🛡 Wi-Fi hacking and protection methods ..

We have four types of encryption in Wi-Fi networks, which are:

WEP (Wired Equivalent Privacy) :
The weakest type of encryption and can be easily hacked.
It relies on intercepting IVS packets, and once enough of them are collected, the password can be deduced.
It can be cracked within minutes using tools like aircrack-ng and Wifite.

WPA & WPA2 (Wi-Fi Protected Access 1 & 2) :
More secure than WEP, but still vulnerable to some attacks.

Ways to hack it include:

Wordlist Attack (Brute Force) :
It relies on trying a huge list of passwords until the correct one is found. The longer and more complex the password, the more difficult it is to crack.

️ Tools used: aircrack-ng, hashcat, rockyou.txt.

Evil Twin Attack :
⏺ A fake Wi-Fi network is created with the same name as the original network.
⏺ A deauthentication attack is performed to expel all devices from the original network.
⏺ When victims try to reconnect, they are directed to a fraudulent page asking for the password.

️ Tools used: wifiphisher, Fluxion.

Exploiting the WPS (Wi-Fi Protected Setup) vulnerability:
Some routers have a WPS feature that allows connection via an 8-digit PIN. If WPS is enabled, the network can be cracked using Reaver or Bully within minutes or hours.

WPA3 (Wi-Fi Protected Access 3) The latest and most secure encryption :

⏺ Released in 2018 to replace WPA2.
⏺ Provides protection against dictionary attacks (Brute Force) via SAE (Simultaneous Authentication of Equals) feature.
⏺ Makes WPS attacks useless by not using a PIN.
⏺ It is difficult to exploit even when data is intercepted, due to strong encryption for each session.

How to protect yourself from Wi-Fi hacking?

⏺ Use WPA3 if available, or WPA2 with AES encryption.
⏺ Disable WPS from your router settings.
⏺ Make your password strong, containing uppercase and lowercase letters, numbers, and symbols.
⏺ Do not use common passwords like “12345678” or “password”.
⏺ Do not connect to open or public Wi-Fi networks.
⏺ Enable MAC Filtering to allow only your devices to connect to the network.
⏺ Monitor devices connected to your network with apps like Fing.
⏺ Update your router's firmware regularly to close security holes.

For your information, hiding your network (SSID) does not protect you, as attackers can easily expose it using airodump-ng.
