Re: Cracking WEP and WPA keys

I wasn't comparing anything, I was asking how realistic it is to crack
the WPA key in 10 minutes.

I'm asking as I was lead to believe that WEP could be cracked in
minutes with brute force attacks but have found from experience that
that is wrong, I am therefore now doubting the people who claim how
easily WPA can be cracked

Hi
I've just been on a wireless security course where there was a lot of talk
about WEP keys being poor security and easily crackable. I got home and
decided to put it to practice and use aircrack against my own WEP key.

After around 4 hours I got bored ...

All the examples I've seen seem to suggest that cracking should take minutes
not hours and all keys should be crackable. What experiences do other
testers have? Have I done something wrong? I abandoned the full attack after
5 hours as it was running with the default fudge factor of 2 so would
probably not have managed to crack the key.

I've also seen a video on the Remote Exploit site showing a WPA key cracked
in 10 minutes using cowpatty and a dictionary attack. How realistic is this?

I am not very good at this, since I do not own or care for wireless, but

*do* take in mind that you're comparing a complete brute-force with a
dictionary attack. It's not surprising that the dictionary attack is
much faster, even against a better algorithm.
