ok well i already knew all about the net user cmd commands and all that. and i also know that school computers have security that can be kinda a buzz kill. but my school is installing a wireless network over the summer break. and i was wondering if i could some how use that to bypass the security. not that there really is a use for it, but i just like to learn and ask questions.
i suggest u to first learn Wireless Network Security. After that use wireless Ignation software. hope u will get the desired.
No, Aircrack-ng or Aircrack Win32. You can crack wireless and it supports wireless packet injection with some wireless cards and you get it for free with linux, the windows one is also for free and if you want I will see what I can do and put it on my website for you to download if you have windows. Cain & Abel work well but you will have to buy a Airpcap usb wireless dongle for it to work. Cain & Abel uses Korek attack that was designed by Korek (A very good hacker) and if you need to crack WPA you can use the aireplay feature with aircrack-ng (Linux only) to send a Deauthentication attack and the capture the handshakes of the users as they get authenticated all over again. Take the hash and get a good wordlist to crack it using aircrack or cain & Abel.
