WPA2crack is the file you want to write to.-c 6 is the channel the Access Point is operating on.Our next step is to focus on one channel and capture sensitive information from it. Let’s use Airodump-Ng command on one channel This allows us to capture all the traffic that your wireless adapter can see and let you know sensitive information such as BSSID (the MAC address of the AP), power, strength, the number of beacon frames, channel, the number of data frames, encryption (if any), and ESSID.Īlways remember that all the visible APs are listed on the upper part of the screenshot, and the clients are listed on the lower part of the screenshot. We can capture the traffic by using the another airodump-ng command. In the next step will Capture Traffic with Airodump-NgĪs of now, our wireless adapter is in monitor mode we can see all the wireless traffic that passes by in the air. This way ALFA card allows us to monitor all of the wireless traffic that pass through the air. This is the same way we put a wired adapter into promiscuous mode. Now first will start our wireless adapter in monitor mode. In this article will use ALFA Network Card as a WIFI Adapter. Let’s Start with Step by Step Let’s start Wi-Fi Adapter in Monitor Mode with Airmon-Ng If we can grab the password at that time, we can then attempt to crack it. Here, when a client (User) authenticates to the access point (AP), the client and the AP go through a 4-step process to authenticate the user to the AP. Researchers found that the weakness in the WPA2-PSK system is that the encrypted password is shared in what is known as the 4-way handshake.

This is stronger encryption algorithm, AES, that is very difficult to crack-but not impossible. However, nowadays WEP encryption is terribly flawed and easily cracked.Īs a replacement of WEP (Wired Equivalent Privacy) encryption, most of the wireless access points use Wi-Fi Protected Access II with a pre-shared key for wireless security, which also known as WPA2-PSK. Wi-Fi was first developed in the late 1990s, with WEP encryption which stands for Wired Equivalent Privacy this was created to give wireless communications privacy and confidentiality. If you want to secure 100% wireless network, then the best method is to disable wireless, but if you use it, then you cannot. In this article will learn how you can crack WPA2 encryption password file.
