"Hacker methodology" typically refers to the processes and techniques that hackers use to gain unauthorized access to computer systems, networks, and data. It's essential to clarify that hacking can be both ethical and malicious, with ethical hackers, often referred to as "white hat" hackers, using their skills to help secure systems and networks. Malicious hackers, known as "black hat" hackers, use their skills for illegal or harmful purposes.
Here's a high-level overview of the general steps or stages in a hacker's methodology:
1. Reconnaissance (Information Gathering): This is the initial phase where hackers gather information about their target. It can involve passive techniques like researching the target online or actively probing for vulnerabilities through methods like port scanning.
2. Scanning: In this phase, hackers identify potential entry points by scanning the target's network for open ports, services, and vulnerabilities. Tools like Nmap are often used for this purpose.
3. Enumeration: Once potential entry points are identified, the hacker attempts to gather more information about the system. This can involve querying the target for additional information, such as user accounts or system details.
4. Vulnerability Assessment: In this step, the hacker searches for known vulnerabilities in the target system or application. This might involve using automated vulnerability scanning tools or manually searching for weaknesses.
5. Exploitation: If a vulnerability is found, the hacker exploits it to gain unauthorized access. This could involve running scripts or using software exploits to compromise the target.
6. Maintaining Access: After gaining access, the hacker may establish a persistent presence on the compromised system by creating backdoors, rootkits, or other mechanisms to ensure continued access.
7.Covering Tracks:To avoid detection, the hacker tries to remove any evidence of their presence on the compromised system. This might include deleting logs, altering timestamps, or obfuscating their activities.
8. Exfiltration:If the hacker's goal is to steal data, they will attempt to transfer or exfiltrate the desired information without raising suspicion.
9. Post-Exploitation: In some cases, the hacker may explore the compromised network further, escalate privileges, or move laterally within the network to compromise additional systems.
It's important to emphasize that understanding this methodology can help organizations and cybersecurity professionals defend against hacking attempts. Ethical hackers, or "white hat" hackers, also follow a similar methodology to identify and fix vulnerabilities, helping organizations improve their security. This field of ethical hacking is known as penetration testing or "pen testing."
