Phase 3: Gaining Access (Exploitation)

Cyber Security Mastery: From Zero to Hero

Module 5: Deep Dive into Tools and Techniques

Once reconnaissance and scanning reveal a potential vulnerability, the attacker moves to Exploitation (Gaining Access). This is the act of using an exploit to force a vulnerable system to behave in an unintended way, typically leading to remote code execution (RCE).

The Goal of Exploitation

The primary goal is to achieve a shell (a command-line interface) on the remote machine. This shell allows the attacker to execute commands as if they were physically logged into the target.

  • Bind Shell: The target system opens a listening port, and the attacker connects to it.
  • Reverse Shell: The target system connects back to a listening port on the attacker's machine. This is preferred, as outgoing connections are often less restricted by firewalls.

Key Tool: The Metasploit Framework is the most powerful tool for this phase.
