Crack WEP using BackTrack

wepcrack04

Lifehacker wrote a guide for cracking a WiFi network’s WEP password using BackTrack. BackTrack is a Linux live CD used for security testing and comes with the tools needed to break WEP. Not just any wireless card will work for this; you need one that supports packet injection. The crack works by collecting legitimate packets then replaying them several times in order to generate data. They point out that this method can be hit-or-miss, especially if there are few other users on the network, as the crack requires authenticated packets. We covered cracking WEP before, but using BackTrack should smooth out compatibility issues.

If there are few users on the network and not many IVs are being captured, you can use an injecting attack to generate more. It’s been a while since I’ve reviewed it, but it really beats sitting around for an hour.

This is so OLD I think the dinosaurs knew about it.

^^ can’t add anything to this
(so old its lame to call it a hack)

btw using plain ubuntu you’ll be “hacking” WEP networks in no time compared to backtrack. Backtrack isn’t the best O/S and trying to get YOUR hardware to work with it is a major pain in the A$$.

thanks for the old news

Very very old news! My grandma knew about it xD

like we needed another backtrack wep cracking tutorial on the net. seriously there are literally hundreds that are accurate already.

Wait, you can get the internet without wires? Like that’s total awesome! I’m telling all my buddies on Compuserve!

“but using BackTrack should smooth out compatibility issues.”

Except when BackTrack is not compatible. Like with the last 3 laptops I tried it on. Worked great on my desktop, but it’s kinda hard to wardrive with that.

@dennis could you maybe expand a little bit on *how* to do that?

Posted at 2:43 pm on Jul 2nd, 2009 by paul

Please dont tell me that people havent already heard about this? Oh and just to point out backtrack aint essential. I mean aircrack-ng runs on many linux platforms the only advantage is for windows users who wanna try linus before making the right move ;)

yep old news… If I wanted lame news I would have subscribed to Lifehacker…. oh wait, I already do!

*DOH*

This is soooo old, i was using auditor…

Atheros AR5001X is a great card when using backtrack.

Backtrack 4 beta is much improved. I couldn’t get stuff working on BT3 that works ‘out of the box’ with BT4b.

this is a brutally old guide though it still applies. just use an updated OS and you’re set. heck, slax with compat wireless and aircrack will do it almost the same.

bt3 + spoonwep = easycheese

Posted at 5:38 pm on Jul 2nd, 2009 by ThatGuy

I agree bt4 is much improved. I prefer Back Track 3 for 2 reasons.
1)Bt 3 will fit on a 1 gig flash drive
2)Bt 3 slackware based opposed to BT4 and its Ubuntu root’s (pun intended).

Been there, done that.

@dennis
It’s fucking cracking!! Learn what hackers are before you go blasting bullshit from your vocal cords (or keyboard).

@paul, just apt-get install aircrack-ng then RTFM.

@ benny_m: I kn0w what h4ck3rz are- mostly wannabe kids thinking like “oh woooow now that I’ve cracked my own insecure home WEP network I can call meself a h4ck3R!!!!

left to say: l0l

btw what does backtrack help when your hardware is not supported with the drivers provided with it, or if you need to patch them to enable packet injection? I doubt you’d prefer BT3 or BT4 over any standard good linux distro anymore. Besides all software incluuded in BT is also abailable as .rpm or .deb for *real* linux. :D

Posted at 12:27 am on Jul 3rd, 2009 by Dennis

ok – that was weird. I thought I’d travelled a few years into the past. I was all ready to play the lottery again too……

Did everyone bring their own weapons?

Posted at 1:57 am on Jul 3rd, 2009 by shibathedog

Was this some weird kind of archive injection attack?

Posted at 4:34 am on Jul 3rd, 2009 by lolz

Olá

This is so, old!

Backtrack is good enough. And RT73 is one of the best cards doing packet injection.

2003 called. They want their WEP cracking guide back

who uses wep anymore unless you abso-freaking-lootly have to… I got some cassettes we can jam out to

Word up.

We should be talking about a faster way to crack wpa then rainbow tables .. maybe use gpu power.

FAIL!

Look at you all strengthening the SEO keywords of useless news.

I love you hackaday, but BAD CALL.

Posted at 3:21 am on Jul 5th, 2009 by Dynexus

Hhsahsahha! Wow, breaking news! Holey $hit I guess hackaday is done for. One of the worst articles you have ever published

Posted at 1:35 am on Jul 6th, 2009 by Tommy

Are you kidding, did hackaday really publish this. An article showing some of the new features of backtrack 3 would have been nice, but did you really have to spoon feed kiddies this info, if they are ready for it, they will learn it on their own. There are plenty of enough resources out there.

Ok guys, i think that will do. enough of the sarcasm. I am sure that the message has been received.
Peace.
