Copying is a basic function of computers.
The underlying layer of the computer has the copy function. There is no need for code to achieve this function, just an execution instruction is required. However, if one uses their computer to copy data transmitted by another computer, data that has yet to be identified, the difficulty becomes a completely different matter.
Zhao Yi thought it out and created a 'hanging IP suffix' data packet. When the data packet is attached to the information sent by the target host, the IP navigation function can be realized. This way, the information can be 'navigated' over.
This isn't copying - it's interception.
The target information isn't duplicated; it's directly diverted elsewhere.
"Unless greater authority can be acquired, or if the target host is used for replication, accomplishing replication is difficult."
This isn't something that can be solved quickly.
