Sherlock OSINT Username Search

Hunt down social media accounts by username across 400+ social networks using the Sherlock Project.

When to Use

• User asks to find accounts associated with a username
• User wants to check username availability across platforms
• User is conducting OSINT or reconnaissance research
• User asks "where is this username registered?" or similar

Requirements

• Sherlock CLI installed: pipx install sherlock-project or pip install sherlock-project
• Alternatively: Docker available (docker run -it --rm sherlock/sherlock)
• Network access to query social platforms

Procedure

1. Check if Sherlock is Installed

Before doing anything else, verify sherlock is available:

sherlock --version

If the command fails:

• Offer to install: pipx install sherlock-project (recommended) or pip install sherlock-project
• Do NOT try multiple installation methods — pick one and proceed
• If installation fails, inform the user and stop

2. Extract Username

Extract the username directly from the user's message if clearly stated.

Examples where you should NOT use clarify:

• "Find accounts for nasa" → username is nasa
• "Search for johndoe123" → username is johndoe123
• "Check if alice exists on social media" → username is alice
• "Look up user bob on social networks" → username is bob

Only use clarify if:

• Multiple potential usernames mentioned ("search for alice or bob")
• Ambiguous phrasing ("search for my username" without specifying)
• No username mentioned at all ("do an OSINT search")

When extracting, take the exact username as stated — preserve case, numbers, underscores, etc.

3. Build Command

Default command (use this unless user specifically requests otherwise):

sherlock --print-found --no-color "<username>" --timeout 90

Optional flags (only add if user explicitly requests):

• --nsfw — Include NSFW sites (only if user asks)
• --tor — Route through Tor (only if user asks for anonymity)

Do NOT ask about options via clarify — just run the default search. Users can request specific options if needed.

4. Execute Search

Run via the terminal tool. The command typically takes 30-120 seconds depending on network conditions and site count.

Example terminal call:

{
  "command": "sherlock --print-found --no-color \"target_username\"",
  "timeout": 180
}

5. Parse and Present Results

Sherlock outputs found accounts in a simple format. Parse the output and present:

1. Summary line: "Found X accounts for username 'Y'"
2. Categorized links: Group by platform type if helpful (social, professional, forums, etc.)
3. Output file location: Sherlock saves results to <username>.txt by default

Example output parsing:

[+] Instagram: https://instagram.com/username
[+] Twitter: https://twitter.com/username
[+] GitHub: https://github.com/username

Present findings as clickable links when possible.

Pitfalls

No Results Found

If Sherlock finds no accounts, this is often correct — the username may not be registered on checked platforms. Suggest:

• Checking spelling/variation
• Trying similar usernames with ? wildcard: sherlock "user?name"
• The user may have privacy settings or deleted accounts

Timeout Issues

Some sites are slow or block automated requests. Use --timeout 120 to increase wait time, or --site to limit scope.

Tor Configuration

--tor requires Tor daemon running. If user wants anonymity but Tor isn't available, suggest:

• Installing Tor service
• Using --proxy with an alternative proxy

False Positives

Some sites always return "found" due to their response structure. Cross-reference unexpected results with manual checks.

Rate Limiting

Aggressive searches may trigger rate limits. For bulk username searches, add delays between calls or use --local with cached data.

Installation

pipx (recommended)

pipx install sherlock-project

pip

pip install sherlock-project

Docker

docker pull sherlock/sherlock
docker run -it --rm sherlock/sherlock <username>

Linux packages

Available on Debian 13+, Ubuntu 22.10+, Homebrew, Kali, BlackArch.

Ethical Use

This tool is for legitimate OSINT and research purposes only. Remind users:

• Only search usernames they own or have permission to investigate
• Respect platform terms of service
• Do not use for harassment, stalking, or illegal activities
• Consider privacy implications before sharing results

Verification

After running sherlock, verify:

1. Output lists found sites with URLs
2. <username>.txt file created (default output) if using file output
3. If --print-found used, output should only contain [+] lines for matches

Example Interaction

User: "Can you check if the username 'johndoe123' exists on social media?"

Agent procedure:

1. Check sherlock --version (verify installed)
2. Username provided — proceed directly
3. Run: sherlock --print-found --no-color "johndoe123" --timeout 90
4. Parse output and present links

Response format:

Found 12 accounts for username 'johndoe123':

• https://twitter.com/johndoe123

• https://github.com/johndoe123

• https://instagram.com/johndoe123

• [... additional links]

Results saved to: johndoe123.txt

User: "Search for username 'alice' including NSFW sites"

Agent procedure:

1. Check sherlock installed
2. Username + NSFW flag both provided
3. Run: sherlock --print-found --no-color --nsfw "alice" --timeout 90
4. Present results
