Hack Wpa Mac

broken image


Yesterday, my friend Victor wanted to crack a wifi network (his, of course) using his MacBook Pro.

If you see 'WPA' or 'WPA2' immediately to the left of the network's name, you can proceed; otherwise, you cannot hack the network. Note the MAC address and channel number of the router. These pieces of information are to the left of the network's name: MAC address — This is the line of numbers on the far-left side of your router. When a device connects to a WPA-PSK Wi-Fi network, something known as the 'four-way handshake' is performed. Essentially, this is the negotiation where the Wi-Fi base station and a device set up their connection with each other, exchanging the passphrase and encryption information. This handshake is WPA2-PSK's Achilles' heel. If you are looking to learn Wi-Fi password hacking, this newly discovered flaw in WPA/WPA2 protocol will surely help you out. 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. Step By Step Hack WPA/WPA2 Wi Fi Passwords Using Aircrack Ng. In the above command it is optional to give the client mac address it is given. Command-c mac This will disconnects the client from access point. Screen shot of a client connected to access point.

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, 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 Google Shopping, it cost less than half an Apple mouse.

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'

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 Free adobe flash player 10.2.0 Download - adobe flash player .... 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.

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.

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'.

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.

In this tutorial, we will automate the wireless cracking process using WiFite. Cracking wireless can exceptionally be tricky when it comes to automation for multiple Access Points. A device like Raspberry Pi could be more compact and helpful in any such cases. Consider a device which can be taken anywhere freely with a binded script in it to check for default/weak wireless passphrases.

WiFite :-

WiFite is an automated WiFi Cracking tool written in Python. It is basically a combination of various famous pentest tools like airmon, aircrack and reaver etc. It is widely used for cracking WEP and WPA (WPS) wireless networks. WiFite version 2 has been released and is likely to be already installed if you are running Kali or Parrot linux distros.

However, since i want this tutorial to be followed by the users of Raspberry Pi and Ubuntu as well, we will make a head-start installing installing WiFite.

Hack Wpa Wifi On Mac

STEP 1

Hack Wifi Wpa Mac

WiFite Installation

Hack Wpa Kali

The project is available on github: https://github.com/derv82/wifite2

Clone the repository using git:

Now, install some pre-requisities required for PMKID attack:

There are some of the required tools for WiFite to properly run and some others are optional. You can find this list on the link given above. The utilities iwconfig and ifconfig would already be installed. However, if you are running short of aircrack suite, that can be installed easily using apt package manager:

Now, to install WiFite:

This will install WiFite as a normal Linux command by creating a symlink to /usr/bin/ directory. You can verify it by printing the manual:

STEP 2

Monitor mode

You would need you wireless card to be operating in monitor mode which can be done with airmon-ng:

STEP 3

WPA/WPA2 Cracking using handshake

The standard way being used by most of the scripts is to capture a handshake and compute the encoded keys to brute force the actual key. However, lately a new method was discovered which uses PMKID to accomplish the task. To Brute force WPA/WPA2 networks using handshake, run the below command:

Arguments:

  • -i: Monitor mode interface to use.
  • --random-mac: Randomize the Wireless Adapter MAC address.
  • --clients-only: Target networks with stations only.
  • --wpa: Target WPA/WPA2 networks only. WPS included.
  • --dict: Wordlist to use for cracking MIC hash.

STEP 4

WPS Cracking

WPS protocol was developed to provide user with the ease of connecting to Access Points. Hownever, the protocol is itself vulnerable on a variety of misconfigured routers. WiFite uses pixie dust and WPS Pin attack against WPS networks. To only target wps networks:

Arguments:

  • --nodeauths: Do not send deauthentication packets.
  • --wps: Only target WPS networks.
  • --wps-only: Only use Pin brute force and pixie dust attack.

STEP 5

WPA/WPA2 cracking using PMKID

Lately, a new method was discovered by Jen Steube for cracking WPA/WPA2. The difference in between handshake and PMKID is that handshake requires the whole 4-way handshake to compute the key to be bruteforced. However, with this new trick an attacker make the Access Point transfer the first EAPOL message which contains the key to be bruteforced. PMKID attack requires two more tools. Install hcxtools:

Then install hcxdumptool:

To crack WiFi Networks using pmkid attack:

Arguments:

  • --pmkid: Only use PMKID to crack wireless networks.
  • --pmkid-timeout: Timeout for first Message to receive.
  • --dict: Wordlist with passwords to brute force.

STEP 6

Cracking Networks

To see which networks are cracked, just execute this command:

Conclusion

WiFite is an awesome wireless cracking tool which automates the cracking stuff using other pentest utilities. It can easily be integrated with a compact device like Raspberry pi and could be very useful tool for a number of reasons.
