In this book, you will Learn about service exploitation through open ports. you learn port Exploitation with Metasploit, you say about hack anything with IP.Open ports become dangerous when legitimate services are exploited through security vulnerabilities or malicious services are introduced to a system via malware or social engineering, cybercriminals can use these services in conjunction with open ports to gain unauthorized access to sensitive data. There's a common misconception that an open port is dangerous. This is largely driven by a lack of understanding of how open ports work, why they are open, and which ones shouldn't be open. Attackers use open ports to find potential exploits. To run an exploit, the attacker needs to find a vulnerability. To find a vulnerability, the attacker needs to fingerprint all services that run on a machine, including what protocols it uses, which programs implement them, and ideally the versions of those programs. To do this, attackers commonly rely on finding a publicly accessible port via port scanning.
