🎯 Real-World Scenario: Phishing Site Takedown

Imagine you are a cybersecurity analyst at a mid-sized enterprise. One day, a flood of complaints hits the helpdesk: employees are receiving emails that appear to be from your company’s HR department, asking them to verify their credentials on a suspicious-looking website. This is a classic phishing attack. Your mission? To identify, document, and facilitate the takedown of the phishing site.

🔧 Tools Used

For this mission, we’ll employ a suite of OSINT tools including SpiderFoot, Recon-ng, and AMASS. These tools are renowned for their ability to gather extensive information from various sources, helping you paint a comprehensive picture of the threat landscape.

SpiderFoot: An open-source intelligence automation tool that can scan for thousands of data points across hundreds of sources.
Recon-ng: A full-featured reconnaissance framework that offers a modular approach to gathering OSINT.
AMASS: Focuses on in-depth DNS enumeration, which can be crucial for identifying related domains and subdomains of the phishing site.

🛠️ Step-by-Step Process

Step 1: Initial Reconnaissance with SpiderFoot

Begin by setting up SpiderFoot to gather initial data about the phishing site.

Installation: Install SpiderFoot using pip install spiderfoot.
Run a Scan: Launch SpiderFoot and enter the URL of the phishing site.
Analyze Results: SpiderFoot will provide you with a wealth of data, including IP addresses, domain registrant information, and potential related sites.

Step 2: Deep Dive with Recon-ng

With the initial data in hand, use Recon-ng to dig deeper.

Set Up: Install Recon-ng by cloning the GitHub repository and running the recon-ng command.
Modules: Load relevant modules such as whois_pocs, ipinfo, and ssl.
Execute Commands: Use commands like run to execute modules and show to view results.
Collate Data: Recon-ng will help you collate detailed information about the domain, including contact details for registrants and hosting information.

Step 3: Subdomain Enumeration with AMASS

Finally, use AMASS to uncover any related domains or subdomains that could be part of a broader phishing campaign.

Installation: Install AMASS with go get -u github.com/OWASP/Amass/v3/....
Run Enumeration: Execute amass enum -d [phishingsite.com].
Analyze Subdomains: Review the list of subdomains to identify any other potential phishing sites or infrastructure.

⚖️ Legal/Ethical Reminders

While OSINT tools are immensely powerful, it’s crucial to use them ethically and legally. Always ensure you have permission to probe networks or gather data about specific domains. Avoid accessing or using information that could infringe on privacy rights or violate terms of service.

⚡ TL;DR Summary

Use Case: Identifying and taking down a phishing site.
OSINT Tool: SpiderFoot for initial reconnaissance, Recon-ng for detailed analysis, AMASS for subdomain enumeration.
Red Flag: Avoid accessing information that could violate privacy or legal restrictions.

💡 Expert Insight

One of the significant challenges in OSINT is the risk of false positives. Not all data retrieved is reliable or relevant. It’s essential to corroborate findings with multiple sources to avoid basing decisions on inaccurate information. Overreliance on a single tool or dataset can lead to misinterpretation and misguided actions.
