Information Gathering

Any information that is used in this document is to outline how easy information about your network can be found, this information should not be used to exploit any host without the permission of the administrator and relevant people/organisations.

This document is very brief, it will not go into detail nor will it discuss how to install and configure the relevant tools to gather such information, this is why companies and outstanding individuals on the internet spead their own time, resources and money to produce such materials for you.

In this document we will use google. Google is one of the most valuable tools on the internet to gather information, also google is well known by all and a 'quick load' site.

Tools that will be used:



Whois: gathers valuable registration information about the domain, nameservers, registrant name, address, agents and much more.

(international dialing code 44)
Searches for .uk can be run at

whois -h ...

Domain Name:

Google Inc

Registrant's Address:
2400 Bayshore Parkway
Mountain View

Registrant's Agent:, Inc. t/a [Tag = ALLDOMAINS]

Relevant Dates:
Registered on: 14-Feb-1999
Renewal Date: 14-Feb-2005
Last updated: 18-Oct-2002

8 Addr:, RTT: 148ms, TTL: 236
9 Addr:, RTT: 148ms, TTL: 236

The DNS tool in samspade allows use to gather details on the DNS servers for the network

06/26/04 20:40:08 dns
Canonical name:

IP Block
The IP Block tool allows user to discover the IP block thats owned by google. A scanner could be used for that block to check for open ports, operating system information, service information etc.

Trace Tool
The traceroute tool will allow you to trace the location of the machine by going through all hops.

For the purpose of this document I have not included the output as this will disclose my ip information

NETCRAFT is a tool that can tell us what operating system and http server is running for a domain. It will also tell us the last time a change was made, IP addresses and the netblock owner

More information can be found on by going to:


By using google you can search for specific information about a company, you could even search the companies site for more information using the following: password

This will search for all pages with password on, a index of these will be displayed once found.

Sorry, maybe I'm missing something, but I don't understand this post. Are you asking a question, or merely posting the results of whois entry? -- J.W.

How do you feel about reposting this in the LinuxQuestions Wiki?

This would allow it to be refined over time and become a useful resource..
There is more room to discuss different aspects of "Information Leakage" there than in the basic forum..
