Wifi hacking

What is WPA ? WPA is the acronym for Wi-Fi Protected Access. It is a security protocol developed by the Wi-Fi Alliance in response to the weaknesses found in WEP. It is used to encrypt data on 802.11 WLANs. It uses higher Initial Values 48 bits instead of the 24 bits that WEP uses. It uses temporal keys to encrypt packets. WPA Weaknesses The collision avoidance implementation can be broken It is vulnerable to denial of service attacks Pre-shares keys use passphrases. Weak passphrases are vulnerable to dictionary attacks. How to Crack WiFI (Wireless) Networks WEP cracking Cracking is the process of exploiting security weaknesses in wireless networks and gaining unauthorized access. WEP cracking refers to exploits on networks that use WEP to implement security controls. There are basically two types of cracks namely; Passive cracking– this type of cracking has no effect on the network traffic until the WEP security has been cracked. It is difficult to detect. Active cracking– this type of attack has an increased load effect on the network traffic. It is easy to detect compared to passive cracking. It is more effective compared to passive cracking.
