Brazilian Crime Syndicates OSINT Report

I need a thorough OSINT-driven intelligence brief on the five most influential criminal groups operating in São Paulo and Rio de Janeiro. The priority is their leadership structure: who actually calls the shots, and also finding the other members.
For every organisation I must receive a concise yet well-sourced dossier that covers:
• an overview of the group’s history, size, and core illicit activities;
• a clear diagram or narrative of the chain of command;
• full names and known aliases of key leaders;
• verified contact information—active Facebook, Instagram and Telegram profiles, current phone numbers, and any email addresses in circulation.

Please rely on open-source techniques only, combining surface web searches with deep-web forums, breach data, social-media scraping, and Brazilian public records. All findings have to be time-stamped and referenced so that I can retrace the source later.

Deliverables will be:
1. One PDF report (English) summarising each group, its hierarchy, and leader profiles.
2. A spreadsheet or CSV containing raw contact data, links, and source URLs.
3. A brief methodology section explaining the search strings, tools, and validation steps used.

I will consider the job complete once every leader listed comes with at least two independent corroborating sources and all contact details have been checked for activity within the last 30 days.
