Blog and dumb websites by the hacker known as "Alex" "work " by the hacker You might be having what seems like a genius idea, and that's “ wowee I should hack my neighbour's wifi because uhhhhhh”. 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. Hacking Wifi. Networks On. Windows. Zweep Books. Skype:Superhero +91 M4DH4CK3R. 7/9/ Kevin. This is my first.

This Linux tool will temporarily change the hard- etary wireless hacking tools available. There are two options for doing tools such as the Aircrack suite, Reaver, and Fern- this, one for bit tools, and one for bit Wi-Fi-Cracker. Wireshark -D print list of interfaces and exit comes with an easy-to-use interface. Fake Authentication2 www. This is a rather desirable feature which could perform a password reset with another new com- have been injected to purposefully delay malicious plex and longer password.

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. The handshake is connection of personal computer and wireless network, it is when network packet and personal computer packets meet each other. With handshake you do not need to be in wifi range anymore, you can hack password with handshake and wifi name you will learn this later.

Now you need to capture all the packets that are sent through the wifi router and all personal computers in network. So, now you know basics and ready to actually catch handshake.

First of all, change MAC address, enter monitor mode by typing in these commands on the photo: You can see that finally when I checked wlan0 mode it was monitor as you can see on the image. So you are ready to actually capture handshake, then it is very easy to hack wireless network by handshake and wordlist. Catching handshake Handshake packets are sent every time a client associates with the target AP. So to capture it we are going to capture every packets that are sent. This program lets us to sniff and capture the packets that are sent over the network.

This program is also preinstalled program. There are two step to catch handshake. Start airodump-ng on the target AP Access Point: The syntax is something like this: Wait for a client to connect to the access point, or deauthenticate a connected client if any so that their system will connect back automatically.

Follow these steps and when you will catch handshake your screen should like this: When you catch handshake you are ready to actually crack password.

Cracking any wireless network Now you have handshake and you need to download largest wordlist in the world to have change to hack password. You can download this wordlist from the following website: We are going to use aircrack-ng to crack the key. It does this by combining each password in the wordlist with access point name essid to compute a Pairwise Master Key PMK using pbkdf2 algorithm, the PMK is the compared to the handshake file.


The syntax looks like this: When the password will be hacked the screen should look like this: You already hacked WPA secured wireless network!!! It is time to secure our wireless network because as you know it is very simple to hack, and if someone will do, he can then capture packets that are sent over the network and analys them.

There will be your mail password, your social network password, card pin and so on. It is very dengerous to do not have secure wireless network. It is used for See here for the list of capture formats Wire- network troubleshooting. Packet Capture Figure 1.

How do we do that? All of the users will immedi- ately face a decision: The Wireshark software Once Wireshark is installed on your computer, you can begin capturing traffic. Each interface in that list is accompanied by a counter that continu- ously displays the number of Ethernet packets that have been observed. Beneath the usual arrangement of drop-down menus and icons, your display will be dominated by three large sections tiled on top of one another, each of which will span your entire display window from left to right.

You can re-size each of these 3 areas by left-clicking and dragging on the dividing horizontal boundaries between them. From top to bottom, these three sections are:.

You can check whether your password has been stolen by hackers and published by browsing to https: This password would let you prove that you are your neighbour when talking to their ISP.

You can cancel their internet all together. You can see their billing information. You are them. First you open up the popular hacking software, Google Chrome, and go to Oh no!
