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.
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]
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 ...
John the Ripper is a free password cracking software tool. [3] Originally developed for the Unix operating system, it can run on fifteen different platforms (eleven of which are architecture-specific versions of Unix, DOS, Win32, BeOS, and OpenVMS).
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.
Newsham partially discovered the Newsham 21-bit WEP attack. The Newsham 21-bit attack is a method used primarily by KisMAC to brute force WEP keys. It is effective on routers such as Linksys, Netgear, Belkin, and D-Link but does not affect Apple or 3Com, as they use their own algorithms for generating WEP keys. Using this method allows for the ...
