netattack- A Tool for Wireless Network Scan and Attack

The netattack.py is a python script that allows you to scan your local area for WiFi Networks and perform deauthentification attacks. The effectiveness and power of this script highly depends on your wireless card.

DE-AUTHENTIFICATION ATTACK

python netattack.py -deauth -b AB:CD:EF:GH:IJ:KL -u 12:34:56:78:91:23 -c 4 -mon
This command will obviously perform a deauthentification attack.
-deauth | –deauth
This parameter is a main parameter as well as scan. It is necessary to call if you want to deauth attack a certain target.
-b | –bssid
With -b you select the AP’s MAC-Address (BSSID). The -deauth parameter requires one or multiple BSSID’s
-u | –client
If you don’t want to attack the whole network, but a single user/client/device, you can do this with -u. It is not necessary.
-c | –channel
By adding this parameter, your deauthentification attack is going to be performed on the entered channel. The usage of -c is highly recommended since the attack will be a failure if the wrong channel is used. The channel of the AP can be seen by doing a WiFi scan (-scan). If you don’t add -c the attack will take place on the current channel.
The -mon or -i is necessary for this attack as well.

DE-AUTHENTIFICATION ATTACK ON EVERYBODY

python netattack.py -deauthall -i [IFACE]
When this command is called, the script automatically searches for AP in your area. After the search it start deauth-attacking all of the found AP’s. The -deauthall parameter only needs an interface to get it working. ATTENTION: If you want all of this attacks to be as efficient as possible, have a look at the following “ADVANCED”-section

ADVANCED

-p | –packetburst
This parameter is understood as the packetburst. Especially when you are targeting multiple AP’s or even performing a -deauthall attack, the command is a must have. It defines the amount of deauth-packages to send after switching the target. When not adding the parameter it is going to be set to 64 by default. But that is highly unefficient if you are attacking 4+ AP’s.
-t | –timeout
This parameter can be added to a -scan or -deauth. If it’s added to the -scan parameter it defines the delay while switching the channel. It is set to 0.75s by default, so it is waiting 0.75s on each channel to collect beacon frames. If it’s added to the -deauth parameter, it defines the delay between each packetburst. This can be used to decrease the intense of the attack or to attack the target(s) at a certain time.
-cf | –channelformat
This parameter can only be added to -scan. It shows a more detailed output while scanning. It’s mainly recommended when the location changes and with it the AP’s.
-a | –amount
This parameter can only be added to -deauth. It defines a certain amount of packetbursts to send. This can be used for taking down the WiFi for a certain time.
