Wifijammer in python - Seven - 08-29-2014

WIFI JAMMER

I do not claim credit for the creation of this script.

I found a WiFi jamming script on github created in python and thought I would share. It effectively disables WiFi for anyone connected to a acces point within your wireless cards range in short it DoS's every ones wifi Biggrin

.

The script first detects the most powerfull wireless card on the attackers device and manipulates it so that it is ready for injection etc. Due to this factor it is required that the script be run as root. It will then hop channels 1 to 11 to identify access points a clients connected to those access points. The actual attack is done through deauthentication packets that are sent to both the client and the acces point

It is extremely simple to deploy and run, its only dependency being python scappy.

On Linux machines running a Debian based distro scapy can be installed through

Code:
sudo apt-get install python-scapy

In its simplest form the script can be executed through

Code:
python wifijammer.py

which will execute the previously mentioned process
WARNING THIS WILL KNOCK YOU OFF YOUR ACCESS POINT AS WELL

Advanced usage is rather simple here are some of my most frequentally used options:

Code:
python wifijammer.py -c 1

will only attack and deauth clients on channel 1

Code:
python wifijammer.py -s 00:00:00:00:00:00

will tell the script not to attack the mentioned MAC address

Here are all of the other options:

Code:
python wifijammer.py [-a AP MAC] [-c CHANNEL] [-d] [-i INTERFACE] [-m MAXIMUM] [-n] [-p PACKETS] [-s SKIP] [-t TIME INTERVAL]

All credit for this script goes to DanMcInerney

Here is the projects page: GitHub

I am in the process in modding the script myself, if you beat me to such a goal please post your modifications. I will be more than interested in seeing them and trying them out myself.

Interested to hear if this works. I only skimmed the post, regrettably.

The attack works on most networks. Prevention is based on a routers ability to detect malicious packets. However most of the routers that ISP's give out for free are vulnerable to this exploit. On a user end those who run a linux based OS could modify their sysctl settings in /etc/sysctl.conf

It's a neat idea sending deauth packets to knock off wifi, simple too. By the way, it's not really an exploit; it's basically a DoS attack.

I guess your right now that I think about it. Ill edit the post.

I don't think it will effect computers linked to the router by Ethernet. But if you have a strong enough wireless card then you can hit a lot of laptops and phones.

Your school uses WiFi?

Or you could just install a bigger antenna. Knocking out a LAN network is pretty easy.

Code:
Kali Linux > flood_router26 -F wlan0

Boom, network down. I do not condone illegal acts.

I'm going to run a test and see how well if at all this script does its magic over Ethernet as well

Yeah... it would suck if everyone had to plug ethernet cables into their computers/phones just to connect to the internet...
