So by now you must have something like XX:XX:XX:XX:XX:XX, which is the BSSID of your target network. Copy the BSSID of the network you want to hack. None of them has WPS enabled, just saying.īSSID of the network – Now irrespective of what you used, you should have a BSSID column in the result that you get. You’ll have to assume they have WPS, and then move to next steps. So, where is this taking us? The answer is, there are flaws in this technology that can be used against it. Basically, 8 digits and 10 possibilities per digit (0-9) make it 10^8 (interpret ^ as raised to the power of)seconds if we assume one key per second.

Now in WPS, there is a delay because we have to wait for APs response, and we may only try a few keys per second (practically the best I’ve seen on my PC is 1 key per 2 sec). However, we can try thousands of keys per second, which make it a tad bit easier. This make the task a billion billion times tougher. Under normal bruteforcing of WPA passwords, you have to consider the fact that there may be number, alphabets, and sometimes symbols (and more than 8 letters).

Now a pin has 8 digits, and only contains numbers, so its a possible target for bruteforece. So basically, the client sends 8 digit pins to the access point, which verifies it and then allows the client to connect. Now while most of the things are the same as in WPA, there is a new concept of using pins for authentication. Users have been urged to turn off the WPS feature, although this may not be possible on some router models.

The flaw allows a remote attacker to recover the WPS PIN in a few hours with a brute-force attack and, with the WPS PIN, the network’s WPA/WPA2 pre-shared key. A major security flaw was revealed in December 2011 that affects wireless routers with the WPS feature, which most recent models have enabled by default. Prior to the standard, several competing solutions were developed by different vendors to address the same need. It still might take hours, but it is much better than the previous scenario in which months of brute-forcing would yield no result.Ĭreated by the Wi-Fi Alliance and introduced in 2006, the goal of the protocol is to allow home users who know little of wireless security and may be intimidated by the available security options to set up Wi-Fi Protected Access, as well as making it easy to add new devices to an existing network without entering long passphrases. However, it had a hole, which is now well known, and tools like reaver can exploit it in a single line statement. Now basically it was meant to make WPA even tougher to crack, and much easier to configure (push a button on router and device connects). With this in mind, a new security measure was introduced to compliment WPA. But it was not over yet, as the new WPA technology was not at all easy for the users to configure. And finally the security folks were at peace. Rainbow tables are known to speed things up, by completing a part of the guessing job beforehand, but the output rainbow table that needs to be downloaded from the net is disastrously large (can be 100s of GBs sometimes).

An exhaustive bruteforce including all the alphabets (uppercase lowercase) and numbers, may take years, depending on password length. A dictionary attack may take days, and still might not succeed.

Now hacking WPA/WPA2 is a very tedious job in most cases. When it was known that a WEP network could be hacked by any kid with a laptop and a network connection (using easy peasy tutorials like those on our blog), the security guys did succeed in making a much more robust security measure WPA/WPA2.
