Subject: Re: Rule to replace strings
In this same vein, when I encounter new clients I often find that the
users place the company name used in users passwords along
with dictionary words. Is there a good way to prefix and suffix these
names to dictionary words and other mangling rules?
I looked through our defcon crack me if you can threads, and we used a
wordlist, but I don't remember doing much more than adding numbers
to them, might not of needed much more then.
Normally I generate new word-list based on company info... and
I have a phrases dictionary were I find and replace
company_xSux, company_xsucks, blows... f*ckCompany_x
etc... Perhaps a way to combine two word lists (typically short 2-6
chars)... With a large wordlist I would expect it to take a very long
time, as merely suffixing/appending 5 digits to a large wordlist can
take over 24hrs for a single thread, doing dozens of words to the
front and back of that same list would take a very long time as well.
Nonetheless the manual efforts I make seem to work for long passes
that I'd not get with my ordinary JtR rules.
