Wi-Fi Protected Setup or WPS is a new method to connect wireless devices to the access points without physically entering the password. It was created by the Wi-Fi Alliance in 2006 to make it easy for the people who knew less about wireless network to connect devices to their existing network without using the long passwords.

Today we will learn WPS cracking using reaver.
What is WPS ?
WPS stands for Wi-Fi Protected Setup and was designed to make setting a secure AP simpler for the average homeowner. First introduced in 2006, by 2011 it was discovered that it had a serious design flaw. The WPS PIN could be brute-forced rather simply using tools like Reaver.
What is Reaver ?
Reaver is a free, open-source WPS cracking tool which exploits a security hole in wireless routers and can crack WPS-Enabled router's current password with relative ease. It comes pre-installed in Kali Linux and can be installed on other Linux distros via source code. Reaver performs a brute force attack against an access point's WiFi Protected Setup pin number. Once the WPS pin is found, the WPA PSK can be recovered

Description:
Reaver-wps targets the external registrar functionality mandated by the WiFi Protected Setup specification. Access points will provide authenticated registrars with their current wireless configuration (including the WPA PSK), and also accept a new configuration from the registrar.
In order to authenticate as a registrar, the registrar must prove its knowledge of the AP's 8-digit pin number. Registrars may authenticate themselves to an AP at any time without any user interaction. Because the WPS protocol is conducted over EAP, the registrar need only be associated with the AP and does not need any prior knowledge of the wireless encryption or configuration.
Reaver-wps performs a brute force attack against the AP, attempting every possible combination in order to guess the AP's 8 digit pin number. Since the pin numbers are all numeric, there are 10^8 (100,000,000-1 = 99,999,999) possible values for any given pin number, considering 00,000,000 is not the key. However, because the last digit of the pin is a checksum value which can be calculated based on the previous 7 digits, that key space is reduced to 10^7 (10,000,000-1 = 9,999,999) possible values, again as checksum of first 6 zero's will be zero, we remove 0,000,000 to be brute-forced.
The key space is reduced even further due to the fact that the WPS authentication protocol cuts the pin in half and validates each half individually. That means that there are (10^4 )-1 i.e 9,999 possible values for the first half of the pin and (10^3)-1 i.e 999 possible values for the second half of the pin, with the last digit of the pin being a checksum.
Reaver-wps brute forces the first half of the pin and then the second half of the pin, meaning that the entire key space for the WPS pin number can be exhausted in 10,999 attempts. The speed at which Reaver can test pin numbers is entirely limited by the speed at which the AP can process WPS requests. Some APs are fast enough that one pin can be tested every second; others are slower and only allow one pin every ten seconds. Statistically, it will only take half of that time in order to guess the correct pin number.
Installing Reaver from Source Code:
System: Ubuntu
Open terminal and type:
If you've read previous tutorial, You will know that first we have to put our wireless card on monitor mode and then start scanning.
Step 1: Putting Card on Monitor Mode
First kill the programs that may cause issues, then we will put our card into monitor mode.
sudo airmon-ng check kill
sudo airmon-ng start wlan1
wlan1 is the wireless interface in my case, you can check yours by simply typing in terminal.
Jumpstart Wps Pin
iwconfig
Step 2: Scanning the Air for WPS Networks
Airodump-ng has a limitation, It canno detect WPS enabled routers. So, for that purpose we use wash command which installs along with Reaver and helps us scanning for WPS enabled routers.
Just write:
sudo wash -i wlan1mon
It will show a similar output:
Note the 'WPS Locked' column; this is far from a definitive indicator, but in general, you'll find that APs which are listed as unlocked are much more likely to be susceptible to brute forcing. You can still attempt to launch an attack against a network which is WPS locked, but the chances of success aren't very good.
Here,
ESSID/Target: belkin.ffd
BSSID: EC:1A:59:43:3F:FD
Channel: 11
WPS Locked: Yes
In case you're getting an output like this:
Just add '-C' or '–ignore-fcs' with the previous command to skip
- wash -i wlan1mon -C
- wash -i wlan1mon –ignore-fcs
Both will work the same, and ignore FCS packets and you will get previously shown output.
Step 3: Fire up Reaver
After getting the target Ap's BSSID, we will tell Reaver to try WPS pin attack on that specific BSSID only
- reaver -i wlan1mon -b EC:1A:59:43:3F:FD
In some case, BSSID may be cloaked, or duplicated by another attacker. In that case Rever won't be able to successfully conduct WPS pin attack. You'll have to be more precise by providing ESSID and channel number, we earlier noted to Reaver.
- reaver -i wlan1mon -b EC:1A:59:43:3F:FD -c 11 -e 'belkin.ffd'
ESSID may contain spaces, so always include ESSID in quotes.
Step 4: Cracking WPS
This part is actually done by Reaver itself, as we've already provided necessary information to Reaver. If the router is vulnerable to WPS Pin attack, it will show you an output like this:
If Reaver succeeds in Trying one pin after another, WPS pin and corresponding WPA2-PSK key is most like to be broken in couple of hours (3-5).
It is quite funny that WPS was supposed to provide ease and security to the Homeusers, but a vulnerable WPS enabled router allows a potential attacker to break the security with ease. Not only the WPS key, but also the WPA2 PreShared Key that is considerably a lot hard to crack without WPS.
The Ugly Truth about WPS [For Pentesters]
It's important to note that new APs no longer have this vulnerability. This attack will only work on APs sold during that 2006 and early 2012. Since many families keep their APs for many years, there are still many of these vulnerable ones around. So once in a while this technique can be useful.
Supported Wireless Drivers
The following wireless drivers have been tested or reported to work successfully with Reaver-wps:
- ath9k
- rtl8187
- carl19170
- ipw2000
- rt2800pci

- b43
Not Supported
The following wireless drivers/cards have been tested or reported to not work properly with Reaver:

Wi-Fi Protected Setup (WPS) Configuration on WAP121 and WAP321 Access PointsObjective
Wi-Fi Protected Setup (WPS) is a protocol that enables simple establishment of wireless networks without any compromise of network security. It relieves you of the configuration of network names, keys and other cryptographic configurations. WPS can be configured either with a Push Button Configuration or a Personal Identification Number (PIN).
This article explains how to configure WPS Setup on WAP121 and WAP321 Access Points.
Applicable Devices
• WAP121
• WAP321
Software Version
• 1.0.3.4
Configuration of WPS Setup
Step 1. Log in to the web configuration utility and choose Wireless > WPS Setup. The WPS Setup page opens:
Global Configuration
The Supported WPS Version field displays the WPS protocol version that the WAP device supports.
Step 1. Enter the name of the device in the WPS Device Name field.
Octane render 3 08 c4d crack. The following fields are displayed:
• WPS Global Operational Status — Displays whether the WPS protocol is enabled or disabled on the WAP device.
• WPS Device PIN — Displays the system-generated eight-digit WPS PIN for the WAP device. The device PIN is needed when you start WPS enrollment in the client device.
Step 2. (Optional) To generate a new PIN, clickGenerate.
Security Warning: The Enrollee PIN allows an external registry to reconfigure the wireless network so it must only be used by/given to trusted administrators. There is no expiration on this PIN.
Instance Configuration
Jumpstart Wps Pin Locked Password
Step 1. Choose an identifier for the instance from the WPS Instance ID drop-down list. The WPS Instance ID field allows you to choose the instance of WPS on which to enroll the device; however, the WAP only supports one instance of WPS.
Step 2. Check the Enable check box in the WPS Mode field to enable WPS in the instance. If WPS mode is disabled then you have to configure the network configuration each time a new wireless device needs to be added.
Step 3. Choose the virtual access point (VAP) associated with the WPS instance from the WPS VAP drop-down list.
Step 4. Check the Enable check box in the WPS Built-in Registrar field to enable the built-in registrar function. The current device becomes the registrar and can easily add additional wireless clients to your network by automatic assignment of the Wireless Network Name (SSID) and WPA/WPA2-PSK security of the wireless device to the client. If WPS built-in registrar is disabled then the new WPS capable device can register with other registrars in the network.
Step 5. Choose one of these settings from the WPS Configuration State drop-down list.
• Unconfigured — Indicates that the VAP settings are configured by WPS, after which the state changes to Configured.
• Configured — Indicates that the VAP settings cannot be configured by the external registrar and retains the present configuration.
Step 6. Click Save to save the changes.
Instance Status
The following information is available:
• WPS Operational Status — Displays the status of the recent WPS transaction.
• AP Lockdown Status field — Displays whether the current instance is in lockdown state, which blocks the other registrars outside the network. The available options are:
– Temporary — The device is lockdown temporarily and the duration of the lockdown.
