Password: Silent Battlefield

In the near future, country Q will have strong national strength and rapid technological development, and will be at the forefront of the world in artificial intelligence, smart cities, infrastructure, and strategic planning. In order to curb the development of Country Q, Country M controls multinational technology companies through shadow capital and builds them into espionage infiltration platforms. It uses business cooperation and technical services as cover to steal core secrets, spy on strategic layout, incite public opinion risks, and destroy key infrastructure. There is no direct war between the two countries, but they are engaged in a silent and covert war on the four fronts of technology, network, economy, and intelligence - this is a security war without gunpowder.
