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 Offensive Security and aircrack-ng.
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 MacPorts, butairodump-ng
andaireplay-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.
Wifi password hacking has become popular as people are always in search of the free internet. But due to the advancement of technology, hacking wifi, and cracking passwords have become a difficult task to do. The reason the newer wifi protocols have become safer is due to the implementation of WPA/WPA2 (wifi protected access) protocols. Mar 03, 2020 March 3, 2020 – by Techni Buzz 0 If you are unable to Hack WPA / WPA2 WiFi network using WPS Feature, then you have to crack actual WPA / WPA2 encryption. In this hacking process, handshake packets are the only packets which helps in cracking the network. They contain data that can be used to check that WiFi password / key is valid or not. Nov 25, 2018 The attack to compromise the WPA/WPA2 enabled WiFi networks was accidentally discovered by Steube while he was analyzing the newly-launched WPA3 security standard. This new WiFi hacking method could potentially allow attackers to recover the Pre-shared Key (PSK) login passwords, allowing them to hack into your Wi-Fi network and eavesdrop on the.
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 Google Shopping, it cost less than half an Apple mouse.
Aug 07, 2017 Hacking a WPA/WPA2 WiFi Network Using Mac OS X. Tap to unmute. If playback doesn't begin shortly, try restarting your device. Nov 25, 2018 Discovered by the lead developer of the popular password-cracking tool Hashcat, Jens 'Atom' Steube, the new WiFi hack works explicitly against WPA/WPA2 wireless network protocols with Pairwise Master Key Identifier (PMKID)-based roaming features enabled.
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.
“Install”
Scan
It saves the .cap
capture file and displays the path.
If you don’t have the beacon or the handshake, it will fail accordingly.
For wordlists, see below.
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.
Use JamWiFi. A ready-to-use application is provided there.

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.
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.
When you launch those lines, the first tcpdump
easily captures a beacon and the second waits for the handshake.
Use JamWiFi to deauth some users, and when tcpdump
shows you it got 4 frames or more, Ctrl-C. It appears you can use less that 4 frames, but it depends on the frames you got (for instance 1,2 or 2,3 are sufficient). Anyway you should normally get at least 4. If nothing shows, try to deauth another user.
Now you have everything in capture.cap
. You can also run aircrack-ng
on it.
Like aireplay-ng
, aircrack-ng
offers so many features that it cannot be the best in everything.
We can really speed up the process by using hashcat.
Install with brew

Convert with cap2hccapx
hashcat
doesn’t take cap files, only hccapx files.
Just install hashcat-utils and use cap2hccapx
Alternatively, use this online tool.

To use with a dictionnary:
You have a lot of other options, like brute force:
Refer to the documentation 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 here that a GTX 1080 breaks 400kH/s.

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”.

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.
Aircrack
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.
