Aircrack-ng is a network software suite consisting of a detector, packet sniffer, WEP and WPA/WPA2-PSK cracker and analysis tool for 802.11 wireless LANs.It works with any wireless network interface controller whose driver supports raw monitoring mode and can sniff 802.11a, 802.11b and 802.11g traffic.
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.
The attack was soon implemented, and automated tools have since been released. It is possible to perform the attack with a personal computer, off-the-shelf hardware, and freely available software such as aircrack-ng to crack any WEP key in minutes. Cam-Winget et al. [15] surveyed a variety of shortcomings in WEP.
Elcomsoft now has an all-in-one solution that will locate wireless networks, intercept data packets, and crack WAP/WPA2 PSK passwords from any modern laptop with a discrete ATI AMD or NVIDIA ...
Cracking of WEP and WPA keys, both by brute force, and exploiting flaws such as weak scheduling and badly generated keys is supported when a card capable of monitor mode is used, and packet reinjection can be done with a supported card (Prism2 and some Ralink cards). GPS mapping can be performed when an NMEA compatible GPS receiver is attached. [3]
Wi-Fi Protected Access (WPA) is a software/firmware improvement over WEP. All regular WLAN-equipment that worked with WEP are able to be simply upgraded and no new equipment needs to be bought. WPA is a trimmed-down version of the 802.11i security standard that was developed by the IEEE 802.11 to replace WEP.
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. The user can be elicited to provide this sequence by first forcing them offline with the deauthentication attack.
It winds out in cracking WEP utilizing the Fluhrer, Mantin, and Shamir attacks. Besides the basics, including man-in-the-middle attacks , dictionary attacks , and the use of John the Ripper ; Hacking discusses quantum key distribution , Lov Grover's Quantum Search Algorithm , and Peter Shor's Quantum Factoring Algorithm , which are used for ...
