Introduction

Open Source Intelligence (OSINT) is a critical skill for cybersecurity professionals, investigators, and ethical hackers. However, access to premium OSINT tools can be a barrier due to high costs. This article explores free and affordable alternatives, along with key commands and techniques for effective OSINT research.

Learning Objectives

  • Identify cost-effective OSINT tools for investigations.
  • Learn essential Linux and Windows commands for OSINT data collection.
  • Understand how to leverage breached data for cybersecurity research.
  1. Free OSINT Tools for Username and Email Searches

Command: Sherlock (Linux)

git clone https://github.com/sherlock-project/sherlock.git 
cd sherlock 
python3 sherlock.py username

Step-by-Step Guide:

1. Install Sherlock via Git.

2. Navigate to the directory.

  1. Run the tool with a target username to scan multiple platforms.
    Why It Matters: Sherlock checks over 300 social media sites for username presence, making it invaluable for footprinting.

  2. Extracting Breached Data with Have I Been Pwned (HIBP)

Command: Curl API Query (Linux/Windows)

curl -s "https://haveibeenpwned.com/api/v3/breachedaccount/[email protected]" -H "hibp-api-key: YOUR_API_KEY"

Step-by-Step Guide:

1. Register for a free HIBP API key.

  1. Use `curl` to check if an email was exposed in breaches.
    Why It Matters: HIBP helps identify compromised credentials, aiding in threat intelligence.

3. Using Infostealers.info for Affordable OSINT

As mentioned in the LinkedIn thread, Infostealers.info offers a budget-friendly alternative to Hudson Rock.
– Cost: $200/year for uncensored data (KYC required).
– Features: Uncensored URLs, partial login/password visibility.
Why It Matters: Provides access to leaked credentials without prohibitive costs.

4. Automating OSINT with Recon-ng (Linux)

Command: Recon-ng Framework

git clone https://github.com/lanmaster53/recon-ng.git 
cd recon-ng 
./recon-ng

Step-by-Step Guide:

1. Install Recon-ng.

2. Load modules (`marketplace install all`).

3. Use `use recon/domains-hosts/bing_domain_web` for domain reconnaissance.

Why It Matters: Recon-ng automates data collection from multiple OSINT sources.

5. Windows-Based OSINT: Maltego Community Edition

Maltego (free version) visualizes relationships between emails, domains, and IPs.

Steps:

1. Download Maltego CE.

  1. Use transforms like `Email to Domain` for investigations.

Why It Matters: Helps map digital footprints visually.

6. Leveraging Breached Data for Threat Hunting

Command: Search Breached Databases (Linux)

python3 breach-parse.py -e [email protected] -b "Collection1"

Step-by-Step Guide:

  1. Use tools like Breach-Parse to query local breach databases.

2. Extract credentials linked to a target.

Why It Matters: Enables proactive credential monitoring.

What Undercode Say:

  • Key Takeaway 1: Free OSINT tools like Sherlock and Recon-ng can replace expensive platforms.
  • Key Takeaway 2: Budget-friendly services (Infostealers.info) provide viable alternatives for paid searches.
    Analysis: The OSINT landscape is evolving, with both open-source and low-cost tools bridging the gap for investigators. While premium tools offer deeper insights, resourceful analysts can achieve similar results with automation and breached data.

Prediction:

As cyber threats grow, demand for affordable OSINT solutions will rise, leading to more freemium models and community-driven tools. Ethical hackers must stay adaptable, leveraging both free and paid resources for effective investigations.
