Aircrack-ng

Aircrack-ng is a comprehensive set of
network security tools that includes,
aircrack-ng (which can cracks WEP and WPA
Dictionary attacks), airdecap-ng (which can
decrypts WEP or WPA encrypted capture
files), airmon-ng (which places network cards
into monitor mode, for example when using
the Alfa Security Scanner with rtl8187),
aireplay-ng (which is a packet injector),
airodump-ng (which is a packet sniffer),
airtun-ng (which allows for virtual tunnel
interfaces), airolib-ng (which stores and
manages ESSID and password lists),
packetforge-ng (which can create encrypted
packets for injection), airbase-ng (which
incorporates techniques for attacking clients)
and airdecloak-ng (which removes WEP
cloaking). Other tools include airdriver-ng (to
manage wireless drivers), airolib-ng (to store
and manages ESSID and password lists and
compute Pairwise Master Keys), airserv-ng
(which allows the penetration tester to
access the wireless card from other
computers). Airolib-ng is similiar to easside-
ng which allows the user to run tools on a
remote computer, easside-ng (permits a
means to communicate to an access point,
without the WEP key), tkiptun-ng (for WPA/
TKIP attacks) and wesside-ng (which an an
automatic tool for recovering wep keys).
Like most of the security tools in our list,
Aircrack also has a GUI interface – called
Gerix Wifi Cracker. Gerix is a freely licensed
security tool under the GNU General Public
License and is bundled within penetration
testing Linux distributions such a kali linux ,
BackTrack And Backbox. The Gerix GUI has
several penetration testing tools that allow
for network analysis, wireless packet
capturing, and SQL packet injection.
