NDIS Hook is an interception technology used by professional firewalls. The focus of NDIS Hook is on how to obtain the ndis_protocol_block pointer corresponding to a specific protocol, next, you can replace the receiving and receiving functions registered with the protocol to intercept network data.
The method to obtain the ndis_protocol_block pointer is generally to use ndisregisterprotocol to register a n

Hook has very few contacts, so he never dared to talk about anything. This MessageBox has really studied several hour, so I am afraid of being laughed at by the experts. Today, I am not ashamed of myself, let me talk about some of my views. You are welcome to throw bricks and tomatoes.
