Maltego – Paterva: A new train of thought
Maltego is a program that can be used to determine the relationships and real world links between:

People
Groups of people (social networks)
Companies
Organizations
Web sites
Internet infrastructure such as:

Domains
DNS names
Netblocks
IP addresses

Phrases
Affiliations
Documents and files

These entities are linked using open source intelligence.

Maltego is easy and quick to install – it uses Java, so it runs on Windows, Mac and Linux.

Maltego provides you with a graphical interface that makes seeing these relationships instant and accurate – making it possible to see hidden connections.

Using the graphical user interface (GUI) you can see relationships easily – even if they are three or four degrees of separation away.

Maltego is unique because it uses a powerful, flexible framework that makes customizing possible. As such, Maltego can be adapted to your own, unique requirements.
