🎯 Real-world Scenario: Phishing Site Takedown

Imagine you’re a cybersecurity analyst at a midsize tech company. Recently, multiple employees have reported suspicious emails leading to what appears to be a phishing site mimicking your company’s login page. Your task is to gather enough intelligence on this malicious site for a possible takedown, ensuring that the threat is neutralized before it compromises sensitive corporate data.

🔧 Tools Used

To tackle this challenge, we will delve into three powerful OSINT tools:

Each tool offers unique capabilities, making them ideal for different aspects of the investigation process.

🛠️ Step-by-step Process

Step 1: Initial Domain Reconnaissance with SpiderFoot

SpiderFoot is an automated reconnaissance tool that excels in gathering intelligence from a myriad of sources. Begin by inputting the phishing domain URL into SpiderFoot:

Setup: Download and install SpiderFoot from its official site.
Execution: Run a scan on the suspicious domain to gather data on IP addresses, DNS records, and even potential related domains.
Analysis: SpiderFoot will return a comprehensive report. Look for any associated IP addresses or domains that could serve as indicators of a larger phishing network.

Step 2: Deep Dive with Recon-ng

Once you have a baseline understanding, it’s time to dig deeper with Recon-ng, a powerful reconnaissance framework:

Setup: Install Recon-ng from its GitHub repository.
Modules: Utilize modules such as recon/domains-hosts/bing_domain_web to enumerate hosts and recon/hosts-hosts/resolve to find IPs.
Data Correlation: Use the data from SpiderFoot to guide your module selection, focusing on those that can uncover additional layers of the phishing operation.

Step 3: Mapping the Network with AMASS

With preliminary data in hand, you can proceed to AMASS for network mapping and exposure analysis:

Setup: Follow the installation instructions on the AMASS GitHub page.
Execution: Use AMASS’s enumeration capabilities to discover subsidiary domains and subdomains, understanding the infrastructure supporting the phishing site.
Assessment: Analyze the results to identify potential weak points in the attacker’s network that could aid in a takedown or further investigation.

⚖️ Legal/Ethical Reminders

While OSINT is a powerful tool for cybersecurity, it must be used ethically and legally. Always ensure that your investigations are compliant with local laws and organizational policies. Unauthorized access to systems or data, even for investigative purposes, is illegal and unethical.
