Course 27 - Hacking Web Applications, Penetration Testing, CTF | Episode 11: OSINT, Reconnaissance, and Scanning: Foundations and Tools
In this lesson, you’ll learn about:
The early phases of a penetration test, focusing on intelligence gathering, infrastructure mapping, and active scanning techniques.
Open Source Intelligence (OSINT), collecting actionable data from publicly available sources without directly interacting with the target system.
Google hacking (dorking), using advanced search operators like site:, filetype:, and intitle: to uncover exposed files, misconfigurations, and sensitive information.
The Google Hacking Database (GHDB), a curated repository of search queries used by security researchers to identify common web exposure issues.
Reconnaissance techniques, including:
Identifying authorized IP address ranges to stay within legal testing scope
Domain and subdomain enumeration using tools like dig and DNS reconnaissance utilities
Email enumeration from public sources to assess potential social engineering vectors
Scanning methodologies, transitioning from passive discovery to active probing through:
Host discovery
Port scanning
Service enumeration
Vulnerability identification
Key industry tools used during scanning, including:
Nmap for network and port mapping
Nessus and OpenVAS for vulnerability assessments
Burp Suite and OWASP ZAP for web application testing
Metasploit for controlled exploitation and post-enumeration validation
