About this video

Open-source intelligence, or OSINT, is the disciplined process of gathering, analyzing, and disseminating publicly available and legally accessible information about a target. It plays a central role in both cybersecurity reconnaissance and everyday business contexts, such as vetting a potential partner, assessing a vendor, or researching a prospective customer. Because so much information is freely accessible on the internet, OSINT can begin with something as straightforward as a search engine query and still yield substantive findings about an organization's digital footprint. At its core, OSINT operates on the principle that significant intelligence can be derived without any intrusive or unauthorized access. A simple web search can reveal an organization's public-facing infrastructure, affiliated personnel, and online presence. From that starting point, practitioners can layer in dedicated OSINT tools and frameworks that automate and expand the data collection process, enabling a far more comprehensive picture of a target. Understanding how to conduct and apply OSINT effectively is an essential skill for security professionals, analysts, and anyone responsible for organizational risk assessment.

What Open-Source Intelligence Is

When we target a company, one of the first things that we're going to do is look at open-source intelligence to find out information about that company.

Open-source intelligence, or OSINT, means gathering, analyzing, and disseminating publicly available and legally accessible information. So really, we would want to conduct this whenever we're doing business or coordinating with another company. If we plan on using their services, maybe we're planning on partnering with them, maybe it's a customer that we want to sell something to. There are a lot of reasons why we would do this open-source intelligence.

When it comes to reconnaissance, we would want to find out a lot of information about our target, and there's a ton of free information that's out there.

A Simple Example

At its very basic form, I can do a Google search on a target to figure out information from that Google search, and this is an example of OSINT, open-source intelligence. So I'm going to search for TechKnowDJ, which is my example company that I use for a lot of my stuff. And then I can find things like their websites and information on them. Now, that didn't come up, because I haven't fully populated this, but this just gives you an idea of just the beginning levels of doing this open-source intelligence.

And there are many tools out there that can help us with this open-source intelligence, that we can start exploring and get deeper into finding out information around this company.
