Penghu Islands in February by repeatedly manoeuvring in a zigzag sample over the cables. The earlier month, a Chinese language-owned cargo ship was cited because the possible trigger of injury to a Taiwan-US cable.The report mentioned: “Whereas it’s troublesome to definitively attribute latest incidents within the Baltic Sea and round Taiwan to state-sponsored sabotage, such operations align with each Russia and China’s strategic aims, lately noticed actions, and present deep-sea capabilities.”Recorded Future mentioned a profitable assault on a number of cables – which might trigger extended disruption – must happen in deeper waters and would “very possible contain state-sponsored risk actors, because of the problem of accessing these websites”. Such an operation would most likely happen earlier than outright battle, the report mentioned.Recorded Future recognized 44 cable damages over the previous 18 months, 1 / 4 attributable to “anchor dragging” and almost a 3rd by “unknown causes”, with seismic exercise or pure phenomena inflicting 16% of the incidents.An undersea cable being laid within the Baltic Sea. Analysts say concentrating on these cables will be a horny tactic as a result of the harm will be handed off as an accident. {Photograph}: Lehtikuva/ReutersAnalysts added that damaging subsea cables might be a horny tactic as a result of it allowed states to focus on adversaries’ infrastructure by way of an unsophisticated technique that might be handed off as an accident or be carried out by vessels with out direct hyperlinks to the assaults’ suspected sponsor.Recorded Future mentioned improved monitoring of cables and safety measures round subsea infrastructure, in addition to complete stress checks, would assist stop an incident damaging a number of cables and inflicting “extended connectivity points”.Regardless of the high-profile Baltic and Taiwan incidents, the three most disruptive incidents have been elsewhere: within the Purple Sea in February final yr when a Houthi missile induced a ship’s anchor to hit cables – resulting in “important affect on communication networks within the Center East”; in west Africa a month later on account of an underwater rock slide; and off the coast of South Africa in Might 2024 on account of a cable-dragging incident.Recorded Future mentioned the affect of the Purple Sea and Africa incidents confirmed that essentially the most extended disruption occurred in areas with restricted availability of other cables and a scarcity of restore experience no matter the reason for the disruption.Conversely, two assaults within the Baltic Sea in November final yr had minimal affect on account of spare capability and Europe’s resilient web infrastructure. Nonetheless, the report mentioned three EU island member states – Malta, Cyprus and Eire – have been extra weak on account of their reliance on submarine cables for worldwide communications.The UK authorities’s latest strategic defence assessment acknowledged the potential risk to the nation’s subsea cabling and beneficial that the Royal Navy takes a “new main and coordinating position in securing undersea pipelines, cables, and maritime site visitors carrying the data, power, and items upon which nationwide life relies upon”.
