Footprinting and Reconnaissance Checklist

Majid,

Footprinting, also known as reconnaissance, is the preparatory phase where an attacker gathers as much information as possible about a target before launching an attack. It is the first step in evaluating the security posture of an organization’s IT infrastructure. The goal is to collect maximum information about a computer system or network to create a security profile blueprint. Footprinting can be passive (gathering information without direct interaction, e.g., through public sources) or active (gathering information with direct interaction, e.g., scanning).

Information Obtained in Footprinting includes:

  • Organization information: Employee details, contact information, branch locations, partners, web links, background, web technologies, news, press releases, legal documents, patents, and trademarks. This can help attackers identify key personnel for social engineering attacks.
  • Network information: Domain and sub-domains, network blocks, network topology, trusted routers, firewalls, IP addresses of reachable systems, Whois records, and DNS records.
  • System information: Web server OS, location of web servers, publicly available email addresses, usernames, and passwords.

Footprinting helps build a hacking strategy by uncovering vulnerabilities and identifying ways to exploit them.

1. Footprinting through Search Engines

Concept: Search engines are primary sources for extracting critical details about a target organization from the internet. They use automated software (crawlers) to index active websites. Advanced search operators, often called “Google Dorks,” create complex queries to find sensitive or hidden information.

Actions & Tools:

  • Perform basic searches:
    • Type the target organization’s name (e.g., “Microsoft”) into search engines like Google, Bing, Yahoo, Ask, AOL, Baidu, Yandex, WolframAlpha, and DuckDuckGo to find physical location, contact addresses, services, and number of employees.
  • Use advanced Google Hacking Techniques (Google Dorks):
    • Understand operators: Use operator:search_term (no spaces).
    • Specific operators:
      • cache: Displays cached web pages.
      • link: Lists pages linking to a specified page.
      • related: Displays similar websites.
      • info: Provides information Google has about a page.
      • site: Restricts results to a specified site or domain (e.g., site:www.certifiedhacker.com).
      • allinurl: Restricts results to pages with all keywords in the URL (e.g., allinurl:google career).
