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.).

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.
