wpa/wpa2 wifi cracking problem bt5 r3 Please help!!

[gr33n]

Hey guys so I have been having problems trying to hack wpa/wpa2 passphrases because when I cant get a handshake no matter what I do.
Even if there are stations connected to the router and btw  I have changed my mac address by using

Code: [Select]

macchanger -A mon0I still cannot figure out why.
any tipes would be greatly apreciated.

Thanks, gr33n.

I'm assuming your using airosnort or w/e it's called on BT5, but have you even checked your wifi card to make sure that it can inject packets? Because if it can't, your fucked.

Or are you not connecting to networks period? Can you connect to a network you know the passphrase too? If not, then you need to install the drivers most likely, Backtrack is a royal pain in the arse with them drivers...

Thanks for such a quick response.
I am sure that my wifi card can inject packets because I can get the handshake using my own router but for somereason if I try it on another it just flat out doesn't work :/
I am really confussed by this as I have changed my mac address so even my own router shouldnt know its me ?
there are about 4 other routers in the area I am now but one doesnt have any stations and I cant get a handshake on any of them.

How sensitive is your adapter? does it have an antenna?
Do you receive the ACK's when doing the deauth?
Whats your distance? Walls?

my wifi chip does not have an antenna it is in a laptop.
I am sorry but I don't remember if I received ACK's
the distance to my router is about 10 meters away with 2 walls in the way.

I don't know how far away or how many walk are between me and the other routers.

If there aren't any stations associated, you won't have luck getting a handshake.

Also, if you're using you laptop's wifi adapter, there isn't much you can do, apart from trying to get closer to a window, which is what I did before buying my alfa.

Other than that, and if you have the money, I would advise you to buy an external wireless adapter (alfa cards are awesome). I have a AWUS036H with a 16dbi directional antenna, all together costed me about 60€ (around $80).

That was basically my point.
Even if you manage to deauth the target you will probably not be close enough to sniff the handshake.

I remember those days when I walked around the house with that laptop.
That was before I got a whole collection of wireless toys.

Woahh thats a lot of money just for some fun but I definently appreciate your help thanks man I might insvest in a card like that sometime would you be able to tell me where you acquired yours?
and yeah I understand that there must be stations and in all cases that I tried to get a handshake there where stations present.

Thanks for your help hahahah I probably should invest in that alfa AWUS036H wireless card if I want anything to come of my hacking adventures hahahah

Thanks for all your help

I got mine from ebay. It was a bit expensive, but nowadays you can find them cheaper, I guess.

[gr33n]

yeah they look to be around 30 $ I think I might spend an extra 10 - 20$ and buy a 20dbi antenna as well

thanks for your help guys greatly appreciated

I bet 1 5minute fapping video that there aren't any associated clients which is why he's not getting a handshake. This is a good rundown:

I'm having the same problem even with my router, I can't seem to establish a handshake no matter what.

If there aren't any stations associated, you won't have luck getting a handshake.

I have a few questions. Why there must be a station connected to the AP in order for you to establish a handshake, Also what's wrong with the laptop's wifi adapter?

[Snayler]

Why there must be a station connected to the AP in order for you to establish a handshake

Let me try to explain this: You're not establishing a handshake, you're capturing one. A successful handshake is generated when the client has the right key for the AP, and that's what you need in order to crack the WPA key. That's why you need to have a client connected to the AP, so that you can deauth (much like "kick") that client, which in turn will try to reconnect and will generate the handshake you're looking for.

Also what's wrong with the laptop's wifi adapter?

There's nothing wrong with them (apart from them not working with virtual machines, which is normal), but you have to keep in mind that they are not as powerful as, say, a Alfa adapter. Sometimes you may catch an AP with connected clients, but the AP is so far away that the card won't be able to efficiently communicate with the AP/deauth clients. That's when a USB card with RP-SMA plug + a good antenna becomes handy.

I think this is probably why the Backtrack book strongly recommends you by a Alfa wireless USB adapter. It's only about thirty dollars as already been said. I would try Newegg.
