Mastering OSINT: Unlock the Power of Open Source Intelligence

🎯 Real-World Scenario: Phishing Site Takedown

Imagine you’re a cybersecurity analyst tasked with dismantling a sophisticated phishing campaign targeting your organization. These phishing emails are bypassing traditional security measures, leading unsuspecting employees to a fake login page that harvests their credentials. Your mission is to identify the infrastructure behind this phishing operation and gather actionable intelligence to shut it down effectively.

🔧 Tools Used: SpiderFoot, Recon-ng, AMASS

To tackle this challenge, we’ll dive into a suite of powerful open-source intelligence (OSINT) tools: SpiderFoot, Recon-ng, and AMASS. Each tool offers unique capabilities to uncover digital footprints and map out the infrastructure of malicious actors.

SpiderFoot: The Comprehensive Reconnaissance Tool

SpiderFoot is an automated OSINT tool designed for gathering intelligence about IP addresses, domain names, email addresses, and more. It provides a comprehensive view of the attacker’s digital presence by leveraging multiple data sources.

1. Installation: Install SpiderFoot by following the instructions on their GitHub page.
2. Setup: Launch SpiderFoot and configure it to start a new scan. Enter the phishing domain to kickstart the reconnaissance process.
3. Scan Execution: SpiderFoot collects data across various modules, identifying domain relations, IP addresses, email addresses, and potential server locations.
4. Analysis: Review the generated report to identify the phishing site’s hosting provider, related domains, and any linked IP addresses. This information is crucial for taking down the malicious infrastructure.

Recon-ng: Framework for Web Reconnaissance

Recon-ng is a powerful reconnaissance framework that offers a command-line interface for gathering information from different sources. It’s modular, allowing users to customize their intelligence-gathering strategy.

1. Installation: Clone the Recon-ng repository from Bitbucket.
2. Configuration: Launch Recon-ng and add the phishing domain as a workspace target.
3. Module Selection: Use modules like recon/domains-hosts/shodan_hostname to discover the open ports and services running on the phishing domain’s server. This information can reveal vulnerabilities or misconfigurations.
4. Data Correlation: Analyze the collected data to identify patterns or commonalities with known phishing campaigns.

AMASS: Mapping and Enumeration

AMASS is an OWASP project for network mapping and external asset discovery. It’s particularly effective in identifying subdomains, which can reveal the broader infrastructure used by phishers.

1. Installation: Install AMASS by following the instructions on their GitHub page.
2. Domain Mapping: Run AMASS with the target domain to enumerate subdomains and related assets.
3. Infrastructure Analysis: Use the output to map out the entire infrastructure, identifying potential C2 servers or additional phishing sites.

🛠️ Step-by-Step Process

1. Initial Data Collection: Use SpiderFoot to gather basic intelligence about the phishing domain, such as IP addresses, hosting providers, and related domains.
2. Deep Dive with Recon-ng: Leverage Recon-ng to identify open ports, services, and any exploitable vulnerabilities on the phishing site.
3. Map the Network with AMASS: Enumerate subdomains and map the attacker’s infrastructure to gain a comprehensive view of their operations.
4. Correlate and Report: Correlate findings to confirm the phishing site’s infrastructure. Compile a report detailing the infrastructure, associated risks, and recommended takedown actions.

⚖️ Legal/Ethical Reminders

While OSINT can be a powerful tool, it’s crucial to operate within legal and ethical boundaries. Always ensure you have the necessary permissions before conducting reconnaissance that could impact third-party systems. Avoid intrusive techniques that could be interpreted as hacking or unauthorized access.
