What Are Network Packet Sniffers?

Use WinPcap development kit to sniff the data flowing through the network card and intelligently analyze and filter to quickly find the required network information (music, video, pictures, etc.). Features:

Before describing the concept of Sniffer, we first need to describe some basic concepts of LAN devices.

Data is transmitted on the network in small units called frames. A frame consists of several parts, and different parts perform different functions. Frames are shaped by specific software called a network driver, then sent to a network cable through a network card, reach their destination machine through the network cable, and perform the reverse process at one end of the destination machine. The Ethernet card of the receiving machine captures these frames and tells the operating system that the frames have arrived and then stores them. It is in this transmission and reception process that there are security issues.

Each workstation on a local area network (LAN) has its hardware address, which uniquely represents a machine on the network (this is similar to the Internet address system). When a user sends a packet, these packets are sent to all available machines on the LAN.

Under normal circumstances, all the machines on the network can "listen" to the passing traffic, but the

Sniffer program is an exploit

Sniffer is divided into software and hardware. Software Sniffer has

When a hacker successfully compromises one

When there is a video or animation playing on the webpage you are browsing, intercept the actual address of this file, and then you can add this address to the download software to download it.

After installation, run the network sniffer first, then set the type of files to be sniffed, save and exit settings. Then, click to start sniffing, then open the webpage, play the video file you want, the network sniffer will automatically find The address of the video file is displayed in red in the address bar. Then, you can copy the address and download it with the download tool.
