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.

Another attack automating script : Fluxion

Wifite is cool and all, but doesn't do much against the invincible WPA-2 networks. Using a combination of evil-twin and man in the middle sort of attacks, fluxion tries to fool a client into giving you the key to the WPA-2 protected access point. Sounds interesting? Take a look.

Hacking Website with Sqlmap in Kali Linux

A screenshot from the SQLmap official website

In the previous tutorial, we hacked a website using nothing but a simple browser on a Windows machine. It was a pretty clumsy method to say the least. However, knowing the basics is necessary before we move on to the advanced tools. In this tutorial, we'll be using Kali Linux (see the top navigation bar to find how to install it if you haven't already) and SqlMap (which comes preinstalled in Kali) to automate what we manually did in the Manual SQL Injection tutorial to hack websites.




Now it is recommended that you go through the above tutorial once so that you can get an idea about how to find vulnerable sites. In this tutorial we'll skip the first few steps in which we find out whether a website is vulnerable or not, as we already know from the previous tutorial that this website is vulnerable.

Kali Linux

First off, you need to have Kali linux (or backtrack) up and running on your machine. Any other Linux distro might work, but you'll need to install Sqlmap on your own. Now if you don't have Kali Linux installed, you might want to go to this page, which will get you started on Beginner Hacking Using Kali Linux

Sqlmap

Basically its just a tool to make Sql Injection easier. Their official website  introduces the tool as -"sqlmap is an open source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers. It comes with a powerful detection engine, many niche features for the ultimate penetration tester and a broad range of switches lasting from database fingerprinting, over data fetching from the database, to accessing the underlying file system and executing commands on the operating system via out-of-band connections."

A lot of features can be found on the SqlMap website, the most important being - "Full support for MySQL, Oracle, PostgreSQL, Microsoft SQL Server, Microsoft Access, IBM DB2, SQLite, Firebird, Sybase and SAP MaxDB database management systems." That's basically all the database management systems. Most of the time you'll never come across anything other than MySql. 

Hacking Websites Using Sqlmap in Kali linux

Sql Version

Boot into your Kali linux machine. Start a terminal, and type -

sqlmap -h

It lists the basic commands that are supported by SqlMap. To start with, we'll execute a simple command
sqlmap -u <URL to inject>. In our case, it will be-

sqlmap -u http://testphp.vulnweb.com/listproducts.php?cat=1

Sometimes, using the --time-sec helps to speed up the process, especially when the server responses are slow.

sqlmap -u http://testphp.vulnweb.com/listproducts.php?cat=1 --time-sec 15

Either ways, when sqlmap is done, it will tell you the Mysql version and some other useful information about the database.

The final result of the above command should be something like this.

Note: Depending on a lot of factors, sqlmap my sometimes ask you questions which have to be answered in yes/no. Typing y means yes and n means no. Here are a few typical questions you might come across-

• Some message saying that the database is probably Mysql, so should sqlmap skip all other tests and conduct mysql tests only. Your answer should be yes (y).
• Some message asking you whether or not to use the payloads for specific versions of Mysql. The answer depends on the situation. If you are unsure, then its usually better to say yes.

Enumeration

Database

In this step, we will obtain database name, column names and other useful data from the database.

List of  a few common enumeration commands

So first we will get the names of available databases. For this we will add --dbs to our previous command. The final result will look like -

sqlmap -u http://testphp.vulnweb.com/listproducts.php?cat=1 --dbs

 So the two databases are acuart and information schema.

Table

Now we are obviously interested in acuart database. Information schema can be thought of as a default table which is present on all your targets, and contains information about structure of databases, tables, etc., but not the kind of information we are looking for. It can, however, be useful on a number of occasions. So, now we will specify the database of interest using -D and tell sqlmap to enlist the tables using --tables command. The final sqlmap command will be-

sqlmap -u http://testphp.vulnweb.com/listproducts.php?cat=1 -D acuart --tables

The result should be something like this -
Database: acuart
[8 tables]
+-----------+
| artists   |
| carts     |
| categ     |
| featured  |
| guestbook |
| pictures  |
| products  |
| users     |
+-----------+
Now we have a list of tables. Following the same pattern, we will now get a list of columns.

Columns

Now we will specify the database using -D, the table using -T, and then request the columns using --columns. I hope you guys are starting to get the pattern by now. The most appealing table here is users. It might contain the username and passwords of registered users on the website (hackers always look for sensitive data).

The final command must be something like-

sqlmap -u http://testphp.vulnweb.com/listproducts.php?cat=1 -D acuart -T users --columns

The result would resemble this-

Data

Now, if you were following along attentively, now we will be getting data from one of the columns. While that hypothesis is not completely wrong, its time we go one step ahead. Now we will be getting data from multiple columns. As usual, we will specify the database with -D, table with -T, and column with -C. We will get all data from specified columns using --dump. We will enter multiple columns and separate them with commas. The final command will look like this.

sqlmap -u http://testphp.vulnweb.com/listproducts.php?cat=1 -D acuart -T users -C email,name,pass --dump

 Here's the result

John Smith, of course. And the password is test. Email is email@email.com?? Okay, nothing great, but in the real world web pentesting, you can come across more sensitive data. Under such circumstances, the right thing to do is mail the admin of the website and tell him to fix the vulnerability ASAP. Don't get tempted to join the dark side. You don't look pretty behind the bars. That's it for this tutorial. Try to look at other columns and tables and see what you can dig up. Take a look at the previous tutorial on Manual SQl Injection which will help you find more interesting vulnerable sites.
