WEP Cracking (As demonstrated by the FBI)

[primary0]

WEP cracking usually takes hours. Lots of hours, depending on the amount of traffic on the access point. A few months ago, two FBI agents demonstrated how they were able to crack a WEP enabled access point within a couple of minutes. 3 minutes to be exact. This is unbelievable when compared to, say 3 days of work. Here is how they did it, and how you can do it. You may need to know your way with each and every of these tools to get this done. You can ask Google for that. Anyway, if you are familiar with them, just do as follows :

1. Run Kismet to find your target network. Get the SSID and the channel.
2. Run Airodump and start capturing data.
3. With Aireplay, start replaying a packet on the target network. (You can find a 'good packet' by looking at the BSSID MAC on Kismet and comparing it to the captured packet's BSSID MAC).
4. Watch as Airodump goes crazy with new IVs. Thanks to Aireplay.
5. Stop Airodump when you have about 1,000 IVs.
6. Run Aircrack on the captured file.
7. You should see the WEP key infront of you now.


The software runs on Linux . I do not know any Windows alternatives. And finally, I think you should always use a combination of 2 or more security features.

This is not exactly breaking news anymore... And it works quite well.

allright i'm using aircrack, and i got the IV's i need, and the read me says to drag and drop the file in aircrack but then what???

[JoeTampa]

Well, there's no drag-n-drop - not sure where you're getting that from.

Run aircrack, it will give you it's command line options. Run it and supply that cap file and you should be able to crack the key.

the aircrack documentation http://www.cr0.net:8040/code/network/aircrack/
it came with the program, and i can't write any commands, because when I press Enter, the window exits, so I opened aommand prompt and opened aircrack through there and i can actually type in commands but then what

[JoeTampa]

Ah. Windows. Sorry, can't help you there. I suggest installing Auditor or Whax and using the Linux version.

how would i do it in linux? do you have any idea?cuz i never used linux before

I linked to a rather good tutorial in your other thread about WEP cracking. It has references and information as to what OS's and applications to use.
