You can also use online distributed WPA/WPA2 handshake cracking tool Now say your prayers and hope the passphrase is present in the dictionary you chose. Use ‘aircrack-ng’ for this: aircrack-ng capture\_file-01.cap -w /media/Pranshu/./dic/dark0de.lst Step 5: After you grab a WPA handshake comes the hard part of brute forcing using a dictionary. If you don’t know the MAC of any associated client, simply ‘broadcast’ a ‘deauth’ to all clients: aireplay-ng -deauth 0 -a mon0 The point is that as he/she will authenticate again shortly, we will capture the handshake without having to wait too long: aireplay-ng -deauth 0 -a -c mon0 airodump-ng -c6 mon0 -w capture_fileĪt this point, you can use ‘aireplay-ng’ to de-authenticate an associated legitimate client from the network. Step 3: Take note of the channel of your target network, dump packets from that channel and save them to a local capture file. Step 2: Take note of the nearest WiFi networks. Step 1: Enable monitor mode on wireless interface airmon-ng start wlan0 In such a case, you may succeed with a dictionary attack.
You might get lucky and your nearest WiFi password may be based on a common dictionary word or number sequence. After downloading the wordlist, password hashes and hashcat, a simple attack can be launched using.
Wordlist, Go Before adding rules to the attack, an attack against the hashes using solely the wordlist can be performed.
How to launch a Dictionary Attack on WPA Handshake A good candidate for this wordlist is phpbb.txt as it contains a number of common passwords and is relatively small in size. UPDATE: I have also posted a video on how capture and crack a WPA hanshake on my YouTube channel. A wordlist is a list of passwords that the tool is going to try, because WPA2 uses AES, there are no meaningful information carried on a Authentication. If you are still brave enough to try a dictionary attack on WPA handshake, here’s the procedure.
success is not guaranteed (the passphrase may not be present in your dictionary).ĭuring my experiments in India, the WiFi passphrases are usually a combination of Hindi and English words or a Hindu name which are, of course, not present in any dictionary that I download no matter how exhaustive it promises to be.WPA uses 128 bit key and 48 bit initialization vector while WEP uses 108 bit key with 24 bit initialization vector. It eliminates all known vulnerabilities in WEP (Wired Equivalent Privacy). going through each word in a dictionary file containing millions of words is time-consuming. It is an encryption system to secure WLAN networks.In all my experiments with penetration testing, I have found dictionary attacks on WPA/WPA2 handshakes to be the most annoying and futile exercises. If you are planning to pentest a WPA/WPA2 network (with No WPS), I have two words for you: Good.
