c41n - an automated Rogue Access Point setup tool.

c41n provides automated setup of several types of Rogue Access Points, and Evil Twin attacks. c41n sets up an access point with user-defined characteristics (interface, name, and channel for the access point), sets up a DHCP server for the access point, and provides the user with abilities of HTTP traffic sniffing, or Captive Portal setup with credential sniffing.

Installation:

The installation consists of cloning the repo, running a script that will install dependencies, or install them manually, and making c41n executable. Installation script works with apt and Pacman package managers (Debian and Arch only).

# git clone https://github.com/MS-WEB-BN/c41n/
# cd c41n
# sudo bash install.sh
# sudo chmod +x c41n

Dependencies can also be installed manually (without the script) with apt-get package manager (Debian and Debian based distributions):

# sudo apt-get install net-tools hostapd dnsmasq tcpflow

and pacman (Arch and Arch-based distributions):

# sudo pacman -Sy net-tools hostapd dnsmasq tcpflow

Usage:

c41n can be run in interactive, and quick mode.

To run c41n in interactive mode:

# ./c41n

Quick mode:

Start Rogue AP:

# ./c41n <AP interface> <internet connection interface> <AP name> <AP channel>

Start Rogue AP + sniffing HTTP traffic:

# ./c41n sniff <AP interface> <internet connection interface> <AP name> <AP channel>

Start Rogue AP + captive portal:

# ./c41n captive <ap interface> <internet connection interface> <AP name> <AP channel> <redirection parameter>

Redirection parameter can have the following values:

0: Redirects only predefined domains.
1: Redirects all traffic.
domains_file: Redirects predefined domains + domains from specified file (separated by new line).

Examples:

[1] Start Rogue AP on wlan0 interface, route traffic from eth0 interface, AP name: 'AP', AP channel: '1'

# ./c41n wlan0 eth0 AP 1

[2] Start Rogue AP and sniff HTTP traffic on wlan0 interface, route traffic from wlan1 interface, AP name: 'Access_Point', AP channel: '6'

# ./c41n sniff wlan0 wlan1 Access_Point 6

[3] Start Rogue AP with a captive portal on wlp6s0 interface, redirect default domains and domains from custom file (/home/name/Documents/domains.txt), route traffic from eth1 interface, AP name: 'router', AP channel: '9'

# ./c41n captive wlp6s0 eth1 router 9 /home/name/Documents/domains.txt

Contribution note:

Each of the scripts/tools/programs hosted here is made as a part of MS-WEBs cybersecurity courses, aimed toward beginners, therefore are purely educational and/or demonstration, and are meant to stay that way, even if the wider audience and real-world usage are reached. All pauses present in code are there so that the user can read the output, so the action that is running is understood.

All pull requests removing such pauses, or parts of the output are against the educational purpose, and will not be accepted.

To remove sleeps from c41n use:

sed -i '/sleep/d' ./c41n
