There are two types of ways to potentially crack a password, generally referred to as offline and online. In an offline attack, an attacker has a file with data they can attempt to crack. For example, if an attacker managed to access and download a password database full of hashed passwords, they could then attempt to crack those passwords. They can guess millions of times per second, and they’re only really limited by how fast their computing hardware is. Clearly, with access to a password database offline, an attacker can attempt to crack a password much more easily.
They do this via “” — literally attempting to guess many different possibilities and hoping one will match. An online attack is much more difficult and takes much, much longer. For example, imagine an attacker were trying to gain access to your Gmail account. They could guess a few passwords and then Gmail would block them from trying any more passwords for a while. Because they don’t have access to the raw data they can attempt to match passwords against, they’re limited dramatically.
(Apple’s in this way, and that helped lead to the huge theft of nude celebrity photos.) We tend to think of Wi-Fi as being only vulnerable to the online attack. An attacker will have to guess a password and attempt to log into the WI-Fi network with it, so they certainly can’t guess millions of times per second. Unfortunately, this isn’t actually true. The Four-Way Handshake Can Be Captured. When a device connects to a WPA-PSK Wi-Fi network, something known as the “four-way handshake” is performed. Essentially, this is the negotiation where the Wi-Fi base station and a device set up their connection with each other, exchanging the passphrase and encryption information. This handshake is WPA2-PSK’s Achilles’ heel.
An attacker can use a tool like airodump-ng to monitor traffic being transmitted over the air and capture this four-way handshake. They’d then have the raw data they need to perform an offline attack, guessing possible passphrases and trying them against the four-way-handshake data until they find one that matches. If an attacker waits long enough, they’ll be able to capture this four-way handshake data when a device connects.
However, they can also perform a “deauth” attack, which we covered when we looked. The deauth attack forcibly disconnects your device from its Wi-FI network, and your device immediately reconnects, performing the four-way handshake which the attacker can capture. Image Credit: Cracking the WPA Handshake With the raw data captured, an attacker can use a tool like cowpatty or aircrack-ng along with a “dictionary file” that contains a list of many possible passwords. These files are generally used to speed up the cracking process. The command tries each possible passphrase against the WPA handshake data until it finds one that fits.
As this is an offline attack, it can be performed much more quickly than an online attack. An attacker wouldn’t have to be in the same physical area as the network while attempting to crack the passphrase. The attacker could potentially use Amazon S3 or another cloud computing service or data center, throwing hardware at the cracking process and speeding it up dramatically. As usual, all these tools are available in (formerly BackTrack Linux), a Linux distribution designed for penetration testing. They can be seen in action there. It’s tough to say how long it would take to crack a password in this way.
For, it could take years, possibly even hundreds of years or longer. If the password is “password”, it would probably take less than a single second. As hardware improves, this process will speed up. It’s clearly a good idea to use a longer password for this reason — 20 characters would take a lot longer to crack than 8. Changing the password every six months or every year could also help, but only if you suspect someone is actually spending months of computer power to crack your passphrase. You’re probably not that special, of course!
Breaking WPS With Reaver. There’s also an attack against WPS, an unbelievably vulnerable system that many routers ship with enabled by default. On some routers, disabling WPS in the interface doesn’t do anything — it stays enabled for attackers to exploit! Essentially, WPS forces devices to use an 8-digit numerical PIN system that bypasses the passphrase. This PIN is always checked in groups of two 4-digit codes, and the connecting device is informed whether the four-digit section is correct.
In other words, an attacker just has to guess the first four digits and then they can guess the second four digits separately. This is a fairly quick attack that can take place over the air. If a device with WPS didn’t work in this extremely insecure way, it would be violating the WPS specification. WPA2-PSK likely has other security vulnerabilities we haven’t discovered yet, too. So, why do we keep saying? Well, because it still is.
Enabling WPA2, disabling the older WEP and WPA1 security, and setting a reasonably long and strong WPA2 password is the best thing you can do to really protect yourself. Yes, your password can probably be cracked with some amount of effort and computing power. Your front door could be cracked with some amount of effort and physical force, too.
But, assuming you use a decent password, your Wi-Fi network will probably be okay. And, if you use a half-decent lock on your front door, you’ll probably be okay as well.
WPA2: Wi-Fi Protected Access II (WPA2) significant improvement was the Mandatory use of AES(Advanced Encryption Standard ) algorithms and CCMP(Counter Cipher Mode with Block Chaining Message Authentication Code Protocol) as a replacement for TKIP. Also Read How Fluxion works?.
Scan the network. Capture the Handshakes. Use WEB Interface. Launch a Fake API Instance(Replicating original one).
Spawns an MDK3(used to send valid and invalid packets) process, which un-authenticates all users connected to the target network, so they can be tempted to connect to the FakeAP and enter the WPA password. Fake DNS server will be launched to capture all the DNS request and to redirect them to the Host running the script.
A captive portal is launched in order to serve a page, which prompts the user to enter their WPA password. Every password is verified by the handshake which captured earlier.

Welcome back, my greenhorn hackers. When Wi-Fi was first developed in the late 1990s, Wired Equivalent Privacy was created to give wireless communications confidentiality. WEP, as it became known, proved terribly flawed and easily cracked. You can read more about that in my. As a replacement, most wireless access points now use Wi-Fi Protected Access II with a pre-shared key for wireless security, known as WPA2-PSK.
WPA2 uses a stronger encryption algorithm, AES, that's very difficult to crack—but not impossible. My also gives more information on this. The weakness in the WPA2-PSK system is that the encrypted password is shared in what is known as the 4-way handshake. When a client authenticates to the access point (AP), the client and the AP go through a 4-step process to authenticate the user to the AP. If we can grab the password at that time, we can then attempt to crack it. Image via In this tutorial from our, we'll look at using and a on the encrypted password after grabbing it in the 4-way handshake.
If you're looking for a faster way, I suggest you also check out my article on. Step 1: Put Wi-Fi Adapter in Monitor Mode with Airmon-Ng Let's start by putting our wireless adapter in monitor mode.
For this to work, we'll need to use a compatible wireless network adapter. Check out our 2017 list of Kali Linux and Backtrack compatible wireless network adapters in the link above, or you can grab. Note that airmon-ng has renamed your wlan0 adapter to mon0. Step 2: Capture Traffic with Airodump-Ng Now that our wireless adapter is in monitor mode, we have the capability to see all the wireless traffic that passes by in the air. We can grab that traffic by simply using the airodump-ng command. This command grabs all the traffic that your wireless adapter can see and displays critical information about it, including the BSSID (the MAC address of the AP), power, number of beacon frames, number of data frames, channel, speed, encryption (if any), and finally, the ESSID (what most of us refer to as the SSID). Let's do this by typing:.
airodump-ng mon0. 08:86:30:74:22:76 is the BSSID of the AP.c 6 is the channel the AP is operating on. WPAcrack is the file you want to write to. mon0 is the monitoring wireless adapter.
As you can see in the screenshot above, we're now focusing on capturing data from one AP with a ESSID of Belkin276 on channel 6. The Belkin276 is probably a default SSID, which are prime targets for wireless hacking as the users that leave the default ESSID usually don't spend much effort securing their AP.
Step 4: Aireplay-Ng Deauth In order to capture the encrypted password, we need to have the client authenticate against the AP. If they're already authenticated, we can de-authenticate them (kick them off) and their system will automatically re-authenticate, whereby we can grab their encrypted password in the process. Let's open another terminal and type:. aireplay-ng -deauth 100 -a 08:86:30:74:22:76 mon0. Notice in the top line to the far right, airodump-ng says 'WPA handshake.' This is the way it tells us we were successful in grabbing the encrypted password! That is the first step to success!
Step 6: Let's Aircrack-Ng That Password! Now that we have the encrypted password in our file WPAcrack, we can run that file against aircrack-ng using a password file of our choice. Remember that this type of attack is only as good as your password file. I'll be using the default password list included with aircrack-ng on named darkcOde. We'll now attempt to crack the password by opening another terminal and typing:. aircrack-ng WPAcrack-01.cap -w /pentest/passwords/wordlists/darkc0de. WPAcrack-01.cap is the name of the file we wrote to in the airodump-ng command.
/pentest/passwords/wordlist/darkc0de is the absolute path to your password file How Long Will It Take? This process can be relatively slow and tedious.
Depending upon the length of your password list, you could be waiting a few minutes to a few days. On my dual core 2.8 gig Intel processor, it's capable of testing a little over 500 passwords per second. That works out to about 1.8 million passwords per hour. Your results will vary.
When the password is found, it'll appear on your screen. Remember, the password file is critical. Try the default password file first and if it's not successful, advance to a larger, more complete password file such as one of these.

I get this error. Opening WPAcrack-01.cap Opening /pentest/passwords/wordlists/darkc0de open failed: No such file or directory i tried it with this time darkcode.changing the zero in darkc0de to to an o.still No such file or directory.am imagining my kali doesnt have it.i deleted backtrack5 and installed kali.so how do i get other password lists and more important how do i install it straight into the aircrack-ng directory. Been trying to find that directory but i just find the file in bin.and thats it.am still learning how files are organized in ubuntu and debian in general.
I tried this this morning. I'm not sure if it worked or not. I was originally making an attempting on cracking the WPA2, yet something a little different happened, so I just followed through with a DoS attack of which i think worked.
I'm led to believe that it worked because after the deauth went through, the saw the mac addy pop back up and re-authenticate itself onto the network. I decided to quit the WPA2 crack because I never saw the 4-way hand shack after they reconnected.
It's suppose to say 4-way handshack in the top right. Here's a screenshot.
It never appeared when they reauthenticated back onto the network. Any idea why? Hey, i came across a issue, i think i went through all of the steps here word for word and about two times it said 'WPA Handshake' and the Bssid in the top right but when i went and tried to use the darkc0de command 'aircrack-ng WPAcrack-01.cap -w /pentest/passwords/wordlists/darkc0de' it at first said specify a dictionary so i entered darc0de as darkc0de.lst and it seemed to work, but now I'm coming across this in the top right console it says there is no Valid WPA Handshake but on the left one it says it went through after authentication.
I have no clue of what the password would be or even what it would start with, So that is a no go or i would have edited one of the lists, if it was just a simple word file or such, and only had the passwords with the first letter in it. I Suppose that would drastically reduce it.
Or perhaps i could break up the file into smaller ones and test them while i am sleeping. Also about the background i myself don't have internet at my house and the RAM on my computer is rather low, i don't think i should try anything else as to not Corrupt or interfere with the speed or stability of the Cracking Process. Also in your 'Reaver' Link would having BTr3 Already have all of these already?

I got the command working to where it would write the WEP file, but after i set everything up and followed the guide and went to sleep, after about 9 hours and 20 minutes i came and checked to see that no one had connected to the network i was monitoring, and that when i tried to Crack it i got no Data Packets but around 494574 Normal Packets? And it wouldn't attempt, so i decided to go and try again but then i see that i got a Handshake From a different Network which i was not even monitoring or using the Bssid of the network, even the Bssid's of the two network are different and I'm not even sure how the Handshake took place, as the one i was trying to crack was called 'Blue' Bssid: 00:0C:41:F6:A0:0E And it is a WEP The other is 'Brighton Network' Bssid: E0:91:F5:A3:ED:3E and is WPA2 which is where i got the handshake from and now i have no idea what to do. Also im unsure if my computer isn't picking up people connecting or registering any Handshakes, as i stated above it came in randomly when i was monitoring a different network and i can't use the handshake as it was not monitored at the time and wasn't written into the WEP 'Blue' File.
It seems everytime i try to do this it fails WEP or Not. Edit: 11:52 AM Okay so i went ahead and followed the WPA Cracking guide, again, and this time i got the handshake almost immediatly (Given that i am now trying the WPA on the 'Brighton-Network') And am just trying the Cracks now, Would editing a large 14GB Password file cause it to not be ran? Its not a normal.txt file so I'm unsure, or could i just change it into a txt file and be fine? I've tried opening it with Notepad, and Notepad But it says the file is too large to open in them. (The file is actually realuniq.lst) Reply. So hack a wifi.
Ok lets say i want to hack a WiFi or obtain internet access in a very conventional way such as. Purchasing a cable modem from retail and registering it under a cold real address(cold means no one lives at the address nor doesn't have services with the cable company or the ISP i am asking services from). Registering internet with many cable providers doesn't require a tech to be sent out and do the installation, it can be activated over the phone and without a truck roll, use of social engineering techniques are required to accomplish that task. So now the modem is registered at an address that is 20km away from my house where the modem is actually being used. Would that be traceable as well? Would they go by the billing address where services are bound to or they go by IP of the WAN and therefore come over where the modem is physically located? In that case, the modem IP would still be my house location?
How does it work in terms of ISP companies head ends that feeds each serviceable address with RF cable? Jacob: First, I want you to be careful until you know more.
Second, there are problems with your strategy. The first is that the cable company can trace the location of all Internet services (not so with TV services).
Crack Wpa2 With Wifi Slax
The second problem is that your payment could be traced unless all payments are in cash. The best way to use wifi anonymously is to hack someone's password who is good distance away (say.5-2 miles). Then use there wifi with a high gain directional antenna. I have worked with law enforcement agencies and even when they know the wifi is hacked, they focus their investigation to surrounded houses/neighborhood. Hi, N00B here.
Been trying to follow the steps but I get shot down at first crack. When I enter iwconfig (to find my wireless card) I get lo no wireless extensions. Eth1 no wireless extensions.

PID Name 954 dhclient3 2715 dhclient 2733 dhclient Let me know if you can guys? Is this something I may need to do? I have BT v3 iso both the 32 and 64 versions. Tried running the 64 version off of a usb with a little over 7 gb space.
Booted off the usb and ran in text mode. Entered startx to get to gui. Then tried iwconfig and it couldn't find anything. I have an external wireless reciever.
I am pretty sure it is aircrack compatible. It is a NETGEAR WNDA3100 not sure if it is v1 or v2 but I believe both are compatible. Do I need to install BT to my machine instead using a VM? Also I've learned something very important. If you've tried the process more than once you will need to ensure that monitor mode is disabled before you start it again or you will get unsuccessful processes such as the above. Simply type airmon-ng stop mon0 then airmon-ng stop wlan0 to take your wifi out of monitor mode and then restart the process.
After putting your card in monitor mode and you're finished doing whatever you're doing always take the card out of monitor mode. Trust me, I've been around the world in the past week learning this thing as a newbie and if you're following a tut such as this then READING IS BOTH FUNDAMENTAL AND ESSENTIAL to understanding the process.
You may also try switching your mon0 channel.

I have to say, this is somewhat better than reader because most new routers blocked the wps hole. I have a problem and some questions master OTW. They go as follow: I'm very new to Linux and backtrack. Like a slutty virgin, this is my first time. I followed all the instructions and everything is fine but the wordslist doesn't have the password.
I have routers around me I know uses numbers as password. Please, I need to know the command to use if I saved a wordslist on the desktop what will I enter in the command exactly.
Also, how do I create a wordslist of numbers or where can I get a number list? What file type does the wordslist need to be? Is there a number list and where can I get? Thanks a lot. I just need wifi for peaceful browsing. I have dled both the 32 and 64 iso for backtrack 5.
Used unetbootin to put the 64 iso on usb and booting from that. I'd rather use the 32 version on my laptop but I think it may be too old because I can't get it to boot anything from the usb(I have tried 32 and 64 version and neither work). It just goes straight to windows xp.
On my desktop I don't have a wireless card I have a usb plug in wireless receiver. Netgear wireless N dual band. I am guessing this is a problem since when I boot using the usb and get backtrack up. I type in startx and get the gui. I try entering in iwconfig and it finds nothing. Is there any way around this?
Or am I hosed? Bee Kay: When you are in BT, try removing the usb wireless adapter and then inserting it. If BT has a driver for your card, it will automount the device and driver, similar to Windows PnP. If that doesn't work, there may not be a driver for the wireless adapter in BT. You can then either find a driver and install it or buy a new wireless adapter that has a driver in BT. Buying another wireless card might be your best bet as few wireless card are compatible with aircrack-ng.
Before you buy, check if it is on the compatible list. I recommend the Alfa cards. They are cheap and fully compatible with BT and aircarck-ng. I tried what you suggested and it didn't seem to work. I am taking your advice and looking into alfa cards and found this site. It has a list of the best cards for BT5 and I was wondering if I should go with the first or second card on the list.
Both Alfa cards. The Alfa AWUS036H is the top rated but then they go on to say it is commonly counterfeited. Where is a legit site where I can grab one?
Tried contacting Alfa and haven't had any replies. Also this card doesn't broadcast in N. Would that be a problem if I tried using it for finding a network broadcast in N?

I'm new to all this.
In fact I'm pretty new to Linux. Everything has worked for me so far but when I get to the deauth command the message I get is as follows: 'Waiting for beacon frame (BSSID: XX:XX:XX:XX:XX:XX) on channel -1' followed. 'Couldn't determine current channel for mon0, you should either force the operation with -ignore-negative-one or apply a kernel patch' followed.
'Please specify an ESSID (-e)' It seems to me that the BSSID is being associated with channel 1 although I specified channel 8 in the previous airodump step. In fact, the airodump terminal even displays 'fixed channel mon0 -1'. Should the deauth command have also included the channel? What am I missing? By the way the more I learn the more I begin to realize things I had no clue about before. Like I said, I'm a noob to Linux but very excited to expand my knowledge base. That being said, I'm seeing from most of the screenshots here that most are using Kali for for this.

Does your WiFi adapter packet inject? #Observations: Airmon-ng: (No channel specified in command) airmon-ng start wlan0 8 Aireplay.?:-) aireplay-ng -0 10 -a xx:xx:xx:xx:xx:xx -c xx:xx:xx:xx:xx:xx wlan0 -a AP first set of #s -c (client=Target) second set of #s -0 Deauth Attack 10 Amount of deauths to send. Side Note: I would disagree on Ubuntu as a Pen-test learning platform. Don't get me wrong, its a great OS. If you are on the Pen-test path you need a Pen-test OS Like Backtrack. I started on UNIX back in 90's went on to learn Linux and pen-testing with Backtrack 1 in the 2ks.
You can pimp BT to act like a Ubuntu by adding the packages you want BTW. (just a thought.) If I were you, I would grab a Live CD of Kali since BT has evolved into Kali. Use it to play around with, make a persistent USB of it (32-64 GB). Treat it like a installed version since it will remember everything you do on next boot up.
Good Luck;-) -This should solve most issues as far as making connection.- Reference: Why does deauthentication not work? There can be several reasons and one or more can affect you: You are physically too far away from the client(s). You need enough transmit power for the packets to reach and be heard by the clients. If you do a full packet capture, each packet sent to the client should result in an 'ack' packet back. This means the client heard the packet. If there is no 'ack' then likely it did not receive the packet.
Wireless cards work in particular modes such b, g, n and so on. If your card is in a different mode then the client card there is good chance that the client will not be able to correctly receive your transmission. See the previous item for confirming the client received the packet.
Some clients ignore broadcast deauthentications. If this is the case, you will need to send a deauthentication directed at the particular client. Clients may reconnect too fast for you to see that they had been disconnected. If you do a full packet capture, you will be able to look for the reassociation packets in the capture to confirm deauthentication worked. Thank you masters OTW and Cyberhitchhiker.
That gives me some direction. Looks like I'll delving into Backtrack sooner rather than later. I've never been known for my patience although I'm sure it will be tested as I move forward. Kali looks like a sexy little distro and I'll go ahead and order the disks.
Can you direct me where to do that? I only see a download link on.
In the meantime I'll download the iso as I would like to get started. I'm familiar with creating a bootable flashdrive with the iso, having done so with Ubuntu. Will I be able to run the OS from that alone (obviously without doing an install) or is there more to it than that? I'm sure I will eventually do an install, unless there is more security in running it from the flashdrive, I don't know. Your thoughts? And as always. I'm still trying to find where I can order the Kali disks.
Also I'm trying to determine the usability of the aircard on my Dell Inspiron 17R N7110 17.3 Laptop (Intel Core i7-2630QM Quad-Core Processor). The hardware specs of which indicate: Dell Wireless 1702 802.11b/g/n Device Type: Network adapters Manufacturer: Atheros Communications Inc. Location: PCI bus 1, device 0, function 0 I'm trying to find a comprehensive list to see if this will work or if I'll need to purchase an external wireless adapter. Your continued patience is appreciated. OTW: Great tutorial - very easy to follow through! I've skimmed through the above comments so apologies in advance if this has already been asked: I was wondering about the syntax of implementing a password dictionary as above - is there a method through which aircrack can combine multiple words within a dictionary together and test each of those as a separate password? Also, is there a specific syntax available for when you know the password is a single word, and then a string of numbers?
Say, implementing dictionaryone:dictionarytwo, where one is the words and two is the numbers? Thanks, OV Reply.
I have cracked the password, it is not connecting to my cell phone.First it scans then try to use remembered password and then say connecting.Just after authenticating it again start scanning and it start repeating the process again. After two or three try, the wi-fi network disappears. I see you said MAC or IP Filtering to Secret(a Member).
How to crack the MAC or Ip filtering. I researched on internet and found that my HTC Wildfire requires network certificate(.p12). Or is there any other term, Please tell me i cant wait to crack down my network fully Reply. Hi OTW, Ran into a problem whilst trying out to hack WPA password for a wifi, when I issue the aireplay-ng -deauth 100 -a 92:4E:2B:2D:FA:DB mon0, I get the following error: waiting for beacon frame (BSSID: 92:4E:2B:2D:FA:DB) on channel -1 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 ESSIDE (-e). When I use force using the ignore negative one option, it just goes on and on, without deauthenticating and then finally stops.
What am I doing wrong please?
. Start. Prev. 1. Introduction The world has changed since was written in 2008.
While there are some wireless networks still using WEP, there has been a mass migration to WPA2-AES wireless security. A key reason for this move is 802.11n, which requires WPA2/AES security enabled in order to access link rates over 54 Mbps.
Cracking techniques have changed too. While most techniques still use some form of dictionary-based exploits, the power of the cloud has also been brought to bear on password cracking.
In fact, prompted Tim to ask me to revisit the original article and update it to include the new methods Dan described. So here I am. Brandon's article provides a good WPA primer, so I won't repeat that here. The key things that you need to know are:. The information we need to capture is contained in transmissions between AP and STA (client) known as the 'four-way handshake'. The techniques used to recover the passphrase are primarily forms of So, let's just jump in after a few 'need to knows'.
Warning and Disclaimer. Accessing or attempting to access a network other than your own (or have permissions to use) is illegal. SmallNetBuilder, Pudai LLC, and I are not responsible in any way for damages resulting from the use or misuse of information in this article. Note: The techniques described in this article can be used on networks secured by WPA-PSK or WPA2-PSK. References to 'WPA' may be read 'WPA/WPA2'. Setup To crack WPA-PSK, we'll use the venerable Live-CD SLAX distro.
It's free to download, but please consider donating, since this really is the Swiss Army knife of network security. As you can see from my system specs in Table 1, it doesn't take much computing power to run WPA cracks. Attacking System Specs Model Dell Latitude D630 laptop Processor Intel Core2Duo T7100 (1.80 GHz) Wireless Adapter Intel WiFi Link 5300 AGN OS BackTrack 5 R3 KDE 32-bit (build ) Target Wireless Access Point NETGEAR WNDR4500 (SSID: 9105GirardCh6) Target AP MAC 20:4E:7F:0C:05:C3 Target AP Client MAC 00:19:88:22:96:BC Table 1: Attacking System Specs. BackTrack 5 R3 is the current version over at so that's what we'll be using. First, the BackTrack ISO.
I decided to boot BackTrack as a USB thumb drive with 4 GB of persistence. For this I used a 16 GB USB thumbdrive and. Recon with Kismet Open up, the venerable wireless surveillance tool ( Backtrack Information Gathering Wireless Analysis WLAN Analysis Kismet).
Upon opening Kismet you will need to select your wireless interface, which you can grab by typing 'iwconfig' in a terminal. Kismet is a great surveillance tool, but that is only one of its many talents. It captures raw packets while operating, which we can use later to attack weak PSKs, having captured a client connection while listening. It also has some interesting alerts built in, to warn you of potential evil-doers within wireless range. To top it off, Kismet is completely passive and therefore undetectable. In of our original WEP cracking series, Humphrey Cheung wrote a great introduction to recon with Kismet.
Recon for WEP cracking and WPA cracking is very similar, so I won't repeat all that information here. Instead, I'll just point out a few settings and options that I find useful as well as explain a bit of the interface. I would add, however, that Kismet is very versatile and customizable with great context-sensitive help menus. In the main network list, access points are color coded by encryption method, which we also see indicated in the 'C' column. Green (N) indicates no encryption method, while Red (W) indicates WEP encryption.
Yellow (O) indicates other, usually meaning WPA / WPA2. You can see that highlighted an SSID provides more details about that specific AP. Figure 1: Kismet Information Screen The other interesting parts of the Network List display for our purposes include the T, Ch and the Pkts columns. The Ch column, as one might expect, is the channel of the access point. We'll need this information later if we employ an active attack.
The Pkts column lists the number of packets captured by Kismet for a particular access point. While not completely relevant, it gives us a decent ball-park measurement of both network load and proximity. Higher network load usually translates to higher number of connected clients, which increases the chance that we could capture a client association passively.
Kismet defaults to autofit mode, where you can sort the networks and bring up the Network Details page by highlighting an AP and hitting enter. The Network Details page list all sorts of interesting information about the network most notably the WPA encryption scheme, BSSID and number of clients associated with the access point. Pressing c while in the Network Details view will bring up the connected Clients List. The Client List shows all the nodes with traffic associated with the access point. This is one reason it's nearly useless to set MAC filters at a router. In seconds, Kismet can give an observer your client MACs, which can then be easily configured to the attacker's network adapter.
The client list can also be shown on the main page by selecting 'Client Details' under View as shown in Figure 1 above. Passive Attack In a passive attack, all we need to do is listen on a specific channel and wait for a client to authenticate. Kismet is the weapon of choice here, although airodump-ng works too. Kismet gives you much more control and information than airodump-ng, but unfortunately doesn't provide notification to alert you of a successful WPA-PSK association four-way handshake.
Airodump-ng does, but gives you less dynamic control of the capture card's behavior and very little information (compared to Kismet). General Kismet recon and capture steps for a passive WPA-PSK attack are:. Start Kismet. Sort the networks (Ex: by channel, press 's' then 'c'). Lock channel hopping onto the channel of interest (highlight the target AP and press 'L').
Wait until a client connects to capture the association.
1) Does This method actually work?? Ans: Yes, it works, but not on all kinds of networks and routers. As i mentioned in the above article using jumpstart you can hack only wifi routers secured with wpa/wpa2 - wps enabled 2) Jumpstart it shows Wireless configuration failed!what could be the reason for it not to be successful? Ans: Same answer as above, because it is not programmed to hack advanced routers.
To put it into simple words, router is much more stronger than the attack 3) Hacking With JumpStart Failed, how should i hack this particular network now?? 4) Networks Found in Wifi Tab but nothing in WPS Tab, what should i do not? Ans: This is neither your fault or Dumpper's or the system's fault. This happened because there are no WPS enabled networks near you, that's it. It clearly means Dumpper can not hack the networks that are not WPS Disabled. Kool and the gang spirit of the boogie rarest. So you need to go for another method of wifi hacking, which means you need to work a little on Kali Linux to hack, even though its not as easy as Dumpper.
In case Jumpstart Failed to hack the router try the following (Hacking With Linux).
