How To Crack WPA / WPA2. Introduction. There is a new version of this article here. Previously, we showed you how to secure your wireless with industrial strength RADIUS authentication via WPA- Enterprise.
It turns out that there's a little back- story there. So, in traditional Tarentino fashion, now that we've already seen the ending, let's back up to the beginning: cracking WPA- PSK. Wi- Fi Protected Access (WPA) was created to solve the gaping security flaws that plagued WEP. Perhaps the most predominant flaw in WEP is that the key is not hashed, but concatenated to the IV, allowing completely passive compromise of the network. With WEP, you can literally sit in your car listening for packets on a network. Once you have captured enough of them, you can extract the key and connect to the network.
The objective is to capture the WPA/WPA2 authentication handshake and then use aircrack-ng to crack the pre-shared key. This can be done either actively or passively. WPA2-PSK may not be as safe as you think. There are a few attacks against WAP2-PSK. One of the most common attacks is against WPA2 is exploiting a weak passphrase.
WPA solves this problem by rotating the key on a per- packet basis, which renders the above method useless. However, nothing is perfectly secure, and WPA- PSK is particularly vulnerable during client association, during which the hashed network key is exchanged and validated in a "four- way handshake". The Wi- Fi Alliance, creators of WPA, were aware of this vulnerability and took precautions accordingly. Instead of concatenating the key in the IV (the weakness of WEP), WPA hashes they key using the wireless access point's SSID as a salt.
The benefits of this are two- fold. First, this prevents the statistical key grabbing techniques that broke WEP by transmitting the key as a hash (cyphertext). It also makes hash precomputation via a technique similar to Rainbow Tables more difficult because the SSID is used as a salt for the hash. WPA- PSK even imposes a eight character minimum on PSK passphrases, making bruteforce attacks less feasible. So, like virtually all security modalities, the weakness comes down to the passphrase.

WPA- PSK is particularly susceptible to dictionary attacks against weak passphrases. In this How To, we'll show you how to crack weak WPA- PSK implementations and give you some tips for setting up a secure WPA- PSK AP for your SOHO. Note: The techniques described in this article can be used on networks secured by WPA- PSK or WPA2- PSK. References to "WPA" may be read "WPA/WPA2".
