Email Address Harvesting
Introduction
Harvesting email addresses is a common part of any external penetration test. Several tools exist that can be easily found with a simple google search that can greatly decrease the amount of time spent combing through search engine results.
I have recently released a new tool into the BackTrack Linux penetration testing distribution that has proven useful on many of my external gigs.
Introducing Jigsaw. Jigsaw is a simple ruby script that searches www.jigsaw.com for employee records and crafts email addresses based on first and last name entries pulled down from their website.
Installation
In Backtrack, installation is as simple as typing:
$ apt-get install jigsaw
Otherwise you can clone the git repository from the above link.
Usage
$ ./jigsaw -h
Jigsaw 1.0 ( http://www.pentestgeek.com/ - http://hdesser.wordpress.com/ )
Usage: jigsaw [options]
example: jigsaw -s Google
-i, –id [Jigsaw Company ID] The Jigsaw ID to use to pull records
-s, –search [Company Name] Name of organization to search for
-r, –report [Output Filename] Name to use for report EXAMPLE: ‘-r google’ will generate ‘google.csv’
-v, –verbose Enables verbose output
Examples:
$ ./jigsaw -s Google
Your search returned more then one company
Jigsaw ID: 215043 – Google, Inc. 6,627 employees.
Jigsaw ID: 224667 – Google Postini Services 149 employees.
Jigsaw ID: 439035 – AdMob Google Inc 2 employees.
Jigsaw ID: 5032028 – Google Inc 1 employees.
…
$ ./jigsaw -i 215043 |grep -i market |grep -i manager
Fyall, Mike - Product Marketing Manager
Ramaswamy, Jenny - Marketing Manager
Satyasai, Serena - Product Marketing Manager
Fu, John - Product Marketing Manager
Shah, Davang - Group Marketing Manager-US Large Advertiser Marketing
...
Reporting
Standard output to the command line is great for searching specific records however the real value in this tool is generating a .csv report that you can open in any spreadsheet application and then filter for records belonging to specific employee or user groups such as Sales & Marketing or Information Systems.
The following query takes about 1 minute to run on my Macbook Pro and pulls 6.5k records from Google.
Royces-MacBook-Pro:jigsaw r3dy$ ./jigsaw.rb -s google.com
Jigsaw ID for google.com is: 215043
Royces-MacBook-Pro:jigsaw r3dy$ ./jigsaw.rb -i 215043 -v -r google

I have uninstalled, reinstalled, restarted, even downgraded once but still nothing.
I am trying to use jigsaw, but when I email harvest it doesn’t display full names and I think it is also doing the same with the emails, not printing full names of email addresses of people
Thanks Royce, I’ll make sure to update my jigsaw before running.
Maybe a dumb question but my reports are all crunched together with elipses between where it cuts off. Any quick advice. Love the program by the way.
Not a dumb quesiton at all. jigsw.com changed the way they display info to unauthenticated users. So the new 1.3 version was patched by Travils Lee to support authentication and then it works just fine.
So make sure to pull down the latest version from the github repo and you should be good to go.
Can you validate that you are using the current stable version 1.2? Run ‘./jigsaw.rb -h’
Thanks!
I am having the same issue. Commands and output are below.
Thanks.
./jigsaw.rb -s google

An impressive share! I have just forwarded this onto a colleague who had been
conducting a little research on this. And he actually bought me breakfast
simply because I stumbled upon it for him… lol.
So allow me to reword this…. Thanks for the meal!
! But yeah, thanks for spending some time to discuss this matter here on your website.

Perhaps you could post the command you ran to generate that error. Otherwise I don’t know what to tell you :)
nice work
