goorecon
Purpose:
Using Google to do two things that increase your subject’s attack surface:
Enumerating subdomains, and
Harvesting email addresses.
Discussion:
In the “final” release of BackTrack 4, perhaps just my copy of goorecon was broken. I putzed around hacking the script, but eventually simply renaming goorecon.rb then running
gem install goorecon
solved the issue.
