Capturing and Cracking WEP WPA/WPA2 With Commview: Wi-Fi: “WiFi” is the short form for Wireless Fidelity. It is a high speed internet and network connection without the use of wires or cables.

28 Jul 2017 Yesterday, my friend Victor wanted to crack a wifi network (his, of course) using his MacBook Pro. I told him to use the excellent VirtualBox images of Kali Linux from. I had just forgotten that:. Using advanced wireless features is impossible from a virtual machine.

Even if he used Kali Linux with a dual boot, installing the wireless drivers to make it work with the airport card is tiresome. Most (not airmon-ng) aircrack-ng tools can be installed on macOS with, but airodump-ng and aireplay-ng crash. So PLEASE, if you want to do other advanced networking things than network sniffing or what is described in this article, do yourself a favour and buy an USB adapter to use with the virtual machine. There is a list on the website of aircrack-ng, and I think the Alfa AWUS051NH v2 is great.

Some people say it is expensive, but last time I checked on, it cost less than half an Apple mouse. What is a WPA attack? There are 3 steps:. Identify the target acces point: name (= BSSID), MAC address (= SSID) and channel ( radio frequency). Sniff the channel in monitor mode to retrieve:. a beacon (easy).

a handshake (= four-way handshake), or some frames of it (hard). Crack the password using the dump What makes the retrieval of the handshake hard is that it appears only when somebody connects to the access point. The good news is that you can deauthentificate people from the wifi network - it’s called wifi jamming and it’s useful to impress a girl and piss off people at Starbucks. When they reconnect, they re-send the handshake.

That adds a Deauth step. Identify the target - with airport “Install”. Aircrack-ng -w wordlist.txt -b TARGETMACADDRESS airportSniff.cap If you don’t have the beacon or the handshake, it will fail accordingly. For wordlists, see below. Deauth As I said, aireplay-ng doesn’t work on a MacBook Pro.

The catch is that aireplay-ng can do a lot of other things besides deauth attacks. You might read that airport cards do not support packet injection, but packet injections are for WEP attacks and nobody uses WEP anymore. We only want to send some deauthentification frames. A ready-to-use application is provided. In fact, you can indentify the target with it too, and it has a really nice GUI. Once you have selected the access point, you can deauth one or multiple users. Stop after about 50 “Deauths”, or else the persons might have trouble to reconnect during several minutes.

It might not work it you are too far from the target as your airport card is far less powerful than the router. Sniff - The good way with tcpdump Using airport presents some issues. You cannot know if you got the beacon and the handshake until you stop the capture and try with aircrack-ng. You capture a lot of unuseful packets too.

Using tcpdump is more efficient. Hashcat -m 2500 -a3 capture.hccapx?d?d?d?d?d?d?d?d Refer to the fot more patterns. Speed hashcat works on the GPU.

On my MacBook Pro, it yields a performance of 5kH/s: it tests 5000 passwords in a second. On a Tesla K20m, the speed is 75kH/s. I managed to crack the 5 last lowercase letters of a wifi password in about 1 minute (26.5 // 75000 = 158 seconds to test them all).

We can see that a GTX 1080 breaks 400kH/s. Wordlists I recommend:. For more efficiency, target the networks with silly names (good examples are “mozart”, “I love cats”, “Harry and Sally”), and avoid the ones called “National Security Agency”, “sysadmin” and “sup3r h4x0r”. Conclusion To find a password, you have to be lucky and have a good idea of its shape. A lot of default wifi passwords are composed of 8 or 10 hexadecimal digits. In average (worst case divided by 2) and according to the above benchmark, with a GTX 1080:.

8 hexadecimal characters take 90 minutes. 10 hexadecimal characters take 16 days. 12 hexadecimal characters take 11 years. If you only want free wifi, just do MAC spoofing on a hotspot that uses web login.
