Doxing is a technique of tracing someone or gathering information about an individual using sources on the internet. Its name is derived from “Documents” or “Docx”. Doxing method is based purely on the ability of the hacker to recognize valuable information about his target and use this information to his benefit. It is also based around the idea that, “The more you know about your target, the easier it will be to find his or her flaws” ~ Urban dictionary.

Such flaws can then be exploited. The exploitation wildly differs depending on the adversary. For example, profiling information can be used for encapsulation attempts by intelligence agencies. If those attempts are tried and fail and you are still enough of an annoyance to your government, expect aggressive demonisation by government paid trolls (and exceptionalism at its current flourishing best).

Doxing is also a part of reconnaissance where it is called 'human intelligence' or 'humint', and its focus is on its shadow side. The techniques can be simple or complex, and are useful for background checks (infiltrant agents will probably remain invisible with these techniques but littler petty tyrant may be detected) [1].

There are tools particularly created for d0xing. I use as little automated tools as possible. Not only because of the risk of poisoning, also because I prefer to pay more attention to little-easily-overlooked-details. The more you rely on auto-anything, the more you overlook. But if you want to use a tool and it is unknown to you, please do some research (possibly) follow the money, where the makers are located, for assessing likelihood of the code being poisoned.

This page collects doxxing resources and if you have one, please do add!

Storing information during research

Store gathered data on an encrypted external disk.


Spies online

You can use the same (or similar) spies online techniques [2] to see yourself through the eyes of the adversaries that might d0x you. That information can then be used to protect yourself from your adversaries as best as you can. And when setting up other, anonymous or pseudonymous identities, these same resources can be used for test-driven-development of the identity.
