Definitions

  • Black Hat Hacker: An individual who uses their technical skills for malicious purposes, such as unauthorized access or theft of data.

  • Penetration Testing (Pen Testing): The practice of simulating cyberattacks on a system to identify and address security vulnerabilities before they can be exploited by malicious actors.

  • Brute Force Attack: A method of hacking that involves systematically trying all possible passwords or encryption keys until the correct one is found.

  • White Hat Hacker (Ethical Hacker): A cybersecurity expert who uses their skills to help organizations improve their security by identifying and fixing vulnerabilities legally and ethically.

  • Network Scanning: The process of discovering active devices and services on a network and identifying potential security weaknesses.

  • Payload: The part of a malicious attack or exploit that performs the intended action, such as executing a command or delivering a malicious payload.

  • Kali Linux: A specialized Linux distribution designed for penetration testing and cybersecurity research, including a wide range of security tools and utilities.

  • JacktheRipper: A common misnomer for "John the Ripper," a password cracking tool used to perform brute force and dictionary attacks on hashed passwords.

  • Ethical Hacking: The practice of legally and ethically testing and evaluating systems and networks to identify security weaknesses and improve overall security.
