This is a collection of wordlists that I've found at different places, they can be used for either cracking or enumeration. I have included the original link to the site where I found it, and also provide a mirror for each of files just in case they should go missing at some point. I will try and keep the lists updated and add new lists when I spot them.
Needless to say: this is work in progress 🙂
Other sites with wordlists
One of my favorite sites has always been skullsecurity.org, it has been a while since it was last updated (2010), but it still have some of the very popular wordlists.
