This is a brief walk-through tutorial that illustrates how to crack Wi-Fi networks that are secured using weak passwords. It is not exhaustive, but it should be enough information for you to test your own network’s security or break into one nearby. The attack outlined below is entirely passive and it is impossible to detect provided that you don’t actually use the password that you crack. An optional active deauthentication attack can be used to speed up the reconnaissance process and to get the handshake value.

Have aircrack-ng utility installed. If aircrack-ng is not installed in your Linux machine, then you can easily install it via below command: sudo apt-get install aircrack-ng Now first step is to recognize your wireless adapter by typing “ iwconfig” in your terminal. Here you can see, wlan0 is your wireless interface and it tells that it supports 802.11, ESSID is off and mode is managed etc. Now second step is to use Aircrack-ng which converts your wireless card into promiscuous monitor mode, it means it can see and receive all network traffic. Here ng means New Generation, because aircrack-ng replaces older suite called aircrack that is no longer supported. Now to start the monitor mode, just type “ airmon-ng start wlan0“, which converts your wlan0 into wlan0mon. The next tool is airodum-ng which enables us to capture packets of our specifications.
Start listening to broadcast by nearby wireless routers using your monitor interface by typing “ airodump-ng wlan0mon” in your same terminal. You should see the output similar to above screen. For the purposes of this practical, we will choose to crack the password of our network, “ Chetan Soni“. Remember the BSSID MAC address and channel (CH) number as displayed by, as we will need them both for the further steps.
So Our BSSID address is C4:F0:81:A1:0C:99 and Channel No is 11. As we can see in the screenshot above, airodump-ng displays all of the APs (access points) within range with their BSSID (MAC address), their power, the number of beacon frames, the number of data packets, the channel, the speed, the encryption method, the type of cipher used, the authentication method used, and finally, the ESSID.
Now next step is to capture a 4-way handshake because WPA/WPA2 uses a to authenticate devices to the network. You don’t have to know anything about what that means, but you do have to capture one of these handshakes in order to crack the network password. These handshakes occur whenever a device connects to the network, for instance, when your neighbor returns home from work. To capture 4-way handshake, type “ airodump-ng -c 11 –bssid C4:F0:81:A1:0C:99 -w yeahhub wlan0mon” in your terminal. Here -c stands for Channel, –bssid stands for Mac Address and -w stands for writing the packets into file. You should see the output similar to above screen.
Now here you can see in top right corner of above screen, there is no handshake so to get the handshake value instantly, we’ll use deauthentication method in which we’ll forced to send the malicious deauthentication packets to the target for reconnect. To deauthentication the target, type “ aireplay-ng -0 2 -a C4:F0:81:A1:0C:99 -c 84:10:0D:9E:A1:CD wlan0mon” in another terminal. Aireplay-ng is another powerful tool in our aircrack-ng arsenal, and it can be used to generate or accelerate traffic on the AP. This can be especially useful in attacks like a deauth attack that bumps everyone off the access point, WEP and WPA2 password attacks, as well as ARP injection and replay attacks. Here -a stands for BSSID address of the target and -c stands for station address.
A deauth attack sends forged deauthentication packets from your machine Nto a client connected to the network you are trying to crack. These packets include fake “ sender” addresses that make them appear to the client as if they were sent from the access point themselves. Upon receipt of such packets, most clients disconnect from the network and immediately reconnect, providing you with a 4-way handshake as shown below. You can optionally broadcast deauth packets to all connected clients with “ aireplay-ng -0 2 -a wlan0m0n“. So here, our handshake is “ C4:F0:81:A1:0C:99“. Once you’ve captured a handshake, press CTRL +C to quit airodump-ng. You should see a.cap file wherever you told airodump-ng to save the capture (likely called yeahhub-01.cap).
We will use this capture file to crack the network password. Now the final step is to crack the password using the captured handshake. If you have access to a GPU, we highly recommend using hashcat for password cracking. Method 1 – GPUHASH.me You can also use a website through which you simply need to upload your.cap file by clicking on Add new task.

In 2nd step, click on Next Now select the Basic WPA search package and fill out your email address and then click on SEND. At the end, you’ll get a task id where you can easily monitor your status whether your password they cracked or not. Method 2 – OnlineHashCrack You can also upload your.cap file into website along with your email address and then submit. Here you can upload the.cap file of maximum size is 20MB only. Method 3 – Naive-Hashcat Before to crack the password using, we need to convert our.cap to the equivalent hashcat file format.hccapx.
You can do this easily by either uploading the.cap file to or using the tool directly. You can also use website to convert the.cap file into.hccapx file. You can also use utility which is an open source script which you can download it through github by typing “ git clone After downloading the hashcat, go into /src directory and type “ make” command to compile the package. Now run the following command to convert the.cap file into.hccapx format using hashcat. Command:./cap2hccapx.bin Now copy the.hccapx file to root because we need this file with naive-hashcat script. Now to install naive-hashcat package, type “ git clone Download the dictionary file by typing “ curl -L -o dicts/rockyou.txt Now type “ HASHFILE=./yeahhub.hccapx POTFILE=yeahhub.pot HASHTYPE=2500./naive-hashcat.sh “.
Naive-hashcat uses various dictionary, rule, combination, and mask (smart brute-force) attacks and it can take days or even months to run against mid-strength passwords. The cracked password will be saved to yeahhub.pot, so check this file periodically. Once you’ve cracked the password, you should see something like this as the contents of your pot file. E30a5a57fc00211fc9fcc3:9c5c8ec9abc0:acd1b8dfd971:Chetan Soni:hackitnow Aircrack-ng can be used for very basic dictionary attacks running on your CPU. Before you run the attack you need a word list.
Now copy the same dictionary file into root by typing below command: Note, that if the network password is not in the word file you will not crack the password. To crack the password using aircrack-ng, type “ aircrack-ng -a2 -b C4:F0:81:A1:0C:99 -w dictionary.txt yeahhub-01.cap“. If the password is cracked you will see a KEY FOUND! Message in the terminal followed by the plain text version of the network password as shown below: Yippe, we got the key!
Much of the information presented here was gleaned from. Thanks also to the awesome authors and maintainers who work on Aircrack-ng and Hashcat.

The WiFi Protected Setup protocol is vulnerable to a brute force attack that allows an attacker to recover an access point’s WPS pin, and subsequently the WPA/WPA2 passphrase, in just a matter of hours. This is something that I’ve been testing and using for a while now, but Stefan over at beat me to publication. Such is life. ? Stefan’s code isn’t quite ready for release yet, so I’ve open-sourced, my WPS attack tool. Reaver is stable and has been tested against a variety of access points and WPS implementations. Usage is simple; just specify the target BSSID and the monitor mode interface to use: # reaver -i mon0 -b 00:01:02:03:04:05 For those interested, there is also a commercial version available with more features and speed improvements.
So I got the thing compiled, on linux. And it looks like it isn’t merely tied to linux (that’s what you’re using pcap for, because it provides portable capturing?) but more or less tied to your computer. You really should try and compile it on a different unix, fix all the includes linux silently adds but other unices don’t, heck even run that README through a text-formatter set to less than 80 characters wide, do some cross-testing and all that. Some sort of verbose reporting would be nice too. I just ran the thing for a night on two different wifi interfaces presumably in monitor mode (let kismet do the heavy lifting there) but all it did was say once “waiting for beacon” and sit there until eternity.
Kismet sees beacons, your software doesn’t. Well, useful. As much as I dislike the hype around python, I think I’ll wait for Stefan’s code as it looks like having a better shot at actually working on systems not equal to the author’s. I’m running -vv, but it seems I may have been blacklisted from the AP. Reaver tried about 2% of pins before i began recieving timeouts.
Now, all I get is timeouts (WARNING: Recieved timeout occured) from this particular AP. I tried giving it a few minutes to recover, but nothing changed. I changed my HW address to something different, thinking that may solve it and allow me to continue the brute force, but no beans. I can still associate with the AP, so it seems the device is up, but perhaps I’ve exhausted the PIN attempts maybe?
I’m letting it sit for about a half hour and then I’ll be trying again. I’ll let you know more specifics then. Hi Craig, Thanks for your tool, I used by i have this problem: Any idea?
Perhaps the router is not vulnerate?? Hi Craig, I follow your recomendation, I put my wiifi card more near to de AP. I have a (hopefully not stupud) question. In Stephan Viehbock’s white paper on this, it says this: “An attacker can derive information about the correctness of parts the PIN from the AP´s responses. If the attacker receives an EAP-NACK message after sending M4, he knows that the 1st half of the PIN was incorrect.
If the attacker receives an EAP-NACK message after sending M6, he knows that the 2nd half of the PIN was incorrect. This form of authentication dramatically decreases the maximum possible authentication attempts needed from 10^8 (=100.000.000) to 10^4 + 10^4(=20.000). As the 8th digit of the PIN is always a checksum of digit one to digit seven, there are at most 10^4 + 10^3 (=11.000) attempts needed to find the correct PIN.” I’ve noticed, using Reaver, that in the PIN attempts the second half of the PIN is reused quite frequently, sometimes 3 times out of 5 in a row. Is this because the the second half of the PIN cannot be tested until the 1st half has been successfully identified? After re-reading the paper I think this is the case, but I was hoping for confirmation.
I have a question about walsh/wash: after probing about 30 APs with WPA/WPA2 enabled, I found that no-one of them has WPS. My router has WPS, but no configuration at all in the panel (it’s an ISP-provided), and I am sure only about the button-enabled WPS, unsure about external registrar. By the way, I’m pretty sure that two routers in my range support it. They also respond to reaver’s attempts, but they don’t show up in wash’s output.
What may be happening? Am I doing wrong? My card’s driver are patched for injection and I use it seamlessly for other WiFi tests. Reaver/walsh works great on Sabayon Linux with a Realtek-chipset card I bought for about $13. My roommate was bitching about high Internet bills and blamed me for the bills. I have a wired connection and I.do.
use Torrents a fair bit. My roommate uses a wireless connection (despite being less than 20 feet from the router, as the crow flies) and insisted I was the cause of the high bill, but I know damned well I wasn’t responsible. We have another roommate who watches YouTube.endlessly., but I got the blame. “And, you have an unnecessary wireless network, in a household where not one of us uses wireless devices.” “Dude, nobody can hack it because I have a very long and complicated password! I used a car’s VIN number!” Yeah, well, his Pontiac’s VIN, read through the windshield, wasn’t it. Reaver did it. “987654321abc” was his super-complicated password.
Jesus, a password guessing program might have done it. Reaver cracked it in about 4 hours. He no longer bitches at me. Even admitted that I know more about computers than he does (my degree in Electrical Engineering from a Canadian University kind of trumps his time spent at the counter of a car-rental company, I would have thought).

You’ve made me aware how vulnerable I am and I just replaced my router because of the knowledge I gained with this program.

Using version 1.4 to crack a Netgear WPA secured router.
Man, it is taking FOREVER. The problem with Reaver is when you start to attack routers with timeout values.
It will get into a situation where there is a minimum timeout after so many attempts before it lets reaver rechallenge WPS. After 10 failed attempts, I set -x = 250 seconds. That’s over 4 minutes. So, it has taken me over 8 hours just to get to 18% of the pins. Worst case estimate, is it takes about 45+ hours to finish. That’s a lot better than a straight dictionary attack, but it is way worse than 10 hours. Don’t delude yourself into thinking Reaver will crack WPA in 10 hours or less.
Also, lots of routers do not have WPS enabled or supported. For the newbies, you should use wash to figure out which AP’s and routers support WPS. Finally, some routers will lock down WPS after too many failed attempts.
So, just so people know, Reaver is not the end alls. It is just another tool in the lockpicker’s arsenal. Personally, I think a better way would be to do a middle man attack.
Yes, if the AP rate limits you the attack will take longer. Most AP’s don’t, but Netgear is the exception. And yes, some completely lock you out after X number of attempts. I don’t think anyone is deluding themselves here, this is all documented behavior, and why reaver has options like -x. Yes, a lot of AP’s don’t support WPS, but they are typically fairly old APs. Pretty much anything made within the last 4-5 years will have WPS support on by default (it’s very rare to see people actively disable WPS). The number of WPS enabled APs will only rise in the future.
Good luck with a MITM attack. If that actually worked people would have been doing it for years now. 24 hours working and nothing just this messages, any help?

If so, then run airmon-ng wlan0 it will set the card to monitor mode then run reaver this is my code: reaver -i mon0 -b -S -N -a -c -vv -r 17:30 -d 0 sometimes it fails to associate so I run airmon-ng mon0 and then run reaver again. My problem is that I am not able to automate the process, I have to manually re associate the AP which means I have to be looking at it the whole time:/ Unless someone has a script or something that could help me out. Very much Appreciated it.
