Fluxion – Modern MITM Wifi Cracker

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.

Fluxion – MITM WPA Attacks

The tool works as follows:

  • 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.
