Study Notes

Gathering Intelligence from Websites

Information such as personnel details, email addresses, physical addresses, job postings, and product/service information can be extracted from websites.
Netcraft offers extensive data about website technologies, including hosting companies, server types, and web applications, which can help identify vulnerabilities.
Electronic dumpster diving identifies remnants of defunct websites that can still yield useful information.
Tools like website downloaders allow users to save and analyze websites offline to uncover hidden data.

Tools for Data Collection

The Harvester, part of Kali Linux, gathers emails, subdomains, and employee names, aiding in phishing and Trojan attacks.
The local part of email addresses can be exploited as usernames for further system access attempts.

Penetration Testing

A penetration tester (pentester) is a white-hat hacker conducting simulated attacks to assess an organization’s security.
Information Gathering: Initial phase includes understanding the target's environment before launching attacks.

Penetration Testing Methodology

Initial Meeting: The tester and client define objectives (e.g., test security adherence, employee awareness) and the scope of the test (network, social engineering, application, or physical security).
Types of Testing:
- Black-box testing simulates external attacks with minimal target knowledge.
- Grey-box testing utilizes limited knowledge (e.g., the operating system being used).
- White-box testing involves complete insight into the system, resembling insider threats.
Permission Through Contracts: Securing written authorization detailing systems, risks, timeframe, actions on serious issues, and deliverables is essential.
Execution of the Penetration Test: Conducting the test based on agreed methodologies.
Risk Mitigation Plan (RMP): Documentation of actions taken, results, interpretations, and recommendations to enhance security.
Cleanup: Reversing any changes made during the test to restore the environment.

Information Gathering Methods

Passive Methods: Collect information without engaging the target, such as OSINT - using publicly available data.
Active Methods: Involve direct interaction with the target (e.g., calling personnel).

Tools for Domain Information

nslookup: Retrieves domain or IP address mappings and DNS records with queries like nslookup www.example.com for direct DNS server access.
whois: Queries domain ownership details, including contact information, providing critical insights into the owners of an IP network.
Subdomains: Revealing additional services or servers, which may present security vulnerabilities, highlights the interconnectedness of websites.

Network Topology Information Gathering

traceroute: Tracks the path a packet takes across routers between source and destination, aiding in network diagram creation for understanding infrastructure.
