Yes, you could do this on an isolated box, no need to be on the network... If you're going to do this on a monthly basis, I would take the cracked passwords from each session (found in the john.pot file) and add them to your wordlist for the next month (guard that with your life), make sure to delete the john.pot file after every cracking session. Make sure you get written permission from your manager to do password cracking, you may be violating company policy otherwise.

I have been asked by my manager to setup a password audit. I plan on using john-the-ripper (unix passwords) the basic idea is that we want a list of users that have weak passwords, gut feeling is that a large number of staff have an old default password. we intend to just hit it with a 200K word dictionary, and see what we get. the next step is run this every month and email users that have weak passwords asking them to "please change your password" the question is about the security we setup around the box we run JtR on and the data we find. should this be done on a non-networked box? could this be done on an secure networked box, one that only a few (about 7) trusted staff have login for? any other tips? ------------------------------------------------------------------------ This list is sponsored by: Information Assurance Certification Review Board Prove to peers and potential employers without a doubt that you can actually do a proper penetration test.
