WEP Cracking

Is PSK unbreakable?

 

[bboy]

well technically no but practically its pretty good

EVERYRTHING THAT MAN MAKES CAN BE BROKEN,sO THERE IS NOTHING IN THIS WORLD THAT cannot be hacked,(except bill gates bank account)

I even got onto a network used by apple computers(free internet by using my psp:range 30 metres)just see the settings on the psp you will know what i mean

I agree but the time element?

So how log would it take to hack a network that utilises only MAC security and that is not broadcasting its SSID?

 

[kronoSX]

How many logs depend on you,only you can prevent forest fires,(just kidding)
The time limit i think depend on(really how fast your pc thinks/and i think its also got to do with 16/32/64/128 bit..etc cracking.I said i think i dont know much

If the network is active, its SSID is being sent anyway (in its packets) and can be picked up by programs like Kismet. The client MAC address is also sent. Once these two have been picked up, an attacker can launch a deauth attack against your computer (disconnect it from the WLAN), change his wireless card's MAC address to the same as yours, and connect to the network.

So, quicker than hacking WEP!

Edit: And, as above, WEP can be hacked in 5 minutes, most of that time is capturing lots of packets. So in direct answer to your question, probably under 1-2 minutes.

will "WPA-PSK" make a network much harder to hack? my router has that option atm im only using wep 128bit

Slightly off topic (and maybe old news to some of you), but I suspect useful info for some of the people asking questions in this thread:
http://www.twit.tv/SN?p=7 - listen to episodes 10 and 11.
Transcripts and low bandwidth versions are at http://www.grc.com/SecurityNow.htm

Short answer: Yes

Take a look at the links a few pages back - WEP can be cracked by a determined cracker in 5-10 minutes!

The only way that is presently known to crack WPA-PSK is a brute force attack. Some brute force attacks first try words that are in the dictionary, so don't use an easily-guessed password. Rather use a combination of letters, numbers and special characters (%^&*)(#@! etc). Also use the longest password possible (63 characters, if your AP supports it). That'll make it practically impossible to brute force.

Thanks for the links HvRoyen, very informative

ok i guess im gonna chance to WPA-psk
