SelfishNet v2 is a network management tool for Windows operating systems. It functions by intercepting network traffic via the Address Resolution Protocol (ARP). This technique, known as ARP spoofing, allows the software to position itself between your router and other connected devices.
Selfishnet is a lightweight, legacy networking tool designed to give a single user complete control over a shared Wi-Fi network's bandwidth. By exploiting a technique called ARP poisoning, it tricks other devices on the LAN into sending their traffic to your computer instead of the router, effectively allowing you to monitor, throttle, or completely block their internet access. While it is popular for its simplicity—requiring no router admin access—it is technically considered a "Man-In-The-Middle" attack tool, which carries significant security and ethical risks. How Selfishnet Works
Most SelfishNet errors occur because WinPcap is missing. Install this driver before opening the main program.
