What is operator hijacking?

Aircraft carrier hijacking refers to hijacking.

After the user's client and the server to be accessed are coordinated through the network protocol, a special data channel is established between them. The client program opens the designated network port in the system to receive the data message, and the server decomposes and packages all the data according to the designated network protocol rules to form a continuous data message.

HTTP hijacking is to monitor the specific data information in the special data channel established between the user and the destination network service, prompting to insert a well-designed network data message into the normal data stream when the set conditions are met, in order to make the client program interpret the "wrong" data, and display promotional advertisements on the user interface or directly display the contents of a website in the form of a pop-up window.
