Introduction
Penetration testing, also known as ethical hacking, is a crucial process in ensuring the security of computer systems and networks. It involves simulating real-world cyberattacks to identify potential vulnerabilities and weaknesses in an organisation’s IT infrastructure. One of the initial and most critical phases in the penetration testing process is reconnaissance. In this blog, we will delve into the various aspects of reconnaissance in penetration testing, including passive reconnaissance, active reconnaissance, and the tools commonly used during this phase. Additionally, we will explore how 3 columns, a leading cyber security company based in Australia, can be beneficial to any organisation seeking to bolster its security measures.
Understanding Reconnaissance
Reconnaissance is the preliminary phase of a penetration test where testers gather information about the target organisation, its network architecture, and potential vulnerabilities without actively engaging with the systems. The primary goal of reconnaissance is to build a comprehensive profile of the organisation’s digital footprint, which can be leveraged later to devise targeted attack strategies.
Passive Reconnaissance
Passive reconnaissance involves collecting information from publicly available sources without directly interacting with the target’s systems. This method ensures that the organisation’s security is not compromised during the information-gathering process. Techniques used in passive reconnaissance include:
A. Open-source intelligence (OSINT):
Utilising publicly accessible data from the internet, social media, and other sources to gather information about the organisation, its employees, and other relevant data.
B. DNS enumeration:
Extracting Domain Name System (DNS) records to identify subdomains, mail servers, and other critical infrastructure components.
C. WHOIS lookup:
Retrieving registration information about the organisation’s domain name, including the domain owner’s details.
Active Reconnaissance
Active reconnaissance involves engaging with the target’s systems to obtain more detailed information. Unlike passive reconnaissance, this phase can be riskier as it might trigger security alerts and raise suspicion. Techniques used in active reconnaissance include:
A. Port scanning:
Identify open ports on the target’s systems to understand potential points of entry.
B. Banner grabbing:
Gathering information about services and software versions running on the exposed ports.
C. Network scanning:
Mapping the organisation’s network infrastructure to identify potential vulnerabilities and weak points.
Tools Used in Reconnaissance
Numerous tools are available to assist penetration testers in conducting reconnaissance effectively. Some popular tools include:
Nmap:
A powerful open-source network scanning tool used for port scanning, host discovery, and service version detection.
TheHarvester:
A tool for gathering emails, subdomains, and other relevant information from public sources.
Shodan:
A search engine that indexes information about internet-connected devices, making it useful for reconnaissance purposes.
Recon-ng:
A powerful reconnaissance framework that combines various techniques and modules for efficient information gathering.
