WiFi Hacking : Hide identify, become untraceable
In hacking very important thing it to be untraceable. To be able to
hack something is nothing without hiding your identify. For example,
imagine that you hacked someones wifi and did not hide identify, in few days
police will analysis wifi router and there will be your computer information
and finally they will find you and throw into prison. So very important part of
entire hacking to hide identify and make hack untraceable. In this chapter you
going to learn about how to be anonymous, hide identify and how to become
fully untraceable.
What is mac address?
A MAC address (media access control address) is a unique identifier
assigned to network interfaces for communications on the physical network
segment. Every computer device have different MAC address. The MAC
address is a built-in every computer device when it is created. When
computer starts, operation system reads from hardware device. When you are
connected to the wireless network, it sends packets to you and then your
computer converts these information to websites, movies, images… Imagine
that two computers are connected to the wireless network, first computer
wants website google.com, and the second computer wants amazon.com,
network sends packets to these computers, but how do these computers know
what packets ignore and what packets to recive? Computers identify packets
to recive or ignore by MAC address, when the network is sending packet to
computer, it also writes in packet the MAC address of the computer it is
sending. that is the way how wireless networks and computers are connecting
each other. So, if you do not change your ip and hack someones wireless
network, you let them to investigate your identify by analysing network
history.
How to hide MAC address?
You may think that how you can change MAC address if computer
reads it from hardware? You are not going to make modification on
hardware, you going to change RAM. When the computer starts, MAC
address loads in RAM and we going to change already loaded MAC address..
So, when you change your MAC address police will find your fake MAC address and they will not be able to trace hacker. Now you have basic
information about what is MAC address, dangers of hacking without
changing MAC address, how police can trace you, how we can change it.
Change MAC address by Kali
Kali has already installed program called “macchanger” which lets us
to change loaded MAC address in RAM. Open VirtualBox, start kali virtual
machine and open terminal. We need to stop our wireless card to change the
MAC address. Type in “ifconfig wlan0 down”. The ifconfig is a program,
wlan0 is our wireless card and the down is action what we want to do. So,
this command will stop every wireless service and it is necessary to stop
network card before changing the MAC address. Then type in the following
command “macchanger --help”.This command tells Kali to call macchanger
and show help. There is program usage instructions. In my case, I will use
random MAC address by entering “macchanger –random wlan0”.macchanger
is program name –random is an option and wlan0 is wireless card. If
everything is correct the screen should look like this:
It shows you what was the permanent (built-in in network card)
MAC address and its corporation in brackets, and down it shows that there is
a new MAC address which does not have corporation. So, now we already
changed the mac address and we need to hack into anyones network. But you
are not ready for that now, because you do not know what is monitor mode
and how to use it. In the next chapter you will learn what monitor mode is
and how to use it with Kali.
