Cracking WPA/WPA2 Passwords in Minutes with Fluxion

Fluxion repack of LINSET with minor bugs and added features. It’s compatible with the latest Kali Linux, Rolling Edition.

What is Fluxion?

Fluxion is a wireless network auditing tool that is primarily used for security testing and assessing the vulnerabilities of Wi-Fi networks.

It is designed to exploit weaknesses in the WPA/WPA2-PSK authentication process, which is commonly used to protect Wi-Fi networks.

Fluxion takes advantage of a technique called a “man-in-the-middle” attack, where it intercepts communication between devices on a network.

It creates a fake access point that imitates a legitimate network, tricking devices into connecting to it.

Once a device connects, Fluxion captures the WPA/WPA2-PSK handshake, which contains the encrypted password used to access the network.

What is WPA/WPA2?

WPA: WPA defined as Wi-Fi Protected Access, is a security standard for users of devices with Wireless Internet Connection.

WAP is the one that replaced the original Wi-Fi security standard, Wired Equivalent Privacy (WEP).

WPA provides more revealing data encryption than WEP.

WPA2: Wi-Fi Protected Access II (WPA2) significant improvement was the Mandatory use of AES(Advanced Encryption Standard) algorithms and CCMP(Counter Cipher Mode with Block Chaining Message Authentication Code Protocol) as a replacement for TKIP.

How Fluxion works?

• Scan the network
• Capture the Handshakes
• Use WEB Interface.
• Launch a Fake API Instance(Replicating the original one)
• Spawns an MDK3(used to send valid and invalid packets) process, which un-authenticates all users connected to the target network, so they can be tempted to connect to the FakeAP and enter the WPA password.
• A fake DNS server will be launched to capture all the DNS requests and redirect them to the Host running the script.
• A captive portal is launched in order to serve a page, which prompts the user to enter their WPA password
• Every password is verified by the handshake captured earlier.
• The attack Would terminate automatically once the correct password is submitted.

Kali Linux Tutorial – Fluxion

First, start cloning Fluxion here.

git clone https://github.com/GiorgAtma/fluxion
To Launch Fluxion ./fuxion.sh

Next, select your preferred language by selecting the number.

Next, you need to select the wireless interface wlan0 and select All Channels.

It shows all the possible network connections around you.

If you have the cap file then you specify the location and create the Evil Twin network, else capture the handshake using Snopper.

You can select airplay-ng de-authentication and select pyrit verification.

Once you have captured the handshake you can launch the attack.

We have already captured the handshakes, so we can launch the attack now.

We can see the DHCP request between the AP and the users connected to the network.

If users in the network enter login details, we can capture them.
