How I Used OSINT to Gather Information Like a Hacker
I found my company’s exposed secrets in two hours. No hacking required.
I wanted to see what an attacker could learn about my organization without ever touching our network. No exploits, no passwords, no illegal activity. Just a browser and public search engines.
Within two hours, I had a list of employee emails, internal server names, and a forgotten PDF containing network diagrams. All of it was legally available online. Our team had published it themselves without realizing.
This is OSINT: open-source intelligence. And it is how hackers build their attack maps before ever sending a single packet.
Starting With What You Already Publish
I began on our own company website. I viewed the page source and found developer comments revealing internal file paths and staging server URLs. One comment read, “<!—remove debug=true before launch →” still there after two years.
Then I checked image metadata. A photo of our team’s offsite contained GPS coordinates and the camera model. That alone told an attacker where our employees gathered and what devices they use.
Everything I found was public. We just never thought to look.
