Ethical hackers use Metasploit, a powerful penetration testing framework, to identify and exploit vulnerabilities within a network. Here’s how they typically do it:
- Information Gathering: Ethical hackers start by collecting information about the target network. They use Metasploit’s auxiliary modules to scan for open ports, services, and system details. This helps in creating a profile of the network’s structure and potential points of entry.
- Vulnerability Scanning: Metasploit can integrate with vulnerability scanners like Nmap or Nessus to detect known vulnerabilities in the target systems. It identifies weaknesses such as outdated software versions, misconfigurations, and exposed services.
- Exploit Selection: Once vulnerabilities are identified, ethical hackers use Metasploit to search for matching exploits within its extensive database. Each exploit targets a specific vulnerability, such as a buffer overflow or an unpatched software flaw.
- Payload Configuration: Ethical hackers configure payloads, which are malicious code snippets delivered by exploits. Common payloads include Meterpreter, a powerful shell that provides remote control over the target system, and reverse shells that establish a connection back to the attacker’s machine.
- Launching the Attack: The exploit is launched using Metasploit, which delivers the payload to the target system. Successful exploitation grants the ethical hacker access to the system, where they can perform actions like privilege escalation, data extraction, or additional network reconnaissance.
- Post-Exploitation: After gaining access, ethical hackers use Metasploit’s post-exploitation modules to maintain control, gather further information, and pivot to other systems within the network.
By using Metasploit, ethical hackers can systematically identify and exploit vulnerabilities, helping organizations to understand their security weaknesses and improve their defenses.

A privilege escalation attack occurs when an attacker gains unauthorized access to higher levels of system privileges than those originally granted. This type of attack can be classified into two main categories: vertical and horizontal. Vertical Privilege Escalation: This involves moving from a lowRead more
