ASS to the compromised member on the site dumped. What I like to do is use the additional information such as the IP Addresses and Email Address used under the members to help me complete a DOX report. If you're learning to DOX than you can start here on NulledBB by collecting all the databases dumped.
Let's say you want to DOX a user that goes by the name '1337hacker'. The IP address of this guy is '127.0.0.1'. You can copy this IP address and do a search on all the databases that you have collected. Whichever DB's this IP address is found on will provide additional info such as the Email and IP used to join on THAT site.
This is information that you can note down in your DOX report.
I know this isn't a thread containing a database dump but I didn't know where else to share this kind of topic. It's a tactic I use to get DOX reports on people and I thought it would be a nice little thing to share on NulledBB. Thanks!
