Cyberattacks exploiting network vulnerabilities, such as those facilitated by the framework Metasploit , represent a
growing threat in 2025, with a 10% increase in weaponized vulnerabilities ( Recorded Future, 2025). This study explores the
mechanisms of cyberattacks, focusing on Metasploit exploits such as EternalBlue (MS17-010), their economic impacts (10.5 billion
USD/year), and their technical implications. Through simulated tests in a controlled environment, we analyze the attack stages:
reconnaissance, exploitation, and post-exploitation. We propose network partitioning as a mitigation solution, limiting the lateral
propagation of threats. Our results show that segmentation reduces unauthorized access by 80% in Meterpreter -like scenarios .
Drawing on academic and industrial sources, this article aims to educate professionals on proactive defenses, while respecting
research ethics.
