Welcome to Sherlock: Your OSINT Sidekick!

Ever wondered how detectives track people online? Meet Sherlock, a free, open-source tool that makes finding usernames across the web as easy as a few clicks (well, keystrokes!). Whether you’re a curious beginner, a researcher, or just someone who loves techy adventures, Sherlock is your ticket to exploring the world of OSINT (Open-Source Intelligence)—no spy gadgets required! It searches hundreds of social media platforms, forums, and websites to see where a username pops up, saving you hours of manual digging.

In this guide, we’ll walk you through setting it up, using it, and understanding what it can do—all in plain English. Let’s get started!

Getting Sherlock Ready (Installation)

Sherlock runs on Python, so you’ll need Python 3.6 or higher installed on your computer (most systems have it, or you can grab it from python.org). Here’s how to set it up—don’t worry, it’s simpler than it sounds:

1. Download Sherlock:
   Open your terminal (or Command Prompt on Windows) and type:
   

   git clone https://github.com/sherlock-project/sherlock.git

   This grabs Sherlock from its home on GitHub.
2. Move into the Sherlock Folder:
   

   cd sherlock

   Think of this like stepping into Sherlock’s office!
3. Install the Tools Sherlock Needs:
   

   python3 -m pip install -r requirements.txt

   This downloads some extra Python bits (called dependencies) that Sherlock uses to work its magic.

Tip for Beginners: If you hit a snag (like “command not found”), make sure Git and Python are installed. On Windows, you might need to use py -m pip instead of python3 -m pip. Test it with python3 --version first!

Let’s Hunt! (Basic Usage)

Once Sherlock is set up, it’s time to play detective. Open your terminal in the sherlock folder and try this:

sherlock username

Replace username with whatever name you’re curious about—like TechNerd42. Sherlock will zip across 300+ websites (think Twitter, Reddit, Instagram, and more) to find matches. You’ll see a list of hits with direct links—pretty cool, right?

Searching Names Like a Pro

Want to search a full name, like "John Doe"? Just wrap it in quotes:

python3 sherlock "John Doe"

The quotes tell Sherlock it’s one thing, not two separate words. Note: This works best if the person uses their real name as a username.

Supercharge Your Search (Advanced Options)

Sherlock isn’t just a one-trick pony—it’s got some neat extras to make your hunt even better:

• Multiple Usernames: Check a bunch at once:
  

  sherlock username1 username2 username3

• Save Your Findings: Want to keep the results? Use -o to save them to a file:
  

  sherlock -o results.txt username

  Or try --csv for a spreadsheet-friendly format!
• Chatty Mode: Curious what Sherlock’s up to? Add -v for verbose mode:
  

  sherlock -v username

  It’ll spill all the details as it searches.

Fun Example for Beginners:

sherlock -o myfinds.json -v TechNerd42 SuperCoder

This searches for TechNerd42 and SuperCoder, saves results in JSON, and shows you every step. It’s like watching Sherlock solve a case live!

What You’ll Find (Interpreting Results)

Sherlock spits out a list of where it found your username, like:

• [+] Twitter: https://twitter.com/username
• [-] Facebook: Not found

Each + means a hit with a clickable link, while - means no luck there. Beginner Tip: Don’t assume every hit is the same person—usernames can overlap! Cross-check details (like profile pics or bios) to be sure.

Be a Good Detective (Privacy Considerations)

Sherlock is powerful, but with great power comes responsibility. It’s awesome for research or security checks (like seeing where your own username pops up), but:

• Only use it ethically—don’t stalk or harass anyone.
• Check if you’re allowed to dig into someone’s info (e.g., for work or with permission).
• Respect privacy laws in your area.

Think of it like borrowing a magnifying glass: use it to explore, not to invade!

Join the Fun (Contributing to Sherlock)

Sherlock is open-source, meaning anyone can help make it better! Found a bug? Have an idea? Hop over to its GitHub page, report issues, or even tweak the code if you’re feeling brave. Beginners can start by suggesting new sites to search—every little bit helps!
