WEP and WPA are the two main security protocols used in Wi-Fi LAN. WEP, or Wired Equivalent Privacy, is a deprecated security protocol that was introduced back in 1997 as a part of the original 802.11 standards. However, it was weak, and several serious weaknesses were found in the protocol. Now, this can be cracked within minutes.

To get unauthorized access to a network, one needs to crack these security protocols. Many tools can crack Wi-Fi encryption. These tools can either take advantage of WEP weaknesses or use brute force password guessing attacks on WPA/WPA2/WPA3.
Wireless hacking tools are of two types. One can be used to sniff the network and monitor what is happening in the network. The other kind of tool is used to hack WEP/WPA keys. These are the popular tools used for wireless password cracking and network troubleshooting.
Aircrack-ng is one of the most popular wireless password cracking tools that you can use for 802.11a/b/g WEP and WPA cracking. Aircrack-ng uses the best algorithms to recover wireless passwords by capturing packets. Once enough packets have been gathered, it tries to recover the password. To make the attack faster, it implements a standard FMS attack with some optimizations.
The company behind the tool also offers an online tutorial where you can learn how to install and use this tool to crack wireless passwords. It comes as Linux distribution, Live CD and VMware image options. You can use any of these. It supports most of the wireless adapters and is almost guaranteed to work. If you are using a Linux distribution, the only drawback of the tool is that it requires deeper knowledge of Linux. If you are not comfortable with Linux, you will find it hard to use this tool. In this case, try Live CD or VMWare image. VMWare Image needs less knowledge, but it only works with a limited set of host OS, and only USB devices are supported.
Before you start using this too, confirm that the wireless card can inject packets. Then start WEP cracking. Read the online tutorial on the website to know more about the tool. If you follow the steps properly, you should be able to successfully crack a Wi-Fi network protected with WEP.
AirJack is a Wi-Fi 802.11 packet injection tool. This wireless cracking tool is very useful in injecting forged packets and taking a network down via a denial of service attack. This tool can also be used for a man-in-the-middle attack on the network.
CloudCracker is an online password cracking tool for cracking WPA-protected Wi-Fi networks. This tool can also be used to crack different password hashes. Just upload the handshake file, enter the network name, and start the tool. This tool has a huge dictionary of around 300 million words to perform attacks.
CrackStation uses massive pre-computed lookup tables to crack password hashes.These tables store a mapping between the hash of a password, and the correctpassword for that hash. The hash values are indexed so that it is possible toquickly search the database for a given hash. If the hash is present in thedatabase, the password can be recovered in a fraction of a second. This onlyworks for "unsalted" hashes. For information on password hashing systems thatare not vulnerable to pre-computed lookup tables, see our hashing security page.
The combination of my past experience, a relatively new WiFi attack that I will explain momentarily, a new monster cracking rig (8 x QUADRO RTX 8000 48GB GPUs) in CyberArk Labs and the fact that WiFi is everywhere because connectivity is more important than ever drove me to research, whether I was right with my hypothesis or maybe just lucky.
In this blog, I demonstrate how easily (you do not need a cracking rig) and with little equipment unsecure WiFi passwords can be cracked, thus hacking the WiFi network .At the end, we will reveal statistics of the cracked hashes and explain how to defend your network from this type of attack. Therefore, it is of utmost importance that we know and understand the cracking method to form an adequate defense.
In simple English, if an adversary wanted to hack/crack a WiFi password, they need to be in the right place (between users and a router) at the right time (when users log in) and be lucky (users entered the correct password and all four packets were sniffed correctly).
Cracking the PMKID hash is ultimately just generating/calculating PMKs with the SSID and different passphrases, then calculating PMKID from the PMK and the other information we obtained. Once we generated a PMKID equal to the PMKID that was retrieved from the AP (Figure 3), the hash is cracked; the passphrases that were used to generate the right PMK that the PMKID was generated from is the correct WiFi password.
Each digit has 10 options (0-9), hence 10**8 possible combinations. One hundred million seems like a lot of combinations, but our monster rig calculates at the speed of 6819.8 kH/s which translates into 6,819,000 hashes per second.A cracking rig is not required as my laptop can get to 194.4 kH/s, which translates into 194,000 hashes per second. That equals more than enough computing power to cycle through the possibilities necessary to crack the passwords. Consequently, it took my laptop roughly 9 minutes to break a single WiFi password with the characteristics of a cellphone number. (10**8)/194,000 = 516 (seconds)/60 = 9 minutes.
The cracking speed for hashtypes differs because of different hash functions and the number of iterations. For example, PMKID is very slow compared to MD5 or NTLM. Nonetheless, it is feasible to crack a PMKID hash if the attacker focuses on a specific network, and the password is not complicated enough.
I hope you enjoyed this blog and that you will take the required steps to secure your WiFi network. And as a reminder, none of the passwords we cracked were used for unauthorized access to these WiFi networks or any other information accessible via these networks.
pardon the expression, but i think it's total crap. two weeks ago, i kept trying the whole day to upload a handshake, but the server was all the time on full load...i thought that the server was processing hundreds or maybe thousands of cracking operations, but noticed later that the number of visits barely increased, which means that there weren't many cracking requests to make the server busy all day...and now it's paying. honestly, i'm a LINUX kind of person, which means that i don't believe in paid services, but rather free stuff for all and the exchange of favors.
Cloud cracking is the future IMHO. Buying expensive hardware pays off when you want to crack passwords, as it speeds much the process of bruteforcing. But not everyone can afford building a dedicated cracking machine. Nowadays you could also capture a handshake with your smartphone, but good luck cracking it (same goes for laptops) ! If you could outsource the cracking process to an external machine for a reasonable price, in a reasonable time, that would be a good thing for every pentester.
This tutorial walks you through cracking WPA/WPA2 networks which use pre-shared keys. I recommend you do some background reading to better understand what WPA/WPA2 is. The Wiki links page has a WPA/WPA2 section. The best document describing WPA is Wi-Fi Security - WEP, WPA and WPA2. This is the link to download the PDF directly. The WPA Packet Capture Explained tutorial is a companion to this tutorial.
WPA/WPA2 supports many types of authentication beyond pre-shared keys. aircrack-ng can ONLY crack pre-shared keys. So make sure airodump-ng shows the network as having the authentication type of PSK, otherwise, don't bother trying to crack it.
There is another important difference between cracking WPA/WPA2 and WEP. This is the approach used to crack the WPA/WPA2 pre-shared key. Unlike WEP, where statistical methods can be used to speed up the cracking process, only plain brute force techniques can be used against WPA/WPA2. That is, because the key is not static, so collecting IVs like when cracking WEP encryption, does not speed up the attack. The only thing that does give the information to start an attack is the handshake between client and AP. Handshaking is done when the client connects to the network.Although not absolutely true, for the purposes of this tutorial, consider it true. Since the pre-shared key can be from 8 to 63 characters in length, it effectively becomes impossible to crack the pre-shared key.
The only time you can crack the pre-shared key is if it is a dictionary word or relatively short in length. Conversely, if you want to have an unbreakable wireless network at home, use WPA/WPA2 and a 63 character password composed of random characters including special symbols.
IMPORTANT This means that the passphrase must be contained in the dictionary you are using to break WPA/WPA2. If it is not in the dictionary then aircrack-ng will be unable to determine the key.
The purpose of this step is to actually crack the WPA/WPA2 pre-shared key. To do this, you need a dictionary of words as input. Basically, aircrack-ng takes each word and tests to see if this is in fact the pre-shared key.
Password cracking is a long-established art, relying on a combination of brute-force processing power and the ability to refine your list down to likely options based on what you know about a target. Many security protocols are vulnerable to brute-forcing attacks, which at its core relies on a few key principals.
Most wireless networks are secured by WPA or WPA2 encryption, which is able to be cracked by capturing a network handshake and using your computer's CPU to brute-force the password. Beside WPA, protocols like SSH and FTP are also vulnerable to brute-forcing, although the methods of brute-forcing can be differentiated between online and offline type attacks. 2ff7e9595c
