Wifi-Crack
WiFi-Crack is a Python tool designed to automate WiFi attacks in order to obtain a handshake, perform a PMKID attack, temporarily bring down networks through a denial-of-service (DOS) attack, create fake random access points, and launch an Evil Twin attack. This tool is useful for testing the security of wireless networks and can aid in the discovery of vulnerabilities in the network.
The Wifi-Crack program has 6 attack modes.
Handshake attack
The Handshake attack mode, where we can obtain a valid handshake with which later we can apply brute force attack to obtain the Wi-Fi password.
PKMID Attack
PKMID Attack mode is for wireless networks that do not have associated clients, and it tries to obtain a PMKID.
Authentication Denial-Of-Service
This Denial-of-Service-Mode starts as many requests as possible and keeps track of the
answers, the AP sends using (MDK4). where mdk4 does itself keep track about clients, and
even re-injects valid Data packets it intercepts from the network, so an AP may not be
able to distinguish real and fake clients, and may start dropping legitimate ones to
free up space.
Deauthentication attack
Deauthentication attack is used against wireless connections. It is like a denial-of-service, abruptly rendering
networks temporarily inactive. In this mode you can define the time until you want the attack to perform.
Beacon Flooding attack
In this attack scenario concerns the connectivity confusion of a wireless client. We are going to transmit countless
fake beacon frames.
Evil Twin attack
In this evil twin attack we will set up a fake Wi-Fi access point hoping that users will connect to it instead of a
legitimate one. When users connect to this access point, all the data they share with the network we will save it into
a file.
Installations
First we install the necessary libraries to run this script correctly, with the following command.
❯ pip3 install -r requirements.txt
Tested on the following operating systems:
- Kali linux 2022.2
- Parrot security 5.0.1
Examples of How To Use
The program has 2 parameters:
The first parameter “-i” to specify the name of the network card (without monitor mode). The second parameter “-m” to specify the attack mode (Handshake | PKMID | AAuth | DAuth | BFlood | ETwin).
The program has a help menu with the “-h” parameter.
❯ python3 wifiCrack.py
