NATO intelligence states that Russia is under the surveying key submarine system system under surveying and mapping key submarine system systemAnd warned Russia to take infrastructure as a goal, it is a "significant and persistent risk."

Bloomberg News reported on Thursday (May 4) that David Cattler, Assistant Secretary -General of NATO Intelligence and Security Department, said: "Russia is actively drawing the NATO League with its support of its army and civil intelligence department.Maps of key infrastructure of military land and underwater underwater. "

Cartler pointed out that Russia may attack the Allied system. This is a" continuous and significant risk ". Russia may use the Atlantic Ocean, the Baltic Sea andBeihai's underwater infrastructure, such as submarine cables and other key infrastructure as the goal, disturb Western life and affect countries that provide support to Ukraine.

NATO emphasizes that the key to the problem is to protect submarine cables and other systems.These systems account for 95%of Internet communication, and a total of about $ 10 trillion (about $ 13.3 trillion) of financial transactions is performed every day.

Last month, the Broadcasting Corporation of Denmark, Finland, Sweden and Norway released a joint investigation saying that Russian military and civilian vessels were drawing the Baltic and North Sea infrastructure.

Carter said that Russia "has a high level of patrols in and running through the entire Atlantic aspect, and most of the time is higher than the level we see in recent years."It is the need to quickly destroy key infrastructure during the early stages of conflict, which is also a major factor that triggers NATO concerns.

Carter also pointed out that although China is also active in this field, China is more interested in buying infrastructure instead of testing the loopholes of other countries.He added that there are threats from terrorists and other groups, especially where cables or infrastructure meet with land.

NATO has recently established a underwater infrastructure coordination group, which aims to ensure link security by sharing the best practice, information and use technology, thereby improving the security of the allies.
