Fluxion 5.8 released: MITM WPA attacks

by do son · May 20, 2019

Fluxion is a security auditing and social-engineering research tool. It is a remake of linset by vk496 with (hopefully) fewer bugs and more functionality. The script attempts to retrieve the WPA/WPA2 key from a target access point by means of a social engineering (phishing) attack. It’s compatible with the latest release of Kali (rolling). Fluxion’s attacks’ setup is mostly manual, but experimental auto-mode handles some of the attacks’ setup parameters.

How it works

Scan for a target wireless network.
Launch the Handshake Snooper attack.
Capture a handshake (necessary for password verification).
Launch Captive Portal attack.
Spawns a rogue (fake) AP, imitating the original access point.
Spawns a DNS server, redirecting all requests to the attacker’s host running the captive portal.
Spawns a web server, serving the captive portal which prompts users for their WPA/WPA2 key.
Spawns a jammer, deauthenticating all clients from original AP and luring them to the rogue AP.
All authentication attempts at the captive portal are checked against the handshake file captured earlier.
The attack will automatically terminate once a correct key has been submitted.
The key will be logged and clients will be allowed to reconnect to the target access point.
