How to hack a wep key with backtrack 4




















Run airodump-ng again airodump-ng —c 11 ath1 and then try to perform the fake authentication again. If you are connecting to an AP that is a bit picky, then you have some options to tweak the aireplay-ng behaviour :. From this point forward, you should be able to associate with the AP. The number of Data packets is most likely still very low and does not go up as fast as we want it to. So we need to grab an ARP packet and inject it. It might take a couple of minutes before an ARP is seen.

If that does not generate the required ARP packet s , which should set off the ARP injection, then try to deauthenticate the existing clients. If you have a second client MAC address, you can set your own MAC address to one of the clients and try to deauth the other client….

If this works, the valid client will be disconnected. When the client connects again in most cases, this happens automatically , and after max. You can already try to break the key using the ivs file that is being generated.

As long as the key is not found, and the number of packets keeps growing, the crack process will automatically reread the file and attempt to crack the key. By the time I wrote the last 2 lines of text, I had already captured IVs, which appears to be sufficient to crack the key in one shot.

So if your coverage is good, signal is strong, and the injection works well, it may go very fast. If you would not have had enough IVs, the aircrack-ng process would just sit and wait until the file has grown bigger and would then attempt to crack the key again. If the packets all of a sudden stop increasing, then stop the injection process, start it again, re-associate, perhaps deauthenticate an existing client and it should continue to grow.

The key is 26 characters, so if we assume that the key is in hex, we are dealing with bit WEP. This mode is also called WEP I guess it makes the wireless network a bit safer, but a whole lot more useless as well. So assuming that there is no MAC filtering, or you have managed to get a valid MAC address of a client earlier, or by bruteforcing mac addresses : , then this is what you can do if there are no active clients connected to the network at the time of the audit :.

The first 3 steps are similar to scenario 1. Wait until you are asked whether you want to use a packet that was captured. Ok, now you can use the. If you are using a fake MAC, then use this fake mac in the commandk.

In most cases, this attack works well. However, if you have not been able to successfully get a. This process can take multiple minutes. Follow the same steps that were used when we created a. Verify that the number of Data packets increases fast, wait a couple of minutes and start cracking.

Well, aireplay-ng —fakeauth will not just work… It will detect that Open System is cannot be used, and will then attempt to get the shared key. In fact, it needs to see a client successfully authenticate to the AP before it will be able to grab the SKA and use it. As long as a client has not associated, the AUTH column in airodump-ng will stay empty. From that point forward, you can use the Shared Key to do fake auth. Seriously—Google it. This ain't what you'd call "news. Here's how it goes.

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:. It's right there on the taskbar in the lower left corner, second button to the right. Now, the commands. 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, To see a list of wireless networks around you. 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.

I had to do this once or twice to find the network I was looking for. Once you've got it, highlight the BSSID and copy it to your clipboard for reuse in the upcoming commands. Now we're going to watch what's going on with that network you chose and capture that information to a file. Enter anything descriptive for file name. Grieve Logger V4.
