Wifite : Hacking Wifi The Easy Way : Kali Linux

Wifite

While the aircrack-ng suite is a well known name in the wireless hacking , the same can't be said about Wifite. Living in the shade of the greatness of established aircrack-ng suite, Wifite has finally made a mark in a field where aircrack-ng failed. It made wifi hacking everyone's piece of cake. While all its features are not independent (eg. it hacks WPS using reaver), it does what it promises, and puts hacking on autopilot. I'm listing some features, before I tell you how to use wifite (which I don't think is necessary at all, as anyone who can understand simple English instructions given by Wifite can use it on his own).

Features Of Wifite

• Sorts targets by signal strength (in dB); cracks closest access points first
• Automatically de-authenticates clients of hidden networks to reveal SSIDs
• Numerous filters to specify exactly what to attack (wep/wpa/both, above certain signal strengths, channels, etc)
• Customizable settings (timeouts, packets/sec, etc)
• "Anonymous" feature; changes MAC to a random address before attacking, then changes back when attacks are complete
• All captured WPA handshakes are backed up to wifite.py's current directory
• Smart WPA de-authentication; cycles between all clients and broadcast deauths
• Stop any attack with Ctrl+C, with options to continue, move onto next target, skip to cracking, or exit
• Displays session summary at exit; shows any cracked keys
• All passwords saved to cracked.txt
• Built-in updater: ./wifite.py -upgrade

I find it worth mentioning here, that not only does it hack wifi the easy way, it also hack in the best possible way.  For example, when you are hacking a WEP wifi using Wifite, it uses fakeauth and uses the ARP method to speed up data packets (I wrote a full length post about something which it does automatically!).

Hacking WEP network

If you've followed my previous posts on Hacking Wifi (WEP), you know there's a lot of homework you have to do before you even start hacking. But not here. With Wifite, its as easy and simple as a single command.

wifite -wep

You might even have used the command

wifite

If you see any error at this stage move to the bottom of the page for troubleshooting tips. If your issue is not listed please comment. We reply within a day.
The -wep makes it clear to wifite that you want to hack WEP wifis only. It'll scan the networks for you, and when you think it has scanned enough, you can tell it to stop by typing ctrl+c. It'll then ask you which wifi to hack. In my case, I didn't specify -wep so it shows all the wifis in range.

 You can also select all and then go take a nap (or maybe go to sleep). When you wake up, you might be hacking all the wifi passwords in front of you. I typed one and it had gathered 7000 IVs (data packets) within 5 mins. Basically you can except it to hack the wifi in 10 mins approx. Notice how it automatically did the fake auth and ARP replay.

Here are a few more screenshots of the working of Wifite, from their official website (./wifite.py is not something that should bother you. You can stick with the simple wifite. Also, specifying the channel is optional so even the -c 6 was unnecessary. Notice that instead of ARP replay, the fragmentation attack was used, using -frag) -

 Hacking WPS wasn't fast (it took hours), but it was easy and didn't require you to do anything but wait.

 Note, the limitation that many reader on my blog are beginners forbid me from introducing too many attacks. I made a tutorial about ARP replay attack, and that too was detailed as hell. However, Wifite makes it possible for you to use any method that you want to use, by just naming it. As you saw in the screenshot above, the fragmentation attack was carried out just by typing -frag. Similarly, many other attacks can be played with. A good idea would be to execute the following-

wifite -help

This will tell you about the common usage commands, which will be very useful. Here is the list of WEP commands for different attacks-
    WEP
-wep         only target WEP networks [off]
-pps <num>   set the number of packets per second to inject [600]
-wept <sec> sec to wait for each attack, 0 implies endless [600]
-chopchop   use chopchop attack      [on]
-arpreplay   use arpreplay attack     [on]
-fragment   use fragmentation attack [on]
-caffelatte use caffe-latte attack   [on]
-p0841       use -p0841 attack        [on]
-hirte       use hirte (cfrag) attack [on]
-nofakeauth stop attack if fake authentication fails    [off]
-wepca <n>   start cracking when number of ivs surpass n [10000]
-wepsave     save a copy of .cap files to this directory [off]

As you can see, its the same thing as is there on the help screenshot. Play around with the attacks and see what you can do. Hacking WPA without WPS wouldn't be that easy, and while I don't usually do this, I'm providing a link to an external website for the tutorial . This is the best WPA cracking tutorial I've seen, and I can't write a better one. It's highly detailed, and I'm just hoping I don't lose my audience to that website. Here is the tutorial - Cracking Wifi WPA/WPA2 passwords using pyrit cowpatty in Kali Linux

Troubleshooting

Wifite quits unexpectedly, sating "Scanning for wireless devices. No wireless interfaces were found. You need to plug in a wifi device or install drivers. Quitting."

You are using Kali inside a virtual machine most probably. Virtual machine does not support internal wireless card. Either buy an external wireless card, or do a live boot / side boot with Windows. Anything other than Virtual machine in general.

Speeding Up WEP Hacking In Kali

Now if you have followed the basic WEP hacking tutorial, and have also read the basic troubleshooting guide, then you are ready to proceed to the stage where you follow an intermediate level hacking tutorial. In this tutorial, we will look at the intricate details of what is happening and approach the complicated methods and concepts.




To start with, I'll address a common question which was asked on my previous posts.

14 March 2014 19:28

i couldn't find any wlan when i write ifconfig in terminal

1. 
   
   
   
   
   Are you using Kali Linux on a virtual machine. Please note that a wireless adapter can only be used by only one machine at a time. Your host machine has access to the wireless adapter, not the virtual machine. This question has been discussed at length on superuser forums. The conclusion is that you can't directly connect internal wifi card using any Virtual machine software-
   "Unfortunately no virtualization software allows for direct access to hardware devices like that.
   
   Compare VirtualBox with VMware Fusion and Parallels for Mac. All 3 of those programs behave the same way. The only devices that can be directly accessed are usb devices. Everything else is abstracted though the virtualization engine. (Though you could argue that the vm has lower level access to cd rom's and storage devices).
   
   I wish I could give you a better answer, than simply to buy a usb wireless card."
   Basically you have to buy an external wireless card. They aren't very expensive. I personally use two of them myself. If you want to see what I use, take a look here, http://beginnnerhacking.blogspot.in/2014/02/creating-dummy-wifi-for-hacking.html

So basically you have 2 choices. First, you can buy a new external wireless adapter (no referral links here). Secondly, you can side install Kali with Windows or run it via a USB. A virtual machine can only use computer hardware if it is externally connected via USB. Now there is another catch here. The internal adapters, almost all of them, don't support injection. This is extremely important for speeding up wireless hacking. So if you really want to go in depth of wireless hacking, then its time to buy an external adapter or two (the more the better). If that's not a possibility, you might want to spend hours trying to get a driver which might make your internal adapter support injection (I don't know anyone who succeeded in this, but it might be possible).

Kali Linux

I don't know why it needs mention here, but still, if you don't have Kali Linux (or Backtrack) installed yet, you will have to install it before you can start this tutorial. Here is the tutorial on Kali Linux hacking.

Check Injection Support

Aircrack-ng has a comprehensive article related to checking injection support. You might check their website out for it. I am just providing the commands which will be enough to find out whether injection is working or not. 

airmon-ng start wlan0  [or wlan1]

(Puts your wireless adapter in monitor mode. From now we'll refer to wlan0/wlan1 as mon0

airserv-ng -d mon0

 aireplay-ng -9 127.0.0.1:666

This basically sets up a temporary server sort of thing that is waiting for you to test your injection capabilities. The second command actually tries to inject the server, and succeeds. 127.0.0.1 is the IP which is reserved for loopback. It is always used when you are carrying out some command on yourself. 666 is the port we are using. Most of the time, what follows an IP and a colon is the port. The general form is somewhat like IP:port. So finally you have checked your injection capabilities, and the last line - "Injection is working!" should bring a smile to your face. If not, you'll have to buy a card which supports injection, or see some forum posts which will help you figure something out.

Check Signal Strength

While the basic hacking methods from the previous post don't have any real strength restriction, you need to be physically close to the access point in order to inject packets. There is information regarding the same in the same aircrack-ng tutorial. Again, I'm gonna summarize what you have to do here.

First, we will use airodump-ng mon0 to see the list of networks in range. See the one you want to hack.

Airodump-ng lists the networks in range.

Now we will hack the digisol network. Make a note of the BSSID of the network you want to hack.  A good practice is to store all the information gathered in any text editor. We should, at this stage, take a note of following:-

• ESSID -  DIGISOL
• BSSID - 00:17:7C:22:CB:80
• CH (channel) - 2
• Mac address of genuine users connected to the network:
• Interface : wlan1 - referred to as mon0

You should gather the equivalent information for the network you will be working on. Then just change the values whenever I use them in any of the commands

Note : We need at least one user (wired or wireless) connected to the network and using it actively. The reason is that this tutorial depends on receiving at least one ARP request packet and if there are no active clients then there will never be any ARP request packets.

Now, to check whether the signal strength will be sufficient, we will simply execute the following code-

airodump-ng [interface] -c [channel]

airodump-ng mon0 -c 2

This will make the wireless card only read packets in the channel no. 2, on which our target network is.

Now to test the network, type the following code-

aireplay-ng --test -e DIGISOL -a 00:17:7C:22:CB:80 mon0 

 The last time we checked whether the wireless card had the capability to inject packets. We tested it on our own computer. This time, we actually injected packets into the target computer. If this worked, then it's pretty good news, and it means that you are most probably going to be able to hack this network. The last line 30/30 : 100% determines how good the strength of the signal is. A very high percentage is a good sign, and 100 is ideal.

Capture Packets

Now we have already run airodump-ng a couple of times. However, this time we will pass the -w command which will instruct airodump-ng to save the output to a file.

airodump-ng -c [channel] --bssid [bssid]-w [file_name] [interface]

airodump-ng -c 2 --bssid 00:17:7C:22:CB:80 -w dump mon0

 Now the output will be saved in a file  dump-01.cap
Now we can keep this terminal running and it will keep saving the packets.  [In the previous tutorial we did only 2 things, capture the packet, i.e this step, and crack it, i.e. the step we are going to do last. While it makes our work easier to just follow two steps, it also makes the process much more time consuming, since we are simply a passive packet listener, who is not doing anything]

Speeding Things Up

Fake Authentication

Now to speed things up, we will inject the network. We will thus obtain ARP packets. These packets will fill up the data column of our airodump-ng capture, and data is what will help us obtain the password. As soon as we have 10000 data packets, we can start attempting to get the password using aircrack-ng.

Now to make the AP pay attention to your injected packets, you either have to be a connected client, or have to pretend to be one. You can either mask your mac address to one of the already connected clients, or use the fake authentication feature. We will do the latter. (If you see an error like the AP is on channel x and mon0 is on channel y then go to the bottom of the post for troubleshooting)

aireplay-ng -1 0 -e DIGISOL -a  00:17:7C:22:CB:80 mon0

Authenticated and capturing packets

 ARP request replay mode

ARP packets are your best bet at getting a lot of IVs or data. Without IVs you can't hack a network. Enter the following code to make aireplay-ng listen to the AP for ARP packets, and inject them as soon as they find one. This will create a lot of data very fast. This is the real speeding step. 

aireplay-ng -3 -b [BSSID] mon0

This is what the final code will look like-

aireplay-ng -3 -b  00:17:7C:22:CB:80 mon0

This is what it'll look like in the beginning

 Now you'll have to wait for some time till it gets an ARP request. As soon as it gets one, the terminal will sort of explode. And the data packets will start filling in with Godspeed. Now this is the part where an active user on the network is absolutely necessary.

Slow start

Everything got fine after some time

After some time I had enough packets to crack almost any network

The data filled in VERY fast

The video shows how fast the IVs flowed in after ARP injection started.

Cracking the network

Cracking the network is as easy as typing the following into the console

aircrack-ng name_of_file-01.cap

In our case, the command will be

aircrack-ng dump-01.cap

 After pressing enter, you will have a list of networks and you'll be prompted to select which one of them to hack. In my case there was just one network, so I couldn't get that screen, or a screenshot. The password was cracked in less than a second.

I have blurred out the password and some random stuff.

So finally you have obtained the password of the network you were trying to hack.

Troubleshooting

A person commented on another wireless hacking post. This is the problem he faced.

whenever i try to use aireplay-ng, with the options, always fail saying that mon0 is in channel -1 and the target is in other channel. How can i fixed this? i looked a lot for a real answer but nobody know what is this.

This is a possible solution

Okay, try the following-
1) When you start the monitor mode, specify the channel - 
usage: airmon-ng [channel or frequency]
Your code : airmon-ng start wlan0 6
Substitute 6 with the required channel.
2) While starting airodump, specify the channel
airodump-ng mon0 -c 6

I was facing this problem when my mon0 kept hopping from one channel to the other, and the second step alone solved my problem. If your airmon-ng assigns itself a fixed channel on its own will, without you even specifying it, then the problem might be more complicated. If the above steps don't solve the problem, take a look here - http://ubuntuforums.org/showthread.php?t=1598930
