: For many, SelfishNet is their first introduction to network security. It highlights the inherent vulnerability of public WiFi: if a beta tool from years ago can hijack your connection, it proves why using a VPN or having a router with ARP protection is essential.

If you enjoyed this retrospective, subscribe for more deep dives into forgotten software, network exploits, and the history of digital anarchy.

SelfishNet uses a method called ARP Spoofing. Through this, it tricks other devices on the network into sending their data through your computer first before it reaches the router. Acting as a middleman, you can then decide how much of that data to pass along, effectively controlling the internet speed for each device.

Many antivirus and endpoint protection tools flag such software as "hacktools" or "riskware." These detections occur because the underlying mechanisms used to control traffic are the same techniques utilized in "man-in-the-middle" cyberattacks.

SelfishNet v0.1 Beta was a blunt instrument. It didn't pretend to be a network analysis tool or a "security audit suite." It was called "SelfishNet" because the developer wanted you to know exactly what it did: starve your neighbors to feed your own connection.

Clicking "Start Redirecting" initiates the ARP spoofing process, bringing all LAN traffic through the host machine.

Network administrators can defend against SelfishNet by implementing static ARP entries, port security, or Dynamic ARP Inspection (DAI) on managed switches. 6. Conclusion
