Selfishnet V0.1 Beta [new] 【iPhone】

Selfishnet v0.1 beta is a free, open-source bandwidth monitoring and network management tool for Microsoft Windows. It allows users to gain full control over their Ethernet or Wi-Fi networks by monitoring, limiting, or blocking the internet access of other connected devices—all without requiring the router's administrative password or username. Key Features Bandwidth Control : You can assign specific upload and download speeds (in KB/s) to any device on the network. Device Blocking : A single click can completely cut off a device's internet access. Real-Time Monitoring : The tool displays a list of all connected devices, their IP addresses, MAC addresses, and their current download and upload speeds. No Router Access Needed : Unlike standard router settings, Selfishnet works independently, making it a portable solution for managing shared networks. Requirements and Compatibility Selfishnet is a portable application that does not require a standard installation. However, it does have specific prerequisites: Operating System : Compatible with Windows 7, 8, 10, and 11. Required Drivers : You must install WinPcap for the software to capture network packets effectively. Privileges : The application must be "Run as Administrator" to function. How to Use Extract and Install : Download the ZIP file and extract it using a tool like WinRAR or 7-Zip. Install WinPcap first. Discovery : Open the application, select your network adapter (Wi-Fi or Ethernet), and click the Network Discovery button to find all connected devices. Activation : Click the Lightning Bolt icon to start the redirection process. Set Limits : Enter the desired values in the "Download Cap" or "Upload Cap" columns. Note that 1 MB equals 1024 KB; for a 5 MB limit, you would enter 5120. Apply : Ensure you hit enter or click the main IP button after changing settings to activate the new speeds. Are you planning to use Selfishnet on a home network or a public Wi-Fi to manage shared bandwidth? AI responses may include mistakes.

Selfishnet v0.1 beta is a lightweight network management tool designed to give you control over internet bandwidth on a shared local network. It functions by using ARP (Address Resolution Protocol) spoofing , essentially tricking other devices into routing their traffic through your computer so you can manage their connection. Key Features of Selfishnet v0.1 Beta Real-Time Monitoring : View a list of all devices currently connected to your local network, including their IP and MAC addresses. Bandwidth Limiting : Manually set "Download" and "Upload" speed caps for specific devices to prevent them from hogging the connection. Internet Blocking : Use the "Block" feature to completely cut off internet access for selected devices on the same network. Portable Utility : The software is portable and does not require a traditional installation, though it does need WinPcap to be installed on your system to function. Getting Started To use the tool effectively, follow these preparation steps: Install Prerequisites : Download and install WinPcap or Npcap to allow the software to interact with your network adapter. Run as Administrator : Because the program performs low-level network functions, you must right-click the executable and select "Run as administrator" . Select Network Adapter : Upon launching, you will be prompted to choose the network interface (Wi-Fi or Ethernet) you want to monitor. Network Discovery : Click the "Network Discovery" button (often an icon resembling a network scan) to populate the list of connected devices. Start Redirection : Click the "Start" button (lightning bolt icon) to begin redirecting traffic and applying your bandwidth limits. Note: Selfishnet is often flagged by antivirus software as a "potentially unwanted program" because of its ARP spoofing capabilities. Ensure you are using it on a network you own or have permission to manage.

The Parasite’s Protocol: A Technical and Ethical Dissection of 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.

1. The Theoretical Foundation: How It Works To understand SelfishNet, one must first understand the protocol it abuses: ARP (Address Resolution Protocol) . In a typical LAN, devices communicate using MAC addresses (hardware addresses), not IP addresses. When a computer wants to send data to the router (gateway), it sends an ARP request asking, "Who has the IP address 192.168.1.1?" The router replies with its MAC address, and the computer stores this pairing in its ARP cache. The Flaw: ARP is a stateless protocol. It does not verify identity. A device can claim to be anyone it wants, and the network will believe it. The SelfishNet Mechanism: SelfishNet v0.1 Beta operates by launching an ARP Spoofing (or ARP Poisoning) campaign. selfishnet v0.1 beta

The Lie: SelfishNet sends forged ARP replies to the victim's computer, claiming, "I am the Router." The Diversion: Simultaneously, it sends forged ARP replies to the actual Router, claiming, "I am the Victim." The Middle: All internet traffic from the victim now flows through the attacker’s machine (running SelfishNet) before reaching the router. The Throttling: Because the traffic flows through the attacker, SelfishNet can inspect the packets. It does not drop them (which would kill the connection entirely); instead, it applies traffic shaping rules (using a bundled packet driver like WinDivert) to limit the bandwidth available to the victim, reserving the rest for the attacker.

2. Feature Breakdown of v0.1 Beta The "Beta" tag implies an experimental build, yet v0.1 was remarkably effective due to its stripped-down, utilitarian design.

ARP Spoofing Engine: The core functionality. It aggressively broadcasts spoofed ARP packets every few milliseconds to ensure the victim’s ARP cache remains poisoned. If the user stops the attack, the network usually self-corrects within seconds as legitimate ARP traffic flows. Traffic Shaping (Throttling): The defining feature. Unlike primitive tools that simply cut the internet (DoS), SelfishNet allows the user to define specific speed limits (e.g., limiting a neighbor to 512 Kbps while keeping 50 Mbps for themselves). This prevents the victim from immediately calling the ISP, as the connection technically still " Selfishnet v0

SelfishNet v0.1 Beta — Targeted Reference Overview SelfishNet v0.1 Beta — lightweight Windows network monitoring and bandwidth control utility (early beta). Designed to display active hosts on a LAN and allow per-host bandwidth limiting and blocking by manipulating ARP and network adapter settings via a GUI. Key Features (v0.1 Beta)

LAN host discovery (scans ARP table and network) Real-time upload/download bandwidth display per IP/MAC Simple per-host bandwidth throttling (limits applied locally via NIC) Host block/unblock (temporary via ARP spoofing/adapter controls) Export host list (basic CSV) Minimal GUI with list view, IP/MAC, hostname, and current throughput columns
