1,000 most common US English words (available here)įrom what we could find, the CPU version of hashcat seems to only work with one dictionary at a time (even if you specify two at the command line).To demonstrate the different attacks, the following wordlists will be used: With a single wordlist, the combinator attack will combine each word with itself and every other in the list.įor example, a combinator attack using a single wordlist such as: fastĪs previously mentioned, the hashes can be downloaded from the link provided at the top of the page. It’s also important to mention with this attack that the words in wordlist one will not be tried with wordlist two in reverse order. Also, just because some of the joins don’t make sense, it doesn’t mean you should assume someone wouldn’t choose it as a password. You will get a lot of joined words which do make sense and could potentially be someone’s password. What is a Combinator Attack?Ī combinator attack works by taking words from one or two wordlists and joining them together to try as a password. For example, if wordlist one contained the following: fastĪ combinator attack will try the following: fastcarĪlthough you will get combinations that make no sense, such as “slowbuilding” and “fastbuilding”. In other environments the commands may be different however, the procedure will be the same.

The commands used in this tutorial were run using the Kali Linux operating system by Offensive Security. The password hashes can be obtained here. In this tutorial we will show you how to perform a combinator attack using hashcat.įor demonstration purposes, we will be using the MD5 password hashes from the Battlefield Heroes leak in 2013.
