Reconnaissance for Ethical Hackers

5 (1)
By: Glen D. Singh

Overview of this book

This book explores reconnaissance techniques – the first step in discovering security vulnerabilities and exposed network infrastructure. It aids ethical hackers in understanding adversaries’ methods of identifying and mapping attack surfaces, such as network entry points, which enables them to exploit the target and steal confidential information. Reconnaissance for Ethical Hackers helps you get a comprehensive understanding of how threat actors are able to successfully leverage the information collected during the reconnaissance phase to scan and enumerate the network, collect information, and pose various security threats. This book helps you stay one step ahead in knowing how adversaries use tactics, techniques, and procedures (TTPs) to successfully gain information about their targets, while you develop a solid foundation on information gathering strategies as a cybersecurity professional. The concluding chapters will assist you in developing the skills and techniques used by real adversaries to identify vulnerable points of entry into an organization and mitigate reconnaissance-based attacks. By the end of this book, you’ll have gained a solid understanding of reconnaissance, as well as learned how to secure yourself and your organization without causing significant disruption.

Enumerating network services

During the host discovery phase of ethical hacking, many open ports and running services can be found. The information collected during the host discovery phase is used to perform additional research to find known security vulnerabilities within those running services and how they can be exploited to gain unauthorized access to a target. Enumerating network services on targeted systems helps ethical hackers and penetration testers to better understand the target’s network infrastructure and attack surfaces and which attack vectors can be used to deliver a payload to the target.

NetBIOS and SMB enumeration

Network Basic Input/Output System (NetBIOS) is an old legacy network protocol that’s commonly used within Windows-based environments for file and print sharing, and name resolution services on a Local Area Network (LAN). SMB is a newer network protocol that’s also used within Windows-based environments for file and print-sharing...
