🎯 Real-world Scenario: Phishing Site Takedown

Imagine your organization receives reports of a phishing website impersonating your brand, attempting to harvest customer credentials. As the cybersecurity analyst, your task is to gather intelligence on this malicious site and compile a detailed report to aid in its takedown. This scenario is a perfect playground to apply your OSINT skills.

🔧 Tools Used

To tackle this challenge, we’ll dive into a few pivotal OSINT tools:

SpiderFoot: An automated OSINT tool that scours the internet for information about a given target.
Recon-ng: A powerful web reconnaissance tool designed to gather information from various sources.
AMASS: A tool for in-depth DNS enumeration and network mapping.

🛠️ Step-by-step Process

Step 1: Initial Footprinting with SpiderFoot

Begin by gathering all available information about the phishing site using SpiderFoot. Launch SpiderFoot, create a new scan, and input the phishing site’s URL as the target. Configure the modules to include domain WHOIS details, IP addresses, and any associated email addresses. Initiate the scan and allow SpiderFoot to work its magic.

Outcome: You’ll receive a comprehensive report detailing the site’s IP address, hosting provider, domain registration information, and more.

Step 2: Recon-ng for Deep Reconnaissance

With the initial data collected, switch to Recon-ng for a more detailed reconnaissance. Open Recon-ng, create a new workspace, and add the phishing site’s domain. Load relevant modules such as recon/hosts-hosts/resolve to resolve IP addresses and recon/contacts-contacts/multi to search for any associated email addresses.

Outcome: Recon-ng will expand on the initial findings, providing additional data like subdomains, potential contact emails, and related domains.

Step 3: Domain Mapping with AMASS

To map the network infrastructure of the phishing site, use AMASS. Run a passive scan to enumerate subdomains and uncover any interconnected domains. AMASS will help you understand the broader network context of the phishing site.

Outcome: You’ll gain insights into the site’s network structure, revealing any additional domains or subdomains linked to the malicious activity.

⚖️ Legal/Ethical Reminders

While OSINT tools are incredibly powerful, they must be used responsibly. Here are some key considerations:

Consent: Ensure you have authorization to investigate the target. Unauthorized probing can breach legal boundaries.
Privacy: Handle personal data with care and comply with privacy laws such as GDPR.
Accuracy: Verify findings from multiple sources to avoid false positives that could lead to incorrect conclusions or actions.
