When running Transforms to return pivots and information in an investigation it is often important that investigators avoid direct contact with the target’s servers or networks for a number of reasons. For example, leaving footprints in the target network’s traffic logs could alert the suspects and, as a result, an investigator may lose important leads. In another scenario, a target’s malware may have a built-in “kill switch” or anti-analysis defense mechanism that shuts it down once it detects an otherwise unresponsive query likely triggered by investigators.
How Maltego Keeps Investigators Anonymous 🔗︎
Used by experts in various industries such as cybersecurity, trust and safety, and law enforcement, Maltego operates with a number of privacy measures to ensure the anonymity of our users. Maltego does not store users’ Transform query details, nor do we reveal users’ identifiable information while they are running Transforms or mining data from public OSINT sources or from online intelligence sources.
The Maltego Desktop Client uses our public Commercial Transform Application Server (CTAS) to run Maltego Standard Transforms for gathering OSINT from common sources on the Internet, querying DNS servers, search engines, social networks, various APIs and other sources documented here. When receiving non-passive Transform queries, target networks only recognize that Maltego is initiating such communications, while the origin of the query (namely the Maltego Desktop application) remains hidden.
The CTAS can be deployed on premise to avoid the sending of data through Maltego’s servers, alternatively users can run Transforms on their own data independent of the internet.
Toggling Privacy Modes on the Maltego Desktop Client 🔗︎
The Maltego Desktop Client provides two privacy modes: Normal and Stealth mode.
During the initial configuration of a new installation, users will be prompted to choose their preferred privacy mode.
Following the initial set-up, users are able to toggle between the two privacy modes during their investigations using the Privacy Mode dropdown options in the primary tool bar’s Investigate tab.
Maltego public Transforms run through the CTAS server, and while both privacy modes maintain users’ anonymity, there is one slight difference.
Normal Privacy Mode 🔗︎
Normal Privacy Mode is designed to provide users with the richest Maltego experience. During an investigation, this mode allows the Maltego Desktop Client to fetch certain data types directly from the internet.
For example, when a URL Entity is returned as an Image Entity, the Maltego Desktop Client fetches the images directly. When a Website Entity is returned, the Client fetches the website favicon from the website and displays it as an Entity overlay.
The graph below shows an example of website favicon overlays and images fetched from URLs.
These fetches are made directly by the Maltego Desktop Client and they bypass our servers. In general, it is safe to keep Maltego activities under Normal Privacy Mode. However, when these fetches happen, a computer’s IP might be exposed in the target’s traffic log. Therefore, care should be taken when investigating URLs for targets who should not be alerted.
Stealth Mode 🔗︎
On the other hand, the Maltego’s Stealth Mode completely restricts the Desktop Client from downloading any data or information directly from the Internet. This means that fetching an Entity image or website overlay will be blocked.
If sensitive investigations are being conducted, under strict confidentiality practices, or users are simply concerned about exposing their IP, it is recommended that users operate Maltego using Stealth Mode.
Please be aware that even while using Stealth Mode, Transforms might still make contact with the target via the public CTAS server or, in the case of local Transforms, a users’ computer during data queries.
Be Aware of Your Privacy Settings 🔗︎
While Maltego continuously works to ensure the security of our users’ investigative environments, we do recommend that all our users be aware of their personal privacy needs and ensure that they take the appropriate measures to protect their anonymity.
