12 aircrack-ng is an 802.11 WEP and WPA/WPA2-PSK key cracking program.
13 It can recover the WEP key once enough encrypted packets have been cap‐
14 tured with airodump-ng. This part of the aircrack-ng suite determines
15 the WEP key using two fundamental methods. The first method is via the
16 PTW approach (Pyshkin, Tews, Weinmann). The main advantage of the PTW
17 approach is that very few data packets are required to crack the WEP
18 key. The second method is the FMS/KoreK method. The FMS/KoreK method
19 incorporates various statistical attacks to discover the WEP key and
20 uses these in combination with brute forcing.
21 Additionally, the program offers a dictionary method for determining
22 the WEP key. For cracking WPA/WPA2 pre-shared keys, a wordlist (file or
23 stdin) or an airolib-ng has to be used.
24
26 Common options:
27 -a <amode>
29 Force the attack mode, 1 or wep for WEP and 2 or wpa for WPA-
30 PSK.
31 -e <essid>
33 Select the target network based on the ESSID. This option is
34 also required for WPA cracking if the SSID is cloacked. For SSID
35 containing special characters, see http://www.aircrack-
36 ng.org/doku.php?id=faq#how_to_use_spaces_double_quote_and_sin‐
37 gle_quote_etc._in_ap_names
38 -b <bssid> or --bssid <bssid>
40 Select the target network based on the access point MAC address.
41 -p <nbcpu>
43 Set this option to the number of CPUs to use (only available on
44 SMP systems). By default, it uses all available CPUs
45 -q If set, no status information is displayed.
47 -C <macs> or --combine <macs>
49 Merges all those APs MAC (separated by a comma) into a virtual
50 one.
51 -l <file>
53 Write the key into a file.
54 Static WEP cracking options:
56 -c Search alpha-numeric characters only.
58 -t Search binary coded decimal characters only.
60 -h Search the numeric key for Fritz!BOX
62 -d <mask> or --debug <mask>
64 Specify mask of the key. For example: A1:XX:CF
65 -m <maddr>
67 Only keep the IVs coming from packets that match this MAC
68 address. Alternatively, use -m ff:ff:ff:ff:ff:ff to use all and
69 every IVs, regardless of the network (this disables ESSID and
70 BSSID filtering).
71 -n <nbits>
73 Specify the length of the key: 64 for 40-bit WEP, 128 for
74 104-bit WEP, etc., until 512 bits of length. The default value
75 is 128.
76 -i <index>
78 Only keep the IVs that have this key index (1 to 4). The default
79 behaviour is to ignore the key index in the packet, and use the
80 IV regardless.
81 -f <fudge>
83 By default, this parameter is set to 2. Use a higher value to
84 increase the bruteforce level: cracking will take more time, but
85 with a higher likelihood of success.
86 -k <korek>
88 There are 17 KoreK attacks. Sometimes one attack creates a huge
89 false positive that prevents the key from being found, even with
90 lots of IVs. Try -k 1, -k 2, ... -k 17 to disable each attack
91 selectively.
92 -x or -x0
94 Disable last keybytes bruteforce (not advised).
95 -x1 Enable last keybyte bruteforcing (default)
97 -x2 Enable last two keybytes bruteforcing.
99 -X Disable bruteforce multithreading (SMP only).
101 -s Shows ASCII version of the key at the right of the screen.
103 -y This is an experimental single brute-force attack which should
105 only be used when the standard attack mode fails with more than
106 one million IVs.
107 -z Uses PTW (Andrei Pyshkin, Erik Tews and Ralf-Philipp Weinmann)
109 attack (default attack).
110 -P <num> or --ptw-debug <num>
112 PTW debug: 1 Disable klein, 2 PTW.
113 -K Use KoreK attacks instead of PTW.
115 -D or --wep-decloak
117 WEP decloak mode.
118 -1 or --oneshot
120 Run only 1 try to crack key with PTW.
121 -M <num>
123 Specify maximum number of IVs to use.
124 WEP and WPA-PSK cracking options
126 -w <words>
128 Path to a dictionary file for wpa cracking. Specify "-" to use
129 stdin. Here is a list of wordlists: http://www.aircrack-
130 ng.org/doku.php?id=faq#where_can_i_find_good_wordlists
131 WPA-PSK options:
133 -E <file>
135 Create Elcomsoft Wireless Security Auditor (EWSA) Project file
136 v3.02.
137 -J <file>
139 Create Hashcat Capture file.
140 -S WPA cracking speed test.
142 -r <database>
144 Path to the airolib-ng database. Cannot be used with '-w'.
145 Other options:
147 -H or --help
149 Show help screen
150 -u or --cpu-detect
152 Provide information on the number of CPUs and MMX/SSE support
