wireless networks

[pyte]

hi Residents,

i live in a city where wireless networks dominate the air
one problem though,i still pay for them!
Ive tried my best to get around them but the furthest I've got is to get ip addresses open ports and bloating my hard drive with all kinds of wap/ wep cracking tools.
anyone with a suggestion on how to successfully crack any of them?
help here will be highly appreciated

Use aircrack-ng. Download the backtrack linux OS and search for aircrack  backtrack or just type wep cracking backtrack. there is bunch of tutorials on (for example: youtube)

Best tutorials are in aircrack-ng's website, IMO.

just got aircrack-ng-1.1 for my windows pc.
is it a match for my task(cracking WPA /WEP) ?

No. Use linux.

if you find open ones, but still require you to pay for them, look into icmp tunnels. its what i use. hack-a-day has a good article on bypass captive portals.

lol wifi cracking on windows lol... The only thing you can use windows for wifi hacking is cracking a WPA handshake with a program such as Elcomsoft Wireless Security Auditor.

WEP (says backtrack 4, however it can be used with other versions, such as backtrack 5 R3)

WPA

Download Backtrack here:
http://www.backtrack-linux.org/

It's a live OS and most wifi cards (except Broadcom) are supported with the aircrack suite.

So depending on either WPA or WEP follow one of those guides (WEP is easier and faster)

Also a little special bonus is if the router you're trying to connect to has WPS enabled, you can use reaver to attack the WPS pin (7 digit number) as well as does a "smart" bruteforce on it.

As others said, you don't need to install anything to your hdd. Just download Backtrack and boot from Live CD or USB or install only aircrack-ng and crunch.

After booting Backtrack; open terminal and start monitoring
$ airmon-ng start wlan0
$ airodump-ng -w file -a -o cap mon0

and wait until you collect wpa handshake or enough wep ivs. you need a wordlist to crack wpa password, you can use crunch in this case. to crack with crunch;
$ crunch 8 8 | aircrack-ng -w - -b <<macaddress>> file-01.cap

for advanced crunch options see $ man crunch. these 3 steps are enough to crack wep and wpa wifi but advanced options in crunch or good wordlist will decrease cracking time.

or long story is social engineering. be nice to your neighborhoods and sent them gift on special days, talk them, help them and introduce yourself "computer geek", believe me, they will call you when bad things happen to their computer then you can learn wireless key from their pc. Most users use automatic connection which stores password as plain-text.
