wifijam

An 802.11n beacon frame transmission program.

Wifijam is a program that sends 802.11n beacon frames to announce fake Wi-Fi access points. These fake access points will have passwords and can not be really connected to.

This program comes with two versions: a Scapy version and an ESP8266 version.

The Scapy version requires a Linux computer with a Wi-Fi card supporting the "monitor" mode, as well as Python 3 and scapy-python3.

The ESP8266 version requires a development board with an ESP8266 Wi-Fi chip (usually less than $9), along with the Arduino IDE with ESP8266 plugins.

Usage

Before you start

Edit the source code, modify ssid_list for a list of SSIDs you wish to send.

Then modify SSID_DUPLICATES for the number of duplicates for each SSID.

SSID_DUPLICATES must be no more than 10. SSID_DUPLICATES × the length of ssid_list should be no more than 80.

Scapy version (using iw)

Type:

sudo ip link set dev wlan0 down
sudo iw dev wlan0 interface add wlan0mon type monitor
sudo ./wifijam.py wlan0mon

… where wlan0 is the device name of your Wi-Fi card. Change them according to your situation.

After you finished, type:

sudo iw dev wlan0mon del
sudo ip link set dev wlan0 up

Scapy version (using aircrack-ng)

Alternatively, if iw does not work for you, try airmon-ng:

sudo airmon-ng start wlan0
sudo ./wifijam.py wlan0mon

… where wlan0 is the device name of your Wi-Fi card, wlan0mon is the monitor name given by airmon-ng. Change them according to your situation.

After you finished, type:

sudo airmon-ng stop wlan0mon

ESP8266 version

Connect your development board to the Arduino IDE. Open wifijam.ino, then click Sketch → Upload.

You might need to press the "Flash" button if your development board has one.

Refer to the ESP8266 documentation if you have any problems.
