NAME
aircrack-ng - a 802.11 WEP / WPA-PSK key cracker
SYNOPSIS
aircrack-ng [options] <input file(s)>
DESCRIPTION
aircrack-ng is an 802.11 WEP, 802.11i WPA/WPA2, and 802.11w WPA2 key cracking program.
It can recover the WEP key once enough encrypted packets have been captured with airodump-
ng. This part of the aircrack-ng suite determines the WEP key using two fundamental
methods. The first method is via the PTW approach (Pyshkin, Tews, Weinmann). The main
advantage of the PTW approach is that very few data packets are required to crack the WEP
key. The second method is the FMS/KoreK method. The FMS/KoreK method incorporates various
statistical attacks to discover the WEP key and uses these in combination with brute
forcing.
Additionally, the program offers a dictionary method for determining the WEP key. For
cracking WPA/WPA2 pre-shared keys, a wordlist (file or stdin) or an airolib-ng has to be
used.
INPUT FILES
Capture files (.cap, .pcap), IVS (.ivs) or Hashcat HCCAPX files (.hccapx)
OPTIONS
Common options:
-a <amode>
Force the attack mode: 1 or wep for WEP (802.11) and 2 or wpa for WPA/WPA2 PSK
(802.11i and 802.11w).
-e <essid>
Select the target network based on the ESSID. This option is also required for WPA
cracking if the SSID is cloaked. For SSID containing special characters, see
https://www.aircrack-
ng.org/doku.php?id=faq#how_to_use_spaces_double_quote_and_single_quote_etc_in_ap_names
-b <bssid> or --bssid <bssid>
Select the target network based on the access point MAC address.
-p <nbcpu>
Set this option to the number of CPUs to use (only available on SMP systems) for
cracking the key/passphrase. By default, it uses all available CPUs
-q If set, no status information is displayed.
-C <macs> or --combine <macs>
Merges all those APs MAC (separated by a comma) into a virtual one.
-l <file>
Write the key into a file. Overwrites the file if it already exists.
Static WEP cracking options:
-c Search alpha-numeric characters only.
-t Search binary coded decimal characters only.
-h Search the numeric key for Fritz!BOX
-d <mask> or --debug <mask>
Specify mask of the key. For example: A1:XX:CF
-m <maddr>
Only keep the IVs coming from packets that match this MAC address. Alternatively,
use -m ff:ff:ff:ff:ff:ff to use all and every IVs, regardless of the network (this
disables ESSID and BSSID filtering).
-n <nbits>
Specify the length of the key: 64 for 40-bit WEP, 128 for 104-bit WEP, etc., until
512 bits of length. The default value is 128.
-i <index>
Only keep the IVs that have this key index (1 to 4). The default behavior is to
ignore the key index in the packet, and use the IV regardless.
-f <fudge>
By default, this parameter is set to 2. Use a higher value to increase the
bruteforce level: cracking will take more time, but with a higher likelihood of
success.
-k <korek>
There are 17 KoreK attacks. Sometimes one attack creates a huge false positive that
prevents the key from being found, even with lots of IVs. Try -k 1, -k 2, ... -k 17
to disable each attack selectively.
-x or -x0
Disable last keybytes bruteforce (not advised).
-x1 Enable last keybyte bruteforcing (default)
-x2 Enable last two keybytes bruteforcing.
-X Disable bruteforce multithreading (SMP only).
-s Shows ASCII version of the key at the right of the screen.
-y This is an experimental single brute-force attack which should only be used when
the standard attack mode fails with more than one million IVs.
-z Uses PTW (Andrei Pyshkin, Erik Tews and Ralf-Philipp Weinmann) attack (default
attack).
-P <num> or --ptw-debug <num>
PTW debug: 1 Disable klein, 2 PTW.
-K Use KoreK attacks instead of PTW.
-D or --wep-decloak
WEP decloak mode.
-1 or --oneshot
Run only 1 try to crack key with PTW.
-M <num>
Specify maximum number of IVs to use.
-V or --visual-inspection
Run in visual inspection mode. Can only be used when using KoreK.
WEP and WPA-PSK cracking options
-w <words>
Path to a dictionary file for wpa cracking. Separate filenames with comma when
using multiple dictionaries. Specify "-" to use stdin. Here is a list of wordlists:
https://www.aircrack-ng.org/doku.php?id=faq#where_can_i_find_good_wordlists In
order to use a dictionary with hexadecimal values, prefix the dictionary with "h:".
Each byte in each key must be separated by ':'. When using with WEP, key length
should be specified using -n.
-N <file> or --new-session <file>
Create a new cracking session. It allows one to interrupt cracking session and
restart at a later time (using -R or --restore-session). Status files are saved
every 5 minutes. It does not overwrite existing session file.
-R <file> or --restore-session <file>
Restore and continue a previously saved cracking session. This parameter is to be
used alone, no other parameter should be specified when starting aircrack-ng (all
the required information is in the session file).
WPA-PSK options:
-E <file>
Create Elcomsoft Wireless Security Auditor (EWSA) Project file v3.02.
-j <file>
Create Hashcat v3.6+ Capture file (HCCAPX).
-J <file>
Create Hashcat Capture file (HCCAP).
-S WPA cracking speed test.
-Z <sec>
WPA cracking speed test execution length in seconds.
-r <database>
Path to the airolib-ng database. Cannot be used with '-w'.
SIMD selection:
--simd=<option>
Aircrack-ng automatically loads and uses the fastest optimization based on
instructions available for your CPU. This options allows one to force another
optimization. Choices depend on the CPU and the following are all the possibilities
that may be compiled regardless of the CPU type: generic, sse2, avx, avx2, avx512,
neon, asimd, altivec, power8.
--simd-list
Shows a list of the available SIMD architectures, separated by a space character.
Aircrack-ng automatically selects the fastest optimization and thus it is rarely
needed to use this option. Use case would be for testing purposes or when a "lower"
optimization, such as "generic", is faster than the automatically selected one.
Before forcing a SIMD architecture, verify that the instruction is supported by
your CPU, using -u.
Other options:
-H or --help
Show help screen
-u or --cpu-detect
Provide information on the number of CPUs and SIMD support
