You already know that if you want to lock down your Wi-Fi network, you should opt for WPA encryption because WEP is easy to crack. But did you know how easy? Take a look.
A Wi-Fi hacking software is a software program that will primarily enable you to crack Wi-Fi password of a nearby network. These software programs are designed to work for WPA, WPA2 and WEP. Some of them are open-source applications and work as good network analyzer as well as packet sniffer. 5 Steps Wifi Hacking – Cracking WPA2 Password Posted by Vishnu Valentino in Hacking Tutorial| 241 commentsVishnu Valentino in Hacking Tutorial| 241 comments.

Today we're going to run down, step-by-step, how to crack a Wi-Fi network with WEP security turned on. But first, a word: Knowledge is power, but power doesn't mean you should be a jerk, or do anything illegal. Knowing how to pick a lock doesn't make you a thief. Consider this post educational, or a proof-of-concept intellectual exercise.

Dozens of tutorials on how to crack WEP are already all over the internet using this method. Seriously—Google it. This ain't what you'd call 'news.' But what is surprising is that someone like me, with minimal networking experience, can get this done with free software and a cheap Wi-Fi adapter. Here's how it goes.
What You'll Need
Unless you're a computer security and networking ninja, chances are you don't have all the tools on hand to get this job done. Here's what you'll need:

Crack That WEP
To crack WEP, you'll need to launch Konsole, BackTrack's built-in command line. It's right there on the taskbar in the lower left corner, second button to the right. Now, the commands.

First run the following to get a list of your network interfaces:
The only one I've got there is labeled
ra0 . Yours may be different; take note of the label and write it down. From here on in, substitute it in everywhere a command includes (interface).

Now, run the following four commands. See the output that I got for them in the screenshot below.

If you don't get the same results from these commands as pictured here, most likely your network adapter won't work with this particular crack. If you do, you've successfully 'faked' a new MAC address on your network interface, 00:11:22:33:44:55. https://bagyellow897.weebly.com/google-play-music-for-mac.html.

Now it's time to pick your network. Run:
To see a list of wireless networks around you. When you see the one you want, hit Ctrl+C to stop the list. Highlight the row pertaining to the network of interest, and take note of two things: its BSSID and its channel (in the column labeled CH), as pictured below. Obviously the network you want to crack should have WEP encryption (in the ENC) column, not WPA or anything else.

Now we're going to watch what's going on with that network you chose and capture that information to a file. Run:
Where (channel) is your network's channel, and (bssid) is the BSSID you just copied to clipboard. You can use the Shift+Insert key combination to paste it into the command. Enter anything descriptive for (file name). I chose 'yoyo,' which is the network's name I'm cracking.

You'll get output like what's in the window in the background pictured below. Leave that one be. Open a new Konsole window in the foreground, and enter this command:
Here the ESSID is the access point's SSID name, which in my case is
yoyo . What you want to get after this command is the reassuring 'Association successful' message with that smiley face.

You're almost there. Now it's time for:
Best free sd card recovery software. Here we're creating router traffic to capture more throughput faster to speed up our crack. After a few minutes, that front window will start going crazy with read/write packets. (Also, I was unable to surf the web with the
yoyo network on a separate computer while this was going on.) Here's the part where you might have to grab yourself a cup of coffee or take a walk. Basically you want to wait until enough data has been collected to run your crack. Watch the number in the '#Data' column—you want it to go above 10,000. (Pictured below it's only at 854.)

Depending on the power of your network (mine is inexplicably low at -32 in that screenshot, even though the
yoyo AP was in the same room as my adapter), this process could take some time. Wait until that #Data goes over 10k, though—because the crack won't work if it doesn't. In fact, you may need more than 10k, though that seems to be a working threshold for many.

Once you've collected enough data, it's the moment of truth. Launch a third Konsole window and run the following to crack that data you've collected:
Here the filename should be whatever you entered above for (file name). You can browse to your Home directory to see it; it's the one with .cap as the extension.

If you didn't get enough data, aircrack will fail and tell you to try again with more. If it succeeds, it will look like this:

Problems Along the Way
With this article I set out to prove that cracking WEP is a relatively 'easy' process for someone determined and willing to get the hardware and software going. I still think that's true, but unlike the guy in the video below, I had several difficulties along the way. In fact, you'll notice that the last screenshot up there doesn't look like the others—it's because it's not mine. Even though the AP which I was cracking was my own and in the same room as my Alfa, the power reading on the signal was always around -30, and so the data collection was very slow, and BackTrack would consistently crash before it was complete. After about half a dozen attempts (and trying BackTrack on both my Mac and PC, as a live CD and a virtual machine), I still haven't captured enough data for aircrack to decrypt the key.

So while this process is easy in theory, your mileage may vary depending on your hardware, proximity to the AP point, and the way the planets are aligned. Oh yeah, and if you're on deadline—Murphy's Law almost guarantees it won't work if you're on deadline.
Got any experience with the WEP cracking courtesy of BackTrack? What do you have to say about it? Usb software download. Give it up in the comments.

Right, so in this guide Ill try to cover up all I can about WiFi hacking, deauthing, and cool things you can do with WiFi.
DISCLAIMER: Dont use this to hack your school's shit wifi without consent and be all cool infront of your friends blah blah blah legal use only shit like that.
NOTE: I do advise having a USB WiFi adapter, and an extra point would be to get a great one like the ALFA AWUS036NHR or AWUS051NH. Although any card would do as long as it supports monitor mode and packet injection.
When it comes to hacking WiFi points, you need to first analyze your targets and understand what you can do about each one.
The tool I will always recommend is Wifite.
Now I wont be including how to do it using any other tools, because this should work just fine. I'll leave the exploration up to you, but I will say that I always recommend to spoof your mac address using the
--mac flag to the program or macchanger . Its for your safety.
Now I wont include the guide to setting it up here, because that will go off topic.
Scanning for WiFi points to target
Simply run
wifite.py -i <wlan interface here *NOT IN MONITOR MODE*> or if you didnt understand the previous command simply use wifite.py and it will begin scanning for nearby access points and their features (Encryption method and if WPS is enabled or not).
Here are the 3 types of targets you can find:
Now within those categories, you can find a feature called WPS (Wi-Fi Protected Setup) enabled, which uses an 8 digit PIN to add devices to a WiFi network without having to input long passwords.
WEP is an old and depreceated way of protecting WiFi passwords, so if you find one, you are in luck. WEP takes substantially less time. This is easily automated in Wifite, and it even uses multiple attacks against routers to get the password. You only need around ~10 to 120 minutes to crack WEP, maybe longer. I cant say much because I have never seen any WEP protected routers were I live and never had the time to set one up and try myself.
Hacking WPA/WPA2 WiFi points
When it comes to WPA, we need to grab the handshake by deauthing clients who are connected to the router and sniffing the handshake as it goes. This is automated in Wifite, and it handles everything. Note: You may grab the handshake in a small amount of time, but cracking the hash itself will take a pure bruteforce attack or a wordlist, which takes alot of time. Only use this method if you have a really strong rig or all other options have failed.
Now comes the fun part, WPS cracking. There are 2 attacks you can do on WPS enabled routers, a WPS PIN bruteforce and a WPSPixie attack. The WPS PIN attack works online, as in all PIN guesses are actually sent to the router, while the WPSPixie attack works offline and without flooding the router with WPS PIN attempts.
Now the obvious disadvantage about the WPS PIN attack is that some routers have on-board anti-bruteforce mechanisms and will stop accepting your attempts after a few attempts. I only go this route if the WPSPixie attack fails and there is no anti-bruteforce mechanism (Wifite will tell you if detects one).
The WPSPixie attack is one of the best attacks on Wifi points I have ever seen. In most cases, you can get the WiFi password in minutes or even a few seconds. Be aware that it may take up to 30 minutes in some cases, although I have never personally seen it go beyond 10 or so minutes. NOTE: The WPSPixie attack may not work on some routers, and you will have to choose a different route. (Wifite will also notify you if the WPSPixie attack will not work.
EDIT: I forgot to mention that sometimes you will see that Wifite gets stuck at
Waiting for beacon from 'xx:xx:xx:xx' . If it gets stuck for a while at this point, press CTRL+C and move on to a different target.
That concludes the WiFi cracking part, I know I didnt include the Fake Twin AP attack, but if you people insist, ill include it. For now, Ill recommend WifiPhisher.
DoS Attacks (Deauthentication attacks) on WiFi
Sometimes you just want to be an ass and jam a certain WiFi point or even all WiFi points around you. I'm not an angel, and I have done this multiple times in public with a RaspberryPi in my backpack and a ALFA 5 dBi antennae attached to it.
Most tutorials will tell you to use
aireplay-ng , which is a great framework, but can be complicated and doesnt support Mass Jamming. Excel data analysis tool for mac. Introducing, wifijammer. The README file in the github repo provides great information about the tool and how to use it, so I wont include explanation here either. NOTE: For those tech savvy out there, if you have a RogueAP setup, this tool is perfect to jam all other access points except yours to tempt people into connecting to yours.
Change Wifi Password Mac
This ends the DoS attacks part, since its really all in one tool.
Trend micro removal tool for mac. I never tried this tool before, but alot of people have told me this works. https://stepyellow770.weebly.com/download-endnote-for-mac-usyd.html. Ni vst plugin tool for mac. This bypasses the captive portal (login screen) on most public WiFi's such as cafe shops and hotels. This tool is called cpscam.

Alright folks, that concludes this guide! Feel free to ask any questions, request any more guides, or ask me to add something to this guide!
Flood Wifi beacons (flood the list of available wifi points)
I literally just heard about this attack from /u/inksaywhat and I read about it online. Wifi beacons are basically what wifi points send out to show that they exist (their signal kind of) and it contains information about the wifi point (encryption used, name, speed, mac, etc). I never thought about this and was about to write my own tool for this but discovered that
mdk3 has the ability to flood beacons. They even say that it can crash network scanners and drivers, making it some sort of DoS attack at the same time. So to run this kind of attack, make a text file filled with random beacons (Idea: make them all cuss words, or dynamically generate them with a script or tool like crunch ) and launch the attack like this: mdk3 <mon interface> b -f file-with-names.txt .
