How to Crack WPA2 WiFi Password Using Reaver (99%)


Today I am going to teach you how to easily hack WPA/WPA2-PSK enabled networks using Reaver. The targeted router should support WPS (WiFi Protected Setup) which is supported by most routers nowadays. WPS is an optional device configuration protocol for wireless access points which makes it really easy to connect.

WPS exists in most routers for easy setup process through the WPS pin, which is hard-coded into the wireless access point. Reaver takes the advantage of a vulnerability in WPS. Thanks to Craig Heffner for releasing an open-source version of this tool named Reaver that exploits the vulnerability. In simple terms, Reaver tries to bruteforce the pin; which will reveal the WPA or WPA2 password after enough time.

NOTE: This tutorial is for Educational Purposes Only!

What You’ll Need

You do not have to be a expert at Linux or at using a computer. The simple command-line (console ) will do it all. You may need a fair bit of time for this process and maybe also some luck. The brute force may take from 2 hours to more than 10 hours. There are various ways to set up Reaver, but here are the requirements for this guide.

  • Backtrack OS. Backtrack is a bootable Linux distribution with lots of pen-testing tools. You can use various other Linux distribution but I prefer Backtrack. If you don`t know how to install Backtrack then please check this link first.
  • Computer and wireless network card. I cannot guarantee this will work with all the internal wireless card. I recommend a external wireless card.
  • Patience. The process is simple but brute forcing the PIN takes time. So you have to be patient. Kicking the computer won’t help.

Let’s Get Started

Have a Backtrack OS ready for action.

UPDATE: Use Kali Linux instead of Backtrack. See Backtrack is dead – Long Live Kali Linux

Step 1: Boot into BackTrack

You can use any method to boot into Backtrack eg. from live CD, VMware, dual boot, etc. Boot it first into the GUI mode and open up a new console (command line) which is in the taskbar. Then boot into backtrack. During the boot process, BackTrack will prompt you to to choose the boot options. Select “BackTrack Text – Default Boot Text Mode” and press Enter.

After some time Backtrack will take you into a command line prompt where you should type startx and press Enter. BackTrack will boot will into Graphical User Interface (GUI) mode.

Step 2: Install Reaver (Skip this step if you are using BackTrack 5)

Reaver should be already installed in the Backtrack 5 but if you are using an older version of Backtrack or any other Linux distribution, you can install Reaver by using the steps below.

  1. First Connect your BackTrack to the internet. For WiFi connection go to Application > Internet > WICD Network Manager.
  2. Select your network and click connect and input your password if necessary, click OK and click CONNECT the second time.

Now that you are connected to internet, it’s time to install Reaver. Click the terminal icon in the menu bar. And at the console type the following:

apt-get update
apt-get install reaver

Now if everything worked fine you will get a freshly installed Reaver tool. If you are testing it in your own system, please go to WICD Network Manager and Disconnect yourself first!

Step 3 : Gather Information

Before launching the Reaver attack, you need to know your target wireless network name or BSSID. This is the series of unique letters and number of a particular router, and you will need its channel number too. To find this, make your wireless card go into monitor mode, and gather the required information from the access points. Let’s go.

First lets find your wireless card. Inside terminal or console, type:


Press Enter and you should see a list of interface names of different devices. There should be a wireless device in that list connected to BackTrack. Probably it may be WLAN0 or WLAN1.

Note: To connect your wireless network card into WMware, firstly, connect it to the USB. You will see a small USB icon that looks like the figure in the top right of VMware. Right-click on the icon and click connect. The USB sign will turn green and start to glow.

Enable monitor mode. Assuming your wireless card interface name is WLAN0, type this command in that same console.

airmon-ng start wlan0

This code will create a new monitor mode interface mon0 as in the screenshot below. Keep note of the code.

Search the BSSID of the Access Point(router) you want to crack. There are few ways to search for the Access Point BSSID, but I prefer to use the inbuilt Reaver search method which shows the list of WPS-vulnerable BSSIDs only.

In the console, type this following command and press enter:

wash -i mon0

You will see the list of wireless networks that support WPS and are vulnerable to Reaver as seen in the screenshot below. After few minutes you can stop the scan by pressing Ctrl+C.

Step 4: Let’s Start Cracking

I suggest you to try to crack the ones which have WPS lock disabled or say “NO” in WPS Locked column. It may also work if it says YES but I am not sure of that. For that, copy the BSSID of the target AP and also keep note of its channel. In the console, type the following then Enter:

reaver -i monitormode -c channel -b targetbssid -vv

In my case the monitor mode will be mon0 channel 1, targetbssid would be C8:3A:35:54:88:81

-vv is written to show the current statistic of the attack as a percentage completed, currently brute forcing PIN and so on; so we will type the following and enter:

reaver -i mon0 -c 1 -b C8:3A:35:54:88:81 -vv

Press Enter and you should see the attack process as in the screenshot below.

Please note that you will not get “Restore previous session…”  at this point, because I already tried to crack it,  and it’s prompting me to resume from that paused point.

Your progress will also be saved if you press Ctrl+C. It will then prompt you in the same way, if you again hit the command, and you can resume it from there.

Now just wait or have some coffee and let Reaver do its magic. It might take from 2 hours to 10 hours or more. There are 8 numeric digits of WPS, but the WPS authentication protocol cuts the pin in half and validates each half separately. Since the last digit of pin is a cheksum value, which can be calculated on the basis of previous value, there are 10^4=10,000 possible values for first half and then 10^3=1000 values for the last pin. So the WPS pin code is one of 11,000 possible pin codes. Some APs can check the WPS pin at the rate of 1 pin per second. Some take more so it depends upon the AP, and also the network connection.

When the PIN is successfully brute-forced, Reaver will show you the WPS PIN and the plain password of the AP like in the below screenshot.

I recommend you keep note of the WPS pin, so that if the password is changed again you can hack that in few seconds the next time by using the following process.

reaver -i (monitor interface) -b (BSSID) -c (channel) --pin=(8 digit pin) -vv


reaver -i mon0 -b 11:22:33:44:55:66 -c 1 --pin=12345678 -vv

So now the error part… as you might get a bunch of errors depending upon your conditions. You might get some timeout but that’s normal. If you are getting other errors, see the below Error Section.

Error Section:

  • If 10 consecutive unexpected WPS errors are encountered, a warning message will be shown. This may be a sign that the AP is rate limiting pin attempts. A waiting command can be issued whenever these warning messages appear. Use the following command:
reaver -i mon0 -b 00:01:02:03:04:05 --fail-wait=360
  • The default receive timeout period is 5 seconds. This timeout period can be set manually if necessary (minimum timeout period is 1 second):
reaver -i mon0 -b 00:01:02:03:04:05 -t 3
  • The default delay period between pin attempts is 1 second. This value can be increased or decreased to any value. Please note that 0 means no delay:
reaver -i mon0 -b 00:01:02:03:04:05 -d 0

Here ends the tutorial on how to crack wireless network easily using Reaver. Good Luck!

How to Crack WPA2 WiFi Password Using Reaver (99%)



Internet has become a daily need of peoples.. without it people think life is useless or whatever……

If you have a PC with a wireless network card, then you must have seen many networks around you. Sadly most of these networks are secured with a network security key.

Cracking those Wi-Fi passwords is your answer to temporary internet access. This is a comprehensive guide which will teach even complete beginners how to crack WEP encrypted networks, easily.

If it’s WPA2-PSK passwords you need to crack, you can use aircrack-ng..

  1. How are wireless networks secured?
  2. What you’ll need
  3. Setting up wireless Adapter
  4. Start Capturing
  5. Now the interesting part… CRACKING!

Step 1: How Are Wireless Networks Secured?

In a secured wireless connection, internet data is sent in the form of encrypted packets. These packets are encrypted with network security keys. If you somehow manage to get hold of the key for a particular wireless network you virtually have access to the wireless internet connection.

WEP (Wired Equivalent Privacy)

This is the most basic form of encryption. This has become an unsafe option as it is vulnerable and can be cracked with relative ease. Although this is the case many people still use this encryption.

Step 2: What You’ll Need

  • A compatible wireless adapter:

This is by far the biggest requirement.The wireless card of your computer has to be compatible with the software Aircrack. This ensures that the wireless card can go into monitor mode which is essential for capturing packets. Click here to check if your wireless card is compatible

  • Aircrack for Wi-Fi :

This software will be used to capture the packets from the desired network adapter. This software will be already installed in the OS.

  • Kali Linux OS:

Kali Linux OS is a most used operating system for hacking … u need to install it or run it live … it can be downloaded here.

  • A little patience is vital!!

Step 3: Setting up wireless Adapter

  • After successful boot if kali linux …..
  • open terminal and type “airmon-ng”..
  • check if your device is listed there then you may proceed otherwise search a guide for drivers installation..
  • next step is to put device in monitor mode.
  • type in terminal “airmon-ng start wlan0”.. i used wlan0 .. maybe it is different in yours.

Step 4: Start Capturing

  • now its time for capture the packets.
  • type in terminal “airodump-ng mon0″… my monitor mode interface is on mon0 ..
  • it will start scanning .. and show you list .. press ctrl+c.. to stop process..
  • now start to capture by this command “airodump-ng -c 1 -w wep mon0” here -c is channel to capture .. -w is write packets to and wep is the name of file used to write in .. and mon0 is the interface..
  • now just be patient and wait for packets to collect atleast 20000data..

Step 5: Now the Interesting Part… CRACKING

  • After the packets are collected .. atleast 20000. we should start cracking along.
  • open new terminal and type “aircrack-ng -z wep-01.cap”… here -z is to crack … wep-01.cap is the file name we saved into -01 will be added auto.. so no worry and .cap is extension…
  • then your pass will be cracked
  • and enjoy the internet..
