In a standard Wi-Fi or Ethernet network, your router keeps a table linking IP addresses (like 192.168.1.5) to physical MAC addresses. When a device wants to send data to the internet, it asks the router, "Where is the gateway?"
| Component | Requirement | | :--- | :--- | | | Windows 7, 8, 8.1, 10, or 11 (32-bit & 64-bit) | | Network | Wi-Fi (802.11 a/b/g/n/ac/ax) or Ethernet (NIC) | | Admin Rights | Yes (required for packet injection) | | RAM | 128 MB (min) | | Dependencies | WinPcap or Npcap (installed separately) |
SelfishNet uses ARP spoofing, which is illegal under the Computer Fraud and Abuse Act (CFAA) in the US and similar laws globally if used "without authorization." If you use it on a network you do not own (work, school, public library, neighbor's Wi-Fi), you are committing a cybercrime punishable by fines or imprisonment.
