WPA encryption cracked in one minute - 28-August-2009, 10:44

The second generation of Wi-Fi security systems has now been broken as badly as its notoriously insecure predecessor: Japanese researchers say they can crack WPA (Wi-Fi Protected Access), the successor to the old-school WEP, inside of a minute's time spent eavesdropping on a wireless network.

Details on the mechanics of the attack are set to be announced next month at a computer conference, but it's tentatively described as taking to "a new level" the previous method by which WPA had been roughly compromised, adapting previously theoretical holes in the WPA system and turning them into practical attack techniques.

The previous method of attacking WPA devices took up to 15 minutes to be successful, and didn't always work. The new method is said to work on far more devices and, obviously, much more quickly. However, as with the old attack, the new one only works on WPA devices that use the TKIP (Temporal Key Integrity Protocol) algorithm, which is a setting in your router and device setup.

WPA devices that use the newer AES (Advanced Encryption Standard) algorithm, plus devices that use WPA2 -- the third generation of wireless security standards -- are still safe for now.

However, this does mean that it won't be long before this attack technique trickles out into software that malicious hackers can use to invade WPA networks. With access to your wireless network, a hacker can potentially eavesdrop on any traffic sent, access shared folders on computers attached to the network, and of course send and receive data (like illegal file sharing or even child pornography) which could then be blamed on you.

To protect yourself, upgrade the security settings on your devices to WPA2 if they all support the standard. Alternately, you can upgrade any WPA device from TKIP security to AES. Check in your router administration console and on your computer for and where how to do this.

Interesting. As well as upgrading to wpa2 I now run a 5 ghz wireless network. The shortage of 5 ghz equipment + wpa2 would have made it pretty secure?

You can just do this using backtrack software which as an open source linux distro aimed at network security enthusiasts . You just need the right type of network card and you are able to open secured networks wep and wpa in about two minutes.

Intresting, i've got a N-router myself, but not a compatible NIC. I never thought about it from the security point of view, but doing what you did plus the addition of a Access-list is probably the most secure way today.

its works . tried and tested . You just need a compatable network card which supports packet injection . Backtrack software is free to download . So before mocking why dont you just try it !!!!!!!!!!!!!!!!!!!!!!!!!

i know backtrack, and i don't need it, i'm able to build my own system. i'm not a f**king scriptkiddy.

paket injection is only used for attacking a WEP network.
for WPA or WPA2 only need the 4way handshake and this you get without any injection. and then you can start a bruteforce or wordlist attack.
you can do that in 2 minutes if the WPA pass is "12345678"

i do this stuff since many years.
you know the beginnings of paket injection? when you have needed two prism2 networkcards on the same time to do that?
i do.

so go to your schoolyard and tell your playmates that you can hack WPA in 2 minutes, but not here.
