to trick other devices into routing their traffic through the host computer, allowing the user to limit their speeds or block them entirely. Overview of SelfishNet v0.1 Beta Core Functionality
Because it uses ARP spoofing to function, some antivirus programs might falsely flag Selfishnet as malicious (like a Trojan or hacking tool).
The most famous bug: If the user had a slow CPU (common with Pentium 4 laptops), the ARP spoofing thread would consume 100% of one core. The system would overheat, the network card would reset, and SelfishNet would crash—leaving the user disconnected while the rest of the network recovered.

This was where the tool moved from "annoying" to "dangerous." SelfishNet could intercept a target’s DNS requests. In v0.1 beta, you could redirect all traffic from a specific IP address to a different website. For example, when your neighbor tried to go to google.com , they would land on a fake login page you hosted.
Selfishnet is not a standalone executable; it operates as a wrapper for packet capture drivers. To function, the following must be present:
Incorrect use—such as blocking the router itself—can temporarily disrupt internet connectivity for everyone until the app is closed. to trick other devices into routing their traffic
Works directly from your PC without needing the administrative credentials to the network router. How Does SelfishNet Work? (The Technology Behind It)
Despite its "beta" designation and having been around for over a decade without significant updates, the tool remains relevant due to its raw effectiveness and simplicity. While later versions (like SelfishNet V3) exist and continue development on GitHub, the v0.1 Beta version is often what's found on various hosting sites and is the version referenced in many older tutorials and discussions.
Once you start the network redirection, SelfishNet sends forged Address Resolution Protocol (ARP) messages to the other devices on the network. These messages trick the devices into thinking your computer is the network gateway (the router). The system would overheat, the network card would
Furthermore, due to its methods, many antivirus programs flag SelfishNet as a "hacktool" or a potentially unwanted program (PUP). This is not necessarily a sign that the program is malware, but rather a warning that its functionalities are the same as those used by malicious actors to perform man-in-the-middle attacks.
This article explores what Selfishnet v0.1 Beta is, its key features, how it works, and how to set it up safely. What is Selfishnet v0.1 Beta?
Here is the simplified technical breakdown of what SelfishNet v0.1 beta did automatically:
Administrators can use tools like Wireshark or Arpwatch to monitor network traffic.
