This article outlines 10 foundational ethical hacking techniques that security professionals use to identify and remediate vulnerabilities before malicious actors exploit them. The piece addresses the growing cybersecurity threat landscape and the industry demand for skilled ethical hackers by presenting a structured methodology covering reconnaissance, scanning, vulnerability assessment, password testing, social engineering, web application attacks, exploitation, privilege escalation, persistence, and evidence removal. Understanding these techniques matters because they form the core of penetration testing and security assessments used globally to strengthen organizational defenses.
- Reconnaissance establishes attacker perspectiveThe article identifies reconnaissance (information gathering) as the critical first phase where ethical hackers collect publicly available information about target systems, including domain information, email addresses, subdomains, server technologies, and employee details. This phase uses tools like Nmap, theHarvester, Recon-ng, and Maltego, and leverages Open Source Intelligence (OSINT) techniques to understand how a target system operates before attempting any direct attacks.
- Network scanning identifies entry pointsAfter reconnaissance, network scanning discovers active devices, open ports, running services, and operating systems on target networks. The article explains that common scanned ports include FTP (21), SSH (22), HTTP (80), and HTTPS (443), noting that each open port represents a potential entry point for attackers. Nmap is identified as the most widely used tool for this phase among penetration testers.
- Vulnerability scanning finds security weaknessesThis technique systematically identifies security flaws in systems and applications, including outdated software, weak security settings, missing patches, and default passwords. The article names tools like Nessus, OpenVAS, and Nikto, and references security frameworks from OWASP, NIST, and MITRE ATT&CK that organizations use to understand modern threats.
- Password cracking tests authentication strengthThe article describes three specific password cracking approaches: brute force attacks (trying every possible combination), dictionary attacks (using common password lists), and rainbow table attacks (using precomputed hash values). Tools like John the Ripper, Hashcat, and Hydra are mentioned as commonly used for this purpose.
- Social engineering targets human vulnerabilitiesThe article distinguishes this technique from technology-focused attacks, explaining that social engineering exploits people rather than systems through methods like phishing emails, fake login pages, vishing (phone scams), and fake technical support. The piece notes that many of the largest cybersecurity breaches began with a simple phishing email.
- Web application attacks exploit common flawsThe article identifies SQL Injection, Cross-Site Scripting (XSS), file upload vulnerabilities, and authentication bypass as security flaws in web applications. Tools like Burp Suite, OWASP ZAP, and SQLmap are presented for testing web security, with the article emphasizing that learning web security is particularly valuable for beginner ethical hackers.
- Privilege escalation expands system controlAfter gaining initial access, attackers attempt to increase their privileges by exploiting misconfigured permissions, kernel vulnerabilities, and weak services. The article explains that this progression from limited user account permissions to full administrator control allows attackers to gain complete system dominance.
- Post-exploitation and cover-up maintain persistenceThe article describes how attackers maintain access through installing backdoors, creating hidden user accounts, and deploying remote access tools, then conceal their activities by deleting logs, obfuscating malware, and clearing command history. Understanding these final stages helps cybersecurity teams improve forensics and intrusion detection capabilities.
Bottom line: Mastering the 10 techniques presented—from reconnaissance through covering tracks—provides beginners with the structured methodology that professional penetration testers use to assess security and help organizations defend against real-world attacks. The article emphasizes that these techniques form a complete attack chain that security professionals must understand to effectively identify and remediate vulnerabilities before attackers exploit them.

Ethical Hacking Techniques Every Beginner Must Understand
Ethical hacking techniques are used by cybersecurity professionals to identify vulnerabilities before attackers exploit them. These techniques follow a structured methodology used in penetration testing and security assessments.
Below are the 10 most important ethical hacking techniques beginners should learn.
1. Ethical Hacking Techniques #1: Reconnaissance (Information Gathering)
Before attacking a system, hackers collect as much information as possible.
This step is called reconnaissance, also known as information gathering.
Think of it like a detective collecting clues before solving a case.
Hackers try to discover:
- Domain information
- Email addresses
- Subdomains
- Server technologies
- Employee information
This process helps hackers understand how a target system works before attempting an attack.
Beginner Tools for Reconnaissance
• Nmap
• theHarvester
• Recon-ng
• Maltego
Many professional hackers also use OSINT (Open Source Intelligence) techniques to gather publicly available information.
2. Ethical Hacking Techniques #2: Network Scanning
After gathering information, hackers move to the next stage called network scanning.
Network scanning helps identify:
- Active devices on the network
- Open ports
- Running services
- Operating systems
Each open port can potentially become an entry point for attackers.
Some commonly scanned ports include:
| Port | Service |
|---|---|
| 21 | FTP |
| 22 | SSH |
| 80 | HTTP |
| 443 | HTTPS |
Beginner Tool
The most popular tool used for network scanning is Nmap, which is widely used by penetration testers worldwide.
3. Ethical Hacking Techniques #3: Vulnerability Scanning
Vulnerability scanning is used to identify security weaknesses inside systems, applications, or networks.
Some common vulnerabilities include:
- Outdated software
- Weak security settings
- Missing security patches
- Default passwords
Attackers scan systems looking for known security flaws that can be exploited.
Popular Vulnerability Scanners
• Nessus
• OpenVAS
• Nikto
Many organizations also follow security guidelines from organizations like OWASP, NIST, and MITRE ATT&CK to understand modern threats and vulnerabilities.
4. Ethical Hacking Techniques #4: Password Cracking
Passwords are one of the weakest points in many security systems.
Hackers use various techniques to break weak passwords.
Common Password Cracking Techniques
- Brute Force Attack – Trying every possible password combination until the correct one is found.
- Dictionary Attack – Using a list of common passwords to guess credentials.
- Rainbow Table Attack – Using precomputed hash values to crack passwords quickly.
Most Popular Tools Used are:
• John the Ripper
• Hashcat
• Hydra
5. Social Engineering (Hacking Humans)
Not every cyberattack targets technology.
Sometimes hackers target people instead of systems.
This technique is called social engineering.
Examples include:
- Phishing emails
- Fake login pages
- Phone scams (vishing)
- Fake technical support
Many of the largest cybersecurity breaches started with a simple phishing email.
6. Web Application Hacking
Web applications are among the most common targets for hackers.
Ethical hackers test websites for security flaws such as:
- SQL Injection
- Cross-Site Scripting (XSS)
- File upload vulnerabilities
- Authentication bypass
Tools Used for Web Security Testing
• Burp Suite
• OWASP ZAP
• SQLmap
Learning web security is one of the most valuable skills for beginner ethical hackers.
7. Exploitation
After identifying vulnerabilities, hackers attempt to exploit them.
Exploitation means using a vulnerability to gain unauthorized access to a system.
For example:
If a server has a known vulnerability, attackers might use an exploit to run commands remotely.
Popular Exploitation Tool
Metasploit is widely used by penetration testers to simulate real-world attacks.
8. Privilege Escalation
After gaining initial access to a system, attackers attempt to increase their privileges. This process is called privilege escalation.
For Example: A user account may have limited permissions, but an administrator account has full control. Attackers search for vulnerabilities that allow them to escalate privileges.
Attackers exploit:
- Misconfigured permissions
- Kernel vulnerabilities
- Weak services
Privilege escalation allows attackers to gain full control of a system.
9. Post-Exploitation
Post-exploitation focuses on maintaining access to compromised systems. Attackers may install backdoors or remote access tools to ensure continued control.
Ethical hackers analyze post-exploitation scenarios to understand how attackers maintain persistence.
Methods include:
- Installing backdoors
- Creating hidden user accounts
- Deploying remote access tools
10. Covering Tracks
Advanced attackers attempt to hide evidence of their activities. This process may involve deleting logs, modifying files, or disguising malicious software.
Understanding this stage helps cybersecurity teams improve digital forensics and intrusion detection systems.
Common techniques include:
- Deleting system logs
- Obfuscating malware
- Clearing command history
