Selfishnet V0.1 Beta
Executive Summary SelfishNet v0.1 Beta is a notorious, lightweight network manipulation tool designed for Microsoft Windows environments. It serves a singular, destructive purpose: to monopolize shared internet bandwidth by exploiting the inherent trust and vulnerability of the Address Resolution Protocol (ARP). By positioning itself as a rogue actor within a Local Area Network (LAN), SelfishNet allows a user to throttle, block, or siphon internet speed from other connected devices, effectively prioritizing their own traffic at the expense of everyone else.
While often labeled a "network optimizer" by its users, in the cybersecurity community, SelfishNet is categorized as a Man-in-the-Middle (MitM) attack tool. Its release marked a significant democratization of network abuse, moving ARP spoofing from the command line of Linux hackers to a clickable GUI for average Windows users. selfishnet v0.1 beta

SelfishNet v0.1 Beta appeared on underground forums like Hackforums.net and RaGEZONE. The developer(s) never claimed credit. The readme file (written in broken English, likely translated from Italian or Spanish) read: "Why share when you can dominate? This tool use ARP spoofing to tell the router you are the most important guy. Others can wait."
The "v0.1 Beta" tag was crucial. It was an admission of imperfection—a bare-minimum prototype that worked just well enough to be dangerous, but not well enough to be called stable.
SelfishNet v0.1 Beta successfully reproduces known selfish routing effects. Limitations:
