Maltego is a comprehensive tool for graphical link analyses that offers real-time data mining and information gathering, as well as the representation of this information on a node-based graph, making patterns and multiple order connections between said information easily identifiable.
Reconnaissance
Denotes the work of information gathering before any real attacks are planned. The idea is to collect as much interesting information as possible about the target. To achieve this, many different publicly available sources of information are used. The extracted information will often already allow a detailed insight into the affected systems.
The Power of Transforms
Transforms are small pieces of code that automatically fetch data from different sources and return the results as visual entities in the desktop client. Transforms are the central elements of Maltego which enable its users to unleash the full potential of the software whilst using a point-and-click logic to run analyses.
