Open Source Intelligence


The focus of this section is to provide helpful resources for OSINT and Passive reconnaissance on a given target. There will be certain tools and sites you might be familiar with that could be applicable in this section, that I have omitted and with good reason.
  1. 1.
    This section is "Passive" recon, which does not entail touching or interacting with your target in any way. For offensive operations, staying off radar is key. But can we check with other sources that may have already scanned out target? You bet.
  2. 2.
    There are many research tools that provide similar output to the ones listed in the later sections. The ones that I have specifically omitted (and will document in another section) are tailored more to defensive operations and contain information like reputation data and historical activity.

OSINT Guides and Methodology
Specific for what you need to look for and how to find it, during the passive recon phase of a penetration test, or the proper way to OSINT.

Volunteer OSINT
There are a few interesting organizations out there that take OSINT researchers and have them help with certain public good tasks like finding missing children or stopping pedophiles. It can be a heavy ask but can really do some good in the world with the skills that we have. Please check out and If you can donate some time to help, please do!
