Okay, it’s about time. I am finally releasing Fierce 1.0 as a production ready DNS enumeration tool. What does that mean? It means it works. We have now gotten rid of all the kinks that made me think that it was crippled in a way that made me not want to rely on it. So what was fixed? Well, thanks to Jabra we have now patched fierce so that when it does a zone transfer it continues working, in the off chance that someone messes with the zone transfer to fool fierce into stopping before it sees the real output. Alas, it was a small but important issue to fix.
So! Much much more work to be done. Not the least of which is better dictionary support (especially with cnames like www.corp.company.com where “corp” represents a sub dictionary) better enumeration for things like www01, www02, etc… Future support to make it into a PERL module perhaps for bigger projects, etc… Lots to do! It’s a nice release, given that it’s been in beta for a year through countless sub revisions as we worked a lot of the production kinks out.
In other news, Fierce will be part of Backtrack 3.0. No word on when Backtrack 3 will be made production but you can download the beta now. So for those pen testers out there who rely on Backtrack for their toolset you will go without Fierce in your arsenal no longer. Jabra is the one who ported into backtrack as well. Anyway, big thanks to Jabra for the help!
