Automated Wifi De-authentication attack

A Wi-Fi deauthentication attack is a type of denial-of-service attack that targets communication between a user and a Wi-Fi wireless access point.


As you can see, this type of attack is pretty powerful and difficult  to detect who is attacking. There are some tools for this attack like “aircrack-ng”(You can check the commands here).

So, basically the concept is the attacker broadcasts a wifi management “De-authentication” frame to victim’s to tell deauthenticate. It is like, “Hey client! can you please deauthenticate and authenticate”.  Then the client will reconnect to AP(Access Point). These type of frames are supposed to send by valid “AP” to its clients, but the attacker can mimic these frames and broadcasts in the network.

What is ONE Installer?

The ONE Installer is an  automated script to install software/packages for Ubuntu 14. My self wrote this automated script in Python 2.7. The reason is simple, every time I install Ubuntu OS, I need some packages/software to be installed. You knew some are pretty simple like “apt-get install curl”, but some packages/software needs some other additional tweaking like for “Eclipse” we need to create “eclipse.desktop” with some entry in “/usr/share/application”(You can see the steps in this blog). So, it is little bit pain full to do this every time. This automated script will install packages one by one and configures the software.

Port Mirroring with iptables

I have tested in Ubuntu 14 (I don’t know about other distros). As you know, sometimes port mirroring is useful for monitoring the network traffic for intrusion detection system,Passive probing, etc. Basically, it sends a copy of packet to destination which was received on the interface(depends on your configuration). And again depends on your need, you can use Netflow also.
