Master OSINT: Unlocking Hidden Data for Digital Investigations

Master OSINT: Unlocking Hidden Data for Digital Investigations

🎯 Real-World Scenario: Phishing Site Takedown

Imagine you are a cybersecurity analyst at a mid-sized enterprise. Your organization has been receiving complaints from customers about a phishing website masquerading as your company’s official site. This fake site is harvesting sensitive customer data and damaging your brand’s reputation. Your task is to gather enough information using Open Source Intelligence (OSINT) to aid in the takedown of this phishing site.

🔧 Tools Used

For this digital investigation, we’ll leverage a combination of powerful OSINT tools, including SpiderFoot, Recon-ng, and AMASS.

SpiderFoot

SpiderFoot is an automated OSINT tool that allows you to collect a wide range of information about a website or IP address. It excels at gathering data from multiple sources and presenting it in a coherent manner.

Recon-ng

Recon-ng is a full-featured web reconnaissance framework written in Python. It simplifies the process of conducting reconnaissance by providing a modular interface similar to the Metasploit Framework.

AMASS

AMASS is part of the OWASP Project and is designed to perform in-depth domain enumeration and mapping. It’s particularly useful for discovering subdomains connected to a target domain, which can be critical in identifying all the assets related to a phishing operation.

🛠️ Step-by-Step Process

Step 1: Initial Reconnaissance with SpiderFoot

1. Install SpiderFoot: First, ensure SpiderFoot is installed on your system. You can download it from the SpiderFoot website.

bash
git clone https://github.com/smicallef/spiderfoot.git
cd spiderfoot
pip install -r requirements.txt

1. Run a Scan: Use SpiderFoot to run an initial scan on the phishing domain. This will gather data points such as IP addresses, domain ownership details, and associated technologies.

bash
python sf.py -s <phishing-site-url> -m all

1. Analyze Results: Examine the results for server details, domain registration info, and any related domains or IP addresses.

Step 2: Deep Dive with Recon-ng

1. Setup Recon-ng: Clone the Recon-ng repository and set it up on your machine.

bash
git clone https://github.com/lanmaster53/recon-ng.git
cd recon-ng
pip install -r REQUIREMENTS

1. Create a Workspace: Workspaces help organize data and keep it separated for different investigations.

bash
recon-ng
workspaces create phishing_investigation

1. Gather Domain Info: Use modules within Recon-ng to gather additional details about the phishing domain.

bash
modules load recon/domains-hosts/bing_domain_web
options set SOURCE <phishing-site-url>
options run

1. Identify Subdomains: Use Recon-ng to identify subdomains that may be part of the phishing operation.

bash
modules load recon/domains-hosts/brute_hosts
options set SOURCE <phishing-site-url>
options run

Step 3: Domain Enumeration with AMASS

1. Install AMASS: You can install AMASS using Go or download it directly from OWASP AMASS.

bash
go get -v github.com/OWASP/Amass/v3/...

1. Run AMASS: Use AMASS for comprehensive domain enumeration to uncover associated subdomains and assets.

bash
amass enum -d <phishing-site-url>

1. Review and Correlate: Review the results to identify any patterns or connections between domains that could point to the infrastructure of the phishing campaign.

⚖️ Legal/Ethical Reminders

When using OSINT tools, it is crucial to operate within legal boundaries. Ensure you have explicit permission to investigate any domain or entity, and avoid accessing or collecting data in a manner that could be considered intrusive or illegal. Always respect privacy laws and adhere to ethical guidelines in your investigations.

📚 TL;DR Summary

• Use Case: Phishing site takedown.
• OSINT Tool: SpiderFoot for initial reconnaissance.
• Red Flag: Avoid unauthorized access or data collection that violates legal boundaries.

💡 Expert Insight

While OSINT tools are powerful, be cautious of false positives. Information gathered may not always be accurate or up-to-date. Cross-reference data from multiple sources to ensure validity before taking further action.
