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. Information collected through open sources is low-cost compared to costly field operations.

🗂️ Structured Dataset

In addition to the Markdown catalog, this repository publishes a structured JSON version in the data/ folder, automatically generated from this README. It allows you to locate sources by input type, that is, what you already have on hand (CPF, CNPJ, license plate, domain, phone...), and by return type, which is the data the source returns.

File	Content
data/sources.json	510 sources in 39 categories, with grouped links. Canonical file.
data/index.json	1,258 flattened links, one record per URL. Search-ready format.
data/taxonomy.json	Controlled vocabulary: 31 input types, 41 return types, and 14 source types.
data/overrides.json	Manual classification corrections.

[!IMPORTANT] sources.json and index.json are generated. Do not edit by hand: the next build overwrites them. Classification corrections go in overrides.json. Each source is identified by the id field (category/name), stable across builds; the dataset does not store its position in the README.
