In order to mount a brute-force or dictionary based WPA password cracking attack on a Wi‑Fi user with WPA or WPA2 enabled, a hacker must first sniff the WPA 4-way handshake.
Network encryption cracking is the breaching of network encryptions (e.g., WEP, WPA, ...), usually through the use of a special encryption cracking software. It may be done through a range of attacks (active and passive) including injecting traffic, decrypting traffic, and dictionary-based attacks.
In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]
Thus, the attacker can send a command, but can never see the response. However, a common command would be to set a password allowing access from elsewhere on the net. An attacker can also be "inline" between A and C using a sniffing program to watch the conversation. This is known as a "man-in-the-middle attack".
A host of security software vendors release anti-hacking products for use on home computers. U.S. President Bill Clinton announces a $1.46 billion initiative to improve government computer security. The plan would establish a network of intrusion detection monitors for certain federal agencies and encourage the private sector to do the same.
[3] [1] These broadcasts are not encrypted and hence may be received by any WiFi access point in range. [ 4 ] [ 5 ] The KARMA attack consists in an access point receiving this list and then giving itself an SSID from the PNL, [ 3 ] [ 6 ] thus becoming an evil twin of an access point already trusted by the client.

Credential recycling is the hacking practice of re-using username and password combinations gathered in previous brute-force attacks. A special form of credential recycling is pass the hash , where unsalted hashed credentials are stolen and re-used without first being brute-forced.
