Wifi Crack For Mac Os

 

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.

Cracking WPA2 / WEP Wifi / Aircrack 10 seconds guide. For Mac OSX - Aircrack Commands. Once identified use Google to search for Apple Mac OS drivers for your WiFi chipset/product, in my case this was a RTL8191SU based dongle and it had a working Apple Mac OS X driver for the most current Mac OS X Mountain Lion version (Apple Mac OS X 10.8.4). A simple download and install, followed by a reboot did the trick as shown below. WiFi Crack for Mac allows users to crack open any kind of wireless network with utmost ease. This WiFi Cracker tool comes with powerful command line tools which help in collecting the WEP password from the network. All 64-bit Mac devices containing OS X 10.7 and higher versions support this tool.

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”

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.

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.

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

Today, one can only imagine what they would do without the internet and WiFi. While wired connections are still pretty much prevalent, nothing really beats the convenience of WiFi and wireless networks are also catching up in terms of speed. In this article, we are going to talk about how you can get the most out of your WiFi network by monitoring the performance of your network and improving it with these Wi-Fi analyzing tools for macOS.

Note: Most of these apps only work with the built-in WiFi adapter of your Mac and do not work with an external adapter.

6. Honorable Mentions

WireShark is an open source and very powerful network analyzer used mainly by network admins and developers. Although it comes with a steep learning curve, it is one of the best packet analyzer apps available. WireShark is also capable of working in monitor mode, thereby letting you see what other devices are browsing/watching on your network. While normally you’d need an external WiFi adapter to these kinds of things, most Macs have a network card that supports monitor mode which overall works out pretty well.

Usb Wifi For Mac

JamWiFi is another free little tool which can not only analyze devices connected to your wireless network, but you can also disconnect them from using your WiFi. But it also comes with a downside which is it will also disconnect you and you have to reconnect again.

WiFi Signal Strength Explorer is a handy little utility which unlike the normal WiFi icon, shows you the strength of connection via dots/percent in the menu bar and by clicking it, you can access some basic details about your current network.

Wrapping Up: WiFi Analyser for Mac

So these were the best WiFi analyzer applications available for macOS and here’s a little recap. For casual use or not too deep analysis, the Wireless Diagnostics seem to work just fine. If you need something quick that shows you details about your connected network just from your menubar, check out WiFi Signal. As a WiFi analyzing tool, WiFi Explorer has got everything you might need. However, if you are a sucker for extra features, WiFi Scanner provides the most for your money.
