Hack WPA-2 PSK Capturing the Handshake


Information Treasure

Hacking WPA-2 PSK involves 2 main steps-

  1. Getting a handshake (it contains the hash of password, i.e. encrypted password)
  2. Cracking the hash.

Now the first step is conceptually easy. What you need is you, the attacker, a client who’ll connect to the wireless network, and the wireless access point. What happens is when the client and access point communicate in order to authenticate the client, they have a 4 way handshake that we can capture. This handshake has the hash of the password. Now there’s no direct way of getting the password out of the hash, and thus hashing is a robust protection method. But there is one thing we can do. We can take all possible passwords that can exists, and convert them to hash. Then we’ll match the hash we created with the one that’s there in the handshake. Now if the hashes match, we know what plain…
