Frequently Asked Questions

This page provides answers to the most frequently asked questions about Maltego.

If Maltego is Open Source where can I get the source code?

Open source intelligence, not be confused with open source software. Let's Google it and read the very first hit here. Open source intelligence (OSINT) is form of intelligence collection management that involves finding, selecting, and acquiring information from publicly available sources and analyzing it to produce actionable intelligence. In the intelligence community (IC), the term "open" refers to overt, publicly available sources (as opposed to covert or classified sources); it is not related to open-source software or public intelligence.

Do I need to buy a server when I purchase Maltego?

Absolutely not. Both Maltego commercial and community come pre-installed with the ability to use Paterva's servers that are located on the Internet. These servers give access to our standard OSINT transforms as well as the TDS community seed.

What gets logged when I run a transform?

On the Paterva CTAS the following is logged when you run a transform:

  • Your API key
  • IP Address (yours or the proxy you are using)
  • The transform executed
  • The time it executed
  • Your user ID (which gives first name, last name and email address)
  • Note: we do NOT log the questions asked or the results

Some transform use web services contained on the server, these web services log the question asked in a standard web server log and include the following transforms:

  • Transforms that uses meta information contained documents
  • Transforms that uses information in the mirror of sites.

When you register on the community server we log the following:

  • First name
  • Last name
  • Email address
  • Time registered
  • Time first used
  • How many transform you ran
  • MAC address you selected
  • Your operating system type and version, but not details of service packs etc.
  • Maltego client version
How do I install Java 1.8 on my Linux system.

This guide explains how to install Oracle's Java 1.8 on Ubuntu and on Linux Mint.

Which version of Java should I use?

Maltego 4 runs exclusively on Java 1.8, we recommend that you download the latest release of the Oracle version of Java 1.8.

If you are still running an older version of Maltego (Chlorine or Carbon) we recommend that you upgrade to the latest release of Maltego 4 – which can be downloaded from our website.

My proxy settings are not being honoured
by the Maltego client?

Please ensure that your Maltego client is set to use your proxy settings for all network protocols. This can be done by opening the Options menu and clicking the More button under the General Options tab next to the Manual Proxy field. You can then tick the check box Use proxy for all network protocol option. If this is already checked and you are still experiencing proxy issues please contact us via our support channel.

When I run transforms I am asked to enter an API key
but I have already activated my Maltego client.

Many of the transform hub items on the transform hub are from third-party transform providers and require an additional API key from the provider to use that is configured for that specific transforms seed. Your Maltego client license comes with access to all the transform in the PATERVA CTAS transform hub item and all the other free items on the transform hub. To get a API key from a third-party transform providers you will need to contact the provider directly. You will be able to find their contact details on the transform hub.

How do I reset my password for my community account?

You can reset your community password from the Maltego community registration page here.
Please note that our password reset emails often land up in spam so please have a look there if you don't receive your password reset instructions.

How do I move my Maltego client license to another machine?

To move your Maltego license to another machine you will need to email Paterva's support so that your license key activation count can be reset.
Please note that each Maltego client license key is only valid to be used on a single machine at any given time. If this procedure for moving your key is not followed it could result in your key being flagged for repeated use.

How do I add a new transform seed to my Maltego client?

The method for adding transform seeds to your Maltego client has changed slightly with the release of Maltego Chlorine (2015). To add a new transform seed to your client you can go to the Transform Hub and click on the big green plus (+) button. You can then add the seed URL, unique name and display name for the seed and click OK. Finally you can click Install to have the transforms and configurations in that seed installed to your Maltego client.

I did not receive my activation link after I registered
a community account?

The community edition activation email often land up in a Spam folder or similar location. Please inspect these folders or locations. If located there move it to your inbox to avoid future mails being deferred to Spam. If you still can’t find the activation email please contact us via the contact form.

I get the following exception when trying to activate
my Maltego client in Windows: Could not save license file .

In Windows when you activate Maltego the application will create a license file for your client located here: C:\ProgramData\Paterva\Maltego\MaltegoLicense.Lic. If Maltego does not have permission to write to this location your license file will not be saved. If this is the case you will get an error message saying that your license file could not be saved. You can resolve this issue by running Maltego as Administrator.

Where can I find Maltego's message logs?

The Maltego client's log file can be found in the following directories depending on which operating system you are using:

  • Windows: C:\Users\username\AppData\Roaming\.maltego\\var\log\messages.log
  • OS X: /Users/username/Library/Application Support/maltego//var/log/messages.log
  • Linux: /usr/share/maltego/var/log/messages.log
My Maltego/CaseFile is stuck above the Mac menu bar.

Sadly it is a known bug, easiest ways to fix it:

  • Delete your config directory, on Linux it is under ~/.malteg/vx.x/config/ and on Windows at C:\Users\\AppData\Roaming\.maltego\vx.x\config) - this will reset your Maltego to factory settings.
  • Run this applescript: http://www.leonamarant.com/2008/04/02/how-to-get-off-screen-windows-back-on-your-mac-os-x-v105/.
  • Instead of deleting the config you can modify the file config\Windows2Local\WindowManager.wswmgr to co-ordinates that are below the top bar.
There are no transform in my context menu and no
entities in my palette, what should I do?

This sounds like you still need to install the PATERVA CTAS transform seed to your client from the Transform Hub. This can easily be done by going over to the Transform Hub page and clicking the Install button on the first item which is PATERVA CTAS. This will install all the standard Paterva transforms, machines and entities.

I would like to install my Maltego license on a
machine that is re-imaged on a regular basis. How do I do this?

If you are using your Maltego client license on a machine that is frequently being re-imaged you should rather do an offline activation with your license key which will create a license file for your license which can be used multiple times to activate Maltego provided it is only used the machine that it was created with. You can create an license file by choosing the Activate Offline option in the activation wizard from within the Maltego client and then follow the on screen instructions.

JVM Creation Fail?

Generally if this happens it means that the Java Virtual Machine (JVM) could not allocate enough memory for the application. This almost always only occurs on older Java versions, we recommend updating to to the latest release of Java 8. You can download it here. If however you cannot or you have specified the memory as too high within the application, you can easily fix this by running the config application:

  • Windows - located in your start menu under Paterva\Maltego Version\Configure
  • Linux - by running 'maltegotype-memory_config', something like 'maltegocasefile-ce_memory_config'
  • Mac/Other - open a terminal window and navigate to the Maltego install directory, typically at /usr/share/MaltegoTYPE. Navigate to the /maltego-ui/modules/ext/ directory of this and run the following: java -jar Java_Config_App.jar
