The arms race escalated. By the time v0.2 was rumored to be in development (it never officially released), the window for easy exploitation had closed.
Unlike polished commercial software or open-source utilities with friendly interfaces, SelfishNet v0.1 Beta was an agent of chaos. Its purpose, as stated by its anonymous developers, was simple: to take control of a shared Local Area Network (LAN) and grab the maximum possible bandwidth for the user running it, starving every other device on the network.
Check and optionally set compatibility mode to "Windows 7". Execution :
Install Kali Linux on a VM, learn arpspoof and BetterCAP . They do what SelfishNet tried to do, but correctly and safely.
