🇧🇷 OSINT BRAZUCA 🇧🇷

Catalog of Brazilian open sources (public, legal and ready for investigation).
Knowing in order to protect, investigating in order to defend.

Introduction

The OSINT Brazuca Project is a repository created with the aim of gathering information, sources (websites/portals) and OSINT tricks within the Brazilian context 🇧🇷.

OSINT (short for Open source intelligence) is an intelligence model that aims to find, select and acquire information from public sources and analyze it so that, together with other sources, it can produce knowledge. The information collected through open sources has a low cost compared to costly field operations.
