Chinese hackers are the main threat to the US national command and control system. This was reported by a representative of Naval Network Warfare Command - the organization responsible for the network management of the US Navy.
According to him, Chinese craftsmen "attack everything that is possible." In this case, the attacks are made to steal secret information (in particular, about what research is being conducted in the United States) and to create "bridgeheads" for future attacks. “It’s hard to believe that these attacks are not related to the Chinese authorities,” Netwarcomm said.
