target_hashes.txt is our input file of hashes.

#GMAIL HACK HASHCAT CRACKED#

-o cracked.txt is the output file for the cracked passwords.

-m 0 designates the type of hash we are cracking (MD5).

We will use the following command line, as illustrated below: hashcat -m 0 -a 0 -o cracked.txt target_hashes.txt /usr/share/wordlists/rockyou.txt In the final step, we can now start cracking the hashes contained in the target_hashes.txt file. The “rockyou” wordlist is now used, as illustrated below: locate rockyou.txt To find them, use the following command line: locate wordlists Kali Linux has numerous wordlists built right into it. This can be seen in the screenshot below:

The character list can be customized to crack the password(s).įinally, Hashcat provides numerous options for password hashes that can be cracked. Hashcat also has specifically designed rules to use on a wordlist file. In general, we need to use both options in most password-cracking attempts when using Hashcat. Some of the most important hashcat options are -m (the hashtype) and -a (attack mode). This is illustrated in the screenshot below: Hashcat can be started on the Kali console with the following command line: hashcat -h. This is also illustrated in the table below: cat target_hashes.txt To do this, we need to type the following command line in the terminal: cat target_hashes.txt The part “tr –d ‘ -‘ “ removes any characters that are a space or hyphen from the output.

The -n option removes the new line added to the end of “Password.” This is important as we don’t want the new line characters to be hashed with our password. In detail, they will then be outputted to a file called “target_hashes.” Each command should be executed in the terminal, as demonstrated below: echo -n “Password” | md5sum | tr -d ” -” > target_hashes.txtĮcho -n “HELLO” | md5sum | tr -d ” -” > target_hashes.txtĮcho -n “MYSECRET” | md5sum | tr -d ” -” > target_hashes.txtĮcho -n “Test1234″ | md5sum | tr -d ” -” > target_hashes.txtĮcho -n “P455w0rd” | md5sum | tr -d ” -” > target_hashes.txtĮcho -n “GuessMe” | md5sum | tr -d ” -” > target_hashes.txtĮcho -n “S3CuReP455Word” | md5sum | tr -d ” -” > target_hashes.txt To start this demonstration, we will create multiple hash entries containing several passwords.

#GMAIL HACK HASHCAT HOW TO#

How to crack a password via a dictionary attack 1. The “rockyou” wordlist found in Kali Linux was used. A dictionary attack will be simulated for a set of MD5 hashes initially created and stored in a target file. The 90+ algorithms can be implemented with performance and optimization in mindĪ small laboratory setup of how to crack a password is presented in the next section.It supports both hex-charset and hex-salt files.The number of threads can be configured and executed based on the lowest priority.This can be used as a brute-force attack variant It can load the salt list from the external file.They recognize recovered hashes from the outfile at startup It is possible to resume or limit sessions automatically.All attack modes can be extended by specialized rules.

It is multi-Algorithm based (MD4, MD5, SHA1, DCC, NTLM, MySQL, etc.).

It is multi-hash and multi-OS based (Linux, Windows and OSX native binaries).

It can be used on Kali Linux and is pre-installed on the system.

Hashing with salt: With this technique, the hashes are randomized by appending or prepending a random string, called a “salt.” This is applied to the password before hashing.

They are similar to lookup tables, except that they sacrifice hash cracking speed to make the lookup tables smaller.

Rainbow tables: Rainbow tables are a time-memory technique.

Reverse lookup tables: This attack allows for a cyber attacker to apply a dictionary or brute-force attack to many hashes at the same time without having to pre-compute a lookup table.

Lookup tables: Hashes are pre-computed from a dictionary and then stored with their corresponding password into a lookup table structure.

Other approaches used to crack passwords: It should be noted that there is no guaranteed way to prevent dictionary attacks or brute-force attacks. These techniques make use of a file that contains words, phrases, common passwords and other strings that are likely to be used as a viable password. Each attempt is hashed and then is compared to the actual hashed value to see if they are the same, but the process can take a long time.ĭictionary and brute-force attacks are the most common ways of guessing passwords.

The simplest way to crack a hash is to try first to guess the password.
