Shouldn't take too long.


I'm bruteforceing for 14 hours now with 190.000 c/s and did not cracked the hash yet.
Is that normal?

Nope, your doing something wrong.

Thanks Yours31f!

Bruteforcing is very brute. Try running a dictionary attack first. Much, much more efficient that way.

If you need a good list get The Argon list.

Ok, thx.
I have aborted bruteforceing now and started a dictionary attack, which cracked the hash in under 1 second.

What does this have to do with anything?



And, what wordlist did you use for this one?


Debugging is what programmers do to beta software to make it take up more room on your hard drive if it is running too efficiently.

It actually has a lot to do with it if you have beaten it think of her sweet ass and the plot of the movie

Unless you're talking about the biblical figures, then yes. Cain and Abel is used to crack hashes.

Cain can't crack DES
for this one you should use JTR (John The Ripper)
I have tried bruteforcing it, but after 11 and a half hours, no success

guesses: 0 time: 0:11:29:20 (3) c/s: 195442 trying: tisCOKET - tisCOKe1

on P4 3.2 Ghz and 1G of ram

During this I also tried dictionary attack. I've used various wordlists, including TheArgon V1, TheArgon V2, jargon wordlists, language(including 31337 speaking, english, chinese, spanish, etc), technical_dictionary, unix-words, websters.. etc

But still, even if i had 2 instances of JTR running (bruteforcing and dictionary attack), no success. I took a nap leaving the bruteforcer to work.. when I woke up, still no success.

I also made a batch file to run jtr with all the wordlists in a specific folder (I have many wordlists Grin)

None of this worked.

The problem was that this word wasn't in any of those wordlists.
That's very strange because it's a very common word, especially for us Pfft

So, what you have to do is:

Just search for another wordlist. Now I'm not going to tell you which one to use because I would spoil everything. I'm just gonna tell ypu that this list is on a website, near a very comperhensive wordlist. While you're there you can also download the comperhensive one, because I believe that it is of great use, since
it contains many well-known lists, including the Argon wordlist, all the dictionaries in JibbaJabber, milw0rm list, and many many others.

So, now, the challenge is to find this list.
I don't know that if the one who created this challenge did know that the word can only be found there, but if he did, it's a great thing because this challenge made me discover this great wordlist.

In conclusion, this is the final JTR line for this password:

guesses: 1 time: 0:00:00:00 100% c/s: 17702 trying:

it took less than a second.

Oh, and a final piece of advise:

When you have to do an off-line password cracking.. that is you have the hash on your system and you're running the cracking on your machine, best is to run a bruteforcer from start, and leave it running. Only then try dictionary-attacks on the hash. This way, if your dictionary attacks don't work, you did'n waste any time because the bruteforcer was already running, and you don't have to start it now, when you already have spent some time with dictionary-attacks.

DO NOT do this unless the cracking software is runing on your machine (bruteforcing takes pretty large amount of system resources, so if you're using another system, the sysadmin might notice a strange increase in resource usage"
oh.. and for those who will say.. "but you can tell the cracking software not so use so many resources" : If it doesn't use as much resources as it can, it won't be effective at all. Woud you crack a pass with 100 c/s ? No you wouldn't.. well, not in a few months, years - depending on the password Smile

Thank you for reading this, and I hope it helps

oh.. and a little off-topic question.. can JTR only crack passwords up to 8 characters?





It's the final CountDowN

No, there is no limit to the password length. However, for most machines the password entropy becomes too much for the machine to crack a password over 8 or 9 characters in a decent amount of time.

As for running the bruteforcer in the background, that makes no difference at all. The bruteforcer is then fighting for resources with the wordlist attacks, which evens out in the end anyways. Afaik, it should be identical time no matter whether or not you ran them parallel, unless JTR only uses a single core/thread.


The irony of man's condition is that the deepest need is to be free of the anxiety of death and annihilation; but it is life itself which awakens it, and so we must shrink from being fully alive.
