Password Cracking Each student should be able to access* one PassXX.hash file. This file contains 4 unsalted md5 password hashes (md5 is commonly used for hashing passwords, though it is a bit weak for modern use. It is very important to salt passwords before hashing them, since leaving them unsalted makes them easier to crack. However, many sites fail to do this). Your assignment is to use Hashcat (or another password cracking or password "recovery" tool) to retrieve the original passwords from the hashes, and submit the password/hash pairs. Each set of hashes contains 1 very easy password and 3 slightly challenging passwords of differing format. Link to hashcat: https://hashcat.net/hashcat/ Note: You will also need one or more dictionaries to perform a dictionary attack. *access: Files are accessible based on your last name. You should see a large number of files that are not accessible due to your account having a wrong last name, and one file that is accessible that lacks…
