Introduction
With the increasing number of organizations shifting to the digital world, the importance of protecting data from hacking and cyber-attacks has become more critical than ever. Many companies are now recognizing the potential risks associated with these attacks and considering proactive measures, such as ethical hacking. But how can ethical hacking help in saving organizations from such attacks? Phases of ethical hacking comprise some crucial steps that ethical hackers take in order to find vulnerabilities and take security measures in order to protect data.
In this blog, we will mainly focus on Ethical Hacking, the 5 phases of ethical hacking, and frequently asked questions. Let’s Begin!
What is Ethical Hacking?
The goal of ethical hacking is to get a better knowledge of a system’s security by exploiting its weaknesses in a controlled environment. When conducting an ethical hack, a security expert or researcher acts similarly to a malicious hacker. This helps in the early detection and identification of security concerns, making it harder for hackers to exploit.
If you want to learn ethical hacking beyond theory and understand how professionals actually test systems, a structured learning approach makes a big difference.
Importance of Ethical Hacking
Ethical hacking is important because it allows networks to be protected from cyber threats and is a specific type of penetration testing run for security purposes.
Three major importance of ethical hacking are given below:
- It helps you detect all the vulnerabilities in your network, allowing you to resolve vulnerabilities before criminals or hackers can cause harm quickly.
- It is used to analyze weak areas in your network and improve its security by installing stronger security measures.
- It allows for training to be provided to employees regarding cybersecurity issues, ensuring that they do not fall victim to scams or other threats.
Types of Ethical Hacking
Common types of ethical hacking are given below:
- Web application hacking: It is the process of exploiting software on HTTP by exploiting the software’s visual Chrome browser, interfering with URIs, or conspiring with HTTP features not available in the URI.
- System hacking: Attackers use system hacking to get access to personal computers on the network. The IT security professionals counter these attacks with defensive measures such as password busting, privilege escalation, malicious software creation, and packet sniffing.
- Web Server Hacking: Web information created by application software databases in real-time. Therefore, attackers obtain credentials, passcodes, and company details from web applications through gluing, ping deluge, port scans, sniffing attacks, and social engineering techniques.
- Hacking Wireless Networks: This happens because wireless networks use radio waves while sharing data; through this, attackers can easily stream into the system from a nearby location. Typically, attackers use network snorting to locate, and bypass detected wireless networks.
- Social Engineering: Social engineering allows the public to be manipulated into revealing sensitive information, and attackers use eugenics because attacking trust in difficult times is easier than figuring out how to trick devices.
We now have a basic understanding of ethical hacking; let’s understand the phases of ethical hacking and how they assist in minimizing the attacks.
What are the 5 Phases of Ethical Hacking?
Ethical hackers are employed by organizations to replicate the effects of a cyberattack on their systems as well as networks. Ethical hackers need a lot of knowledge and expertise before they can find every vulnerability and use them to their advantage.
The purpose of this hypothetical attack is to draw attention to all of the enterprise’s weak points and address how to strengthen these weak points. The 5 phases of ethical hacking are:
- Reconnaissance
- Scanning
- Gaining Access
- Maintaining Access
- Covering Track
However, every ethical hacker doesn’t need to follow the above-discussed phases in a similar order. Now, let’s understand the phases of ethical hacking in detail.
1. Reconnaissance
Reconnaissance is also called “footprinting or penetration testing.” The main goal is to learn as much as possible about the target before directly attacking it. This reduces risk for the attacker and increases the chance of success.
During reconnaissance, attackers commonly try to learn things like:
- Public IP ranges and domains used by the organization
- DNS records (subdomains, mail servers, name servers)
- Employee names, email formats, and roles (useful for phishing/social engineering)
- Technology used (cloud provider, web frameworks, VPN portals, remote access tools)
- Third-party vendors who may have access (supply-chain risk)
In this stage, the ethical hacker has two options for gathering information. These are:
- Active reconnaissance: Active reconnaissance is a deliberate effort to look for information regarding the target network system, server, or application to increase the possibility of the hacker’s exposure inside the system.
- Passive reconnaissance: Passive reconnaissance is the stealthier method of gathering intelligence. This includes looking for IP addresses and other crucial information and obtaining data on the company’s main members and significant details.
Ethical hackers may find it simple to acquire information passively about a target business since almost all of that firm’s data is available to the public.
2. Scanning
After reconnaissance, the second phase of ethical hacking is scanning. This phase involves applying the data gathered during reconnaissance to the process of searching for security vulnerabilities in the intended location. Also, scanning is the step where “collected information” becomes “technical confirmation.” For example, scanning helps confirm which hosts are alive, which ports are open, what services/versions are running, and where the biggest weaknesses might exist.
- Network scanning: It involves the identification of the network topology, covering important information such as hosts, firewalls, servers, and routers within the host network. Once the mapping process is complete, white hat hackers can visualize and plan strategically to determine the subsequent actions in the ethical hacking process.
- Port scanning: Ethical hackers employ automated tools to identify any open ports within the network. This feature enables an efficient method for enumerating the services and live systems within a network and establishing connections with these components.
- Vulnerability scanning: It is used to identify vulnerabilities and weak points within a target system and thereafter exploit these bugs through various means. The process is executed utilizing automated tools such as Nmap, OpenVAS, Netsparker, and various others.
3. Gaining Access
After gathering and analyzing as much data as possible in the first two phases, the ethical hacker next launches a full-scale assault on the target system or network. They use all the vulnerabilities they find to take over the machine in order to achieve administrative access.
In the third phase, an attacker tries to deliver a malicious payload to the application by communicating with it across the network, a neighbouring subnetwork, or a locally connected computer. To fake an effort at breaking in, hackers often employ a wide variety of hacking tools and methods, including:
- Injection attacks
- Buffer overflows
- XML external entity
After from the hacking tools, some common ways attackers gain access include (high-level):
- Using stolen or weak passwords
- Abusing misconfigurations (especially in cloud and web apps)
- Exploiting software vulnerabilities to run code or steal sessions
- Phishing or other social engineering to make a user run malware or reveal credentials
Real World Case – (Sony Pictures, 2014): the U.S. Department of Justice described conspirators gaining access by sending malware to employees, followed by theft and damage. This is commonly referenced as a case where initial access was linked to malware delivery to staff.
4. Maintaining Access
When breaking into a company’s network, hackers often have some goal in mind or strategy to carry it out. This implies that illegally entering or hacking into the system won’t be sufficient. The ethical hacker must maintain access to the system or network until they achieve their objective. Ethical hackers often accomplish this step using Trojans or other backdoors/rootkits. During this time of keeping access, they may also launch more attacks on the company.
Maintaining access is about persistence (staying in the environment) and also about reliability (being able to come back even if one path is closed). In real incidents, this can include creating alternate access paths, abusing legitimate admin tools, or planting malware that reconnects.
This phase is often associated with long-term attacks (APT-style behavior), where attackers stay hidden for weeks or months to collect data or wait for the “right time.”
5. Covering Tracks
Covering tracks” is also called “clearing tracks”. The goal is to make detection and investigation harder (for example, by hiding tools, changing timestamps, reducing visible traces, or attempting to blend in with normal activity). Hackers carry out steps to remove all signs of their harmful behaviour so that no one can trace their actions back to them. These are:
- Clearing logs
- Uninstalling scripts or applications that were used to carry out attacks
- Modifying registry values
Important point: Even if local logs are altered, organizations may still have other evidence (central logging, backups, network telemetry, cloud audit trails). That’s why defenders often correlate multiple sources instead of relying on a single machine’s log.
The vast majority of hackers who want to remain undiscovered use methods such as tunnelling and various others.
Real-world Case – (Capital One, 2019): Capital One states the incident was investigated after a report through their disclosure process and then involved law enforcement—showing that external reporting plus investigation can uncover activity even when attackers try to stay unnoticed.
After completing all 5 phases of ethical hacking, the ethical hacker will write a report detailing the vulnerabilities and provide recommendations for fixing them.
Why each Phase of Ethical Hacking is Critical?
Each phase of Ethical Hacking builds upon the last one. This ensures a systematic and thorough approach to fund any vulnerabilities and address them to secure the system.
If you skip even one phase, there are chances of leaving some vulnerabilities undiscovered. So, each phase is important in finding the vulnerabilities of the system and addressing them timely.
Tools Commonly Used in Ethical Hacking Phases
There are various tools used by ethical hackers at different phases of Ethical Hacking. Some of these tools are:
- Nmap: An open-source tool that is used for network discovery and security auditing. It helps in identifying open ports, services, and vulnerabilities on devices within the network.
- Metasploit: It is a popular penetration testing tool that is used to assess security vulnerabilities.
