Tool Description : All-in-one OSINT toolkit that helps track usernames across the web, investigate emails and domains, extract metadata, and follow cryptocurrency activity.
TheBigBrother
Quick Overview
What it does
Allows you to search primarily by username, alongside email lookups, domain intelligence, metadata extraction (EXIF), and cryptocurrency tracing.
How to use it
Run the tool from the command line with a target email address, username, domain etc.
Cost
Free.
Account required
No.
Cookies
None (runs locally).
Ownership
Published by “chadi0x” on GitHub, based in Morocco.
Use in Reporting
Mapping digital presence, showing investigative pathways, and supporting corroboration.
What does TheBigBrother do?
TheBigBrother pulls together multiple recon techniques into one place, saving you from jumping between tools.
It’s especially strong for:
Username enumeration across platforms.
Email and domain recon.
Pulling hidden metadata from files.
Following crypto wallet activity.
The lowdown: It’s a versatile, privacy-friendly OSINT toolkit best suited for those comfortable in the command line, who want to streamline their workflow without relying on web-based tools.
How to Use:
1. Run the tool from your terminal and clone the repository from GitHub.
2. Install required dependencies (usually via pip install -r requirements.txt)
3. Input your target (username, email, domain, etc.)
In practice; You could start with a username to map someone’s digital footprint, pivot to email lookups for deeper identity connections. use domain tools to uncover infrastructure, extract EXIF metadata from images for location clues, and investigate crypto wallets for financial trails etc.

Summary
TheBigBrother shines in early-stage investigations, when you’re trying to answer: “Where else does this person exist online?” It’s ideal when you want to quickly pivot between data types and you’re building a broad subject profile, but avoid relying on it when you require deep, specialised analysis and high-confidence attribution.
