The EC-Council 212-81 exam, covering the Certified Ethical Hacker (CEH) v12 curriculum, covers a broad range of cybersecurity topics. The main points can be grouped into these key areas:

I. Footprinting and Reconnaissance:

• Active vs. Passive Footprinting: Understanding the difference and techniques used in each.
• Network Footprinting: Identifying network devices, services, and vulnerabilities.
• Host Footprinting: Gathering information about specific hosts.
• DNS Enumeration: Discovering DNS records and related information.
• Social Engineering Techniques: Gathering information through manipulation of individuals.

II. Scanning Networks:

• Network Scanning Techniques: Using tools like Nmap and Nessus to identify open ports and vulnerabilities.
• Vulnerability Scanning: Identifying potential security weaknesses in systems and applications.
• Port Scanning: Enumerating open ports and services on target systems.
• OS Fingerprinting: Identifying the operating system of target systems.
• Service Detection: Determining the services running on target systems.

III. Enumeration:

• Enumerating Users and Groups: Identifying users and their associated privileges.
• Enumerating Shares and Files: Discovering shared resources and their contents.
• Enumerating Network Devices: Identifying devices on a network and their configurations.
• Password Cracking: Utilizing various techniques to crack passwords.

IV. System Hacking:

• Exploiting Vulnerabilities: Using known vulnerabilities to gain unauthorized access.
• Privilege Escalation: Gaining higher-level access within a system.
• Trojan Horses and Backdoors: Understanding and utilizing these malicious tools.
• Rootkits and Keyloggers: Recognizing and removing these malicious programs.

V. Malware Threats:

• Types of Malware: Understanding the characteristics and effects of various malware types (viruses, worms, trojans, etc.).
• Malware Analysis: Methods for identifying and analyzing malicious software.
• Anti-Malware Techniques: Strategies for preventing and mitigating malware infections.

VI. Sniffing and Eavesdropping:

• Network Sniffing: Intercepting network traffic to obtain sensitive information.
• Eavesdropping Techniques: Methods for intercepting communications.
• Wireless Attacks: Exploiting vulnerabilities in wireless networks.

VII. Session Hijacking:

• Session Hijacking Techniques: Methods for stealing and exploiting active user sessions.
• ARP Poisoning: Manipulating ARP tables to redirect network traffic.
• DNS Spoofing: Redirecting traffic to malicious websites.

VIII. Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks:

• DoS and DDoS Attack Methods: Understanding how these attacks work and their implications.
• Mitigating DoS and DDoS Attacks: Strategies for preventing and responding to these attacks.

IX. Social Engineering:

• Phishing, Baiting, Pretexting, Quid Pro Quo, etc.: Understanding different social engineering techniques.
• Building rapport and trust: Learning how attackers establish trust to gain access.

X. SQL Injection:

• SQL Injection Techniques: Understanding how to exploit vulnerabilities in database applications.
• Preventing SQL Injection: Implementing security measures to prevent SQL injection attacks.

XI. Web Hacking:

• Cross-Site Scripting (XSS): Understanding how to exploit XSS vulnerabilities.
• Cross-Site Request Forgery (CSRF): Understanding how to exploit CSRF vulnerabilities.
• Other Web Application Vulnerabilities: Exploring various attack vectors against web applications.

XII. Legal Issues and Ethics:

• Ethical Hacking: Understanding the principles and responsibilities of ethical hacking.
• Legal Considerations: Awareness of legal implications when conducting security assessments.

This list summarizes the core areas. Each topic encompasses numerous subtopics and specific tools and techniques. Preparation requires a thorough understanding of all these areas and substantial hands-on practice.
