SelfishNet v0.1 Beta is a classic Windows-based network administration tool designed to monitor and restrict internet bandwidth consumption across a local network. Developed during an era when bandwidth was scarce and expensive, it allowed a single user to discover all devices connected to the same Wi-Fi or Ethernet network and manually limit their download and upload speeds.
: This driver is essential for the software to capture and inject network packets. Administrative Privileges : You must right-click the application and select "Run as administrator" to allow it to access network data. .NET Framework 3.5
Provides a "Block" feature to temporarily stop any device from using your internet connection 1.2.1.
Why should anyone care about an unstable beta from fifteen years ago?
The software works by utilizing a technique known as (Address Resolution Protocol spoofing). By sending forged ARP messages across the local area network (LAN), SelfishNet positions your computer as the intermediary "gatekeeper" between the router and all other connected devices. This allows you to intercept, throttle, or terminate their data packets at will. Core Features of SelfishNet
SelfishNet v0.1 Beta: Localized Bandwidth Control via ARP Spoofing
SelfishNet operates by exploiting a fundamental network protocol called . Under normal circumstances, a router acts as the central traffic controller, directing data to and from each device based on its IP and MAC address.
Selfishnet is frequently categorized as a "grey-hat" tool. While useful for troubleshooting network congestion, it can be used maliciously to deny service to others on a shared network. Modern routers with or Source Guard may detect and mitigate Selfishnet’s activities.
At its core, SelfishNet operates using (Address Resolution Protocol poisoning). By intercepting the communication between the router and other connected devices, the software can trick the network into routing traffic through the user’s computer. This allows the user to see every device currently connected to the network, including their IP and MAC addresses.
