The presence of SMB (port 445) and MSRPC (port 135) indicates potential Windows network services that could be vulnerable to misconfigurations or exploits.
Enumerate shares and search for vulnerabilities on SMB (Option B):
SMB (Server Message Block) allows file and printer sharing. Misconfigured or open shares could contain sensitive data.
Tools like enum4linux or smbclient can be used to list available shares and check for anonymous access.
SMB vulnerabilities (e.g., EternalBlue - CVE-2017-0144) can be exploited for remote code execution.
Reference: CompTIA PenTest+ PT0-003 Official Study Guide - "SMB Enumeration and Exploitation" Incorrect options:
Option A (Search vulnerabilities on msrpc): MSRPC (Microsoft Remote Procedure Call) is not commonly exploited directly unless an SMB or RDP vulnerability is found.
Option C (Brute-force RDP): Brute-force attacks generate excessive failed login attempts, triggering security alerts.
Option D (Search for another port): The open ports already provide sufficient attack vectors.
