Breached passwords get published, and if those passwords are leaked with the username, it leads directly to credential stuffing attacks.

#Hashcat speed words persecond password

Password reuse is a very successful attack scenario. The first method is far better, but more important than complex passwords is to have unique passwords. The result of that mangling goes into the password manager too, because I have a lot of passwords and I don’t want to try to remember them. I shift the case, swap letters for random symbols or numbers, combine words, etc. For some things I use a combination of multiple words that occur to me at that moment, and I mangle the characters a bit. Most of the time, the password is generated with a password generator, giving me 15-20 random symbols, which are put directly into my password manager. When I generate a password, I have two ways of handling doing it. But maybe a better exercise would be to try see what it takes to crack a password that is not on a word list. There is enough content out there to explain how and why passwords should be long and complex. If you are wondering, PoohAndPiglet appears in the rockyou word list with three different variants. Changing the digits to something else, would have made this a very different process. The cellphone that you are probably reading this on, has enough power to crack that password in a few seconds because it is on a popular wordlist. Third, this was done on a virtual machine. Second, this took less than 1 second to complete. First, the password poohandpiglet8326 is long, but only lowercase with some numbers. I would like to draw your attention to 3 things at this point.

Use the “–show” option to display all of the cracked passwords reliably Press ‘q’ or Ctrl-C to abort, almost any other key for status $ john –format=PKZIP –wordlist=/usr/share/wordlists/rockyou.txt secrets_hash Rockyou is a famous word list, it has 14 million passwords from previous data breaches.

With that hash value extracted, the second command tells John to use the rockyou wordlist, to try to find the password for the zip file. Ver 78.8 secrets.zip/secretpasswords.txt PKZIP Encr: cmplen=42, decmplen=30, crc=1C0291E First, zip2john extracts a hash value from the archive, like this:

#Hashcat speed words persecond zip file

To crack a zip file with John, I just need to run two commands.

If you were following good password recommendations, John will probably not crack that password any time soon unless you have a good word list to work with. Feed it the zip file, and it will try to crack the password for you. Maybe you found a zip file on a disk tucked away in a box in the back of the closet and you want to know what it is. These tools have legitimate purposes outside of CTFs and hacking.

Each have their strengths, and both are valuable tools in the toolbox.īoth tools are easy to get a hold of, they are free to download on the internet. HashCat, as the name might lead one to think, is helpful when dealing with hashed values. From what I can tell, John is best used for things like zip files, password protected private keys, and things like that. Both are included with Kali Linux, and I use them both. When it comes to cracking hashes and passwords, there are two ruling tools, John the Ripper and HashCat. Cracking Passwords is easy, right up until it isn’t. On those days, it is nice to know how the tools work. Maybe I get a challenge that drops a nice /etc/shadow file in my lap, or zip backup that has someone’s username and password in it. I am always surprised at how rarely I get to crack passwords or brute force things during my pentesting training. Today I am going to write about fun stuff like cracking passwords, brute forcing things, and playing with the tools that are likely to cause a lot of noise. This is part 5 of my Journey of Learning, if you need to catch up, the last post can be found here.

There are also times when it is fun to swing the big meat axe to obliterate obstacles with overwhelming force. There is a time for subtly evaluating a target, spotting a potential vulnerability, and quietly exploiting it to accomplish a goal.
