While WEP networks are easy to crack, most easy techniques to crack WPA. The Reaver brute-force attack was a radical new weapon for Wi-Fi. You may want to change the MAC address of your adapter with a tool like. It’s exactly what WIBR + – WiFi Bruteforce without root is for, which is capable of accessing WPA and WPA2 networks through brute force. To do this, use different combinations of 8 digits to find out the router’s PIN.
WPA/WPA2 cracking has been a focus point in the community since many years. And we have tools to aim that focus like aircrack and hashcat. Some new advancements have been made to aid that focus in the past couple of years.
So, Cracking WPA/WPA2 has been quite a topic now. In this tutorial, we are going to cover one of the infamous tools 'hashcat' for cracking WPA/WPA2.
Hashcat which is primarily built for brute forcing different kind of hashes using different kind of attack vectors, supports cracking for two of badly known WPA/WPA2 attacks. Well, for the list of available hashes, you can check the hash modes section in the manual:
In previous, you might have seen or even worked with aircrack to crack WPA/WPA2 by capturing a 4-way handshake. But that was not anywhere close to how perfect could this tool be for the purpose. Besides, hashcat is a GPU + CPU maintained tool which makes it a lot more faster.
Mac users interested in Brute force mac programs generally download: RedQuits 2.0 Free In Mac OS X, we use the red X button to close our applications and opened windows; that. Four BitLocker password brute-force cracking tools. Passware Password Recovery Kit. Passware Password Recovery Kit recovers all kinds of lost or forgotten passwords for the office application files, including Excel, Word, Windows 2003, XP, 2K, or NT, RAR. The Reaver brute-force attack was a radical new weapon for Wi-Fi. You may want to change the MAC address of your adapter with a tool like. It’s exactly what WIBR + – WiFi Bruteforce without root is for, which is capable of accessing WPA and WPA2 networks through brute force. This tool even runs on multi-platform: Windows, Linux/Unix, Mac OS X. It works pretty fast and it is easy to use even if you have basic Windows skills. Ophcrack uses rainbow tables to brute force crack the Windows passwords. Term brute force password cracking may also be referred as brute force attack.
In short, if you own a GPU, always go for hashcat or else you could use an online service or buy out some GPU based server on Internet.
We will cover up with two famous WPA/WPA attacks, precisely the cracking of MIC (4-way handshake) and PMKID (1st packet/handshake). So, let's begin.
Installation
Hashcat is built to work on Windows, Linux and as well as on Mac. You can go to hashcat.net and download the binaries and follow the instruction for your operating system. What we are going to do here is clone a fresh copy of hashcat from github and manually install it on a debain based linux.
Preferably, you should use Kali Or Parrot but a similar distro like Ubuntu will work as well.
Update Your Repo's and install the following dependencies:
Clone hashcat from github and move to directory:
Finally, compile the binaries and we are all set with hashcat.
You may try printing the help manual for hashcat to check whether you have it installed perfectly or not.
Hcxtools:
Now, let's clone and compile hcxtools from github. It is basically a set of various files to convert and generate another version of the supplied input. We will use it to convert the captured traffic into a format understandable by hashcat.
First, clone the repo and move the hcxtools directory:
Xmr-stak compiled for mac osx 10.11. And finally, run the make command to compile binaries and make necessary changes in path.
After having the requirements installed, we move to the cracking part. Below this, i am dividing the tutorial into two parts, first we will crack the WPA/WPA2 using MIC aka 4-way handshake. While in second, i'll do cracking using PMKID.
PART A
Let's clear how the MIC cracking actually works. So, in this case, we need a valid 4-way handshake. The handshake consists of many keys that are interchanged during the authentication between the client and access point.
These independent keys are used to generate a common key named 'Message Integrity Code (MIC)'. This generated MIC is used to validate the given password by cracker.
The algorithm to compute MIC is quite long and tricky and i've have covered that up in another tutorial here. So, let the cracking begin.
STEP 1
Conversion to hccapx format
Mac mini for 2014. Supposing you already have a captured 4-way handshake using some tool like airodump, but you still need the proper format to supply it to hashcat. To convert it to a proper format (hccapx), you need another tool.
There are already some online services that you may use: https://hashcat.net/cap2hccapx/
But still in case you are wondering to do it locally, clone the hashcat-utils repo from github:
Finally, compile the binaries. After compiling, you will have the binaries under same directory. The binary file that we need is cap2hccapx.bin. To make sure, you have it correctly compiled, try to execute the file, it will throw you back the syntax:
So, after having it installed, use the below given syntax to convert the .cap file to .hccapx hashcat capture format.
So, this will generate a file by the name 'hashfile.hccapx', which is what we are going to use with hashcat. Now, you may move to whatever directory you want, since will be cracking the final format now.
STEP 2
Cracking WPA/WPA2 (handshake) with hashcat
With hashcat, there is a possibily of various attack vectors. We could do a straight dictionary attack, brute-force attack, combinator attack or even masks attack, i.e. making rules to find various possibilities of trying different characters at different positions.
Anyhow, let's study the actual cracking of WPA/WPA2 handshake with hashcat.
Dictionary Attack:
As named, you need a wordlist for it to work. Considering you have solid list of possible wifi passphrases, or if not, you can download the famous ones: https://www.wirelesshack.org/wpa-wpa2-word-list-dictionaries.html
Launch the following command for dictionary attack:
- -a: specifies cracking mode. In our case it's dictionary mode and '/path/to/dict.txt' is complete path to the wordlist.
- -m: hash mode. Specifies what type of hash we are dealing with.
In Case You Receive issues regarding Intel CPU or 'No devices found/left', use --force argument to force the usage of your device.
Brute-Force Attack:
The Brute-force is different than the dictionary attack. Here, we try to replace every character at every possible position in a specified length from a given charset. For example, in a string of length 8, we can try every character from A-Z at every postion in this string.
That's how brute-forcing works and hence very time-consuming. Launch the following command to start your first attempt for brute-forcing:
- -a: specifies the cracking mode and here the value 3 indicates, we are running a brute-force attack.
- ?d?d?d?d?d?d?d?d: is the brute-forcing rule here. It specifies what kind of values to check, where to replace and also assumes how much time could it take to crack the key.
The above mask i.e. '?d?d?d?d?d?d?d?d' states to check a string of length 8 with a digit at every position. You can study about mask attack here: Hashcat Mask Attack.
PART B
Part A was about the handshake cracking. Whilst now, we are going to crack PMKID with hashcat. The PMKID is located in the 1st packet of 4-way handshake and hence it's kind of more useful because we don't need a complete handshake.
The algorithm to compute PMKID is given which is quite easier than that of MIC.
Let the cracking begin for PMKID.
STEP 1
Getting the PMKID hash
The first thing to proceed with PMKID cracking is the pmkid hash. To generate it we need the first packet of the 4-way handshake. Considering you already have that, we will extract the hash from the captured file.
If you are not aware of how to capture the first packet of 4-way handshake, follow this tutorial.
Let's do the conversion. Execute the below command
This will generate a file by the name pmkid.hash that we will use with hashcat to do the cracking.
STEP 2
Cracking WPA/WPA2 (PMKID) with hashcat
Just like previous part, we will apply the same rules here except for the hash mode argument. The hash mode value for PMKID cracking is 16800.
Dictionary Attack:
Brute Force Mac Firmware Password
As per syntax we have back in the PART A section for dictionary attack, we will use that very same syntax except for the -m argument which defines what kind of hash we want to crack. We will be cracking pmkid (16800) this time.
While this would crack the key by looping through each line given in the wordlist.
Brute-Force Attack:
We will do same here as last section i.e. providing a mask to crack the hash. This time, just to show how powerful these masks could be, i'll use a different one. So, execute the command for brute-force attack:
The above mask will create combinations of string of length 8 with every alphabet at every possible position. And this sounds like a huge combination that may take a lot of time to complete. To make the attack more faster, we can use the GPU.
CPU/GPU
Now, getting into CPU/GPU thing, we just need to know that GPU is a lot more faster than CPU and hashcat have the ability to do cracking on your GPU. Hashcat has following three device modes which can be changed via -d argument:
- 1: CPU which is by default, selected.
- 2: GPU
- 3: DSP, Co-processor.
You can use one of these devices according to what's more suitable for you. For example,
To accomplish PMKID attack on GPU. That's it, i.e. cracking WPA/WPA2 via hashcat.
Conclusion
The conclusion that can be drawn out of all above is that hashcat is not just limited for a number of hashes, infact it's applicable to a wide range of hashes and other possibilities including mixes and concatenated strings. We learned to crack WPA/WPA2 using hashcat.
Besides, hashcat is known of it's power, stability and speed by operating on GPU. It also gives us the possibility of mask attack which let us play with possibilities of testing thousand of thousands strings against the hash.

Brute Force Attack For Mac
Quite a great WinRAR password cracker, isn't it? If you want to recover password more quickly, the popular PassFab for ZIP is a good choice. It uses advanced algorithms to increase the cracking speed by 40X. Importantly, even the latest AES encryption can be easily cracked.
Part 2. Zip/WinZip Password Cracker Online
Password-online.com is also a zip password cracker online, but its services are not free. It charges 10 euros per time.
Before it asks you to pay, it will take a screenshot of the contents of the encrypted zip file, indicating that it has been successfully cracked. Therefore, you just need to upload the zip file you want to crack last time, wait for the website to crack, and then you can get the file after payment.
The shortcoming of this method is also a privacy issue, which is easily attacked by cyber hackers and leads to privacy leaks.
Part 3. Use Free Online Converter to Get Rid of Zip Password
Zip converter is an online zip file password cracker for free. Its principle is to re-convert it to zip format, completely destroying the password in the original zip file. For example, convert .zip to .rar, and do it again, convert rar to zip format.
(Updated: After trying this method in person, I found that it didn't work at all. It still requires a password.)
Step 1. Go to online-convert.com and click on 'Choose Files' to upload the encrypted zip file.
Step 2. After the upload is complete, click on 'Start Conversion'.
Step 3. The encrypted zip file will be uploaded to the server and conversion will begin.
Step 4. After the conversion is complete, download the zip file and open it without using any password.
Note: If your zip file is about trade secrets or personal privacy information, I don't recommend using online conversion services. The online service will generate a copy of the data after the file is uploaded, which will jeopardize your information security.
The Bottom Line
The above is all the contents of zip password cracker. It is rare to see software or web sites with free crack zip passwords, and even if there is, the success rate is not very high. If the file in the encrypted zip is really important, you should consider paying for a professional program to crack the zip password.
