How to optimize Maltego for OSINT Investigations with Maltego Transforms

In my experience, Maltego is an important and useful addition to other OSINT investigation tools and methods.
It is a very versatile tool for a range of very different users. For example, threat intelligence teams, analysts at the SOC, incident response teams, investigators, cyber investigators, prosecutors, and many others. But which Maltego transforms do they use?

Almost all users carry out “OSINT” investigations, but they have different perspectives and needs. The range of professional transformations in Maltego’s “Transform Hub” is therefore just as diverse. From free-to-use transformations to expensive enterprise solutions, everything is available. Last but not least, there is the possibility to write or install your own local transformations. In this post, I will introduce the most important “OSINT” Maltego transformations.

Maltego for Corporate Investigations

The focus of my investigations is “corporate investigations”. For example, for email addresses and social network profiles, I need to identify the possible “real” person behind them. It is also often a matter of identifying the connections between websites, finding users/owners of domains and IP addresses, and other similar topics. So gathering individual information from many sources makes sense, for example, data from SEO tools or information from threat intelligence databases. Therefore, I will limit my consideration of transformations in this post to the investigative benefits rather than aspects of penetration testing. With this perspective in mind, below I evaluate the current transformations for Maltego Classic. I plan to provide additional details about individual transformation providers again from the perspective of investigations.

The User Needs to Understand Maltego Transformations

Using Maltego and finding the best course of action for your own application is not difficult. In my courses, I rarely need longer than one day for this part of the training. However, it is much more important for users to know and understand the installed transformations. This is also the biggest hurdle in the workshops and takes the most time.

I need to know my transformations and (exactly) understand:

Which data sources do these transformations query?
What information can I query and how?
What data do the transformations query, and how do they do it?
What are the expected results?
What transformations can I use with the results?
The first time you try the software, you’ll want to start all existing transformations for an entity. However, this leads to unclear results and frustration. See the image below as an example:

Understanding the Basics of Transformations

The goal is to use transformations in a structured way with knowledge of their fundamentals, and having good documentation from the transform providers would be a real help. Unfortunately however, the different providers have one thing in common: there is often no sufficient documentation of the offered Maltego transformations.
And, this is not only true for the free offers ̶ even the expensive suppliers do not shine here. Of course, there are exceptions:
Luckily, some transformations provide good documentation. For instance, the Paterva transforms are well documented. This explains, for example, why the user cannot compare the search engine results from the transformations with his own Google results. (Patervas uses the Bing API).
Farsight has also published very good documentation.
The vast majority of transformations offered in the “Transform Hub” are subject to a charge. However, some of these providers (marked “purchased separately”) offer queries that are limited in scope, which means that they make sense to use for more basic needs.
I will also address these transformations in this post and a related article. I will also go into the current limitations in more detail.

Five transformations to:

Hunchly Maltego Transforms

Python 2.7 is (still) required to use the transformations.
The transformations access the case data within the Hunchly software.

The starting point is the query of a Hunchly Case. From there you can go to secured pages and photos and to the data and keywords contained therein.
The transformations are still quite simple and improved, but also give a good insight into the possibilities of local transformations.


Maltego needs the right Open Source Intelligence (OSINT) add-on modules – so-called transformations – to show its full strength. These can be transformations bought from a professional provider or local transformations. This post contains the most important selection of transformations for Maltego from my point of view. I will update it as needed.
