It really depends which way you look at it.
While this tactic used to take up to 8 hours, the newer WPS Pixie-Dust attack can crack networks in seconds. To do this, a modern wireless attack framework called Airgeddon is used to find vulnerable networks, and then Bully is used to crack them.
When attacking a Wi-Fi network, the first and most obvious place for a hacker to look is the type of network encryption.
While WEP networks are easy to crack, most easy techniques to crack WPA and WPA2 encrypted Wi-Fi rely on the password being bad or having the processing power to churn through enough results to make brute-forcing a practical approach. And one weakness many access points have is a feature called Wi-Fi Protected Setup, which we will learn how to exploit in this guide.
This is somewhat more convenient than just resetting the router with the button on the back, but also a massive security hole because of the way many routers deal with implementing this feature. Years later, another attack emerged that remains effective against many routers and greatly reduces the amount of time needed to attack a target.
One of the first practical attacks against WPA- and WPA2-encrypted networks, it totally ignored the type of encryption a network used, exploiting poor design choices in the WPS protocol. Reaver allowed a hacker to sit within range of a network and brute-force the WPS PIN, spilling all the credentials for the router.
Worse, the 8-digit-long PIN could be guessed in two separate halves, allowing for the attack to take significantly shorter than working against the full length of the PIN. While it did require a hacker to be within range of the target Wi-Fi network, it was able to penetrate even WPA and WPA2 networks with strong passwords using an online attack.
This is opposed to an offline attack, such as WPA handshake brute-forcing, which does not require you to be connected to the network to succeed.
While this was a limitation, the benefit is that there is typically no sign of this kind of attack to the average user.
The Reaver attack proved extremely popular, and sincemany routers now have protections to detect and shut down a Reaver-type attack. In particular, these attacks have been greatly slowed by rate-limiting, which forces a hacker to wait several seconds before each PIN attack.
This has led the Reaver attack to be considered deprecated against most modern routers. The Better Attack Method While routers updated some settings to prevent routers from being attacked via brute-force, serious flaws still existed in the way many routers implement encryption.
To do this, we use a function that starts with a number called a "seed," which, after being passed into the function, produces a pseudo-random number.
Since many routers with WPS enabled use known functions to produce random numbers with seed values like "0" or the time stamp of the beginning of the WPS transaction, the WPS key exchange has fatal flaws in the way it encrypts messages.
Integrating many wireless attack tools into a suite well suited for beginners, Airgeddon will allow you to select and configure your wireless card, find and load targeting data from nearby networks, and attack targeted networks — all from the same tool.
There are some trade-offs to using Airgeddon, as the way it passes data between reconnaissance and attack modules requires you to be able to open multiple terminal windows in a GUI desktop environment. If you are using SSH to access your Kali device, you may need to target vulnerable networks using the wash command included in the Reaver tool and pass the data manually to the Bully tool instead.
Since different wireless network cards work better or worse with Reaver or Bully, Airgeddon lets you pass target data between the two scripts and find the sweet spot for your wireless card, the attack module you are using, and the target you are attacking.
We recommend the Panda PAU09or you can check out our guide linked below to see other popular wireless network adapters.
This tool can work very quickly, and if the network is monitored, you will leave evidence in the logs. Open a terminal window, and type the following to clone the repo, change directory to the new folder, and run "airgeddon.
Install Dependencies Airgeddon will detect your OS and terminal resolution. Press return to check on all the tools contained in the framework. Airgeddon will do a check to see what essential tools are installed.
You should try to make sure you have a completely green board before you begin, but in particular, you will need Bully for this attack. To install a missing repo, you have a number of options. The easiest is to follow the format below. When all the results are a green "Ok," press return to proceed to the adapter selection.Jun 30, · [Edit 7/1/16] I wanted to make a few clarifying notes as there have been some questions surrounding this writeup: You only need administrative rights to execute any WMI subscriptions and/or gather files from user folders NOT normally accessible from the current user context (not everything described here needs admin rights).
Mar 07, · As you may have known, it is recommended to choose a channel among 1, 6, 11 for your wireless network. You can also choose other channels and actually some people do. I'm looking for ways to watch mouse and keyboard events on Windows, Linux and Mac from Python. My application is a time tracker.
I'm not looking into the event, I just record the time when it happens. If there are no events for a certain time, say 10 minutes, I assume that .
Jul 20, · So, why write an article called “Cool and Illegal Wireless Hotspot Hacks” that details how to perform hotspot hacks?
Some would say it is irresponsible and enables those with ill intent to hack unsuspecting victim’s machines. Jun 09, · Hi Ram, I am ZERO in scripting/programming and trying very hard to learn python. Can I pass this exam with very basic python skills. Are we supposed to write any new code or how much code do we need to modify for passing the exam?
