🎯 Real-world Scenario: Phishing Site Takedown

Imagine you’re part of a cybersecurity team tasked with protecting a large corporation. One day, you receive an alert about a new phishing site impersonating your company’s login page. This site is harvesting user credentials, posing severe risks. Your mission is to gather enough evidence to take the site down, while ensuring no legitimate data privacy laws are violated.

🔧 Tools Used

To tackle this scenario, we’ll utilize three powerful OSINT tools:

SpiderFoot: An all-in-one OSINT automation tool that can collect data from over 100 public sources, perfect for identifying domain details and connections.
Recon-ng: A full-featured web reconnaissance framework with a powerful command-line interface, ideal for gathering information about the phishing domain.
AMASS: A tool used to perform network mapping of attack surfaces and external asset discovery using open source information gathering and active reconnaissance techniques.

🛠️ Step-by-Step Process

Step 1: Initial Domain Investigation with SpiderFoot

Setup SpiderFoot: Install SpiderFoot on your system. It’s available as a web-based interface or command-line tool.
Run a Scan: Use SpiderFoot to perform a scan on the phishing domain. This will help uncover domain registration details, IP addresses, and related subdomains.
Analyze Results: Look for suspicious connections or anomalies in the domain’s registration data, such as recently registered domains or uncommon registrars often used by cybercriminals.

Step 2: Deep Dive with Recon-ng

Install Recon-ng: Clone the tool from its GitHub repository and set it up on your system.
Create a Workspace: Start a new workspace for your investigation to keep data organized.
Gather Domain Information: Use modules like whois_pocs, hosts-hosts, and contacts to extract detailed information about the domain’s ownership and associated email addresses.
Validate Findings: Cross-reference the gathered data with SpiderFoot’s results to identify any inconsistencies or additional leads.

Step 3: Network Mapping with AMASS

Deploy AMASS: Download and install AMASS from its GitHub repository.
Run an Enumeration: Execute a passive reconnaissance scan to map the phishing site’s network infrastructure, identifying external links and related domains.
Review the Output: Focus on the site’s digital footprint, including IP addresses, DNS records, and SSL certificates. This can help pinpoint the hosting provider, aiding in the takedown process.

⚖️ Legal/Ethical Reminders

While OSINT offers powerful capabilities, it’s crucial to operate within legal and ethical boundaries. Always ensure:

Compliance with Laws: Adhere to regional and international data protection laws, such as GDPR and CCPA.
Respect for Privacy: Avoid accessing or using data that violates personal privacy or intellectual property rights.
Responsibility: Use gathered intelligence responsibly, sharing findings only with legitimate authorities or stakeholders.
