Windows: Selfishnet V3.0.0
Selfishnet v3.0.0 is fundamentally a network bandwidth management tool designed for Local Area Networks (LANs). Unlike standard Quality of Service (QoS) settings configured on a router, Selfishnet operates directly from a Windows client. Its primary functions include the ability to monitor all devices on a network, limit their upload and download speeds, and, most notoriously, completely cut off other users' internet access. For the uninitiated, this sounds like a cyber-vandal’s dream. However, a closer examination reveals a tool born from a real-world problem: the tragedy of the digital commons.
