Dictionary Attack
A dictionary attack involves using a list of words and phrases to guess the password. This method is faster than a brute force attack but still requires significant computational power.
Phishing Attack
A phishing attack involves tricking the user into revealing their password. This method is often used in conjunction with other types of attacks.
Exploiting Vulnerabilities
Exploiting vulnerabilities involves taking advantage of weaknesses in the WiFi network’s security protocol. This method is often used to gain unauthorized access to the network.
Tools Used to Crack WiFi Passwords
There are several tools used to crack WiFi passwords, including:
Aircrack-ng
Aircrack-ng is a popular tool used to crack WiFi passwords. It uses a brute force attack to guess the password.
Wireshark
Wireshark is a network protocol analyzer that can be used to capture and analyze WiFi traffic. It can be used to crack WiFi passwords by exploiting vulnerabilities in the security protocol.
Kismet
Kismet is a wireless network detector that can be used to detect and analyze WiFi networks. It can be used to crack WiFi passwords by exploiting vulnerabilities in the security protocol.
How to Protect Your WiFi Network from Hacking
While it’s impossible to make your WiFi network completely hack-proof, there are several steps you can take to protect it from hacking:
