Chapter-18, LEC-3 | Detailed Explanation of Methodology | #ethicalhacking #cybersport #cybersecurity
Hacker methodology is a detailed process used by cybercriminals to identify, exploit, and maintain unauthorized access to computer systems, networks, or data. This methodology typically involves several stages, each with its own set of tactics and techniques.
The first stage of hacker methodology is reconnaissance. This involves gathering information about the target system or network, such as IP addresses, network topology, and information about system users. Hackers may use tools like port scanners, network mappers, and social engineering tactics to obtain this information.
The next stage is scanning. Hackers use this stage to identify vulnerabilities in the target system or network. This may involve scanning for open ports, testing for weak passwords, or identifying outdated software that is vulnerable to attack.
The third stage is gaining access. Once vulnerabilities have been identified, hackers will attempt to exploit them to gain access to the target system or network. This may involve using techniques such as SQL injection, cross-site scripting, or phishing to obtain login credentials or other sensitive information.
Once access has been gained, the hacker will move to the fourth stage, maintaining access. This stage involves establishing a backdoor, or a method of maintaining access to the system even after the initial attack has been detected and blocked. This may involve installing malware, creating a new user account with elevated privileges, or modifying system files to hide their presence.
The final stage is covering tracks. This involves removing any evidence of the attack to avoid detection. Hackers may delete log files or modify system settings to remove any traces of their activity.
Understanding the hacker methodology is critical for developing effective security measures to protect computer systems and networks. By identifying potential weaknesses in the system, implementing strong access controls, and monitoring network traffic for signs of unauthorized activity, organizations can improve their defenses against cybercriminals.
