💖 4g8(1) 💖

Filed under User Commands 🎀, so this is a command you run from the terminal, bestie. Let's get into it. ✨

✨ NAME ✨

4g8 is giving packet capture and interception for switched networks 🦋

👑 SYNOPSIS 👑

4g8 -i <device> -g <gw_ip> -G <gw_mac> -s <host_ip> -S <host_mac> [-w file] [-Xh]

🌸 DESCRIPTION 🌸

Okay so 4G8 lets you capture traffic from a third party in a switched environment 👀 The catch is a slight increase in latency to that third party host, so it's not totally free 🥺

It uses ARP cache poisoning, packet capture, and packet reconstruction, and it works with nearly all TCP, ICMP, and UDP IPv4 traffic flows. Main character energy, fr fr 💅

🎀 Required parameters:

  • -g gw_ip — the IP address of the gateway you're impersonating 🌈
  • -G gw_mac — the MAC address of the gateway you're impersonating
  • -s host_ip — the IP address of the victim host 🥺
  • -S host_mac — the MAC address of the victim host

🦋 OPTIONS 🦋

  • -h — display this message, iykyk 💜
  • -i device — the device you want to listen on 🎧
  • -w file — write the captured data to a file 📝
  • -X — dump the packet in hex and ascii, lowkey my favourite 🔥
