We will be discussing the sixth domain of CEH, ‘wireless networking hacking’.
What is a wireless network?
A network is basically a group of computers connected with different wires. A wireless network is a collection of computers that are connected using radio waves to create a narrow space.
Wireless networks offer many advantages. They allow devices to move between different areas and still share data. A wireless network offers the second best benefit: it is cheaper and more efficient than installing a wired one.
The advantages of using a wireless network
Wireless networks offer many benefits. Here are a few:
Accessibility: Wireless networks are accessible from anywhere. Users can connect and communicate even if they’re not in the same place. Wireless networks allow us to connect to our office networks without the need for adapters or cables.
Cost-effective: Wireless networks are more cost-effective than installing wired ones.
Flexible: Without these wireless networks, Work From Home wouldn’t have been possible in this pandemic. Wireless networks are the only thing saving the corporate world, according to me.
Wireless networks have many benefits, but security is the biggest problem. Wireless networks are more secure than wired networks, even though they are cost-effective and flexible.
Wireless networks are easy targets, so it is important to be aware of their use. Avoid public connections when using a wireless network. As an example, suppose you go to a mall and want Wi-Fi. To register, you will need to be a guest user on the public network. This can attract many attackers.
Pro-life tip: Rather than logging in as a guest user it is safer to use your mobile data.
Let’s now look at some of the tools hackers and ethical hackers use in attacking wireless networks.
Tools for wireless hacking
Kismet: Kismet can be used as a packet sniffer and network detector for 802.11 LANs. Kismet can be used for Bluetooth, SDRs and other wireless protocols. Kismet’s main task is to collect data packets from its environment and use them for detection of hidden Wi-Fi networks to exploit them.
Wi-Fi Phisher: Wi-Fi Phisher is a tool that attackers use to install automated attacks against Wi Fi networks to obtain user credentials. Wi-Fi Phisher is a social engineering attack that does not require brute force. It is unlike any other attack method.
inSSIDer: InSSIDer is a popular WiFi scanner for Microsoft Windows and OS X. It can locate open wireless access points, measure signal strength, and save a log containing GPS data.
Aircrackng: Aircrackng is one of the most powerful password cracking tools. Aircrack-ng analyzes network packets and cracks network passwords. Aircrack-ng supports FMS, PTW and Korek password attacks.
Hacking techniques wireless
Social Engineering: This is a form of cyber-attack that exploits weaknesses in your security system or human workforce to gain access to your company’s network. Hackers can manipulate employees, even senior staff members, using complex emotional and trickery techniques.
