How To Hack Wifi On Mac Wpa2

/ Comments off

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, but airodump-ng and aireplay-ng crash.

  • Jul 28, 2017  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.

  • Mar 03, 2020  Use handshake packets to crack WPA/WPA2 password. For cracking WPA/WPA2 password, we will use tool named aircrack-ng. Aircrack-ng will unpack the handshake packet and will match the wordlist passwords one by one with the handshake packet. There are multiple ways to crack WPA/WPA2 passwords using wordlist attack.

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.

I used a six-year-old MacBook Pro. A nearby WPA-secured Wi-Fi network. The network should have WPA or WPA2 listed under the ENC column. Your Wi-Fi network is your conveniently wireless. Hacking a WPA/WPA2 Network. It’s not as easy to hack into a WPA wireless network. In order to crack WPA security, you need to obtain a handshake, which occurs when a computer connects to a wireless router. You also make use of a password file which contains a list of passwords in ASCII format.

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.

Wpa2

“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.

This page provides some examples.

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.

How To Crack Wpa2 Wifi

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:

How Can You Hack Wifi

  • 8 hexadecimal characters take 90 minutes.
  • 10 hexadecimal characters take 16 days.
  • 12 hexadecimal characters take 11 years.

How Can Hack Wifi Password

If you only want free wifi, just do MAC spoofing on a hotspot that uses web login.
